[0009] According to the present invention, it is possible to provide a composite processed yarn which can produce a woven or knitted fabric having a luxurious appearance and a fluffy, squeaky feel that is comfortable to the touch, and a woven or knitted fabric containing the composite processed yarn. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An embodiment of the composite textured yarn and a woven or knitted fabric containing the composite textured yarn of the present invention will be described. It should be noted that the present embodiment is specifically described to allow a better understanding of the gist of the invention, and does not limit the present invention unless otherwise specified.

[0011] In the present invention, the term "woven or knitted fabric" refers to a woven fabric or a knitted fabric. In addition, the symbol "~" indicating a range of numerical values ​​means that the numerical values ​​before and after it are included as the lower limit and upper limit.

[0012] [Composite textured yarn] The composite textured yarn of this embodiment contains cellulosic filaments having a single fiber fineness of 0.7 to 2.5 dtex and a titanium oxide content of 0.1 to 2 mass %, and polyester filaments having a boiling water shrinkage rate of 15 to 30%. The boiling water shrinkage rate is defined by the skein dimensional change rate in JIS L1013:2010 "Testing method for chemical fiber filament yarn."

[0013] If the single fiber fineness of the cellulose filament is 0.7 dtex or more, the fuzz and knots of the composite textured yarn are suppressed, and the productivity of the woven and knitted fabric is stabilized. If the single fiber fineness of the cellulose filament is 2.5 dtex or less, a woven or knitted fabric with a squeaky feel can be obtained. From these viewpoints, the single fiber fineness of the cellulose filament is preferably 1.8 dtex or less, and more preferably 1.2 dtex or less.

[0014] When the titanium oxide content of the cellulose filaments is 0.1 to 2 mass%, a woven or knitted fabric having a comfortable, squeaky feel can be obtained. When the titanium oxide content of the cellulose filaments is 2 mass% or less, the generation of fuzz caused by metal wear during the production of the woven or knitted fabric is suppressed, and the productivity and quality of the woven or knitted fabric are stabilized. From these viewpoints, it is more preferable that the titanium oxide content of the cellulose filaments is 0.4 to 1.6 mass%.

[0015] If the boiling water shrinkage rate of the polyester filament is 15% or more, a woven or knitted fabric with a fluffy feel can be obtained due to the difference in shrinkage between the polyester filament and the cellulosic filament. If the boiling water shrinkage rate of the polyester filament is 30% or less, fluffiness is suppressed, and a woven or knitted fabric with a squeaky, comfortable feel can be obtained. From these viewpoints, the boiling water shrinkage rate of the polyester filament is preferably 17 to 25%. Incidentally, "fluffiness" means that the material becomes bulky and soft.

[0016] In the composite textured yarn of the present embodiment, the boiling water shrinkage of the cellulosic filaments is preferably 0 to 10%. Furthermore, the difference in shrinkage between the polyester filaments and the cellulosic filaments is preferably 7% or more, and more preferably 10% or more, from the viewpoint of obtaining a woven or knitted fabric with a fluffy feel.

[0017] In the composite textured yarn of the present embodiment, the cellulose filaments and the polyester filaments are preferably air entangled. That is, the composite textured yarn of the present embodiment is preferably an air entangled yarn of the cellulose filaments and the polyester filaments. By being air entangled, it is possible to obtain a glossy and fluffy texture while suppressing the generation of fuzz. Air entanglement is a process in which air is blown onto the fibers to entangle the fibers with each other. Examples of air entanglement include interlace processing and taslan processing.

[0018] In the composite textured yarn of the present embodiment, the air entanglement is preferably an interlace process. That is, in the composite textured yarn of the present embodiment, the air entanglement is preferably an interlace process. If the air entanglement is an interlace process, a luxurious glossy feel and a fluffy texture can be obtained while suppressing fuzzing. The interlacing process is a process in which the filaments are entangled by applying air pressure perpendicular to the direction of travel of the filaments.

