Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since these fibers are synthetic fibers, mainly synthetic fibers, particularly polyester fibers, the dyeability of cotton fibers and polyester fibers is different, uniform dyeing is difficult, and the texture is not optimal. Furthermore, although general polyester fibers are widely used as the main material, they do not decompose naturally, so there is a problem of disposal after use. In addition, those obtained by resin-treating cotton fibers or applying a strong twist to the core have problems in terms of texture and washing resistance. In recent years, from the perspective of the Sustainable Development Goals (SDGs) defined by the United Nations, cotton fibers have been reexamined as inner clothing such as underwear. However, no technology has been found that has excellent texture, washing resistance, and quick-drying property with cotton itself as the main material.

[0006] In order to solve the above-mentioned conventional problems, the present invention imparts quick-drying property to cellulose fibers typified by cotton fibers, and has excellent water absorbency, comfort, and washing resistance in terms of the environment, as well as Raw material, quick-drying fabric and to provide quick-drying clothing.

Embodiments for Carrying Out the Invention

[0012] The yarn of the present invention is a spun yarn containing cellulose fibers. Cellulose fibers include natural fibers such as cotton and hemp, and chemical fibers such as rayon. Among these, cotton, which is the most versatile as clothing, is preferred.

[0013] The yarn of the present invention includes cellulose fibers graft-bonded with a quick-drying monomer and untreated cellulose fibers. Examples of the quick-drying monomer for graft-bonding include so-called hydrophobic compound monomers and monomers that inhibit the contact between the hydroxyl groups of cellulose fibers and liquid-phase water. For example, silicone-based compounds containing at least two or more ethylenically unsaturated double bonds, compounds containing at least two or more ethylenically unsaturated double bonds and alkoxy groups, compounds containing at least two or more ethylenically unsaturated double bonds and urethane bonding groups, and the like. As the silicone-based compound, for example, an acrylic-modified silicone (organopolysiloxane containing an acrylic group) compound is preferable. As the compound containing at least two or more ethylenically unsaturated double bonds and an alkoxy group, for example, ethoxylated pentaerythritol tetraacrylate is preferable. Examples of the compound containing at least two or more ethylenically unsaturated double bonds and a urethane bonding group include urethane acrylate compounds.

[0014] The quick-drying monomer is preferably graft-bonded to the cellulose fibers by electron beam irradiation. The graft-bonding involves various reactions, such as a reaction to generate radicals on the surface of the cellulose-based fibers by irradiating with an electron beam, a reaction to graft-bond to the surface of the cellulose-based fibers by contacting the generated radicals with a compound having an ethylenically unsaturated double bond containing a functional group (-OH, -NH2, etc.), and a reaction to form a covalent bond by reacting the active group with a carboxylic acid group (-COOH). The quick-drying monomer is preferably added to the cellulose-based fibers in the range of 0.5 to 30% by mass, more preferably 0.5 to 20% by mass. Within this range, the quick-drying function can be exhibited even when blended with untreated cotton.

[0015] The yarn of the present invention is a blended spun yarn or a core-sheath type spun yarn containing cellulose fibers graft-bonded with a quick-drying property-imparting monomer and unprocessed cellulose fibers without quick-drying treatment. The blended spun yarn is preferably blended by a carding machine or in sliver form. The core-sheath type spun yarn is obtained by spinning each fiber bundle from the front roller of a spinning machine, using one as the core, winding the other around the core to form the sheath, and applying twist and winding it up. The moisture content of the yarn of the present invention is about the same as that of raw cotton. That is, when the moisture content is measured after leaving it for 2 hours at a temperature of 20°C and a relative humidity of 95%RH, the moisture content of raw cotton is about 14 - 16%, while the spun yarn of the present invention is about 11 - 16%. For a spun yarn of 80% cotton and 20% polyester, it is less than 10%.

[0016] Next, the fabric of the present invention will be described. The fabric of the present invention is a fabric selected from at least one of a knitted fabric and a woven fabric formed from a blended spun yarn or a core-sheath type spun yarn containing cellulose fibers graft-bonded with a quick-drying property-imparting monomer and unprocessed cellulose fibers without quick-drying treatment, and has water absorption and quick-drying properties. The water absorption in the water absorption and quick-drying property refers to those with a water absorption time of less than 3 seconds in a test conforming to JIS L1907 (dripping method). Preferably, it is less than 1 second. The quick-drying property in the water absorption and quick-drying property means that the diffusible residual moisture content after 60 minutes is lower than that of 100% raw cotton fabric. A preferable quick-drying property is that the diffusible residual moisture content after 60 minutes is 30% or less. The diffusible residual moisture content is calculated by the following formula by dropping about 0.3 ml of water onto the sample at 20°C × 65%RH and measuring the weight at each elapsed time. Diffusible residual moisture content (%) = Moisture weight at each time (g) / Moisture weight immediately after dripping (g) × 100 Regarding the washing durability, it is measured before washing and after washing 10 times. The washing conditions conform to JIS L 0217 103 method.

