Example Embodiment

[0110] Example 1

[0111] (1) (i) A 20-count 100% cotton spun yarn (manufactured by Tsuzuki Textile Co., Ltd., "TS20 single yarn") with a twist number of 600 times / meter (Z twist) was prepared as a spun yarn. The number of twists of the spun yarn per 2.54cm is T=15.24 times, the count S=20, by the formula: K = ( T / S ) The calculated twist coefficient K is

[0112] 15.24 / 20 = 15.24 / 4.47 = 3.24 .

[0113] (ii) A polyvinyl alcohol multifilament (56 dtex) (yarn dissolved in water at 80°C) (manufactured by Kuraray Co., Ltd., "Water-soluble Vinylon") was prepared as a water-soluble yarn.

[0114] (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"...

Example Embodiment

[0118] Example 2

[0119] (1) Using 40 cotton double-strand yarns as warp yarns, using the composite twisted yarn obtained in Example 1(2) as weft yarns, woven into a plain weave fabric (plain weave) with 25 warps / cm and 20 wefts / cm The blending rate of composite twisted yarns in the grey fabric 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. It can be woven or knitted plain fabric at high speed and has excellent mass productivity (weaving speed 0.1m / min).

[0120] (2) The plain weave grey fabric obtained in (1) above is soaked in hot water at 80°C for 30 minutes (bath ratio = 1:10) to dissolve and remove the water-soluble yarns in the composite twisted yarn forming the weft of the grey fabric, Next, the grey cloth was taken out of the water and dried at 150°C for 2 minutes. The elongation in the warp and weft directions of the grey fabric thus obtained was measu...

[0121] Example 3

[0122] (1)(i) Prepare 40 100% cotton spun yarn (manufactured by Tsuzuki Textile Co., Ltd., "TS40 single yarn") with 800 twists / meter (Z twist), and supply two of the spun yarn Two-for-one twister (manufactured by Murata Machinery Co., Ltd., "36M"), twists 600 times per meter (S twist) to produce double-stranded yarn.

[0123] (ii) A polyvinyl alcohol multifilament (56 dtex) (a yarn dissolved in 80°C water (manufactured by Kuraray Co., Ltd.), "Water-soluble Vinylon") was prepared as a water-soluble yarn.

[0124] (2) Supply the two-ply yarn (spun yarn) and water-soluble yarn prepared in (1) above to a two-for-one twister (manufactured by Murata Machinery Co., Ltd., "36M"), and the number of twists (two twists) is 1000 times / M (Z twists) to produce a composite twisted yarn [the ratio of the number of twists B of the composite twisted yarn to the number of twists A of the spun yarn (B / A) = about 1.67].

[0125] (3) Cut a predetermined length (1m) of yarn from the ...

Abstract

The present invention relates to the production of woven or knitted fabrics or fabrics, which have high yarn strength, can be woven or knitted with high-speed looms or knitting machines, will not cause problems such as thread breakage, and have high stretchability sex. The present invention also prepares a composite twisted yarn, which at least twists a spun yarn and a water-soluble yarn, the twist direction of the composite twisted yarn is opposite to that of the spun yarn, and satisfies the following necessary conditions (1 ) or (2): (1) The twist number of the composite twisted yarn is 1.3-3 times that of the spun yarn, and the ratio (weight ratio) of the spun yarn to the water-soluble yarn is spun yarn/ Water-soluble yarn = 20/80-98/2; (2) further twist the elastic yarn (2) stretched to 2-5 times, and the twist number of the composite twisted yarn relative to the twist number of the spun yarn is 0.3-3 times, while the ratio (weight ratio) of spun yarn (1) to the above-mentioned elastic yarn (2) is spun yarn (1)/elastic yarn (2)=50/50-99.9/0.1, spun yarn (1) and the total amount of elastic yarn (2) and the ratio (weight ratio) of water-soluble yarn (3) is: total amount of spun yarn (1) and elastic yarn (2)/water-soluble yarn (3)= 30/70-99/1.

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. Manufacturing 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 ban...
