Description

  The present invention is a laying construction method capable of preventing the occurrence of wrinkles and sagging of an overlay placed on a carpet floor.

  Conventionally, there are various methods for preventing the occurrence of wrinkles and sagging of the overlay placed on the carpet floor, but the present invention has a different concept. The conventional construction technique is an idea to solve the problem by a construction method that utilizes individual performance effects in a single body. In the present invention, by laying and laminating two types of individual nonwoven fabrics which cannot prevent wrinkles and sagging in a single body, one performance effect different from each original performance is produced, and this newly generated Therefore, the technical background of the conventional method is not useful. If each non-woven fabric is returned to the original single body before construction, the single body returns to its original performance.

Detailed Description of the Invention

Conventional technology

Place the overlay on the carpet floor. And when a human or animal walks on it, this overlay moves and generates wrinkles and sagging. About 50 years after the inventor and his family became aware of this problem, the prototype was examined for the development of the construction method of the laying construction that does not cause this phenomenon on the carpet placed on the carpet floor. The experience and knowledge of the inventor and his family are: Synthetic cotton manufacturer working for interior / bedding supplies route, carpet manufacturer sales, interior / interior materials sales, carpet construction Based on duty, carpet cleaning business duties.
Naturally, carpet manufacturers, distributors, contractors, scholars, specialists, etc. have been engaged in the development of construction methods for laying construction that does not cause this phenomenon to appear on the carpet placed on the carpet floor. The final conclusion that can be put to practical use is a method of using a product that prevents this currently on the market. There are the following various methods that have been devised and marketed so far in order to prevent the occurrence of slippage and sagging. The basis of the construction method is to obtain the performance effect with a single product and to use the principle of stab or paste.

  Because the explanation is complicated, the top cover is (1) Oriental rug (Kilim, Persian carpet, Gabbe, Chinese step, Yamagata step, etc.), Belgian carpet and other space rugs, and the top cover is (2) The description will be divided into the case of a sheet of vinyl chloride resin, a sheet of polyolefin resin, or a simple carpet rug having a waterproof effect. The methods that have been devised and marketed so far to prevent the occurrence of wrinkles and sagging that occur in these overlays will be listed, and the problems of each method will be shown. The conventional construction method has a defect, which hinders the possibility of selling an overlay on the floor and the sale of carpet as a flooring.

(1) For oriental rugs (kilim, persian carpet, gabbe, Chinese stepping, Yamagata stepping, etc.), Belgian carpets, and other rugs such as space rugs:
Oriental rugs, Belgian carpets, and other space rugs are laid directly on the carpet floor, and when a person walks on them, these rugs move and wrinkles and sagging occur. There is a danger of falling if a human is stepped on these traps and slacks. Moreover, this occurring situation worsens the aesthetics of the room. Various construction methods have been devised so far to prevent the covering from moving and generating wrinkles and sagging.

◎ Net-like thickness of about 1mm to 2mm hard plastic sheet, on the front and back surfaces, about 3 to 5mm high roots of conical stab-like protrusions with a diameter of about 2mm, front and rear, about 5cm Molded at intervals. A method of installing this sheet between the top floor and the carpet floor.
<Problem of this construction method> With the barbs on both sides of this sheet, the barb on one side pierces the pile surface of the carpet floor and stops the movement of this facing surface.
The thorn on the opposite side of this sheet is a way to stab the back of the top rug and stop the movement of this facing surface.
When the overlay is a silk carpet having a total thickness of about 5 mm including the pile (hairs), the thorn touches the sole of the foot from the surface side of the silk carpet. Most kilim rugs have a total thickness of 5 mm or less, and touch the sole from the surface side. If you are barefoot, you will be injured. Because the sheet is made of hard plastic, it does not fit well with the underlying carpet floor, and the sheet is flat and rigid, so if the underlying carpet floor is elastic and the overlay is light, a human walking foot As the weight is repeatedly applied, the surface of the unweighted portion is lifted, and the carpet floor side barb (thorn) may come off or move.

◎ A method of installing a sheet of approximately 1mm thick, which is a 100% lace-knitted mesh-like polyester fiber impregnated with a large amount of acrylic adhesive resin, between the top floor and the carpet floor.
<< Problem of this construction method >> This is a 100% lace-knitted mesh-like polyester fiber sheet impregnated with a large amount of adhesive resin, cut into the same size as the overlay, placed on the carpet floor, and the sheet with the adhesive resin Put the top rug on top. Adhesive strength is so strong that one side sticks to the carpet floor pile and the other side sticks to the back of the top laying.
This adhesive resin-attached sheet has a very strong adhesive force, and when it is rolled up and stored, the adhesive fabrics that overlap each other are stuck together and may be wound with a release paper inside. The damage caused by aging is that a slight amount of gas and plasticizer oozing out of the adhesive resin of this sheet placed under the overlay affects the carpet floor pile, and the pile on a thin white background In the case of (hairy feet), this is yellowing. In the case where the floor of the carpet floor is constructed by the floor heating method, the temperature condition is added and this phenomenon is caused more.
When the adhesive strength of this sheet with adhesive resin is very strong, it is necessary to use an oriental rug hand weaving type on the top cover and a specific weaving method that does not use a pile (hair foot) fixing adhesive on the back side. The base of the pile (hairy feet) on the back and the sheet with the adhesive resin stick strongly, and when the topsheet and this sheet are separated, the pile (hairy feet) of the overlay may be pulled out. is there.

