Description

Swimsuit and method of manufacturing same

The present invention relates to a swimsuit which imparts hydrophilicity to the surface of a fiber and a method of producing the same.

One of the functions required for swimsuits is how to reduce the surface frictional resistance of the swimsuits produced in the swimming pool. So far, various techniques have been proposed for reducing the surface friction resistance of the swimsuits. For example, in Patent Document 1, a polyethylene monoxide having a molecular weight of 4,000,000 to 5,000,000 is made into an aqueous solution and adhered to the surface of the swimsuit. However, the problem with this technique is that the attached polymer will dissolve in the water and contaminate the water in the swimming pool. Further, in Patent Document 2, it has been proposed to perform water repellent processing on the entire swimsuit and to perform hydrophilic processing using a binder resin at an arbitrary position. However, when only a binder resin is used, the hydrophilicity is insufficient, so that the surface friction resistance cannot be reduced, which is a problem. Other proposals, such as those disclosed in Patent Documents 3 to 4, are to provide a water-repellent portion and a non-water-repellent portion on the surface of the cloth in order to reduce the frictional resistance of the cloth surface and ensure drainage.

In the prior art, the water-repellent portion and the non-water-repellent portion are provided on the surface of the cloth to exert the effect of reducing the resistance. Further, the effect of reducing the frictional resistance can be increased by increasing the water-repellent area, but conversely, the water immersion in the swimsuit is lowered, and the wearing resistance tends to increase. If the width of the stripe-shaped water-repellent portion is increased and the area ratio of the non-water-repellent portion is reduced, the effect of reducing the frictional resistance is offset by an increase in the wear resistance caused by a decrease in the drainage property, resulting in a relative The increase in ground resistance is the problem.

Further, in order to increase the water-repellent area, the water-repellent portion is intermittently provided in the stripe-shaped non-water-repellent portion in the stripe direction, and the water-repellent portion is formed into a so-called ladder shape, and the water-repellent area is increased to reduce the resistance. The effect is that the portion of the ladder-shaped water-repellent portion corresponding to the cross-section is orthogonal to the flow of water during swimming, so the frictional resistance reduction effect is small, which is a problem. In order to improve this point, it has been suggested that at least a part of the surface of the swimsuit makes the continuous water-drawing part which is continuously subjected to water-discharging processing, and the water-repellent part which is intermittently formed with water-discharging processing and the water-repellent processing which is not performed. The intermittent water-repellent portion formed by the non-water-removing portion is formed in a parallel stripe shape in the length direction (Patent Document 5).

As described above, although there have been various improvements in the swimsuit since the past, it is still required to further improve the frictional resistance in water.

The inventors of the present invention have noticed that the skin or scales of fish, such as fish, or whales, which are inhabited in water, are hydrophilic in nature. The present invention revisits the basic idea and provides a swimsuit having a hydrophilic surface on the surface of the fiber of the stretchable cloth and a method of manufacturing the same.

The swimsuit of the present invention is composed of a stretchable fabric, and the absorbent colloid-adsorbing particles obtained by adsorbing the water-absorbent colloidal resin to the porous inorganic particles are fixed to at least one of the surfaces of the stretchable fabric together with the binder resin. Share.

The manufacturing method of the present invention is for producing a swimsuit comprising a stretchable fabric, characterized in that the water-absorbing colloid-adsorbing particles formed by adsorbing a water-absorbent colloidal resin to the porous inorganic particles are provided with a stretchable resin together with the binder resin. At least a portion of the surface of the cloth.

