Description

  The present invention relates to a bedding side cloth and a bedding product in which batting is difficult to blow out and stuffiness is unlikely to occur.

As a characteristic required for the bedding side ground, first, since the inside pad is used by filling the inside pad, it is necessary to prevent the filling from blowing out. For this purpose, so-called crushing is performed, in which the weaving density is increased or the space between the heating rollers is pressed through the fabric.
However, if the weave density is increased too much, the air permeability is lowered, and there is a problem that stuffiness occurs during use. Thus, it has been difficult to achieve both prevention of blowing of batting and appropriate air permeability.

  It is known that side fabrics such as bedding and stuffed toys are made of fibers having relatively small fineness (see, for example, Patent Document 1 and Patent Document 2).

JP-A-3-261696 Japanese Utility Model Publication No. 4-103195

  The present invention has been made in view of the above background, and an object thereof is to provide a bedding side cloth and a bedding product in which batting is difficult to blow out and stuffiness is unlikely to occur.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors obtained a woven fabric using filament yarn having a single fiber diameter of 10 to 1,500 nm and a very small single fiber diameter as a bedding side land, Because the friction coefficient of the filament yarn is high, the friction between the yarn constituting the fabric and the yarn becomes large, and even when an external force is applied, it is difficult to deform the texture. As a result, while maintaining a certain degree of air permeability, The present inventors have found that the blow-out of batting can be prevented and completed the present invention by further intensive studies.

Thus, according to the present invention, there is provided a “bedding side ground characterized in that it is composed of a woven fabric containing filament yarn A having a single fiber diameter of 10 to 1,500 nm”.
At that time, the filament yarn A is preferably at least one selected from the group consisting of polyester, nylon, and acrylic. The filament yarn A preferably has 500 or more filaments. The woven fabric preferably includes filament yarn B having a single fiber diameter larger than 1,500 nm as another filament yarn. The filament yarn B is preferably at least one selected from the group consisting of polyester, nylon, acrylic, cotton, and silk. Further, the filament number of the filament yarn B is preferably in the range of 1 to 500. Moreover, it is preferable that the cover factor (CF) of the textile fabric defined below is in the range of 2,000 to 4,500.

CF = (DWp / 1.1) ^1/2 × MWp + (DWf / 1.1) ^1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).

Moreover, in the bedding side place of this invention, it is preferable that the structure | tissue of a textile fabric is a twill structure. Moreover, it is preferable that the air permeability measured using the JIS L1096A method fragile type tester is in the range of ^{2 to 20} cm ³ / cm ² · sec.
Furthermore, the filament yarn A is exposed more than the filament yarn B on the inner side surface of the bedding side ground, and the filament yarn B is exposed more than the filament yarn A on the outside air side surface of the bedding side ground. It is preferable.

  Moreover, according to this invention, the bedding goods which use the said bedding side place are provided.

  According to the present invention, it is possible to obtain a bedding side cloth and a bedding product in which batting is difficult to blow out and stuffiness is unlikely to occur.

Hereinafter, embodiments of the present invention will be described in detail.
The bedding side ground of the present invention is composed of a woven fabric including filament yarn A having a single fiber diameter of 10 to 1,500 nm.

  Here, in the filament yarn A (hereinafter also referred to as “nanofiber”), the single fiber diameter (single fiber diameter) is 10 to 1,500 nm (preferably 250 to 800 nm, particularly preferably 510). It is important to be within the range of ˜800 nm. When the single fiber diameter is smaller than 10 nm, the fiber strength is lowered, which is not practically preferable. On the contrary, when the single fiber diameter is larger than 1,500 nm, the friction between the yarn constituting the woven fabric and the yarn becomes small, and the texture is easily deformed when an external force is applied. As a result, the batting is easily blown out. Therefore, it is not preferable. Here, when the cross-sectional shape of the single fiber is an atypical cross section other than the round cross section, the diameter of the circumscribed circle is defined as the single fiber diameter. The single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope.