◎ A method of placing a sheet of polyester fiber staple fiber (short fiber) 100% thick about 2 to about 6 mm in which a non-woven fabric is impregnated with a large amount of acrylic adhesive resin on the front and back surfaces, between the overlay and the carpet floor.
<< Problem of this construction method >> This is a 100% polyester fiber non-woven fabric that has been coated or impregnated with a large amount of adhesive resin on both surfaces. Cut it into the same size as the overlay and place it on the carpet floor. Place the overlay on the non-woven fabric. Adhesive strength is so strong that one side sticks to the carpet floor pile and the other side sticks to the back of the top laying.
Since this sheet has a very strong adhesive force, when it is rolled and stored, the overlapping non-woven fabrics stick together and may not be separated from each other. The damage caused by aging is that a slight amount of gas and plasticizer oozing out of the adhesive resin of this sheet placed under the overlay affects the carpet floor pile, and the pile on a thin white background In the case of (hairy feet), this is yellowing. In the case where the floor of the carpet floor is constructed by the floor heating method, the temperature condition is added and this phenomenon is caused more.
If the adhesive strength of this adhesive nonwoven fabric is very strong, the base of the oriental rug on the overlay is strongly adhered to the base of the pile (hair foot) of the overlay on the back of the overlay and the nonwoven fabric with adhesive resin When the overlay and the nonwoven fabric are pulled apart, the pile (hair foot) of the overlay may be pulled out.

◎ A sheet of about 1 mm in thickness obtained by foaming and fixing a vinyl chloride resin to a 100% polyester fiber base fabric made of net is pasted to a nonwoven fabric of about 1 mm to 2 mm in thickness. The foamed surface of the vinyl chloride resin is impregnated or sprayed with a small amount of adhesive resin, and the nonwoven fabric surface is impregnated or sprayed with a large amount of adhesive resin. A method of installing this sheet between the top floor and the carpet floor.
<Problem of this construction method> Cut this sheet into the same size as the overlay. The sheet surface side with a thickness of about 1 mm to which the vinyl chloride resin is fixed by foaming is impregnated or sprayed with a small amount of an adhesive resin, and this surface faces the back surface of the overlay. The non-woven fabric surface side having a thickness of about 1 mm to 2 mm impregnated or sprayed with a large amount of adhesive resin is a method of laying facing the carpet floor surface.
Since the foamed sheet surface side of the vinyl chloride resin is combined with the back surface of the overlay, this surface is less prone to slippage and wrinkles and sagging due to the anti-slip effect. There is no one on the market that has been coated with a large amount of adhesive resin to cause the pile (hairy feet) to slip out from the back side of the overlay. When the non-woven fabric side is firmly adhered to the carpet floor (the non-woven fabric side impregnated or coated with a large amount of adhesive resin), there is no occurrence of wrinkling or sagging of the overlay. However, when the carpet floor is subjected to felt gripper construction and the felt of the base is added to increase the cushioning property, even if the amount of impregnation or spraying is the same, the adhesiveness is relatively reduced as compared with the carpet floor having less cushioning property. When the tackiness is weak or weak, the overlay is moved by rubbing the pressure-sensitive adhesive attached to the nonwoven fabric against the pile on the carpet floor. The metastasis adheres to the foot). Then, the top covering moves and wrinkles and sagging occur. I see many complaints on the market.
When stocking this sheet product, roll it up and store it. Accordingly, in some cases, a large amount of impregnated resin is impregnated or coated with a release paper bitten in such a manner that the adhesive surface does not destroy the foam sheet surface. It is difficult to store without release paper.
Damage caused by aging is the slight gas generated from the adhesive resin used in this adhesive sheet and the oozing out of plasticizer affects the pile on the carpet floor. May turn yellow. In the case where the floor of the carpet floor is constructed by the floor heating method, the temperature condition is added and this phenomenon is caused more.