[0019] In the composite textured yarn of the present embodiment, the cellulosic filaments preferably have a single fiber fineness of 0.7 to 1.2 dtex. By making the single fiber fineness 0.7 dtex or more, fuzz and knots of the composite textured yarn are suppressed, and productivity in weaving and knitting is stabilized. By making the single fiber fineness 1.2 dtex or less, the fluffy feeling can be further improved. From this viewpoint, the single fiber fineness is more preferably 1.1 dtex or less, and even more preferably 1.0 dtex or less.

[0020] The composite textured yarn of this embodiment preferably has a total fineness of 70 to 170 dtex. If the total fineness is 70 dtex or more, a fluffy feel is obtained and the weaving and knitting properties are stable. If the total fineness is 170 dtex or less, a delicate and luxurious product is obtained. From these viewpoints, the total fineness is more preferably 85 to 130 dtex.

[0021] In the composite textured yarn of the present embodiment, the cellulose filament is preferably acetate, rayon, cupra or lyocell. Among them, acetate fiber is more preferable from the viewpoints of excellent color development due to a low refractive index, luxurious glossiness, soft and refreshing texture derived from cellulose, and heat setting property. The surface, cross-sectional shape, luster, etc. of the fiber are not particularly limited, and may be arbitrarily selected in consideration of the expression of the resulting woven or knitted fabric.

[0022] The composite textured yarn of the present embodiment preferably has a polyester filament content of 10 to 50% by mass. If the polyester filament content is 10% by mass or more, the strength of the woven or knitted fabric can be increased, and a fluffy texture due to the difference in shrinkage with the cellulosic filament can be obtained. If the polyester filament content is 50% by mass or less, the waxy texture specific to synthetic fibers is reduced, and a woven or knitted fabric with a squeaky, comfortable feel can be obtained.

[0023] The polyester filaments are not particularly limited in terms of production method, type, cross-sectional shape, surface shape, luster, dye-adhering properties, etc., and may be arbitrarily selected in consideration of the woven or knitted fabric to be obtained. Examples of polyesters constituting the polyester filaments include polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT).

[0024] The single fiber fineness of the polyester filament is preferably 0.8 to 3 dtex, and more preferably 1 to 2.5 dtex. If the single fiber fineness of the polyester filament is 0.8 dtex or more, the fabric will not be too soft and will have a firm texture. If the single fiber fineness of the polyester filament is 3 dtex or less, the woven or knitted fabric will not be too stiff.

[0025] The composite processed yarn of this embodiment contains cellulose-based filaments having a single fiber fineness of 0.7 to 2.5 dtex and a titanium oxide content of 0.1 to 2 mass%, and polyester filaments having a boiling water shrinkage rate of 15 to 30%, resulting in a woven or knitted fabric with a luxurious appearance and a fluffy, squeaky feel that is comfortable to the touch.

[0026] [Woven and knitted fabrics] The woven or knitted fabric of the present embodiment contains the composite textured yarn, and the content of the composite textured yarn is 30 to 100 mass %. When the content of the composite textured yarn in the woven or knitted fabric is 30% by mass or more, a woven or knitted fabric having a squeaky feel and a comfortable texture can be obtained. From this viewpoint, the content of the composite textured yarn is preferably 50% by mass or more, and more preferably 70% by mass or more.

[0027] The woven or knitted fabric of this embodiment preferably contains the composite textured yarn as the warp yarn and a false twist textured yarn or a conjugate yarn as the weft yarn. By including the composite textured yarn in the warp yarn, a sense of volume and squeaking can be easily obtained, and by including false twist textured yarn or conjugate yarn in the weft yarn, a sense of volume and rebound can be further easily obtained.

