Description

  TECHNICAL FIELD The present invention relates to a fabric in which a skin side fabric and a back fabric are knitted with raw yarns having different single yarn finenesses, and more particularly to a wetting prevention fabric, an underwear fabric, and an undergarment.

  In general, women are known to have mild “urine leakage” in their 30s and beyond, due to the burden on the body at birth and changes in hormonal balance due to aging. It is not well recognized that there is “urine leakage”. For this reason, there are many other cases where there are many middle-aged men who are unable to consult with others and suffer from mild “urine leakage”.

  Patent Document 1 proposes a urine leakage countermeasure fabric characterized in that a front fabric, a water retention layer, a water absorption diffusion layer, and a waterproof fabric are provided in this order.

  Patent Document 2 discloses a special fabric made of a pile fabric as a special fabric that is excellent in water absorption and has very little rewetting, and 50% or more of the fibers constituting the ground structure are water absorbent fibers, and A special fabric has been proposed in which 50% or more of the fibers constituting the pile are composed of hydrophobic fibers.

JP-A-2005-111181 JP 07-324250 A

  However, the urine leakage countermeasure fabric described in Patent Document 1 is a thick fabric that has a water retention layer and is used for underwear such as adult diapers and diapers with a diaper function. However, it has been difficult to apply to an underwear that can be easily worn without being noticed by surrounding people and without a sense of resistance.

  The special fabric described in Patent Document 2 is mainly used for towels, handkerchiefs, bathrobes, pillow cases, etc., and the single yarn fineness of the water-absorbing fibers constituting the ground tissue is large and relatively thick. For this reason, there is a problem that comfort such as skin feel is not preferable, and quick-drying is insufficient, so that it is not suitable for underwear worn during the day.

  In addition to the “urine leakage” viewpoint, sweat pads etc. are often attached to the inside of clothes to avoid exudation of body fluids such as sweating of wrinkles. Since the multi-layer structure is adopted, it becomes thick, and when used as a fabric touching the skin, there is room for further improvement from the viewpoint of wearing feeling.

  In view of the above-mentioned problems, the object of the present invention is to be used by ordinary people without a sense of resistance. The point is to provide underwear.

  In order to achieve the above-mentioned object, the first feature of the anti-wetting fabric according to the present invention is that the skin side fabric and the back fabric are single yarn fineness as described in claim 1 of the claims. Fabrics knitted with different yarns, and the skin side fabric is knitted with a hydrophobic yarn having a single yarn fineness larger than the single yarn fineness of the raw yarn knitting the backside fabric and its surface is It is in the point which has been brushed.

  According to the above-described configuration, the back side ground structure is knitted with a raw yarn smaller than the single yarn fineness of the raw yarn knitting the skin side ground structure, so that a relatively thin and dense ground structure can be realized. Moisture is quickly absorbed by the good capillary phenomenon due to the dense ground structure and diffused in the surface direction of the fabric. Further, the skin side ground texture is knitted with a hydrophobic raw yarn having a single yarn fineness larger than the single yarn fineness of the raw yarn knitting the back side ground texture, and the surface thereof is raised, so that it is formed by raising treatment. A gap is formed between the ground tissue and the skin surface by the loop, so that wetting back to the skin surface due to moisture infiltrated from the skin side tissue to the back side tissue is effectively suppressed. And since the loop is made of raw yarn having a single yarn fineness larger than that of the back side fabric, it has moderate elasticity and good comfort while maintaining a space formed between the ground tissue and the skin surface. Can be secured. Accordingly, it is possible to effectively suppress the rewetting to the skin due to moisture infiltrated into the fabric from the skin side.

  In the second characteristic configuration, as described in the second aspect, in addition to the first characteristic configuration described above, the raw yarn for knitting the skin side fabric has a single yarn fineness of 3.0 dtex to 7. It is in the range of 0 dtex, and the number of filaments is a long fiber in the range of 12 to 48. By using the raw yarn in this range, a loop is formed between the ground structure and the skin surface. The space is reliably maintained, and good touch can be secured while preventing rewetting.

