Detailed Description

Hereinafter, embodiments of the present invention will be described in detail. First, in the present invention, crimped fibers having a torque of 30T/m or less (hereinafter, also referred to simply as "crimped fibers") are included. By including the crimped fiber in a fabric, elasticity is imparted to the fabric.

The crimped fiber contains 2 or more (preferably 2 to 5, and particularly preferably 2) types of single fibers different from each other, and thereby a novel appearance and a novel texture are obtained by the uneven appearance and texture.

In this case, the 2 or more types of single fibers preferably differ from each other in the component constituting the fiber, the cross-sectional shape of the single fiber, or the fineness of the single fiber.

Here, "different components" includes not only combinations of different types of polymers but also combinations of the same type of polymer and different components and additives of the 3 rd component. Examples of the combination include combinations of nylon and polyester, cationic dyeable polyester and cationic non-dyeable polyester, polytrimethylene terephthalate and polyethylene terephthalate, and polyesters having different titanium oxide contents (e.g., bright polyester and full-dull polyester).

Here, the crimped fiber is a composite yarn including a false-twisted crimped yarn a having a torque in the S direction and a false-twisted crimped yarn B having a torque in the Z direction, and the crimped fiber is preferably a composite yarn in which the false-twisted crimped yarn a and the false-twisted crimped yarn B include different monofilaments.

The false-twist textured yarn includes a so-called single heater (one heater) false-twist textured yarn in which a false twist is set in the 1 st heater region and a so-called second heater (second heater) false-twist textured yarn in which a torque is reduced by further introducing the textured yarn into the 2 nd heater region and performing a relaxation heat treatment. Further, depending on the twisting direction, there are false twist textured yarns having a torque in the S direction and false twist textured yarns having a torque in the Z direction. These false twist textured yarns can be used in the present invention. In particular, if the composite yarn is composed of the false twist textured yarn having the torque in the S direction and the false twist textured yarn having the torque in the Z direction, the composite yarn having a low torque can be obtained, which is preferable.

The composite yarn can be produced, for example, by the following method. That is, the yarn may be twisted by a twisting machine by passing the yarn through the 1 st roll and a heat treatment heater having a set temperature of 90 to 220 ℃ (more preferably 100 to 190 ℃) to obtain a single-heater false-twist crimped yarn, or may be further introduced into the 2 nd heater zone as necessary to be subjected to relaxation heat treatment to obtain a second-heater false-twist crimped yarn. The draw ratio in the false twist crimping process is preferably in the range of 0.8 to 1.5. For false twist number, the false twist number (T/m) is (32500/(D)^1/2) In the formula of x α, α is preferably in the range of 0.5 to 1.5 (more preferably 0.8 to 1.2). Wherein D is the total fineness (dtex) of the yarn. As the twisting device to be used, a disc type or belt type friction type twisting device is suitable because it is easy to catch a yarn and there is little yarn breakage, but a pin type twisting device may be used. Depending on the direction of twisting, the torque of the false twist textured yarn can be selected to be in the S direction or the Z direction. Next, the composite yarn is obtained by twisting 2 or more kinds of false twist textured yarns containing different types of single fibers.

The crimped fibers are preferably entangled by an interlacing process. The number of intertwining (interlacing) is preferably in the range of 1 to 70 pieces/m (more preferably 2 to 65 pieces/m). If the number is large, not only the elasticity is reduced but also the feeling of non-uniformity is insufficient, and there is a possibility that a novel appearance and a novel texture cannot be obtained.

The torque of the composite yarn thus obtained is preferably 30T/m or less (preferably 18T/m or less, more preferably 10T/m or less, and particularly preferably no torque (0T/m)). The smaller the torque, the better, and most preferably no torque (0T/m).

In the crimped fiber, the crimp ratio is preferably 2% or more (more preferably 10 to 60%). When the percentage of crimp is less than 2%, the elasticity may be reduced.

In the crimped fiber, the diameter of a single fiber called nanofiber may be 1000nm or less, and the fineness of the single fiber is preferably in the range of 0.00002 to 2.0 dtex. If the single fiber fineness is more than 2.0dtex, flexibility may be reduced.

In the crimped fiber, the total fineness (the product of the single fiber fineness and the number of filaments) is preferably in the range of 40 to 400dtex (more preferably 40 to 180 dtex).