[0017] When the fabric is 100% by mass, the cellulose fibers graft-bonded with the quick-drying property-imparting monomer are preferably 5 - 40% by mass, and the unprocessed cellulose fibers without quick-drying treatment preferably contain 60 - 95% by mass. Thereby, the quick-drying property becomes good.

[0018] When the base fabric is 100% by mass, the cellulose fiber graft-bonded with the quick-drying monomer is 5 to 40% by mass, the non-quick-drying processed cellulose fiber is 57 to 92% by mass, and it is also preferable that the elastic yarn (C) contains 3 to 15% by mass. Thereby, stretchability can be improved.

[0019] The base fabric is a knitted fabric, and preferably, out of three knitting yarns constituting the fabric, 1 to 2 yarns are the blended or core-sheath type spun yarn, and the remaining yarns are non-quick-drying processed yarns.

[0020] The base fabric is preferably a knitted fabric or a woven fabric. Knitted fabrics and woven fabrics are suitable for inner clothing. In particular, knitted fabrics have elasticity, are flexible, and are suitable for inner clothing. Preferably, out of three yarns constituting the fabric, 1 to 2 yarns are the blended spun yarn, and the remaining yarns are non-quick-drying processed cotton spun yarns. Knitted fabrics include circular knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, etc., and may be any knitting structure such as plain knitting, honeycomb knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, denim structure, cord structure, atlas structure, chain structure, inserted structure, and fabrics combined with these. Various cross-knitting methods are used to produce knitted fabrics. The cross-knitted fabric may be warp knitted or weft knitted, and examples include tricot, raschel, circular knitting, etc. Also, the knitting structure may be any knitting structure such as half knitting, reverse half knitting, double atlas knitting, double denim knitting, and knitted fabrics combined with these. As the woven fabric structure, there are plain weave, twill weave, damask weave, changed plain weave, changed twill weave, changed damask weave, alternative weave, figured weave, single-layered double weave, double weave, multi-layered weave, warp pile weave, weft pile weave, interlaced weave, or a structure combined with these. Among these, weft knitted fabrics including circular knitting or warp knitted fabrics are preferable.

[0021] The mass per unit area (areal density) of the base fabric is preferably 80 to 300 g / m 2 more preferably 90 to 250 g / m 2 even more preferably 100 to 250 g / m 2 If it is within the above range, it is suitable as inner clothing.

[0022] The elastic yarn is preferably at least one selected from a polyurethane yarn and a conjugate yarn obtained by composite spinning of at least two polymers having different shrinkage rates. The polyurethane elastic yarn may be any as long as it is made from polymer diol and diisocyanate as starting materials, and is not particularly limited. The conjugate yarn is a conjugate yarn obtained by composite spinning of at least two polymers having different shrinkage rates, and exhibits crimp (curl) from the stage of the raw yarn, and further exhibits a larger crimp (curl) when heat is applied. Specifically, a conjugate yarn (bicomponent yarn) of polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) is preferable. Examples of such latent crimp type stretch yarns include those manufactured by Toray Oprontex Co., Ltd. under the trade name "Lycra T400", those manufactured by KB Seiren Co., Ltd. under the trade name "Espandy", and those manufactured by Unitika Ltd. under the trade name "Z10". The elastic yarn commonly used is a polyurethane yarn.

[0023] In the case of, for example, weft knitted fabric or circular knitted fabric, the spandex bare yarn is often used as an added yarn for the loop yarn. In the case of warp knitted fabric, the spandex bare yarn is inserted by an insertion structure or by inserting the weft yarn. In the case of so-called inner clothing, circular knitting is usually adopted, and elastic yarn, particularly polyurethane elastic yarn, is used as an added yarn for the loop yarn. The polyurethane elastic yarn is usually inserted as an added yarn in a state where a 30d yarn is stretched about 2.5 times.