[0028] The woven or knitted fabric of the present embodiment preferably further contains cellulosic fibers in the weft. The cellulosic fiber is cotton, acetate, rayon, cupra or lyocell, and among them, cotton is more preferable from the viewpoint of water absorbency. In addition, the cellulose fibers are preferably arranged alternately with false twisted yarn or conjugated yarn. By arranging a voluminous yarn such as false twisted yarn or conjugated yarn alternately with non-voluminous cellulose fibers, the woven or knitted fabric is more likely to have a voluminous feel.

[0029] In the woven or knitted fabric of this embodiment, the cellulose-based fiber of the weft preferably has a titanium oxide content of 0.1 to 2% by mass. If the titanium oxide content is 0.1% by mass or more, a woven or knitted fabric having a comfortable feel with a squeaky texture can be obtained. If the titanium oxide content is 2% by mass or less, the generation of fuzz or the like due to metal wear during the production of the woven or knitted fabric is suppressed, and the productivity and quality of the woven or knitted fabric are stabilized. If a cellulose-based fiber containing titanium oxide is used for the weft, a squeaky texture can be easily obtained.

[0030] The woven or knitted fabric of this embodiment preferably includes the composite textured yarn in the warp and a double-twisted yarn of a cellulosic filament having a titanium oxide content of 0.1 to 2% by mass and a false twist textured yarn or a conjugate yarn in the weft. By including the double-twisted yarn, a fluffy feel and a squeaky feel can be easily obtained.

[0031] The content of the cellulose filaments in the doubled and twisted yarn is preferably 50 to 80% by mass, more preferably 55 to 75% by mass. If the content of the cellulose filaments is 50% by mass or more, a smooth and pleasant texture is easily obtained. If the content of the cellulose filaments is 80% by mass or less, a fluffy feel due to false twisting or conjugated yarn is easily obtained.

[0032] The woven or knitted fabric of the present embodiment is preferably subjected to at least one of a crinkling finish and a nap raising finish. The method of creping is not particularly limited, and may be selected from among various methods taking into consideration the desired expression of the woven or knitted fabric, such as stuffing creping, which is achieved by putting a larger amount of fabric than usual into a liquid flow dyeing machine, or creping using air currents such as a tumbler or airflow after dyeing. The creping process provides a natural appearance and a fuller feel due to the kneading effect.

[0033] The method of the nap raising process is not particularly limited, and may be selected from among methods such as raising with sandpaper or cardboard cloth, taking into consideration the desired expression of the woven or knitted fabric. The nap raising process can provide a very delicate feeling of squeaking and a feeling of fullness.

[0034] When the woven or knitted fabric of the present embodiment is a woven fabric, the weave of the fabric is not particularly limited. Examples of the weave include plain weave, satin weave, twill weave, warp double weave, plain double weave, and the like. When the woven or knitted fabric of the present embodiment is a knitted fabric, the knitted fabric structure is not particularly limited. Examples of knitted fabrics include plain jersey, pique, smooth, ponte roma, and mock lody.

[0035] When weaving or knitting the woven or knitted fabric of this embodiment, a known weaving method or knitting method can be used.

[0036] The woven or knitted fabric of this embodiment contains the composite processed yarn, and since the content of the composite processed yarn is 30 to 100% by mass, a woven or knitted fabric is obtained that has a luxurious appearance and a fluffy, squeaky feel that is comfortable to the touch. EXAMPLES

[0037] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to the following examples. The appearance and texture of the examples and comparative examples were evaluated by five experts in the art.