  In the third characteristic configuration, as described in claim 3, in addition to the first or second characteristic configuration described above, the yarn for knitting the back side ground structure has a single yarn fineness of 0.3 dtex. It is in the range of 3.5 decitex, and is a hydrophobic long fiber with the number of filaments ranging from 12 to 144.

  Since the hydrophobic yarn is used as the yarn for knitting the back side fabric, the capillaries of the back side fabric where the moisture taken in from the skin side fabric is small and the fineness of the single yarn is not retained. Because the phenomenon quickly infiltrates the surroundings, the infiltrated water is quickly evaporated from the back side tissue while preventing the skin from getting wet back.

  In addition to any one of the first to third feature configurations described above, the fourth feature configuration is the base yarn for knitting the skin side fabric and the back fabric. These synthetic fibers can be selected from polyester, nylon, and polypropylene, and can provide a skin-wearing fabric that does not wet back and has a good touch.

  The skin-wearing fabric according to the present invention has any one of the first to fourth characteristic configurations described above on at least a part of the back side of the front fabric knitted with water-absorbing raw yarn as described in claim 5. It is in the point where the prepared wetting prevention cloth is superimposed.

  According to the above-described configuration, the above-mentioned anti-wetting fabric is disposed on at least a part of the urine leaking part, the sweating part, etc. on the side in contact with the skin, so that the skin wearing is light and comfortable as a whole. Since the fabric can be obtained and the thin anti-wetting fabric is superimposed on the back side of the front fabric, the fabric can be easily worn without being noticed by surrounding people and without feeling of resistance.

  As described in claim 6, the second characteristic configuration is that, in addition to the first characteristic configuration described above, the surface of the surface fabric is subjected to water repellent treatment, and is relatively free from anti-wetting back fabric. Even when a large amount of water is infiltrated, the inconvenience of bleeding into outerwear such as pants and shirts is eliminated.

  In addition to the first or second characteristic configuration described above, the third characteristic configuration is knitted with water-absorbing raw yarn between the front fabric and the anti-wetting back fabric. The intermediate fabric is superimposed, and at least the skin-side surface of the intermediate fabric is water-repellent, and even if a relatively large amount of moisture infiltrates into the anti-wetting fabric, the skin-side surface is Moisture does not infiltrate the water repellent intermediate fabric.

  The characteristic configuration of the undergarment according to the present invention is that, as described in claim 8, the underwear fabric according to any one of the first to third aspects described above is sewn in part. It can be preferably applied to the center part of the front body, the heel part of the shirt, and the like.

  As described above, according to the present invention, an anti-wetting anti-wetting fabric, a skin-wearing fabric, and an undergarment that can be used by ordinary people without resistance and that is thin and excellent in quick-drying, such as a skin feel. Can now be offered.

(A) is explanatory drawing of the underwear by which the pad for sweat removal using the wetting prevention fabric by this invention was sewed

Hereinafter, the anti-wetting fabric, the underwear fabric, and the underwear according to the present invention will be described.
As shown in FIG. 1 (a), the anti-wetting back fabric 1 according to the present invention includes two ground tissues, a skin-side texture 2 and a back-side texture 3, and the skin-side texture 2 and the back-side texture 3 respectively. The skin side fabric 2 is knitted with a hydrophobic yarn having a single yarn fineness larger than the single yarn fineness of the raw yarn knitting the back side fabric 3, and is knitted on the skin side after knitting. The ground tissue 2 is raised by a raising machine to form a loop 2a made of the drawn raw yarn.

  As the raw yarn for knitting the back side fabric 3, the single yarn fineness is 0.3T (unit "T" indicates decitex) to 3.5T, and the number of filaments is 12F (unit "F" is the number of filaments). Long fibers in the range from 144F to 144F can be used. It is more preferable to use long fibers having a single yarn fineness of 0.5T to 3.0T and a filament number of 12F to 48F. This is because, as will be described later, a good moisture diffusibility can be secured and a good texture can be obtained.

