Problems solved by technology

However, the stretchability of the 100% cashmere fabric obtained by this method is insufficient, and the second yarn needs to be removed with acid, and the deterioration of the remaining yarn is likely to occur.

Embodiment 1

[0111] (1) (i) 20 counts of 100% cotton spun yarns (manufactured by Tsuzuki Bosho Co., Ltd., "TS20 single yarn") with 600 twists / m (Z twist) were prepared as spun yarns. The number of twists T=15.24 times per 2.54cm of the spun yarn, count S=20, by the formula: K = ( T / S ) The calculated twist coefficient K is 15.24 / 20 = 15.24 / 4.47 = 3.24 .

[0112] (ii) Polyvinyl alcohol multifilament (56dtex) (filament dissolved in water at 80°C) (manufactured by Kuraray, "water-soluble vinylon") was prepared as a water-soluble yarn.

[0113] (2) Supply one spun yarn and one water-soluble yarn prepared in (1) above to a two-for-one twister (manufactured by Murata Machinery Co., Ltd., "36M"). (S twist) is twisted to produce a composite twisted yarn [ratio (B / A) of the twist numb...

Embodiment 2

[0118] (1) use 40 cotton double-ply yarns as warp yarns, use the composite twisted yarn obtained in embodiment 1 (2) as weft yarns, weave into the plain weave gray cloth (plain weave) of warp 25 / cm, latitude 20 / cm The blending ratio of composite twisted yarn in gray cloth is 40%). During the weaving process, the above-mentioned weaving process is carried out without sizing the warp yarns, and there is no problem such as thread breakage, and plain fabrics can be woven or knitted at high speed, and the weaving mass productivity is excellent (weaving speed 0.1m / min).

[0119] (2) Soak the plain gray cloth obtained in the above (1) in hot water at 80°C for 30 minutes (bath ratio=1:10), dissolve and remove the water-soluble yarn in the composite twisted yarn forming the weft yarn of the gray cloth, Next, the fabric was taken out from the water, and dried at 150° C. for 2 minutes. The elongation in the warp and weft directions of the gray cloth thus obtained was measured according ...

Embodiment 3

[0121] (1) (i) Prepare 40 counts of 100% cotton spun yarn (manufactured by Tsuzuki Bosho Co., Ltd., "TS40 single yarn") with a twist number of 800 times / m (Z twist), and supply two pieces of the spun yarn A two-for-one twister (manufactured by Murata Machinery Co., Ltd., "36M") twisted at 600 times / m (S twist) to produce a double-ply yarn.

[0122] (ii) A polyvinyl alcohol multifilament (56dtex) (a yarn dissolved in 80° C. water (manufactured by Kuraray Co., Ltd.), “water-soluble vinylon”) was prepared as a water-soluble yarn.

[0123] (2) The two-ply yarn (spun yarn) and water-soluble yarn prepared in (1) above are supplied to a two-for-one twister (manufactured by Murata Machinery Co., Ltd., "36M"), and the number of twists (double twist) is 1000 times. / m (Z twist) is twisted to produce a composite twisted yarn [the ratio (B / A) of the twist number B of the composite twisted yarn to the twist number A of the spun yarn = about 1.67].

[0124] (3) Cut a yarn of a specified le...

Abstract

A yarn which has a high tenacity and which dose not cause troubles such as breaking even when woven or knitted on a high-speed weaving or kitting machine and can give a woven or kitted fabric or cloth having high stretchability. A composite twist yarn obtained by intertwisting at least a spun yarn and a water-soluble yarn, in which the direction of twist of the composite twist yarn is opposite tothat of the spun yarn and which satisfies the following requirement (i) or (ii): (i) the twist number of the composite twist yarn is 1.3 to 3 times that of the spun yarn and the spun yarn / water soluble yarn weight ratio is 20 / 80 to 98 / 2, and (ii) the composite twist yarn further comprises an elastic yarn (2) stretched 2- to 5-fold in a state intertwisted with the above two yarns; and the twist number of the composite twist yarn is 0.3 to 3 times that of the spun yarn, while the weight ratio of the spun yarn (1) to the elastic yarn (2) is 50 / 50 to 99.9 / 0.1 and the weight ratio of the sum totalof the spun yarn (1) and the elastic yarn (2) to the water-soluble yarn (3) is 30 / 70 to 99 / 1.

Description

technical field [0001] The present invention relates to a composite twisted yarn obtained by twisting at least a spun yarn and a water-soluble yarn and a method for producing the same, as well as a woven or knit or knitted fabric or fabric and its production method using the composite twisted yarn. Production method. Background technique [0002] Various studies have been made to impart stretchability to woven or knitted fabrics using spun yarns. For example, woven or knitted fabrics made of composite yarns, wherein the composite yarns are composed of spun yarns and polyurethane elastic yarns, the woven or knitted fabrics have stretchability and conformability to the human body. Excellent tracking of human body movements, comfortable to wear, and does not restrict human body movements, so it is widely used in sports clothing, underwear, substrates and other clothing materials. In addition, due to its stretchability, it is used in medical applications such as elastic bandag...
