Problems solved by technology

In short, the above two schemes are to increase the elasticity of cotton cloth through strong twisted plied yarn and special finishing process, while reducing the fabric softness and weaving processability.
Moreover, the elastic elongation of cotton cloth is often less than 15%.

Embodiment 1

[0033] Yarn preparation: Warp is common 12 S Cotton combed yarn; weft yarn is cotton core elastic yarn 11 S (twenty one S ), of which core yarn count 21 S , the twist factor is 650, and the twist factor is 300.

[0034] Weaving: On the rapier loom, use core elastic weft yarn and ordinary cotton sizing to weave gray fabric with warp yarn in 3 / 1 right twill weave structure, increase warp yarn tension and weft insertion tension appropriately during weaving, and the reed on the machine is No. 51 reed , the weft density of the upper machine is 41 threads / inch, and the warp density of the upper machine is 50 threads / inch.

[0035] Gray fabric post-processing process: singeing, desizing, loose mercerizing, resin finishing, high temperature setting, pre-shrinking.

[0036] Singeing process: cloth feeding, brushing, singeing, fire extinguishing, cloth falling, the speed of the singeing machine is 90 m / min, the singeing method is two positive and one reverse, the distance between th...

Embodiment 2

[0043] Yarn preparation: warp yarn is cotton core elastic yarn 12 S (twenty one S ); weft yarn is cotton core elastic yarn 11 S (twenty one S ), of which core yarn count 21 S , The twist coefficient is 650, and the twist coefficient is 350.

[0044] The core elastic warp is prepared on the sizing-dyeing combined machine, and the sizing-dyeing speed is 20 m / min. Among them, indigo is used for dyeing; sizing is mainly coated with starch sizing, and the temperature of the sizing pot is 98 ° C to increase the penetration of sizing in the yarn, and the sizing rate is 6%.

[0045] Weaving: On the rapier loom, core elastic weft yarns and sizing-dyed core elastic warp yarns are used to weave gray fabrics with a 3 / 1 right twill weave structure, and the warp yarn tension and weft insertion tension are appropriately increased during weaving. The reed on the machine is No. 55 reed. The weft density of the upper machine is 40 threads / inch, and the warp density of the upper machine is ...

Abstract

The invention relates to a production method of an all-cotton-core elastic fabric. The production method comprises the steps that 1, fine strong twisted yarns are used as core yarns, all-cotton roughyarn fiber is re-twisted fiber, and a sirofil spinning technology is applied to prepare all-cotton-core elastic yarns; 2, beaming and size-dyeing are conducted on the all-cotton-core elastic yarns, the treated all-cotton-core elastic yarns are used as warp yarns and / or weft yarns, and a gray fabric is obtained through twill weave structure knitting on a machine; 3, singeing, desizing and slack mercerization are conducted on the gray fabric, and finally resin finishing and setting are performed to obtain the all-cotton-core elastic fabric. By applying the all-cotton-core elastic yarns and adopting a low-tightness knitting technology and a series of after treatment processes, an original all-cotton fabric with poorer elasticity and stability produces a larger elastic elongation, meanwhile elastic residual recovery is reduced, its size stability is improved, the current requirements for elastic elongation and elastic recovery of all-cotton fabrics are met, and the quality defect is brokenthrough that all-cotton elastic fabrics have rough and hard hand feel.

Description

technical field [0001] The invention belongs to the field of all-cotton fabrics, in particular to a production method of all-cotton core elastic fabrics. Background technique [0002] Cotton fabric has the characteristics of soft touch, moisture absorption and breathability, comfortable wearing, natural and environmental protection, etc., and has been favored by consumers. But all-cotton fabric also causes wrinkle easily in wearing and washing because of its poor elasticity, affects attractive in appearance, has limited its use to a certain extent. Especially when used as a denim fabric, cotton denim is often thick and stiff, and the user's comfort experience is poor. In order to improve the elasticity of denim cotton fabrics, the method of adding spandex yarn or nylon or high elastic yarn to prepare blended yarn is generally adopted. Although the addition of elastic fibers improves the elasticity of fabrics to varying degrees, these chemical fibers inevitably have the pro...