  In the filament yarn A, the number of filaments is not particularly limited, but is 500 or more (more preferably 2,000 to 50,000) in order to obtain a slipperiness and soft texture between the yarns constituting the woven fabric. Preferably there is. The total fineness of the filament yarn A (the product of the single fiber fineness and the number of filaments) is preferably in the range of 50 to 800 dtex.

  The fiber form of the filament yarn A is not particularly limited, but is preferably a long fiber (multifilament yarn). The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. In addition, normal air processing and false twist crimping may be applied. Two or more types of filament yarn A may be used in combination.

  The type of polymer forming the filament yarn A is not particularly limited, and any polymer may be used, but polyester, nylon, or acrylic is preferable in terms of fiber strength. Among these, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyester obtained by copolymerizing the third component, and the like are preferably exemplified. Such polyester may be material recycled or chemically recycled polyester. Further, polyesters obtained by using a catalyst containing a specific phosphorus compound and a titanium compound, such as those described in JP-A-2004-270097 and JP-A-2004-212268, polylactic acid, and stereocomplex Polylactic acid may be used. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent, as necessary, within a range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.

  The fabric constituting the bedding side fabric of the present invention may be composed only of the filament yarn A. In this case, both sides of the fabric have poor surface slippage (high friction coefficient) and the bedding side fabric. Therefore, it is preferable that the filament contains a filament B having a single fiber diameter larger than 1,500 nm as the other filament.

At that time, the filament yarn B preferably has a single fiber diameter larger than 1,500 nm (preferably 2 to 33 μm). When the single fiber diameter is 1,500 nm (1.5 μm) or less, both sides of the fabric have poor surface slippage (high friction coefficient), and the handling property of the bedding side may be deteriorated. Here, when the cross-sectional shape of the single fiber is an atypical cross section other than the round cross section, the diameter of the circumscribed circle is defined as the single fiber diameter. In addition, the single fiber diameter can be measured by photographing the cross section of the fiber with a transmission A over-type electron microscope, as described above.
In the filament yarn B, the number of filaments is not particularly limited, but is preferably in the range of 1 to 300. The fiber form of the filament yarn B is not particularly limited and may be a spun yarn, but it is preferable to use a long fiber (multifilament yarn), a polyurethane fiber, or both. The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. Further, normal air processing and false twist crimping may be applied, and the filament yarn B may be of two or more types.

  The type of polymer forming the filament yarn B is not particularly limited and may be any polymer, but polyester, nylon, acrylic, cotton, or silk is preferable in terms of fiber strength. Of these, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyester obtained by copolymerization of the third component, polyether ester, urethane and the like are preferably exemplified. Such polyester may be material recycled or chemically recycled polyester. Furthermore, polyester, polylactic acid, and stereocomplex poly obtained by using a catalyst containing a specific phosphorus compound and a titanium compound as described in JP-A-2004-270097 and JP-A-2004-212268. Lactic acid may be used, but an elastic resin such as polyetherester or polyurethane is preferable when the anti-slip effect is further pursued. In the polymer, within the range not impairing the object of the present invention, if necessary, a micropore forming agent, a cationic dye dyeing agent, a coloring inhibitor, a heat stabilizer, a fluorescent whitening agent, a matting agent, One or two or more colorants, hygroscopic agents, and inorganic fine particles may be contained.

  In the filament yarn A and filament yarn B, the fibers preferably have a plurality of combinations. For example, an elastic fiber yarn made of polyurethane fiber or polyether ester fiber, and a polyester fiber yarn or nylon fiber yarn. And composite yarn in which polyester yarn or nylon fiber yarn is covered around an elastic fiber yarn made of polyurethane fiber or polyetherester fiber, etc. , A composite yarn with a spun yarn, or this may be woven.

  Examples of the fabric structure of the woven fabric include a plain structure, a twill weave, a satin weave, and the like, a change structure, a single double structure such as a vertical double weave, a horizontal double weave, and a vertical velvet. It is not limited. The number of layers may be a single layer or a multilayer of two or more layers. Among them, a twill structure is most preferable in order to obtain a fabric having a certain density.

  Here, when the woven fabric is constituted by using the filament yarn A and the filament yarn B, the surface on which the filament yarn A is exposed is used on the inside, and the surface on which the filament yarn B is exposed on the outside side is used. The surface on the outside air side of the ground is preferable to improve the handling property.