◎ There is a sheet or tape with one surface having a male needle-like protrusion of a surface fastener having a height of 4 to 5 mm. And the adhesive is apply | coated to the smooth surface of the back surface of this planar fastener. A method in which this adhesive surface is attached to the back side of the top cover, and the top cover is placed on the carpet floor.
<< Problem of this construction method >> The back side of the sheet or tape with the adhesive is attached to the back side of the overlay and fixed. Affix it on the entire back surface of the top cover or affix it to the appropriate area on the back of the top cover while observing the movement of the top cover and the degree of displacement. This sheet or tape has a very strong adhesive force, so if you have a specific weaving type that uses an oriental rug hand-woven type on the back and does not use pile-fixing adhesive on the back, The base of the pile (hair foot) of the overlay that comes out and the sheet with the adhesive resin adhere strongly, and the pile (hair foot) of the overlay may be pulled out when the cover and the sheet are separated.
In addition, Oriental rugs produced in the Middle East (for example, hand-woven overlays from India, Pakistan, Turkey, and Iran) are placed directly on the carpet floor, depending on the time, temperature and humidity conditions, the color of the Oriental rug dye. May have been transferred to the carpet floor. For this reason, in the gaps where the sheet or tape is not applied, the oriental rug is in direct contact with the pile (hairs) of the carpet floor, and this migration phenomenon may be damaged.

◎ A construction method in which a plywood board is installed on the entire surface between the overlay and the carpet floor.
<< Problem of this construction method >> In the method of laying and placing a board, since a new board is provided on the carpet floor, there is a level difference between the hard floor and the soft floor. Even in the case of a plate that can be moved easily, it takes effort to move. Also, if this is plywood, the woody color may be transferred to the carpet floor if it is unpainted. Alternatively, when the adhesive gas in the plywood diverges, the underlying carpet floor surface may turn yellow.

◎ A method of installing double-sided tape for carpet with adhesive used between carpeting and carpet flooring, which is used for carpet laying (solid construction on hard flooring).
<< Problem of this construction method >> The carpet double-sided tape with the adhesive passes with time and transfers the adhesive to both the overlay and the carpet floor, and the adhesive is cured. Finding this at a later date and removing this hardened adhesive requires a solvent, often causing harm to the overlay and carpet floor.
This double-sided tape has a very strong adhesive force, so if it is a hand-woven type of oriental rug on the top cover and does not use a pile (hair foot) fixing adhesive on the back side, it will appear on the back side of the top cover. The top of the top pile (hair feet) and the carpet double-sided tape stick strongly, and when the top cover and this carpet double-sided tape are pulled apart, the top pile (hair feet) may be pulled out. . Also, a large amount of adhesive remains on the carpet floor side.
Oriental rugs made in the Middle East (for example, overlays from Turkish or Iranian hand-woven steps, etc.) are placed directly on the carpet floor, and the color of the Oriental rug dye will change depending on the time, temperature and humidity conditions. May have been transferred to the floor pile. For this reason, in the gaps where the double-sided tape for carpet is not applied, the oriental rug is in direct contact with the pile (hairs) of the carpet floor, which may cause damage due to this dye transfer phenomenon.

  As described above, the conventional construction method has a defect, and hinders the possibility of selling an overlay placed thereon and the possibility of selling a carpet as a flooring material.

(2) When the top cover is a sheet of vinyl chloride resin, a sheet of polyolefin resin, or a simple carpet rug with a waterproof effect:
When pet animals such as indoor dogs are kept indoors on the carpet floor, a cage may be set up as a place to stay. Or a partial space may be used as a play or playground. In some cases, elderly people with dementia who are prone to rough phases live in the carpet floor. In these cases, in order to protect the carpet floor from dirt such as feces, urine, and vomit, a waterproof overlay is placed on the carpet floor. Examples of the waterproof rug include a vinyl chloride resin sheet, a polyolefin resin sheet rug, and a simple carpet rug having a waterproof effect.
When these overlays and the like having a waterproof effect are directly laid on the carpet floor as they are and pet animals or humans walk on them, these overlays are displaced and wrinkles and sagging occur. Pets and humans fall when they are caught in these traps and slacks. Moreover, this occurring situation worsens the aesthetics of the room. For this reason, various construction methods have been devised so far to prevent the overlay placed on the floor from moving and causing wrinkles and sagging.
For example, conventional methods for preventing the occurrence of this shift movement, wrinkles and sagging include the following methods.

◎ A method of bonding the upper floor and the lower carpet floor with adhesive tape.
◎ A method of laying a board on the entire surface under the back of the upper covering.
◎ A method of placing heavy objects on the four corners of these overlays so that they do not move.
◎ A method of securing the corners of these overlays from above so as not to damage the soles of the feet.

  Placing heavy objects in the four corners to keep them from moving is safe and harmless in an easy way. It is safe to keep it from the top as long as it does not come off. There is a risk of injury if the heel is removed. In the method of using an adhesive tape, the adhesive used in the tape used on the back surface of the overlay and the carpet floor surface may be transferred depending on the passage of time and temperature conditions, which may cause harm. In the method of laying and laying a board, a floor board is newly provided at that portion, so that a step between a hard floor surface and a soft floor surface can be formed. Even in the case of a plate that can be moved easily, it takes effort to move. Also, if this is plywood, the woody color may be transferred to the carpet floor if it is unpainted. Alternatively, when the adhesive gas in the plywood diverges, the underlying carpet floor surface may turn yellow.