  In addition, as the raw yarn for knitting the skin side fabric 2, long fibers having a single yarn fineness of 3.0T to 7.0T and a filament number of 12F to 48F can be used. It is more preferable to use a long fiber having a single yarn fineness of 4.5T to 6.5T and a filament number in the range of 12F to 36F.

  If the single yarn fineness is smaller than 3.5 T, the strength of the filament is reduced, so that there is a possibility that the filament may be cut during raising, and in that case, pain will be felt when touching the skin. Even if a loop-like raising is formed without being cut, an appropriate elastic force is not generated, so that a good space is not formed between the skin and the feeling of rewetting cannot be prevented or the drying property is lowered. .

  When the single yarn fineness is thicker than 7.0 T, not only does the inconvenience that the raising cloth is not caught by the filament and the raising property is inferior, but the filament becomes hard and the texture of the fabric is hard, and a good wearing feeling is obtained. Absent. Furthermore, when it becomes too thick, a capillary phenomenon will fall and the water absorption from skin, the diffusibility of the water | moisture content which absorbed water, and drying property will also fall. Therefore, it is necessary for each raw yarn to use long fibers in the above-described range.

  When long fibers in the above-described range are used for the skin side fabric 2 and the back fabric 3, the skin side fabric 2 has a single yarn fineness larger than the single yarn fineness of the raw yarn knitting the back fabric 3. The raw yarn is selected. In the case of a medical fabric or the like that is used as a fabric in which the skin side fabric and the back fabric are knitted with raw yarns having different single yarn fineness, the single yarn fineness of the raw yarn that knitting the skin side fabric is usually A thin yarn of 2.0T or less is used, and a yarn having a single yarn fineness of the yarn for knitting the back side fabric is used, whereas in the present invention, the opposite single yarn is used. An original yarn having a fineness is used.

  In order to secure a good feeling of preventing rewetting and comfort, the ratio of the single yarn fineness of the raw yarn knitting the back side fabric 3 and the single yarn fineness of the raw yarn knitting the skin side fabric 2 is 1: 1. It is preferably selected in the range of 5 to 1: 4, more preferably selected in the range of 1: 1.8 to 1: 3.

  Hydrophobic yarns are selected as the yarns for knitting the skin side fabric 2 and the back fabric 3 and, for example, synthetic fibers such as polyester, nylon, and polypropylene are preferably used. Among these, it is preferable to use polyester from the viewpoints of fastness, texture, and dyeability.

  Since the back side fabric 3 is knitted with raw yarns smaller than the single yarn fineness of the raw yarn knitting the skin side fabric 2, a relatively thin and dense fabric can be realized, and the skin side fabric 2 The back side ground tissue 3 is more attracted to the skin side ground tissue 2 side by the tension of the raw yarn of the skin side ground tissue 2 pulled out by the raising process.

  As a result, the water infiltrated from the skin side ground tissue 2 is quickly absorbed by the good capillary phenomenon by the dense back side ground tissue 3 and diffuses in the surface direction of the fabric, effectively preventing rewetting. In addition, in the back side fabric 3 knitted with the hydrophobic raw yarn, moisture is quickly stored in the surrounding yarn by the capillary phenomenon of the back side fabric without storing water in the raw yarn. The infiltrated water comes to transpiration quickly while preventing rewetting.

  Further, the skin side fabric 2 is knitted with a hydrophobic yarn having a single yarn fineness larger than the single yarn fineness of the yarn for knitting the back fabric 3, and the surface thereof is raised so that it is formed by raising treatment. The gap 2a is formed between the ground tissue 2 and the skin surface by the loop 2a, so that wetting back to the skin surface due to moisture infiltrated from the skin side ground tissue 2 to the back side ground tissue 3 is effectively suppressed. And since the said loop 2a is comprised with the raw yarn whose single yarn fineness is larger than the back side ground structure 3, it has moderate elasticity and maintains the space formed between the skin side ground structure 2 and the skin surface. Good comfort can be ensured. Accordingly, it is possible to effectively suppress the rewetting to the skin due to moisture infiltrated into the fabric from the skin side.