[0038] Example 1 A composite textured yarn was produced by interlacing cellulose triacetate filaments (TAD66T80, manufactured by Mitsubishi Chemical Corporation, dull 66 dtex / 80 filament (f), single fiber fineness 0.8 dtex, titanium oxide content 0.8% by mass, chrysanthemum cross section, moisture content 3.5%) and polyester filaments (PESD33T24H212, manufactured by Mitsubishi Chemical Corporation, semi-dull 33 dtex / 24f H212, titanium oxide content 0.4% by mass, round cross section, high shrinkage type with shrinkage rate of 17%). In addition, cellulose triacetate filaments (TAB66T40, manufactured by Mitsubishi Chemical Corporation, bright 66 dtex / 40 f, chrysanthemum cross section, moisture content 3.5%) and polyester filaments (PESD56T36 false twist textured yarn, manufactured by Mitsubishi Chemical Corporation, semi-dull 56 dtex / 36 f, titanium oxide content 0.4% by mass, triangular cross section) were aligned and twisted 1,800 times / m in the direction opposite to the burning direction of the false twist texture to produce S-direction twisted yarn A and Z-direction twisted yarn A. The composite processed yarn was used as the warp yarn, and the weft yarn was made of a plain weave fabric in which two of the S-direction twisted yarns A and two of the Z-direction twisted yarns A were alternately woven. The resulting grey woven fabric was dyed pale blue with a disperse dye in a conventional manner and finished to give a woven fabric having a finished warp density of 170 threads / 2.54 cm and a finished weft density of 77 threads / 2.54 cm. The obtained woven fabric had a fluffy feel as well as a unique texture with a squeaky feel and moderate drapeability, and had a smooth and comfortable feel derived from cellulosic fibers.

[0039] Example 2 The same dyeing and finishing process as in Example 1 was carried out using the grey fabric of Example 1, except that a wrinkle treatment was applied in a conventional manner. The obtained woven fabric had a fluffy feel, a characteristic texture with a squeaky feeling, and moderate drapeability, and had a smooth and comfortable feel derived from cellulosic fibers. In addition, the wrinkle processing gave it a natural look, and the fabric had a luxurious, casual feel.

[0040] Example 3 The cellulose triacetate filament used in Example 1 (TAD66T80, manufactured by Mitsubishi Chemical Corporation, dull 66 dtex / 80 f, chrysanthemum cross section, moisture content 3.5%) and polyester filament (PESD33T12V210, manufactured by Mitsubishi Chemical Corporation, semi-dull 33 dtex / 12 f, side-by-side conjugate yarn, shrinkage rate 6%, titanium oxide content 0.4% by mass) were aligned and twisted at 1,400 times / m to produce S-direction plied yarn and Z-direction plied yarn B. The composite processed yarn produced in Example 1 was used as the warp yarn, and the weft yarn was made of a plain weave fabric in which one S-direction twisted yarn B and one Z-direction twisted yarn B were alternately woven. The resulting grey woven fabric was dyed pale blue with a disperse dye in a conventional manner and finished to give a woven fabric with a finished warp density of 130 threads / 2.54 cm and a finished weft density of 76 threads / 2.54 cm. The resulting woven fabric, though thin, had a fluffy feel, a bouncy feel, a characteristic squeaking feel and a moderate degree of creaking property, and had a smooth, comfortable feel derived from cellulosic fibers.

[0041] Example 4 The composite processed yarn produced in Example 1 was used as the warp yarn, and the weft yarn was made of S-directional twisted yarn B, 80-count cotton yarn, Z-directional twisted yarn B, and 80-count cotton yarn, repeatedly woven in that order, to produce a plain weave fabric. The obtained woven fabric was paper-raised before dyeing, dyed pale blue with disperse and reactive dyes in a conventional manner, and finished. After finishing, the fabric was wrinkled in a tumbler to obtain a woven fabric with a finished warp density of 120 threads / 2.54 cm and a finished weft density of 81 threads / 2.54 cm. The fabric obtained had a unique texture that was fluffy and bouncy, as well as very soft to the touch and had a squeaky feel, and had a smooth and comfortable feel derived from cellulosic fibers. In addition, the interweaving with cotton and the crinkling process using a tumbler gave it a natural look, resulting in a fabric with a luxurious, casual feel.