  As described above, except for the method of placing heavy objects in the four corners so that they do not move, the conventional construction method has defects, and the possibility of selling the overlay on top and the possibility of selling the carpet as flooring Is hindering.

Problems to be solved by the invention

  An overlay placed on a carpet floor laid as a flooring is displaced when a human or animal walks on it, resulting in wrinkles and sagging. People are caught in these traps and slacks, and in the case of humans, there is a risk of falling. In addition, the situation in which this shift motion wrinkle or sagging occurs deteriorates the aesthetics of the room.

  Therefore, this method of laying construction of the overlay of the present invention is a construction method in which even if a human or animal walks on the overlay placed on the carpet floor, the overlay does not move and does not cause wrinkles or sagging.

  The occurrence of wrinkles and sagging of the overlay placed on the carpet floor is caused by repeated load applied when humans and animals walk on the overlay. This is a well-known phenomenon caused by factors such as the movement of the foot) up and down, the movement back and forth, left and right, and the movement added to the inclination of the carpet pile (hairy feet) already generated from the manufacturing stage. The direction in which the overlay moves and moves on the surface is the direction in which the inclination of the carpet pile (hair feet) of the carpet floor already generated from the carpet manufacturing stage is tilted.

  Carpet manufacturers, distributors, contractors, scholars, specialists, etc. have been engaged in the development of construction methods for laying construction that does not cause this phenomenon on the carpet placed on the carpet floor for many years. The final conclusion that can be put to practical use is a method of using a product that prevents this currently on the market. However, all of the construction methods that currently use this product on the market (a product that can prevent the occurrence of wrinkles and sagging of the rug placed on the rug on top of it) are as detailed in the prior art text of this patent application. Have flaws.

If nothing is done, slippage and sagging of the overlay placed on the carpet floor will occur, and if a method that uses a previously devised product that prevents this from being marketed is used, It has some flaws as pointed out and detailed in the prior art section.
Because we have this defect problem, therefore, people who live in buildings with hard flooring (hard flooring such as wooden flooring, stone, and tiles) Those who want to buy a new product hesitate to change the floor of the building to a carpet floor.
Currently, people who already have carpet flooring as a flooring are hesitant to buy a new overlay if they are aware of this problem. In this way, the possibility of selling the overlay and the possibility of selling the carpet as a flooring material are hindered.

  Consumers who live in buildings where the floor of the building has a carpet floor finish, if it is possible to resolve the occurrence of wrinkles and sagging of the overlay placed on the carpet floor laid as flooring without causing defects Can buy any overlay without hesitation. Sellers and contractors can offer consumers a good idea to purchase overlays. Carpet makers can carry out planning and development of overlays that match the carpet floor. In addition, consumers, distributors, contractors, and carpet manufacturers can promote the building floors to be fully carpeted.

Means for solving the problem

According to the first aspect of the present invention, the problem can be solved. This is solved by a special construction method using a nonwoven fabric sheet as a constituent element.

Although the nonwoven fabric sheet which comprises this component is limited to a nonwoven fabric sheet with many fuzz, it is a sheet | seat which exists conventionally. Combining conventional non-woven sheets, we have invented new functions and effects by a method that no one has ever found.

Nonwoven sheet (A) and (A '); The nonwoven sheet of this area | region is a sheet | seat as cocoon cotton stuffed in in the clothing industry, bedding industry, and chair furniture industry.
40 to 300 g per unit square meter of 0.3 to 30 denier polyester fiber, nylon fiber, polypropylene fiber, or other staple fiber (short fiber) 100% by a blending card machine, or a web made of blended cotton of each of the above fibers Make a sheet. It is essential that the web sheet has a lot of fluff, is elastic, has a mixed cotton state that does not have a certain direction, is intertwined, and that the web is not easily separated. Therefore, in order to make it difficult for the staple fibers (short fibers) to be separated from each other, the web may be linked with a resin, or may be a web subjected to thermal bonding treatment by mixing low melting point fibers. The web thickness should be between about 1.5 cm and about 3 cm. Hereinafter, this is referred to as a nonwoven fabric sheet (A).
Then, the nonwoven fabric sheet (A) is processed through an ultrasonic processing (pin sonic) machine, and processed into a nonwoven fabric sheet of a web having an average thickness of about 1 cm with a lot of uneven fuzz with a dotted line pattern. Hereinafter, this is referred to as a nonwoven fabric sheet (A ′).