Further, the cross-sectional shape of the single fiber of the crimped fiber may be, for example, triangular, square, cross, flat with shrinkage, H-shaped, W-shaped, or the like. In this case, from the viewpoint of flexibility of the fabric, it is preferable that the flatness of the cross section represented by the ratio B/C1 of the length B in the longitudinal center line direction of the flat cross-sectional shape to the maximum width C1 in the direction perpendicular to the longitudinal center line direction is in the range of 2 to 6 (more preferably 3.1 to 5.0). In addition, from the viewpoint of the water absorption property of the fabric, the ratio C1/C2 of the maximum value C1 to the minimum value C2 of the width is preferably in the range of 1.05 to 4.00 (more preferably 1.1 to 1.5).

The fibers constituting the crimped fibers are not particularly limited, and polyester fibers, acrylic fibers, nylon fibers, rayon fibers, acetate fibers, natural fibers such as cotton, wool, and silk, and fibers obtained by combining these fibers can be used. Polyester fibers or nylon fibers are particularly preferred. The polyester fiber includes a composite fiber containing at least a polyester component. Examples of the composite fiber include a side-by-side composite fiber, an eccentric core-sheath composite fiber, a core-sheath composite fiber, and an island-in-sea composite fiber. The nylon fiber includes nylon 6 fiber and nylon 66 fiber.

The polyester is preferably a polyester containing terephthalic acid as a main acid component and an alkylene glycol having 2 to 6 carbon atoms, that is, at least 1 selected from the group consisting of ethylene glycol, propylene glycol, butylene glycol, pentylene glycol and hexylene glycol as a main glycol component. Among them, a polyester (polyethylene terephthalate) containing ethylene glycol as a main glycol component or a polyester (polypropylene terephthalate) containing propylene glycol as a main glycol component is particularly preferable.

The polyester may have a small amount (usually 30 mol% or less) of a copolymerizable component as required. In this case, examples of the bifunctional carboxylic acid other than terephthalic acid to be used include aromatic, aliphatic and alicyclic bifunctional carboxylic acids such as isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid, diphenoxyethanedicarboxylic acid, β -hydroxyethoxybenzoic acid, p-hydroxybenzoic acid, 5-sodium sulfoisophthalate, adipic acid, sebacic acid and 1, 4-cyclohexanedicarboxylic acid. Examples of the diol compounds other than the above diols include aliphatic, alicyclic, and aromatic diol compounds such as cyclohexane-1, 4-dimethanol, neopentyl glycol, bisphenol a, and bisphenol S, and polyoxyalkylene glycols.

The above polyester can be synthesized by any method. For example, if the case of polyethylene terephthalate is explained, it can be produced by the reaction of the 1 st stage in which terephthalic acid and ethylene glycol are directly esterified, or a lower alkyl ester of terephthalic acid such as dimethyl terephthalate and ethylene glycol are subjected to transesterification, or terephthalic acid and ethylene oxide are reacted to produce ethylene glycol terephthalate and/or an oligomer thereof, and the reaction of the 2 nd stage in which the reaction product of the 1 st stage is heated under reduced pressure to cause polycondensation until a desired degree of polymerization. The polyester may be a polyester obtained by recovering a material or chemically recovering a material, or a polyester obtained by using a catalyst containing a specific phosphorus compound and titanium compound as described in Japanese patent application laid-open Nos. 2004-270097 and 2004-211268. Further, biodegradable polyesters such as polylactic acid and stereocomplex polylactic acid may be used.

Further, it is preferable that the polyester contains an ultraviolet absorber in an amount of 0.1 wt% or more (preferably 0.1 to 5.0 wt%) based on the weight of the polyester, since the fabric is imparted with ultraviolet shielding properties. As the ultraviolet absorber, benzene is exemplifiedOxazine-based organic ultraviolet absorber, benzophenone-based organic ultraviolet absorber, and benzotriazole-based organic ultraviolet absorberA linear absorber, a salicylic acid-based organic ultraviolet absorber, and the like. Among them, particularly preferred is benzo group in terms of not decomposing at the stage of spinningAn oxazine-based organic ultraviolet absorber.

As the benzeneAs the oxazine-based organic ultraviolet absorber, the organic ultraviolet absorber disclosed in Japanese patent application laid-open No. 62-11744 can be suitably exemplified. I.e. with 2-methyl-3, 1-benzoOxazin-4-one, 2-butyl-3, 1-benzoOxazin-4-ones, 2-phenyl-3, 1-benzolsOxazin-4-one, 2' -ethylidenebis (3, 1-benzoOxazin-4-one), 2' -tetramethylenebis (3, 1-benzoOxazin-4-one), 2' -p-phenylenebis (3, 1-benzoOxazin-4-one), 1,3, 5-tris (3, 1-benzoOxazin-4-keto-2-yl) benzene, 1,3, 5-tris (3, 1-benzoOxazin-4-on-2-yl) naphthalene, and the like.