The bedding side place of the present invention can be manufactured, for example, by the following manufacturing method.
First, a sea-island composite fiber (filament yarn A fiber) formed of a sea component and an island component made of polyester and having a diameter of 10 to 1,500 nm is prepared. As such a sea-island type composite fiber, a sea-island type composite fiber multifilament (the number of islands: 100 to 1,500) disclosed in JP-A-2007-2364 is preferably used.

  That is, as the sea component polymer, polyester, polyamide, polystyrene, polyethylene and the like having good fiber forming properties are preferable. For example, as an easily soluble polymer in an alkaline aqueous solution, polylactic acid, an ultra-high molecular weight polyalkylene oxide condensation polymer, a polyethylene glycol compound copolymer polyester, a copolymer polyester of polyethylene glycol compound and 5-sodium sulfonic acid isophthalic acid may be used. Is preferred. Among them, polyethylene terephthalate having an intrinsic viscosity of 0.4 to 0.6 obtained by copolymerizing 6 to 12 mol% of 5-sodium sulfoisophthalic acid and 3 to 10% by weight of polyethylene glycol having a molecular weight of 4,000 to 12,000. A copolyester is preferred.

  On the other hand, the island component polymer is preferably a polyester such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, or polyester obtained by copolymerizing a third component, which has good fiber-forming properties. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent, as necessary, within a range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.

  The sea-island composite fiber composed of the sea component polymer and the island component polymer preferably has a melt viscosity of the sea component at the time of melt spinning larger than the melt viscosity of the island component polymer. The diameter of the island component needs to be in the range of 10 to 1,500 nm. At this time, if the shape of the island component is not a perfect circle, the diameter of the circumscribed circle is obtained. In the sea-island composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90.

  Such a sea-island type composite fiber multifilament yarn can be easily manufactured, for example, by the following method. That is, melt spinning is performed using the sea component polymer and the island component polymer. As the spinneret used for melt spinning, any one such as a hollow pin group for forming an island component or a group having a fine hole group can be used. The discharged sea-island type cross-section composite fiber multifilament yarn is solidified by cooling air, and is preferably wound after being melt spun at 4,00-60,00 m / min. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage properties through a separate drawing process, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn. Any of the methods of winding after passing through may be used. In such a sea-island type composite fiber multifilament yarn, the single yarn fiber fineness, the number of filaments, and the total fineness are within the range of the single yarn fiber fineness of 0.5 to 10.0 dtex, the number of filaments of 5 to 75, and the total fineness of 30 to 170 dtex, respectively. It is preferable that

  On the other hand, if necessary, a filament B having a single fiber fineness of 0.1 dtex or more (preferably 0.1 to 0.9 dtex) is prepared. In order to make the single fiber diameter of the filament yarn B in the finally obtained fabric larger than 1,500 nm, it is preferable that the single fiber fineness is within the above range.

  In the filament yarn B, the number of filaments and the total fineness are preferably in the range of 1 to 300 filaments (more preferably 100 to 300) and the total fineness of 10 to 800 dtex. Further, the filament yarn may be a high shrinkage polyester having a boiling water shrinkage of 10% or more (more preferably 20 to 40%) or an elastic yarn (polyurethane elastic yarn or polyetherester elastic yarn). .

  Next, a woven fabric is woven by a conventional method using the sea-island composite fiber multifilament yarn and, if necessary, the filament yarn B. At that time, the sea-island type composite fiber filament yarn and the filament yarn B may be contained in the woven or knitted fabric as a mixed yarn, but the filament yarn A and the filament B are interwoven to form a woven fabric. It is preferable to do. The total fineness ratio between the sea-island type composite fiber filament yarn and the filament yarn B is preferably in the range of 90:10 to 20:80.

  Next, the woven fabric (fabric) is subjected to an alkaline aqueous solution treatment, and the sea component of the sea-island type composite fiber is dissolved and removed with an alkaline aqueous solution, whereby the sea-island type composite fiber filament yarn has a single fiber diameter of 10 to 1,500 nm. By using the filament yarn A, the bedding side fabric of the present invention is obtained. At that time, the alkaline aqueous solution treatment may be performed at a temperature of 55 to 65 ° C. using a 3 to 4% NaOH aqueous solution.