Non-woven fabric sheet (B): This is a non-slip sheet for an overlay used on a hard floor, and is a needle punched non-woven fabric sheet that is sprayed or impregnated with an adhesive resin to impart adhesiveness. The non-slip nonwoven fabric sheet sprayed or impregnated with an anti-slip adhesive resin is produced by the following method.
It consists of 100% of polyester fiber, nylon fiber, polypropylene fiber, or other staple fiber (short fiber) with a basis weight of 40 to 300 g per square meter by a blended cotton card machine, or a blend of the above fibers. Make a web sheet. Three types of nonwoven fabric manufacturing methods are suitable for consolidating the web from a blended card machine and processing it into a thin nonwoven fabric. The three types of specifications are: (1) Only the web is needle punched from the top and bottom to make a nonwoven fabric with a thickness of about 1 mm to about 10 mm; (2) The web is placed on a spunbond fabric A non-woven fabric having a thickness of about 1 mm to about 10 mm in which the spunbonded fabric and the web are bonded to each other by needle punching only from one side, and (3) a spunbonded fabric or a polypropylene flat yarn fabric, Alternatively, the web is placed on both upper and lower sides of the polyester yarn net cloth and needle punched from above and below to form a nonwoven fabric having a thickness of about 1 mm to about 10 mm consisting of three layers. In each of these processes, the surface of the nonwoven fabric is made to leave a lot of fluff.
And in order to give adhesiveness to a nonwoven fabric sheet, an adhesive is sprayed or impregnated on both surfaces of this nonwoven fabric, and it fixes to the fiber of a nonwoven fabric. For example, an acrylic pressure-sensitive adhesive or a pressure-sensitive adhesive based on acrylic and high styrene is sprayed or impregnated to fix the fibers on the nonwoven fabric. The anti-slip force, when measured with a size of 18 cm × 18 cm of a nonwoven fabric sprayed with an adhesive, has an upper limit of 2.50 [Kgf / 324 square centimeters] at a load of 0.5 kg, a horizontal pulling speed of 150 mm / min, and a lower limit of 0. .20 [Kgf / 324 square centimeters]. If the non-slip force is within the same range in the three types of non-woven fabrics that have been sorted, these are collectively used as a needle punched non-woven fabric sheet with an adhesive. Hereinafter, this is referred to as a nonwoven fabric sheet (B).

The construction method is as follows. If you make a mistake, you will not be able to express its effects.
Decide on an overlay to place on the carpet floor. Next, the nonwoven fabric sheet (A) or (A ′) cut according to the size of the overlay and the nonwoven fabric sheet (B) cut according to the size of the overlay are prepared.
Part 1: Construction procedure using nonwoven sheet (A) and nonwoven sheet (B) is as follows.
A non-woven sheet (A) is laid on the carpet floor, and the non-woven sheet (B) is laid on the carpet sheet just above the non-woven sheet (A). Finally, an overlay is placed on the nonwoven fabric sheet (B).
Part 2: Construction procedure using nonwoven sheet (A ') and nonwoven sheet (B) is as follows.
A non-woven sheet (A ′) is laid on the carpet floor, and the non-woven sheet (B) is laid on top of the non-woven sheet (A ′). Finally, an overlay is placed on the nonwoven fabric sheet (B).
The construction method constructed in the above procedure is a construction method in which two different types of non-woven fabrics are laid according to a predetermined procedure in order to prevent wrinkles and sagging of the overlay placed on the carpet floor.
If the construction is carried out in the above order, the overlay placed will not cause a wrinkle or sagging even if there is a repeated load applied when a human or animal walks on the overlay.

TECHNICAL FIELD OF THE INVENTION

The present invention is an invention of a construction method that has never been considered before, in which two non-woven sheets of different types are stacked and placed on a carpet floor to prevent the occurrence of wrinkles and sagging of the overlay placed thereon. It is.

The [1] component of the present invention and [2] operational effects will be described in detail below.
[1] Constituent elements Each non-woven fabric sheet constituting this constituent element is a non-woven sheet having a lot of fluff, but is a conventional sheet. A combination of these conventional sheets is used, and a new function and effect are invented by a method that no one has ever devised.

Non-woven fabric sheet (A) with many fluffs, or thin nonwoven fabric sheet (A ') with lots of uneven fluff with dotted line pattern through nonwoven fabric sheet (A) through ultrasonic processing (pin sonic) machine, with adhesive A nonwoven fabric sheet (B) is prepared. A nonwoven fabric sheet (A), a nonwoven fabric sheet (A '), and a needle punched nonwoven fabric sheet (B) with an adhesive will be described below.

Description of non-woven sheet (A); 40 to 300 g per unit square meter of 0.3 to 30 denier polyester fiber, nylon fiber, polypropylene fiber, or other staple fiber (short fiber) 100% by a mixed cotton card machine, or A web sheet made of a blend of the fibers is made. It is essential that the web sheet has a lot of fluff, is elastic, has a mixed cotton state that does not have a certain direction, is intertwined, and that the web is not easily separated. Therefore, in order to make it difficult for the staple fibers (short fibers) to be separated from each other, the web may be linked with a resin, or may be a web subjected to thermal bonding treatment by mixing low melting point fibers. The thickness of the web sheet should be about 1.5 cm to about 3 cm. Hereinafter, this is referred to as a nonwoven fabric sheet (A).

