Abstract

The swimsuit of the present invention is made of a stretchable fabric, and water-absorbing gel adsorbing particles in which a water-absorbing gel resin is adsorbed to porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with a binder resin. Thereby, the swimsuit which provided hydrophilicity to the fiber surface of elastic cloth is provided. Since the water-absorbing gel resin is adsorbed on the porous inorganic particles, the water-absorbing gel resin does not swell apparently and does not change in size even when it gets wet, and is imparted with hydrophilicity. The part (1) to which the water-absorbing gel adsorbent particles are fixed becomes hydrophilic, increases the affinity with water, improves the drainage property, and reduces the frictional resistance with water as a whole.

Description

  The present invention relates to a swimsuit in which hydrophilicity is imparted to the fiber surface and a method for producing the same.

  One function required for a swimsuit is to reduce the surface frictional resistance of the swimsuit that occurs during swimming, and various techniques for reducing the surface frictional resistance of the swimsuit have been proposed. For example, in Patent Document 1, polyethylene monooxide having a molecular weight of 4,000,000 to 5,000,000 is made into an aqueous solution and attached to the surface of a swimsuit. However, this technique has a problem that the adhered polymer dissolves in the water and pollutes the water in the pool. Further, Patent Document 2 proposes that a water repellent process is performed on the entire surface of the swimsuit and a hydrophilic process is performed using a binder resin at an arbitrary position. However, the binder resin alone has a problem that the hydrophilicity is insufficient and the frictional resistance of the surface cannot be reduced. As another proposal, Patent Documents 3 to 4 disclose techniques for providing a water-repellent portion and a non-water-repellent portion on the fabric surface for the purpose of reducing the frictional resistance on the fabric surface and ensuring water drainage.

  In the prior art, the resistance reduction effect is exhibited by providing a water-repellent part and a non-water-repellent part on the fabric surface. Further, increasing the water repellent area increases the effect of reducing the frictional resistance, but conversely, the water drainage property of the water that has entered the bathing suit is lowered and the wearing resistance tends to increase. Therefore, if the width of the striped water-repellent part is widened and the area ratio occupied by the non-water-repellent part is reduced, the effect of reducing the frictional resistance is offset by the increase in wearing resistance due to the decrease in water drainage, and the relative resistance There has been a problem that increases.

In addition, in order to increase the water-repellent area, when the water-repellent part is intermittently provided in the stripe direction in the stripe-shaped non-water-repellent part and the water-repellent part is formed in a so-called ladder shape, the resistance due to the increase in the water-repellent area Although there is a reduction effect, there is a problem that the frictional resistance reduction effect is small because the portion corresponding to the rung of the ladder-like water repellent portion is orthogonal to the water flow during swimming. In order to improve this, at least a part of the swimsuit surface has a continuous water-repellent part that has been subjected to continuous water-repellent treatment, a water-repellent part that has been subjected to water-repellent process, and a non-water-repellent part that has not been subjected to water-repellent process. It has been proposed to form intermittent water-repellent portions formed intermittently in stripes parallel to the body length direction (Patent Document 5).

  As described above, swimwear has been variously improved, but there is a demand for further improving the frictional resistance in water.

  The inventors have noted that the skin and scales of mammals such as fish and whales that live in water are essentially hydrophilic. The present invention reviews the basic idea and provides a swimsuit in which hydrophilicity is imparted to the fiber surface of a stretchable fabric and a method for producing the same.

  The swimsuit of the present invention is a swimsuit made of stretchable fabric, wherein water-absorbing gel adsorbent particles in which a water-absorbing gel resin is adsorbed on porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with a binder resin. It is characterized by being.

  The method for producing a swimsuit according to the present invention is a method for producing a swimsuit comprising a stretchable fabric, wherein the water-absorbing gel adsorbent particles in which the water-absorbent gel resin is adsorbed on the porous inorganic particles are combined with at least the surface of the stretchable fabric together with the binder resin It is given to a part.

FIG. 1A is a front view of a female swimsuit according to an embodiment of the present invention, and FIG. 1B is a rear view thereof. FIG. 2 is an enlarged view of FIG. 1, showing a state in which a hydrophilic fabric portion and an intermittently formed water-repellent portion on the surface thereof are arranged. FIG. 3 is a schematic explanatory view of a surface friction resistance test apparatus in water used in the embodiment of the present invention. 4A is a front view of a men's swimsuit according to another embodiment of the present invention, FIG. 4B is a side view thereof, and FIG. 4C is a rear view thereof. FIG. 5 is a schematic conceptual view of porous inorganic particles (aggregated particles) in one embodiment of the present invention. FIG. 6 shows a pattern of a swimsuit fabric according to another embodiment of the present invention. FIG. 7 shows a pattern of a swimsuit fabric according to another embodiment of the present invention. FIG. 8 shows a pattern of a swimsuit fabric according to another embodiment of the present invention.