  Further, the fabric may be dyed before and / or after dissolution removal with the alkaline aqueous solution. You may give a calendar process (heat-pressing process) and an embossing. Furthermore, conventional brushing processing, water repellent processing, and various functions that provide functions such as ultraviolet ray shielding or antistatic agents, antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, negative ion generators, etc. Processing may be additionally applied.

  In such a woven fabric, the cover factor (CF) of the woven fabric is preferably in the range of 2,000 to 4,500. More preferably, it is in the range of 2,000 to 3,500. If the cover factor is less than 2,000, the filling may be blown out. On the other hand, if the cover factor is larger than 4,500, the air permeability is reduced, and there is a risk of stuffiness.

CF = (DWp / 1.1) ^1/2 × MWp + (DWf / 1.1) ^1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).

In addition, since the bedding side fabric is preferably a soft and draped fabric, the fabric weight is within the range of 50 to 200 g / m ² (more preferably 80 to 120 g / m ² ). Is preferred. When the basis weight is less than 50 g / m ² , the paper-like texture is slightly formed and the filling may be easily blown out. On the other hand, when the basis weight is larger than 200 g / m ² , not only it becomes hard, but it may become too heavy as a bedding.

In the bedding side land of the present invention, the air permeability measured using a JIS L1096A method Frazier type tester is ^{2 to 20} cm ³ / cm ² · second (more preferably ³ to 15 cm ³ / cm ² · second). It is preferable to be within the range. If the air permeability is less than ² cm ³ / cm ² · sec, stuffiness may occur. On the contrary, if the air permeability is higher than 20 cm ³ / cm ² · sec, there is a possibility that the batting is blown out.

  Next, the bedding side fabric is sewn by a conventional method using the woven fabric alone or in combination with other fabrics as necessary. At that time, the bedding side fabric may be constituted only by the woven fabric, but it may have a multilayer structure with a normal polyester woven or knitted fabric, for example.

  Since the filament yarn A (nanofiber) is contained in the fabric constituting the bedding side ground in the bedding side land thus obtained, the contact area between the yarn forming the fabric and the yarn increases, so that the external force Even if it is applied, the texture is difficult to deform, and as a result, the air permeability is stable (that is, there is not much stuffiness) and the batting is difficult to blow out.

Next, the bedding of the present invention will be described.
The bedding product according to the present invention is a bedding product using the above-mentioned bedding side land. Since such a bedding product uses the above-mentioned bedding side place, it is difficult for the batting to blow out and the stuffiness (feeling of stuffiness) hardly occurs during use. Such bedding includes futons, pillows, sofas and the like. Further, the batting is not limited to, for example, stuffed cotton of natural fibers or synthetic fibers, and may be wool, feathers or the like.

  Next, although the Example and comparative example of this invention are explained in full detail, this invention is not limited by these. In addition, each measurement item in an Example was measured with the following method.

<Melt viscosity>
The polymer after the drying treatment is set in an orifice set to a ruder melting temperature at the time of spinning and melted and held for 5 minutes, and then extruded by applying a load of several levels, and the shear rate and melt viscosity at that time are plotted. By gently connecting the plots, a shear rate-melt viscosity curve is created, and the melt viscosity when the shear rate is 1,000 seconds ⁻¹ is observed.

<Dissolution rate>
The yarn is wound at a spinning speed of 1,000 to 2,000 m / min with a base of 0.3φ-0.6L × 24H for each of the sea and island components, and the residual elongation is in the range of 30 to 60%. To produce a 84 dtex / 24 fil multifilament. The weight loss rate was calculated from the dissolution time and the dissolution amount at a bath ratio of 100 at a temperature at which the solvent was dissolved in each solvent.

<Cover factor (CF)>
The cover factor (CF) was calculated by the following formula.
CF = (DWp / 1.1) ^1/2 × MWp + (DWf / 1.1) ^1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).

<Air permeability>