Description of nonwoven fabric sheet (A ′); nonwoven fabric sheet (A) is processed through an ultrasonic processing (pin sonic) machine, and a web nonwoven fabric sheet having an average thickness of about 1 cm with a lot of uneven fuzz with a dotted line pattern. And Hereinafter, this is referred to as a nonwoven fabric sheet (A ′).

Description of Non-woven Sheet (B): A non-slip nonwoven resin sheet sprayed or impregnated with an anti-slip adhesive resin is produced by the following method. It consists of 100% of polyester fiber, nylon fiber, polypropylene fiber, or other staple fiber (short fiber) with a basis weight of 40 to 300 g per square meter by a blended cotton card machine, or a blend of the above fibers. Make a web sheet. In order to solidify the web from the mixed carding machine and process it into a thin nonwoven fabric, three types of nonwoven fabric manufacturing methods are suitable. The three types of specifications are: (1) Only the web is needle punched from the top and bottom to make a nonwoven fabric with a thickness of about 1 mm to about 10 mm; (2) The web is placed on a spunbond fabric A non-woven fabric having a thickness of about 1 mm to about 10 mm in which the spunbonded fabric and the web are bonded to each other by needle punching only from one side, and (3) a spunbonded fabric or a polypropylene flat yarn fabric, Alternatively, the web is placed on both upper and lower sides of the polyester yarn net cloth and needle punched from above and below to form a nonwoven fabric having a thickness of about 1 mm to about 10 mm consisting of three layers. In each of these processes, the surface of the nonwoven fabric is made to leave a lot of fluff. And in order to give adhesiveness to a nonwoven fabric sheet, an adhesive is sprayed or impregnated on both surfaces of this nonwoven fabric, and it fixes to the fiber of a nonwoven fabric. For example, an acrylic pressure-sensitive adhesive or a pressure-sensitive adhesive based on acrylic and high styrene is sprayed or impregnated to fix the fibers on the nonwoven fabric. The anti-slip force, when measured with a size of 18 cm × 18 cm of a nonwoven fabric sprayed with an adhesive, has an upper limit of 2.50 [Kgf / 324 square centimeters] at a load of 0.5 kg, a horizontal pulling speed of 150 mm / min, and a lower limit of 0. .20 [Kgf / 324 square centimeters]. If the non-slip force is within the same range in the three types of non-woven fabrics that have been sorted, these are collectively used as a needle punched non-woven fabric sheet with an adhesive. Hereinafter, this is referred to as a nonwoven fabric sheet (B).

[2] Operational Effects The operational effects of the invention can be exhibited by a method of using the nonwoven fabric sheet (A) or (A ′) and the nonwoven fabric sheet (B) simultaneously and complementarily. This will be described in detail by dividing into [materials used in the construction method], [laying construction method] and [principle of action and effect].

[Materials used in construction methods]
Nonwoven fabric sheet (A) or (A ′): Unwoven sheet (A) made of web-like nonwoven sheet with a lot of fluff, or irregularities with a dotted line pattern made by passing this nonwoven sheet (A) through an ultrasonic processing (pin sonic) machine A thin nonwoven fabric sheet with many fluffs is a nonwoven fabric sheet (A ′).
Non-woven fabric sheet (B); Non-woven fabric sheet (B) is an adhesive non-woven fabric sheet with fluff.

[Laying construction method]
The construction method is performed in the following order.
First, the non-woven fabric sheet (A) or (A ′) cut according to the size of the overlay to be placed on the carpet floor is laid on the carpet floor laid as a flooring material. Next, the non-woven fabric sheet (B) cut according to the size of the overlaid material to be placed is placed on the non-woven fabric sheet (A) or (A ′) placed thereon. Finally, an overlay is placed on the nonwoven fabric sheet (B). This is a construction method in which two types of non-woven fabrics are laid according to the procedure determined above.

[Principle of action and effect]
There are three types of carpets laid as a flooring material, depending on the type of carpet pile. They are cut pile carpet, loop pile carpet, loop and cut pile carpet. The non-woven sheet (A) or (A ′) having a large amount of fluff is entangled with the fluff on the cut surface of the pile (fluff) on the cut pile carpet floor. On the loop pile carpet floor, it entangles with the fluff on the side of the pile. On the loop and cut pile carpet floor, the cut surface of the pile (fleece) and the fluff on the side are entangled. By tangling, the nonwoven fabric sheet (A) or (A ′) sticks to the carpet floor surface laid as a flooring material and does not move.