  The anti-wetting fabric 1 can be knitted using a warp knitting machine such as a tricot machine, a loom, a circular knitting machine, or the like provided with at least two front and rear ridges.

  FIGS. 2 to 4 show knitting organization charts of warp knitted fabrics knitted using a warp knitting machine. FIG. 2 shows a satin warp knitted fabric with a single satin knitting with front warp F warp and a single tricot knitting with back warp B warp, and FIG. 3 shows a single cord knitting with front warp F warp. A warp knitted fabric of a half tricot knitted with a single tricot knitting with a back warp B warp is shown. FIG. 4A shows a chain knitting with a warp of a front heel F, a single cord knitting with a warp of a back heel B, and the like. A warp knitted fabric of a quins cord knitting is shown, and FIG. 4B shows a warp knitted fabric of a sharkskin knitting in which a single tricot knitting is performed with a warp of a front heel F and a cord knitting is performed with a warp of a back heel B. .

  The satin knitted warp knitted fabric shown in FIG. 2 is preferably used in the wetting-back preventing fabric according to the present invention. The skin side fabric 2 is knitted with the warp of the front heel F, the back fabric 3 is knitted with the warp of the back heel B, and the skin side fabric 2 is raised with a raising machine after the knitting of the warp knitted fabric.

  Although it is possible to set the outpost to (4 × 1) or (5 × 1), it is most preferable to set it to the normal (3 × 1). In particular, the length of the loop before raising treatment is preferably in the range of 2.5 mm to 3.5 mm. This is because when the loop is short, the raising cloth of the raising machine does not hang onto the loop and the brush cannot be raised smoothly, and when the loop is too long, the loop is easily caught when commercialized.

  Furthermore, the warp knitted fabric of the half tricot knitting shown in FIG. 3 can also be used as an anti-wetting back fabric. The skin side fabric 2 is knitted with the warp of the front heel F, and the back side fabric 3 is formed with the warp of the back heel B. Be organized.

  Similarly, other knitted structures such as pile knitting such that the length of the loop before raising treatment is in the range of 2.5 mm to 3.5 mm are also suitable.

  In the quinz cord knitting of FIG. 4A and the sharkskin warp knitted fabric of FIG. 4B, a fabric with a large swing is arranged on the rear heel B, and the fabric with a large swing is knitted with the front heel. Since it is not a tissue fabric suitable for raising and raising, it cannot be suitably used as a wetting-back preventing fabric.

  FIG. 1C shows a boxer brief, which is an example of a male undergarment 4 partially sewn with the above-described anti-wetting back fabric 1. The above-described wetting-back preventing fabric 1 is superimposed on at least a part of the back side of the front fabric 5 knitted with water-absorbing raw yarn, in the drawing, on the back surface of the front gusset portion 4a.

  As the raw yarn for knitting the back side fabric 3, the wetting prevention fabric 1 uses polyester fibers having a single yarn fineness of 2.8T and a filament number of 12F as a raw yarn for knitting the back side fabric 3. A polyester fiber having a single yarn fineness of 5.6 T and a filament number of 15 F is used.

  As shown in FIG. 1 (b), an intermediate fabric 6 similar to the outer fabric knitted with water-absorbing raw yarn is superimposed between the front fabric 5 and the anti-wetting back fabric 1, and at least the outer fabric side of the intermediate fabric 6 The surface 6a and the outer garment-side surface 5a of the front fabric 5 are water-repellent.