  In the swimsuit of the present invention, the water-absorbing gel adsorbing particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with the binder resin. Since the water-absorbing gel resin is adsorbed on the porous inorganic particles, the water-absorbing gel resin does not swell apparently and does not change in size even when it gets wet. It is only done. As a result, the portion where the water-absorbing gel adsorbing particles are fixed becomes hydrophilic. Hereinafter, the part to which such particles are fixed is referred to as “hydrophilic part”. Thereby, the affinity with water is increased, the water drainage is improved, and the frictional resistance with water is lowered as a whole. In addition, it is difficult to fix to the fabric with high durability even if it is used in combination with the binder resin alone, but the water-absorbing gel adsorbent particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles are expanded and contracted together with the binder resin. By being fixed to the sex cloth, it can be fixed to the cloth with high durability. As a result, a highly durable hydrophilic surface is obtained.

  In the swimsuit of the present invention, the water-absorbing gel adsorbing particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with the binder resin. The water-absorbing gel resin is usually used in a diaper or the like, and has a property of absorbing water several times to several hundred times as much as its own weight and swelling due to absorption. However, it is considered that when the water-absorbing gel resin is used alone, it absorbs water and swells to increase the frictional resistance with water. Therefore, in the present invention, the water-absorbing gel resin is used by being adsorbed on the porous inorganic particles.

In order to adsorb the water-absorbing gel resin to the porous inorganic particles, for example, silica (SiO ₂ ), zeolite, alumina (Al ₂ O ₃ ) particles, calcium carbonate, boron nitride, mica, titania (TiO ₂ ), zirconia, activated carbon, etc. The porous inorganic particle powder is mixed with a saturated water-absorbing gel resin and dried. As the porous inorganic particle powder, primary particles may be used as they are (for example, activated carbon) or aggregated particles (for example, silica) obtained by aggregating the primary particles. In the case of using aggregated particles, the primary particles are mixed with water-absorbed gel resin, and the primary particles are aggregated during drying to form aggregated particles. In the above, the primary particles do not necessarily need to be porous, and may be porous to the extent that the water-absorbing gel resin is contained inside when the aggregated particles are formed.

  The water-absorbing gel resin of the present invention is also referred to as a highly water-absorbing resin, and is a crosslinked body of a hydrophilic linear or branched polymer, has a three-dimensional network structure in angstrom units, and dissolves in water when contacted with water. However, it is suppressed because of the cross-linked structure between the molecules, and due to the balance, a hydrogel in a swollen state in which a certain amount of water is supplied is obtained. The water absorbed in this way is unlikely to separate even when pressure is applied, unlike water taken in by porous holes or capillarity such as sponge or cotton-like pulp. Those having a water absorption of 10 g or more per 1 g of resin are generally called highly water-absorbing resins.

  The mixing ratio of the water-absorbing gel resin and the porous inorganic particle powder is adjusted so that the water-absorbing gel resin swells from the powder particles and does not come out when the swimsuit is later wetted. For example, in the case of a water-absorbing gel resin that swells 35 times by water absorption, about 2 to 6% by volume in terms of dry volume is adsorbed per 100% by volume of pores of the powder particles. Alternatively, the volume of the water-absorbing gel resin with saturated water absorption is set in the range of 50 to 250% by volume per 100% by volume of the pores of the powder particles. The reason why a little more water-absorbing gel resin may be blended is that complete water absorption may not be possible in the pores of the porous inorganic particles. When adsorbing the water-absorbing gel resin to the porous inorganic particles, a binder resin may be mixed. As the binder resin, resins such as N-methylol (urea), sulfone, epoxy, glyoxal, polycarboxylic acid, acrylic, acrylic silicon, and urethane can be used.

  The water-absorbing gel adsorption particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with the binder resin. As the binder resin, resins such as N-methylol (urea), sulfone, epoxy, glyoxal, polycarboxylic acid, acrylic, acrylic silicon, and urethane can be used. These resins are selected so as not to impair the texture.

  In the present invention, the water-absorbing gel adsorbing particles may be fixed to at least a part of the surface of the stretchable fabric. Preferably, the water-absorbing gel adsorbing particles are fixed to an area of 10% or more with respect to the surface of the swimsuit. The area is more preferably 50% or more, and particularly preferably 70% or more.

  The water-absorbing gel adsorbing particles can be made into a dispersion together with the binder resin and applied to the stretchable fabric by dipping. In this case, the adsorption gel particles are fixed on the entire surface of the stretchable fabric. Further, the water-absorbing gel adsorbing particles can be made into a dispersion together with the binder resin and applied to the stretchable fabric by printing. In this case, it can be fixed to a part of the surface of the stretchable fabric.

The amount of the water-absorbing gel adsorbent particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles is preferably 5 to ²⁰ g / m ² although it depends on the kind of the fabric. Adhesion amount of the binder resin of the stretch fabric, 0.5 to 20 g / m ² is preferred.

  The water-absorbing gel resin may be any material as long as it can be used as a material for diapers. For example, a solution obtained by mixing acrylic acid, polyethylene glycol diacrylate, diethylenetriaminepentaacetic acid / 5 sodium solution, and sodium hydroxide solution And a water-absorbing gel resin having a crosslinked structure by mixing and polymerizing an aqueous sodium persulfate solution.