Further, it is preferable that the polyester contains a matting agent (titanium dioxide) in an amount of 0.1 wt% or more (preferably 0.2 to 4.0 wt%) based on the weight of the polyester, because the permeability resistance of the fabric is improved.

The polyester may contain 1 or more of a micropore forming agent (organic sulfonic acid metal salt), a coloring inhibitor, a heat stabilizer, a flame retardant (antimony trioxide), a fluorescent brightener, a coloring pigment, an antistatic agent (sulfonic acid metal salt), a moisture absorbent (polyoxyalkylene glycol), an antibacterial agent, and other inorganic particles, as required.

The fabric of the present invention contains the crimped fiber. In this case, the crimped fiber is preferably contained in an amount of 50 wt% or more based on the weight of the fabric.

The structure of the fabric is not particularly limited, and may be any of a knitted fabric and a woven fabric. For example, a woven fabric having a woven structure such as a plain weave, a twill weave, or a satin weave, a knitted fabric having a knitted structure such as a plain weave, a interlock weave, a circular weave, a deer-point pattern, a plated weave, a single bar warp flat weave, or a half-bed weave, a nonwoven fabric, or the like can be appropriately exemplified, but the present invention is not limited thereto. The number of layers may be a single layer or a plurality of layers of 2 or more. Among them, a knitted fabric (knitted fabric) is preferable in terms of obtaining excellent elasticity. Particularly preferred are knitted fabrics having a warp or weft (circular knitting) structure.

In this case, the knitted fabric preferably has a density of 40 to 100/2.54cm in the number of courses and 30 to 60/2.54cm in the number of wales.

In the fabric of the present invention, the basis weight of the fabric is preferably 50 to 200g/m²Within the range of (1).

The fabric of the present invention can be obtained by knitting the above crimped fiber (if necessary, other fiber) by a conventional method.

Next, it is preferable to perform a dyeing process. In this case, the temperature of the dyeing process is preferably 100 to 140 ℃ (more preferably 110 to 135 ℃), and the time is preferably 5 to 40 minutes for holding the highest temperature. The knitted fabric subjected to the dyeing process is preferably subjected to dry heat final setting. In this case, the temperature of the dry heat final setting is preferably 120 to 200 ℃ (more preferably 140 to 180 ℃) and the time is preferably 1 to 3 minutes.

The fabric of the present invention is preferably subjected to water absorption processing (hydrophilizing agent application). The water absorption property is improved by subjecting the fabric to water absorption processing. As the water absorbing processing, for example, it is preferable to attach a hydrophilic agent (water absorbing processing agent) such as polyethylene glycol diacrylate, a derivative thereof, or a polyethylene terephthalate-polyethylene glycol copolymer to a fabric at 0.25 to 0.50 wt% with respect to the weight of the fabric. Examples of the water absorbing processing method include a bath processing method in which a water absorbing processing agent is mixed with a dye solution in dyeing processing, a method in which a fabric is immersed in a water absorbing processing solution and calendered by a calender before dry-heat final setting, and a coating processing method such as a gravure coating method and a screen printing method.

Further, various treatments for imparting functions such as ultraviolet shielding or an antibacterial agent, a deodorant, an insect repellent, a light storage agent, a retroreflective agent, an anion generator, and a water repellent can be additionally applied to the raising treatment which is a conventional method.

The fabric obtained in this way contains the above crimped fibers, and since the crimped fibers contain 2 or more (preferably 2 to 5, and particularly preferably 2) types of single fibers different from each other, a novel appearance and a novel texture can be obtained by the sense of unevenness of appearance and texture.

The water absorption property of the fabric, as measured by JIS L1907-19985.1.2 Bayer process, is preferably 7cm or more (more preferably 7-15 cm) on at least either of the front and back surfaces of the fabric.

The water absorption of the front and back surfaces of the fabric washed 3 times by JIS L0217-1998, 103 is preferably 8cm or more (more preferably 8 to 16cm) as measured by JIS L1907-19985.1.2 Bayer process.

Further, as the snagging resistance, it is preferable that the snagging resistance is of grade 3 or more, as measured by a saw in JIS L1058-.

In the fabric of the present invention, at the same time, the elasticity is exhibited by the crimped fiber. The elasticity is preferably 50% or more (preferably 80 to 130%) in the transverse direction as measured by JIS L1018-. Further, the transverse elastic recovery measured by JIS L1018-1990 is preferably 90% or more.

Further, according to the present invention, there is provided a textile product, which is made using the above fabric and is selected from any one of clothing, interlining, socks, abdominal bands, hats, gloves, pajamas, bedding inner covers, bedding covers, and car seat skin materials. Since the fiber product uses the above-described fabric, a novel appearance and a novel texture are exhibited by the unevenness in appearance and texture.