[0024] In the clothing sewn with the quick-drying fabric of the present invention, the elastic yarn is arranged in the circumferential direction of the body. It is a so-called one-way stretch fabric. The circumferential direction of the body refers to the circumferential direction of the torso and the circumferential direction of the arm. As a result, it becomes an inner clothing that is comfortable to wear and is not easily out of shape even after repeated washing. This clothing is preferably a shirt or pants. The inner clothing of the present invention has cotton as a main fiber of 85% by mass or more, preferably 88% by mass or more, and more preferably 90% by mass or more, and is an inner clothing gentle on the skin.

[0025] Next, the manufacturing method of the present invention will be described by taking a blended spun yarn using cotton (natural cellulose fiber) as the cellulose fiber as an example. For the cotton sliver for spinning, a hydrophobic compound monomer or a monomer that inhibits the contact between the hydroxyl group of the cellulose fiber and the water in the liquid phase, for example, a silicone-based compound containing at least two or more ethylenically unsaturated double bonds or a compound containing at least two or more ethylenically unsaturated double bonds and an alkoxy group is added. Then, in the case of the continuous method, by irradiating an electron beam in a nitrogen atmosphere, it becomes possible to graft-polymerize a silicone-based compound containing an ethylenically unsaturated double bond and a compound containing an ethylenically unsaturated double bond and an alkoxy group on the surface of the cotton fiber. Note that the step of adding a silicone-based compound containing an ethylenically unsaturated double bond and a compound containing an ethylenically unsaturated double bond and an alkoxy group to the cotton fiber and the step of irradiating the cotton fiber to which the silicone-based compound containing an ethylenically unsaturated double bond and a compound containing an ethylenically unsaturated double bond and an alkoxy group are added with an electron beam may be either continuous or discontinuous. Note that the irradiation of the electron beam may be either before or after (including simultaneously) the addition of the quick-drying property-imparting monomer, but it is preferable to irradiate the electron beam in a nitrogen atmosphere because the generated radicals are less likely to be deactivated.

[0026] The method of bringing a quick-drying property-imparting monomer, for example, a silicone-based compound containing at least two or more ethylenically unsaturated double bonds or a compound containing at least two or more ethylenically unsaturated double bonds and an alkoxy group, into contact with the surface of the cotton fiber may be any method such as an immersion method or a spray method. Note that it is preferable to prepare the quick-drying property-imparting monomer in an aqueous solution and immerse the sliver or spray it onto the sliver for application.

[0027] In the present invention, by blending and spinning the processed spinning sliver and other unprocessed slivers, a spun yarn having quick-drying property while maintaining water absorbency can be obtained. That is, a spun yarn made of a sliver to which a hydrophobic compound is added has a reduced water absorbency, and the water absorbency of a fabric obtained based on such a yarn is not preferable. Blending is usually preferably carried out in a roving process that includes a doubling process. However, it is also possible in a carding process (card), a roving process, and a spinning process. By aligning a plurality of webs, slivers, fleeces, and roving yarns and stretching them at a predetermined magnification, blending can be achieved. In the roving process and the spinning process, blending can be achieved by the migration of constituent fibers when twisting. Furthermore, it is also possible to return the processed spinning sliver to the carding process to obtain a desired blending ratio.

[0028] After blending cotton graft-bonded with the quick-drying property-imparting monomer and unprocessed cotton without quick-drying treatment, a blended spun yarn (A) is obtained according to a conventional method. Also, a spun yarn of unprocessed cotton without quick-drying treatment is made into a spun yarn (B) according to a conventional method. A quick-drying fabric is made using a predetermined amount of the blended spun yarn (A), the spun yarn (B), and the elastic yarn (C). Post-processing such as sunning, dyeing, and soft finishing of this fabric according to a conventional method is optional. The above is an example of a blended spun yarn containing cellulose fibers graft-bonded with a quick-drying property-imparting monomer and unprocessed cellulose fibers without quick-drying treatment, but it may also be a core-sheath type spun yarn containing cellulose fibers graft-bonded with a quick-drying property-imparting monomer and unprocessed cellulose fibers without quick-drying treatment. In this case, it is preferable to configure the core with unprocessed cellulose fibers without quick-drying treatment and the sheath with a blended spun yarn containing cellulose fibers graft-bonded with a quick-drying property-imparting monomer and unprocessed cellulose fibers without quick-drying treatment.

[0029] FIG. 1 is a front view of the inner garment 1 in one embodiment of the present invention. This inner garment 1 is an example of a long-sleeved shirt. Elastic yarns are arranged in the circumferential direction of the body, that is, in the circumferential direction of the torso (arrow 2) and in the circumferential direction of the arm (arrow 3).