  At least a part of the swimsuit surface of the present invention may further contain a water-repellent part. As the water repellent, silicone water repellent, fluorine water repellent and the like can be used. The treatment agent used for the water repellent portion may have a name such as a printing agent or a sealing agent.

  The water-repellent part and the hydrophilic part may be formed continuously along the body length direction of the swimsuit or may be formed intermittently. Further, a continuous state and an intermittent state may be mixed. When a hydrophilic portion is present, water drainage is excellent.

  In order to form the water-repellent part on the surface of the fabric, a generally industrialized print formulation is suitable, and the apparatus used is appropriately selected from a roller printing machine, an auto screen printing machine, a hand screen printing machine, etc. Is done.

The amount of the water repellent applied to the fabric varies depending on the basis weight of the base fabric, the thickness, the water repellent processed area, the type of the water repellent and the like, but is preferably 5 to ²⁰ g / m ² .

  The area ratio between the water-repellent part and the hydrophilic part is as follows: hydrophilic part: water-repellent part = 10 to 90:90 to 10, more preferably 50 to 80:50 to 20, further preferably 60 to 80:40 to 20, Especially preferably, it is the range of 70-80: 30-20. It is preferable that the hydrophilic portion has a large area. It is preferable that the hydrophilic portion is formed on the entire surface by a dipping method, and the water-repellent portion is formed thereon by printing.

  In the present invention, a water repellent portion may be further formed on the back surface of the swimsuit. When forming the water-repellent part on the back surface, the area ratio of the water-repellent part on the back surface is preferably in the range of 10 to 90%. In this way, the water retention rate of the fabric of the swimsuit itself can be reduced, and the water resistance can be further reduced. When forming a water-repellent part on the back surface, a continuous or intermittent pattern can be adopted like the front surface, for example, a vertical stripe shape, a horizontal stripe shape (border pattern), an oblique stripe shape, a polka dot pattern, a lattice pattern, or A design combining these arbitrarily can be applied.

  The fabric used for the swimsuit of the present invention is made of synthetic fiber multifilament yarns such as polyamide, polyester and polypropylene, or knitting or weaving of these synthetic fiber multifilament yarns and polyurethane elastic yarns. Knitted fabrics and woven fabrics can be used. In particular, swimsuits for swimming often place importance on easiness of movement, and as a material form, a knitted fabric obtained by knitting synthetic fiber multifilament yarn and polyurethane elastic yarn is more preferable. In addition, as the knitted fabric form, a single circular knitted fabric that is a circular knitted fabric, a double circular knitted fabric, a tricot fabric that is a warp knitted fabric, or a russell fabric can be used, but stretch properties that affect the ease of movement. Tricot fabric is more preferable from the viewpoint of fabric thinness. This is dyed and finished by an ordinary dyeing method to obtain a stretchable fabric.

  The swimsuit of the present invention is suitable for swimming.

  Next, the stretchable fabric constituting the swimsuit of the present invention and its physical properties will be described.

(1) Stretchability As for the elongation at the time of 4.9N (500 gf) load measured according to JIS1096, a knitted fabric in which at least one selected from the warp direction and the weft direction is in the range of 5 to 150% is preferable. If it is in this range, it follows the movement of the body and is highly wearable.

(2) weight of the basis weight stretchable fabric is preferably in the range of 100 to 400 g / m ^2. Within this range, problems such as sheer do not occur, it is suitable for aesthetics, and there is no feeling of weight and wearability is high.

  This will be described below with reference to the drawings. FIG. 1A is a front view of a women's swimsuit according to one embodiment of the present invention, and FIG. 1B is a rear view thereof. This swimsuit is composed of a hydrophilic fabric portion 1 and an intermittent water-repellent portion 2 on the surface thereof. The hydrophilic fabric portion 1 is obtained by adhering water-absorbing gel adsorbent particles together with a binder resin to the fabric by an immersion method and fixing the particles. The water repellent portion 2 can be formed by printing a water repellent resin.

  FIG. 2 is an enlarged view of FIGS. 1A-B and shows the arrangement and shape of the hydrophilic fabric portion 1 and the intermittent water-repellent portion 2 on the surface thereof.

  4A is a front view of a men's swimsuit according to another embodiment of the present invention, FIG. 4B is a side view thereof, and FIG. 4C is a rear view thereof. The swimsuit pattern, the hydrophilic fabric portion, and the intermittent water-repellent portion of the surface are the same as in FIG.

  FIG. 5 is a schematic conceptual view of porous inorganic particles (aggregated particles) in one embodiment of the present invention. The porous inorganic particles (aggregated particles) 5 include the water-absorbing gel resin 3 between the inorganic primary particles 4. When the water-absorbing gel resin 3 contacts with water, the water-absorbing gel resin 3 absorbs a predetermined amount of water. The (aggregated particles) 5 as a whole becomes hydrophilic. However, since the water-absorbing gel resin 3 is present in the porous inorganic particles (aggregated particles) 5, the porous inorganic particles (aggregated particles) 5 themselves do not swell apparently due to the absorption of water.