  Accordingly, even when a relatively large amount of moisture infiltrates into the anti-wetting back fabric 1, the outer garment-side surface 6 a of the intermediate fabric 6 is water-repellent, so that the moisture passes through the intermediate fabric 6 and the front fabric 5. In addition, the moisture that has infiltrated into the wetting-back preventing fabric 1 is quickly absorbed on the skin side surface side of the intermediate fabric 6 and diffused in a planar shape. That is, the intermediate fabric 6 functions as a water retention layer. Furthermore, since the surface 5a of the front fabric 5 is water-repellent, an inconvenient situation that oozes out to the outerwear 7 such as trousers and shirts is also eliminated.

  As the raw yarn for knitting the front fabric 5, ultrafine fibers having water absorption properties such as natural fibers such as cotton, regenerated cellulose fibers such as cupra and viscose rayon, and synthetic fibers such as water-absorbed polyester are used. In addition, milling, tengu knitting, and the like are suitable as the knitted fabric. Moreover, it is preferable that the whole surface of the surface fabric 5 is water-repellent.

  Furthermore, it is preferable that the surface fabric 5 and / or the anti-wetting back fabric 1 described above is deodorized and antibacterial processed, thereby suppressing the generation of odor due to urine and sweat and ensuring a comfortable state for a long time. can do.

  For example, as disclosed in Japanese Patent No. 3787675, fibers serving as a raw yarn are treated with a treatment liquid containing chitosan and / or modified chitosan, a carboxylic acid polymer, zinc oxide and a binder resin to form these coating layers. By using the prepared fibers, it is possible to obtain a fabric such as an underwear having an excellent deodorizing effect and having good washing resistance (durability).

  In other words, the underwear fabric according to the present invention has the anti-wetting back fabric 1 superimposed on at least a part of the back side of the front fabric knitted with water-absorbing raw yarn, and the surface of the front fabric is water-repellent. Good.

  Further, it is only necessary that an intermediate fabric knitted with water-absorbing raw yarn is superimposed between the front fabric and the anti-wetting fabric, and at least the outer garment side surface of the intermediate fabric is water-repellent.

  And the underwear by this invention should just sew the underwear using the wet-back prevention fabric 1 mentioned above to the places where prevention of wet-back is required, such as a perspiration part and a urine leak part. It can be used not only for normal underwear, but also for sports inners. When used for an inner for sports, it is also possible to comprise only the anti-wetting fabric 1.

  FIG. 5 shows an example of a ladies' underwear 9 in which a sweat pad 8 using the anti-wetting back fabric 1 as a skin wearing fabric is sewn in an arm hole 10. The sweat pad 8 is formed in a substantially semicircular shape and is integrally sewn so that a part thereof is exposed at the lower portion of the arm hole 10.

  The perspiration pad 8 may be composed of only the anti-wetting fabric 1, but the anti-wetting fabric 1 has a decorative surface by superimposing a water-repellent surface fabric on the outer garment-side surface. Alternatively, an intermediate fabric knitted with a water-absorbing raw yarn may be interposed between the front fabric and the anti-wetting fabric 1. Also in this case, it is preferable that the outer garment side surface of the intermediate fabric is water repellent.

  In addition to the underwear, the sweat pad 8 may be integrally sewn under the arm hole such as a tank top or camisole worn as an outer.

  Furthermore, the perspiration pad 8 can be configured not only to be used for sewing directly to clothes but also to be detachably attached to clothes. The shape of the sweat pad 8 is not particularly limited, and can be appropriately selected depending on the application, such as a circular shape, an oval shape, or a half-moon shape.

  As described above, the underwear using the anti-wetting fabric according to the present invention is lightweight, thin and excellent in comfort and has no change in appearance from other general underwear. Can be worn without resistance.

  The anti-wetting fabric according to the present invention can be suitably used as a lining for underwear that quickly absorbs moisture due to unpleasant urine leakage and sweat, regardless of gender, and as a lining for sweat pads and infant diaper covers, Furthermore, it can be used for various purposes such as sports inners.