  As described above, the lower surface of the nonwoven fabric sheet (A) or (A ′) sticks and does not move on the carpet floor laid as a flooring material. And the upper surface of this nonwoven fabric sheet (A) or (A ') remains as a nonwoven fabric sheet with many fuzz. An adhesive non-woven sheet (B) having fluff of the same size is placed on the remaining surface. When these surfaces are combined, the fluffy, non-woven fabric sheet (B) is intertwined with the surface layer surface of the non-woven fabric sheet (A) or (A ′) with many fluffs. Since the non-woven fabric sheet (B) is sticky, the surfaces of the two types of non-woven fabric sheets that are entangled with each other do not shift and come into close contact with each other. Thus, the lower surface of the non-woven fabric sheet (B) is entangled with the non-woven fabric sheet (A) or (A ′), and the upper surface of the non-woven fabric sheet (B) is fuzzy and sticky non-woven fabric sheet (B ) Remains as.

  The remaining upper surface of the adhesive non-woven sheet (B) prevents the movement of the overlay due to its adhesiveness. It plays the role which prevents generation | occurrence | production of the shift motion wrinkle and sagging of the overlay placed on the nonwoven fabric sheet (B). This is the principle of action and effect.

This non-woven sheet (A) or non-woven sheet in the region of (A ') is a sheet as cotton that has been stuffed in the garment industry, bedding industry, and chair furniture industry. Even if the nonwoven fabric sheet (A) or (A ′) contains the movement and properties of the surface where the fluff surface on one side and the carpet pile (hair foot) surface of the carpet floor are intertwined, the remaining one side is It remains as it is, but in this state it does not get tangled on the back of the overlay. Therefore, this nonwoven fabric sheet (A) or (A ′) alone cannot prevent the occurrence of wrinkles and sagging of the overlay.

The fluffy and sticky non-woven sheet (B) alone is a non-slip sheet for a hard floor in the interior goods industry. The non-woven sheet (B) is a non-slip force value that does not stick to the carpet and piles on the carpet and the carpet floor. Construction does not prevent slippage or sagging of the overlay placed on the carpet floor.

In order to measure the specific configuration of the technology in the examples and the actions and effects in the examples, products were actually made and the effects were measured. The measurement method was as follows.
The following carpet materials were used for the carpet floor.
In 100% wool tufted carpet, cut pile carpet pile length 7 mm, its structure is 1/10 gauge, 9.5 stitches, to measure its effect on the product of the weight 1 m ² per about 1.8 kg.
The carpet floor laying method used as a base was a felt gripper method using a urethane chip sheet material.

  There are two main methods of laying carpets as flooring materials: the solid construction method and the felt gripper method. And the degree which produces the slipping movement, wrinkles and sagging of the overlay placed on the top differs depending on the construction method. The laying method for needle punch carpets and tile carpets is usually a solid method in which an adhesive or an adhesive is applied to the floor surface and the carpet is placed on the upper surface. The wide carpet laying method is partly covered with an adhesive or adhesive on the floor surface, and the wide carpet is directly pasted on the top surface. A felt gripper construction method in which a fiber felt sheet material and a urethane chip sheet material hardened to a thickness of 8 mm are first laid on the floor, and then a wide carpet is placed on the upper surface of the felt gripper method. The movement of the overlay placed on the carpet floor and the occurrence of wrinkles and sagging are caused by the movement of the carpet pile on the carpet floor below when the human or animal walks on the overlay. This is a well-known phenomenon caused by factors such as forward / backward / left / right movement and pile inclination already generated from the manufacturing stage. On carpet floors that have been solid-finished with needle punched carpets, tile carpets and wide carpets that have no cushioning on the back side, only the movement of the carpet piles (bristle feet) will cause the slippage of the overlays placed above It is a factor that affects the generation of movement, wrinkles and sagging. Needle punch carpets, tile carpets, wide carpets, carpet floors with cushions on the back, and carpet floors laid by felt gripper construction of wide carpets, slippage movement, wrinkles and sagging occur It affects not only the movement of the carpet pile (hair feet), but also the elasticity of the cushion material attached to the base, and the fiber felt sheet material and urethane chip sheet material laid on the base by the felt gripper method. Sexual movement also adds to the factors that act. Therefore, in this effect measurement, the method of laying the carpet as a flooring is measured under the felt gripper method using a urethane chip sheet material.

  A model product of a nonwoven fabric sheet (A ') having an average of about 1 cm in thickness with a large number of fluffs with irregularities, in which a nonwoven fabric sheet (A) with a lot of fluff is passed through an ultrasonic processing (pin sonic) machine and is dotted. Made with.

A web made of 100% polyester staple fiber (short fiber) with a basis weight of 17 denier per square meter is produced by a blended card machine. In this polyester fiber, 10% polyester low melting point fiber (fiber) is mixed. The web is processed with a thermal bond machine to produce a nonwoven sheet (A) having a thickness of about 3 cm to which the web is fixed. The manufactured nonwoven fabric sheet (A) having a thickness of about 3 cm is processed into a nonwoven fabric sheet with an average thickness of about 1 cm with a dotted line pattern through an ultrasonic processing (pin sonic) machine. This is because the nonwoven fabric sheet of the web with the original thickness is pulled to the fused portion, and the overall thickness is reduced by the web being ultrasonically processed (pin sonic) machine. getting thin. The model product was a 5cm pinpoint diamond pattern. The non-woven sheet of the web becomes thin with an average thickness of about 1 cm, and the unpressed portion remains as the original lump of the web. And this lump part retains the properties of the original web. The web lump has fluff, elasticity, and the mixed cotton state does not have a certain direction and is intertwined.
This is a nonwoven fabric sheet (A ').

