[0006] According to the present invention, it is possible to provide a twisted yarn and a woven or knitted fabric thereof that can obtain an appearance with a natural surface effect. [Modes for carrying out the invention]

[0007] The embodiments of the present invention will be described in detail below. The following embodiments are merely illustrative for illustrating the present invention and are not intended to limit the present invention to these embodiments. The present invention can be implemented in various forms without departing from its spirit. In this invention, "woven or knitted fabric" refers to a woven or knitted fabric. In this invention, "cationically dyeable yarn" means yarn that can be dyed with a cationic dye. In this specification, "appearance with a natural surface effect" means an appearance with a subtle color variation and a natural slab mottling. The numerical ranges of content, various physical properties, and characteristic values ​​disclosed herein can be arbitrarily combined with their lower and upper limits to create new numerical ranges.

[0008] [Twisted yarn] The blended yarn according to this embodiment is a yarn (twisted yarn) that includes two or more false-twisted slub yarns, which include a core yarn and embellishment yarns, and which are twisted together. Each false-twist slub yarn has a core yarn with alternating slab sections where the embroidered threads are wound three times and mid-circle sections where the embroidered threads are wound once, along the longitudinal direction of the core yarn. The blended yarn includes at least two types of false-twist slub yarns. By twisting two or more false-twist slub yarns with different forms together, the irregularities of each false-twist slub yarn are mixed, making it possible to create a diverse and natural surface appearance. When a blended yarn contains two types of false-twist slub yarns, it is preferable that one false-twist slub yarn contains cationic dyeable yarn, while the other false-twist slub yarn does not. By having only one false-twist slub yarn contain cationic dyeable yarn, the cationic dyeable portion becomes visible and hidden after dyeing following the twisting process, enabling a wide range of color expression. Polyester filament is preferred as the cationic dyeable yarn. In this specification, a collection of yarns including two or more false-twisted slub yarns before twisting is also referred to as a "ply yarn" or "ply yarn strip." That is, the cross-twisted yarn of this embodiment may be a cross-twisted yarn made by twisting a ply yarn containing two or more types of false-twisted slub yarns, or it may be a cross-twisted yarn made by directly twisting two or more types of false-twisted slub yarns without plying them together.

[0009] The blended yarn only needs to contain two or more types of false-twisted slub yarns. It may be a yarn (twisted yarn) obtained by twisting only two or more types of false-twisted slub yarns, or it may be a yarn (twisted yarn) obtained by twisting two or more types of false-twisted slub yarns with other yarns. Other types of yarn include, for example, filament yarn, false-twist yarn, and spun yarn.

[0010] The configuration of the false-twist slub yarn containing cationic dyeable yarn is preferably one core yarn and two embellishing yarns (i), or one core yarn, two swirl yarns, and one embellishing yarn (ii). By using either configuration (i) or configuration (ii) for the false-twist slub yarn containing cationic dyeable yarn, natural color expression becomes possible when cationic dyeing is performed. The coiled yarn is a yarn wound around a core yarn. The coiled yarn is preferably wound around the core yarn in a helical shape in the longitudinal direction of the core yarn. The coiled yarn can be obtained by supplying it excessively so that the yarn length ratio to the core yarn is 5% or more and 40% or less (the overfeed is 1.05 to 1.40). In addition, when the structure of the false-twisted slab yarn containing cation-dyeable yarn is Structure (ii), the coiled yarn is wound around the core yarn in the slab part and the middle part of the path, and does not have a three-ply wound slab part.

[0011] The cation-dyeable yarn may be any of the core yarn, the fancy yarn, and the coiled yarn, but it is preferable that at least one of the fancy yarn and the coiled yarn is a cation-dyeable yarn. In particular, when the structure of the false-twisted slab yarn containing cation-dyeable yarn is Structure (i), it is preferable that the fancy yarn is a cation-dyeable yarn, and from the viewpoint of enabling a complex color tone feeling, it is more preferable that one of the two fancy yarns is a cation-dyeable yarn. When the structure of the false-twisted slab yarn containing cation-dyeable yarn is Structure (ii), it is preferable that at least one of the fancy yarn and the coiled yarn is a cation-dyeable yarn, and from the viewpoint of enabling a complex color tone feeling, it is more preferable that the coiled yarn is a cation-dyeable yarn, and it is even more preferable that one of the two coiled yarns is a cation-dyeable yarn. As the false-twisted slab yarn containing cation-dyeable yarn, from the viewpoint of enabling a more complex color tone feeling, the false-twisted slab yarn of Structure (i) is preferable, and among them, particularly, the false-twisted slab yarn in which one of the two fancy yarns is a cation-dyeable yarn is more preferable. Examples of the yarn other than the cation-dyeable yarn include polyester fiber, cellulose fiber, nylon fiber, and the like.