[0042] Example 5 The composite textured yarn produced in Example 1 was used for the warp yarn, and a polyester filament (PE84T48 PET / PBT false twist textured yarn, Toray Industries, semi-dull 84 dtex / 48 f, side-by-side conjugate yarn of polyester and polybutylene) and a 60-count cotton yarn were used for the weft yarn, with one yarn alternately woven to create a 2 / 2 twill weave fabric. The obtained woven fabric was paper-raised before dyeing, dyed pale blue with disperse and reactive dyes in a conventional manner, and finished. After finishing, it was wrinkled in a tumbler to obtain a woven fabric with a finished warp density of 210 threads / 2.54 cm and a finished weft density of 136 threads / 2.54 cm. The obtained woven fabric had a unique texture that was fluffy, very soft to the touch, and had a squeaky feel, and had a smooth and comfortable feel derived from cellulosic fibers.It also had moderate stretchability in the weft direction, making it comfortable to wear.

[0043] Example 6 The composite processed yarn produced in Example 1 was used as the warp yarn, and a slub processed yarn consisting of triacetate filaments and polyester filaments (manufactured by Mitsubishi Chemical Corporation, product name ELB1726 283dtex / 77f, 63% triacetate, 37% polyester (including 16% cationic dyeable polyester)) was used as the weft yarn to produce a 2 / 2 twill weave fabric. The obtained grey fabric was dyed beige with disperse dye and brown with cationic dye in a conventional manner, and then finished. After finishing, the fabric was tumbled to obtain a fabric with a finished warp density of 165 threads / 2.54 cm and a finished weft density of 72 threads / 2.54 cm. The resulting woven fabric had a fluffy feel, a unique texture with a squeaky feel, and moderate drape properties, and the effect of the slub-textured weft yarn gave it a linen-like appearance.

[0044] Example 7 Cellulose triacetate filament (TAB110T26, Mitsubishi Chemical Corporation, bright 110 dtex / 26 f, chrysanthemum cross section, moisture content 3.5%) and polyester monofilament (PESD22T1, Toray Industries, semi-dull 22 dtex / 1 f) were aligned and twisted at 900 turns / m to produce S-direction ply-twisted yarn C and Z-direction ply-twisted yarn C. A satin-textured woven fabric was produced using the composite textured yarn produced in Example 1 as the warp yarn and alternating S-directional ply-twisted yarn C and Z-directional ply-twisted yarn C as the weft yarn. The resulting woven fabric was dyed pale blue with a disperse dye by a conventional method and finished to produce a woven fabric with a finished warp density of 182 threads / 2.54 cm and a finished weft density of 116 threads / 2.54 cm. The obtained woven fabric had a fluffy feel as well as a unique texture with a squeaky feel, moderate firmness and bounce, and had a refreshing and comfortable feel derived from cellulosic fibers.

[0045] (Comparative Example) A composite textured yarn was produced by interlacing cellulose triacetate filaments (TAB50T34, manufactured by Mitsubishi Chemical Corporation, bright 50 dtex / 34 f, single fiber fineness 1.5 dtex, oval cross section, moisture content 3.5%) and polyester filaments (PESD33T24H212, manufactured by Mitsubishi Chemical Corporation, semi-dull 33 dtex / 24 f H212, round cross section, shrinkage rate 17%). The composite processed yarn was used as the warp yarn, and the twisted yarn A used in Example 1 was used as the weft yarn to produce a plain weave fabric in which two yarns were woven alternately in the S direction and the Z direction. The resulting grey woven fabric was dyed pale blue with a disperse dye in a conventional manner and finished to give a woven fabric with a finished warp density of 162 threads / 2.54 cm and a finished weft density of 84 threads / 2.54 cm. The resulting woven fabric had a fluffy feel and a refreshing, comfortable texture inherent to the cellulosic fibers, but did not have a squeaky texture.

[0046] Table 1 shows the configurations of the warp and weft yarns, composite textured yarns, fabric structures, and whether the fabrics were processed or not used in the examples and comparative examples.