  A model product of a non-slip nonwoven fabric sheet (B) having a fluff sprayed with an adhesive resin having an anti-slip effect was prepared by the following method.

  A web of polyester fiber with a basis weight of 150 g per square meter from a blended card machine is placed on a polyester spunbond fabric with a basis weight of 20 g per square meter, and needle punching is applied only from one side to the spunbond fabric. A non-woven fabric having a thickness of about 1.5 mm is formed by laminating a web of polyester fibers. And in order to give adhesiveness, the adhesive based on acrylic and high styrene is sprayed on both surfaces of this nonwoven fabric, and it fixes to this nonwoven fabric. The anti-slip force was 1.13 [Kgf / 324 square centimeters] at a load of 0.5 kg and a horizontal pulling speed of 150 mm / min when measured with a size of 18 cm × 18 cm of the nonwoven fabric sprayed with this adhesive.

The following two types of overlays were measured with a Persian carpet of oriental rug and a vinyl chloride resin sheet.
Persian carpets, made in Pakistan,
Hand-woven single knot,
Excluding size 30cm x 32cm tufts,
100% wool, 100% cotton yarn,
Pile length 7mm,
Weight 224g / sheet Vinyl chloride resin sheet; made in Japan,
Size 30cm × 30cm,
Thickness 0.03mm,
Weight 24g / sheet

  An overlay was placed on the carpet floor, and a flat surface having a size of 8 cm wide × 25 cm long was dropped 100 times / min on the carpet with a drop impact receiving weight of 80 kg.

  The results of experiments with the specifications of the construction method for laying construction of the present invention are the following numerical values. The measurement conditions were the above carpet material, and the carpet floor was laid by a gripper method using 8 mm thick urethane chip felt material, and the nonwoven fabric sheet (A ′) was placed on the carpet floor. The nonwoven fabric sheet (B) was placed on top, and the overlay was placed on the nonwoven fabric sheet (B).

  Actual measurement behavior of overlay (measured average value of 4 tests): Persian carpet 0 cm, vinyl chloride resin sheet 0 cm.

  The experiment has the following numerical values in a specification in which the overlay is placed directly on the carpet floor without using the method of the present invention. The measurement conditions were as follows. The carpet material was used, and the carpet floor was laid by a gripper method using a urethane chip felt material having a thickness of 8 mm, and the overlay was placed directly on the carpet floor.

  Actual measurement behavior of the overlay (test average of 4 measurements): Persian carpet 8 cm, vinyl chloride resin sheet 20 cm.

  Regarding the occurrence of slippage movement and wrinkles and sagging of the overlay placed on the carpet floor, the measured behavior result of the overlay tested with the specifications of the construction method of the laying construction of the present invention is 0 cm. And since the nonwoven fabric sheet (A ') placed on the carpet floor is not attached with an adhesive, there is no harm to the carpet floor. The amount of adhesive applied to the nonwoven fabric sheet (B) does not stick to the base of the overlay pile (hairs) on the back of the overlay, and when the overlay is separated from the nonwoven fabric, the overlay Never pull out the pile.

  Conventional nonwoven fabric sheets (A), nonwoven fabric sheets (A '), and nonwoven fabric sheets (B) that are conventionally known nonwoven fabric sheets used for the constituent elements of the present invention are not limited to the examples described above.

  All of the construction methods that currently use this product on the market (a product that can prevent the occurrence of wrinkles and sagging of the rug placed on the rug on top) are as pointed out and detailed in the prior art section of this patent application. I have a flawed problem. Because of this deficiency, therefore, people who currently live in buildings with hard flooring (hard floors such as wooden flooring, stone, tiles, etc.), who own overlaying and newly purchased overlaying The person who wants to do so hesitates to change the interior of the building floor to a carpet floor in consideration of the trouble that is expected to occur. At present, people who have already used the flooring of the building as a flooring material to carry carpet flooring have this problem, so hesitate to purchase a new overlay. In this way, the marketability of the overlay and the marketability of the carpet as a flooring material are hindered.

  Consumers who live in buildings where the floor of the building has a carpet floor finish, if it is possible to stop the occurrence of wrinkles and sagging of the overlay placed on the carpet floor laid as flooring without any defect Can buy any overlay without hesitation. Sellers and contractors can offer consumers a good idea to purchase overlays. Carpet makers can carry out planning and development of overlays that match the carpet floor. In addition, consumers, distributors, contractors, and carpet manufacturers can promote the building floors to be fully carpeted.