In the swimsuit of the present invention, the water absorbing colloid-adsorbing particles obtained by adsorbing the water-absorbent colloidal resin to the porous inorganic particles are fixed to at least a part of the surface of the stretchable cloth together with the binder resin. The water-absorbent colloidal resin is adsorbed on the porous inorganic particles, and even if it is wetted by water, the water-absorbent colloidal resin does not exhibit apparent swelling, and since it does not cause dimensional change, it imparts hydrophilicity only without causing resistance. . As a result, a portion in which the water absorbing colloid adsorbing particles is fixed becomes hydrophilic. Hereinafter, the portion to which the particles are fixed is referred to as a "hydrophilic portion". Thereby, the affinity with water can be improved, the drainage property can be improved, and the frictional resistance with water as a whole can be reduced. Further, when only the water-absorbent gel resin is used, it is difficult to fix the fabric to the fabric with high durability even when used in combination with, for example, a binder resin, and the water-absorbent colloid-adsorbing particles and the binder formed by adsorbing the water-absorbent colloidal resin to the porous inorganic particles. The resin is fixed to the stretchable fabric together and can be fixed to the stretchable fabric with high durability. As a result, a highly durable hydrophilic surface can be obtained.

In the swimsuit of the present invention, at least a part of the surface of the stretchable cloth is simultaneously fixed with the water-absorbent colloid-absorbing particles and the binder resin in which the porous inorganic particles are adsorbed with the water-absorbent gel resin. The water-absorbent colloidal resin is usually used in a diaper or the like, and has a property of absorbing several to several hundred times of its own weight and swelling depending on the amount of absorption. However, it is believed that if the water-absorbent colloidal resin is used alone, it will absorb water and swell, resulting in an increase in frictional resistance with water. Therefore, in the present invention, the water-absorbent gel resin is adsorbed to the porous inorganic particles and used.

In order to adsorb the water-absorbent colloidal resin to the porous inorganic particles, for example, cerium oxide (SiO ₂ ), zeolite, alumina (Al ₂ O ₃ ) particles, calcium carbonate, boron nitride, mica, titanium dioxide (TiO) ₂ ) A porous inorganic particle powder such as zirconium dioxide or activated carbon is obtained by mixing a saturated and water-absorbent colloidal resin and drying it. As the porous inorganic particle powder, primary particles (for example, activated carbon) can be used as it is. Aggregated particles (for example, cerium oxide) in which primary particles are aggregated can also be used. In the case of using aggregated particles, the water-absorbing colloidal particle resin may be mixed with the primary particles to form agglomerated particles by aggregating the primary particles during drying. In the above, the primary particles are not necessarily required to be porous, and may be porous as long as they are agglomerated particles.

The water-absorbent colloidal resin of the present invention, also referred to as a superabsorbent resin, is a crosslinked body of a hydrophilic linear or branched polymer, and is a three-dimensional network structure of an angstrom unit, when in contact with water, Water is absorbed by the force to be dissolved in water, but it is suppressed by the cross-linking structure between the molecules, and by its balance, it becomes a hydrogel which absorbs a certain amount of swelling state. The water thus absorbed is different from the water sucked through the porous pores or capillary phenomenon like sponge or cotton pulp, and it is difficult to discharge even if pressure is applied. The amount of water per 1 g of the resin is 10 g or more, and it is usually called a super absorbent resin.

The mixing ratio of the water-absorbent colloidal resin to the porous inorganic particle powder is such that the volume ratio of the two is adjusted so that the water-absorbent colloidal resin swells when the swimsuit is wet, but does not exceed the powder particles. For example, in the case of a water-absorbent colloidal resin which is swelled by water absorption by 35 times, the powder particle voids (holes) are adsorbed in an amount of about 2 to 6% by volume in terms of dry volume per 100% by volume. Or, for every 100% by volume of the voids (holes) of the powder particles, the volume of the water-absorbent colloidal resin which satisfactorily absorbs water is in the range of 50 to 250% by volume. The reason why the water-absorbent colloidal resin can be blended in a large amount is that the pores (pore) of the porous inorganic particles may not be completely absorbed. When the water-absorbent colloidal resin is adsorbed to the porous inorganic particles, the binder resin may be mixed. As the binder resin, resins such as N-methylol (urea), fluorene, epoxy, glyoxal, polycarboxylic acid, acrylic, decyloxy, and amine esters can be used.