[0012] At least one type of the false-twisted slab yarn constituting the cross-twisted yarn is preferably a false-twisted slab yarn in which the thickness of the slab part is 1.8 times or more the thickness of the middle part of the path, and more preferably 1.9 times or more. When the thickness of the slab part is 1.8 times or more the thickness of the middle part of the path, the slab mottle feeling is emphasized, and a more natural surface feeling becomes possible. The thickness of the slab part is preferably 2.6 times or less the thickness of the middle part of the path. The thickness of the slab part is calculated by adding the fineness of the core yarn and three times (triple) the fineness of the fancy yarn. The thickness of the middle part of the path is calculated by adding the fineness of the core yarn and the fineness of the fancy yarn. When the false-twist slab processed yarn contains a wrapped yarn, the thickness of the slab part is calculated by adding the fineness of the core yarn and the overfeed of the wrapped part to three times (triple) the fineness of the fancy yarn. The thickness of the guiding middle part is calculated by adding the fineness of the core yarn and the overfeed of the wrapped part to the fineness of the fancy yarn.

[0013] The ply yarn is preferably composed of two types of false-twist slab processed yarns with a difference in hot water dimensional change rate of 0.5% or more. When the difference in hot water dimensional change rate of the two types of false-twist slab processed yarns is 0.5% or more, unevenness occurs in the knitted or woven fabric. The difference in hot water dimensional change rate between the two types of false-twist slab processed yarns is more preferably 1.0% or more, further preferably 2.0% or more, and preferably 6.0% or less, more preferably 5.0% or less.

[0014] At least one type of the false-twist slab processed yarn constituting the ply yarn preferably contains polyester shick and sin yarn in the core yarn. Since the polyester shick and sin yarn produces a shade difference between the shick part and the sin part when dyed with a disperse dye, a more complex color tone is obtained. By including the polyester shick and sin yarn in the core yarn, a shade difference occurs during the dyeing process, enabling a more complex color tone expression. Note that the surface, cross-sectional shape, luster, etc. of the fiber are not particularly limited, and they may be arbitrarily selected in consideration of the obtained knitted or woven fabric expression.

[0015] At least one type of the false-twist slab processed yarn constituting the ply yarn preferably contains a polyester conjugate yarn in the core yarn. By including the polyester conjugate yarn in the core yarn, an effect of imparting stretchability to the knitted or woven fabric can be expected. Note that the surface, cross-sectional shape, luster, etc. of the fiber are not particularly limited, and they may be arbitrarily selected in consideration of the obtained knitted or woven fabric expression.

[0016] Preferably, at least one of the false-twist slub yarns that make up the interwoven yarn contains a cellulose-based multifilament yarn in the flower filament. When the structure of the false-twist slub yarn is structure (ii), it is preferable that at least one of the swirling yarn and the flower yarn contains a cellulose-based multifilament yarn. The inclusion of cellulose-based multifilaments in the swirling yarn or floral yarn maintains moisture absorption, thereby imparting a cool and refreshing feel to woven or knitted fabrics.

[0017] Examples of cellulose-based multifilament yarns include acetate, rayon, cupro (copper ammonia rayon), and lyocell. Among these, it is preferable to use one or more selected from acetate, rayon, and cupro (copper ammonia rayon). Acetate fibers, in particular, are suitable as cellulose-based multifilament yarns because they possess excellent color development due to their low refractive index, a luxurious luster, a soft and cool texture derived from cellulose, and heat-setting properties. Furthermore, there are no particular limitations on the surface, cross-sectional shape, or luster of the fibers; they can be arbitrarily selected considering the resulting woven or knitted fabric appearance.