The water-absorbent colloid-adsorbing particles obtained by adsorbing the water-absorbent colloidal resin to 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), fluorene, epoxy, glyoxal, polycarboxylic acid, acrylic, decyloxy, and amine esters can be used. The choice of such resins is based on considerations that do not compromise the texture.

In the present invention, the water-absorbent colloid-adsorbing particles may be fixed to at least a part of the surface of the stretchable cloth. Preferably, the surface of the swimsuit is fixed to the water-absorbing colloid to adsorb particles up to 10% or more. The better is 50% or more, especially 70% or more.

The water absorbing colloid-adsorbing particles can be used as a dispersion together with the binder resin, and the stretchable fabric can be applied by dipping. In this case, the adsorbed colloidal particles are fixed to the entire stretch fabric. Further, the water absorbing colloid-adsorbing particles may be used as a dispersion together with the binder resin, and may be applied to a part of the surface of the stretchable fabric by printing. In this case, it can be fixed to one of the surfaces of the stretchable fabric.

The amount of the water-absorbent colloid-adsorbing particles formed by adsorbing the water-absorbent colloidal resin on the porous inorganic particles to the stretchable fabric varies depending on the type of the fabric, and is preferably 5 to 20 g/m ² . The adhesion amount of the binder resin to the stretchable cloth is preferably 0.5 to 20 g/m ² .

The water-absorbent colloidal resin may be any material as long as it can be used as a diaper material, for example, a solution in which an aqueous solution of acrylate, polyethylene glycol diacrylate, diethylenetriamine pentaacetic acid pentasodium is mixed, and A water-absorbent colloidal resin having a crosslinked structure obtained by mixing an aqueous solution of sodium hydroxide and an aqueous solution of sodium persulfate to carry out polymerization.

At least a portion of the surface of the swimsuit of the present invention may further contain a water-repellent portion. The water repellent can be used: a decane-based water repellent, a fluorine-based water repellent, and the like. Further, the treatment agent used in the water-repellent portion may also be referred to as a printing agent or a sealing agent.

The water-repellent portion and the hydrophilic portion may be formed in a continuous shape along the length direction of the swimsuit, or may be formed in a discontinuous shape. More continuous and intermittent mixed. If a hydrophilic portion is present, the drainage property is excellent.

In order to form the aforementioned water-repellent portion on the surface of the cloth, it is generally preferred to use an industrial printing process, and the device to be used may be suitably selected from a roller-printing machine, an automatic screen printing machine, and a manual. A screen printing machine or the like.

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

The ratio of the area of the water-repellent part to the hydrophilic part is the hydrophilic part: the water-repellent part=10~90:90~10, preferably 50~80:50~20, 60~80:40~20 Better, especially 70~80:30~20 is especially good. The hydrophilic portion is preferably a wide range, and preferably, a hydrophilic portion is formed entirely by a dipping method, and a water-repellent portion is formed thereon by a printing method.

In the present invention, a water-repellent portion may be further formed on the inner surface of the swimsuit. When the water-repellent portion is formed on the inner surface, the area ratio of the water-repellent portion of the inner surface is preferably in the range of 10 to 90%. In this way, the water retention rate of the fabric of the swimsuit can be reduced, and the resistance of the water can be further reduced. When the water-repellent portion is formed on the inner surface, a continuous or intermittent pattern can be used similarly to the surface, and for example, a vertical stripe shape, a horizontal stripe shape (border pattern), a diagonal stripe pattern, and a water drop pattern can be used. , a plaid pattern, or a design in which these are arbitrarily combined.

Moreover, the braid form can be a single circular knitted fabric, a double circular knitted fabric, a warp knitted tricot fabric, a raschel warp ( Any of raschel fabrics. In view of the stretchability and the thinness of the cloth which have an influence on the easiness of the action, it is preferable to use a woven fabric. This is dyed by a usual dyeing method to form a cloth.