[0018] The twist coefficient of the blended yarn is preferably 5000 or more and 15000 or less, more preferably 6000 or more and 13000 or less, and even more preferably 7000 or more and 10000 or less. If the twist coefficient is above the lower limit above, a dry and crisp texture is easily obtained, and if it is below the upper limit above, a voluminous texture is easily obtained. The twist coefficient of the twisted yarn can be calculated using the following formula (1). Twist coefficient = T√D ···(1) In equation (1), "T" is the number of twists (unit: t / m) and "D" is the total fineness (unit: dtex).

[0019] The average total fineness of the blended yarn is preferably 300 dtex or more and 700 dtex or less, more preferably 350 dtex or more and 650 dtex or less, and even more preferably 400 dtex or more and 600 dtex or less. If the average total fineness is above the lower limit above, a natural and expressive appearance is easily obtained, and if it is below the upper limit above, the fineness will not be too thick and will be suitable for clothing.

[0020] The blended yarn is obtained by combining two or more of the above-mentioned false-twist slub yarns to form a plied yarn, and then twisting the resulting plied yarn, or by directly twisting two or more of the above-mentioned false-twist slub yarns without forming a plied yarn. In addition to two or more false-twist slub yarns, other yarns mentioned above may also be used in combination.

[0021] [Woven and knitted fabrics] The woven or knitted fabric of this embodiment includes the twisted yarn of the present invention as described above. The content of twisted yarn relative to the total mass of the woven or knitted fabric, i.e., the blending rate of twisted yarn, is preferably 30% by mass or more, more preferably 40% by mass or more, even more preferably 50% by mass or more, and may also be 100% by mass. If the blending rate of twisted yarn is above the lower limit of the above value, a rich and natural appearance can be obtained. Furthermore, if the woven or knitted fabric is a woven fabric, it is preferable to include the blended yarn of the present invention in at least the weft yarn, from the viewpoint of obtaining a richer and more natural appearance. The weft yarn may consist only of the blended yarn of the present invention, or it may further include yarns other than the blended yarn of the present invention. The warp yarn may or may not include the blended yarn of the present invention, but it is preferable that it includes the blended yarn of the present invention.

[0022] The woven or knitted fabric of this embodiment may be treated with a crinkling process. The method of wrinkle processing is not particularly limited; it can be arbitrarily selected based on the desired woven or knitted fabric expression, such as packing wrinkles by feeding more fabric than usual into a liquid flow dyeing machine, or wrinkle processing using airflow such as tumblers or airflow after dyeing. By applying wrinkle processing, a more natural appearance and a puffy feel due to the crumpling effect can be obtained. [Examples]

[0023] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples as long as it does not exceed the spirit of the invention, and various modifications are possible as long as they do not depart from the spirit of the invention. The measurement and evaluation methods used in the examples are as follows:

[0030] <False twist slub yarn D> Except for using a side-by-site type polyester composite multifilament (Toray Operontex's "Type T400", 56dtex24f) consisting of polyethylene terephthalate and polytrimethylene terephthalate components as the core yarn, false twisting was performed in the same manner as false twist slub yarn B, resulting in a false twist slub yarn D in which slub sections with flower filaments (1) and (2) each wrapped three times and middle sections with flower filaments (1) and (2) each wrapped once are alternately formed in the longitudinal direction of the core yarn, with an average fineness of 288dtex, a triacetate multifilament content of 55% by mass, a cationic dyeable polyester multifilament content of 23% by mass, and a polyester multifilament content of 22% by mass. Table 1 shows the composition, average fineness, and hot water dimensional change rate of false-twist slub yarn D.

[0031] [Table 1]

[0032] [Example 1] False-twisted slub yarn A and false-twisted slub yarn B were joined together and then twisted using a double twister with a twist direction Z and a twist count of 300 T / M to obtain a blended yarn X with an average total fineness of 560 dtex. Using a blended yarn X as the warp and weft threads, a plain weave fabric was produced with a warp density of 35 threads / inch and a weft density of 30 threads / inch. After scouring, the fabric was dyed at 120°C using a jet dyeing machine with a cationic dye in brown and a disperse dye in beige, resulting in a fabric with a warp density of 41 threads / inch and a weft density of 31 threads / inch. The resulting fabric had a design effect due to the mottled texture of the false-twist slub yarn, as well as a natural, nep-like appearance reminiscent of linen husks, achieved through the dyeing of false-twist slub yarn B with disperse and cationic dyes, and its combination with false-twist slub yarn A. Furthermore, while casual, it possessed a moderate sheen, giving it a sense of luxury. Details of the blended yarns and fabrics, as well as the results regarding their design, are shown in Table 2 or Table 3.

[0033] [Example 2] A twisted yarn X was obtained in the same manner as in Example 1. A five-ply satin fabric was woven using triacetate multifilament (manufactured by Mitsubishi Chemical Corporation, 84dtex20f) as the warp yarn with a twist direction of S and a twist count of 350T / M, and a blended yarn X as the weft yarn, resulting in a warp density of 222 threads / inch and a weft density of 57 threads / inch. After scouring, the fabric was dyed at 120°C using a jet dyeing machine with a cationic dye in brown and a disperse dye in beige, resulting in a fabric with a warp density of 242 threads / inch and a weft density of 63 threads / inch. The resulting fabric had a design effect due to the mottled texture of the false-twist slub yarn, as well as a natural, nep-like appearance reminiscent of linen husks, achieved through the dyeing of false-twist slub yarn B with disperse and cationic dyes, and its combination with false-twist slub yarn A. Furthermore, while casual, it possessed a moderate sheen, giving it a sense of luxury. Details of the blended yarns and fabrics, as well as the results regarding their design, are shown in Table 2 or Table 3.

[0034] [Example 3] False-twisted slub yarn A and false-twisted slub yarn C were joined together and then twisted using a double twister with a twist direction Z and a twist count of 300 T / M to obtain a blended yarn Y with an average total fineness of 550 dtex. Using a blended yarn Y as both the warp and weft threads, a plain weave fabric was produced with a warp density of 32 threads / inch and a weft density of 28 threads / inch. After scouring, the fabric was dyed at 120°C using a jet dyeing machine with a cationic dye in brown and a disperse dye in beige, resulting in a fabric with a warp density of 43 threads / inch and a weft density of 37 threads / inch. The resulting fabric exhibited a design effect due to the mottled texture of the false-twist slub yarn, as well as a delicate, contrasting color dyeing effect resulting from the use of disperse and cationic dyes on false-twist slub yarn C and its combination with false-twist slub yarn A. It also had a natural, nep-like appearance reminiscent of linen slubs. Furthermore, it was a functional fabric with stretch in both the warp and weft. Details of the blended yarns and fabrics, as well as the results regarding their design, are shown in Table 2 or Table 3.

[0035] [Example 4] False-twisted slub yarn A and false-twisted slub yarn D were joined together and then twisted using a double twister with a twist direction Z and a twist count of 300 T / M to obtain a blended yarn Z with an average total fineness of 560 dtex. Using a blended yarn Z as both the warp and weft threads, a plain weave fabric was produced with a warp density of 31 threads / inch and a weft density of 28 threads / inch. After scouring, the fabric was dyed at 120°C using a jet dyeing machine with a cationic dye in brown and a disperse dye in beige, resulting in a fabric with a warp density of 42 threads / inch and a weft density of 34 threads / inch. The resulting fabric had a design effect due to the mottled texture of the false-twist slub yarn, as well as a natural, nep-like appearance reminiscent of linen husks, achieved through the dyeing of false-twist slub yarn D with disperse and cationic dyes, and its combination with false-twist slub yarn A. Furthermore, it was a functional fabric with stretch in both the warp and weft. Details of the blended yarns and fabrics, as well as the results regarding their design, are shown in Table 2 or Table 3.

[0036] [Comparative Example 1] Two false-twist slub yarns C were joined together and plied, then twisted using a double twister with a twist direction Z and a twist count of 300 T / M to obtain a blended yarn H with an average total fineness of 560 dtex. Using a blended yarn H as the warp and weft threads, a plain weave fabric was woven with a warp density of 31 threads / inch and a weft density of 28 threads / inch. After scouring, the fabric was dyed at 120°C using a jet dyeing machine with a cationic dye in brown and a disperse dye in beige, resulting in a fabric with a warp density of 46 threads / inch and a weft density of 38 threads / inch. The resulting fabric exhibited a degree of color separation using disperse and cationic dyes, but the color separation was uniform. Furthermore, it lacked texture and three-dimensionality, and a natural surface texture was not achieved. Details of the blended yarns and fabrics, as well as the results regarding their design, are shown in Table 2 or Table 3.

[0037] [Table 2]

[0038] [Table 3]
