Embodiment 1

[0064] The high-elastic pure spinning twill denim gray fabric is subjected to post-finishing treatment, and the gray fabric is subjected to the first pre-shrinkage treatment, low-shrinkage treatment, and second pre-shrinkage treatment.

[0065] Among them, the process of the first pre-shrinking treatment is: singeing --- desizing --- shrinking;

[0066] The process of the second pre-shrinking treatment is: washing --- opening --- drying --- shrinking;

[0067] The process of low-shrinkage treatment is: a. Put the high-elastic fabric into the overflow machine for 5 minutes, and the water temperature in the overflow machine is 130 degrees; b. Dehydrate the treated high-elastic fabric; c. The high-elastic fabric is subjected to open-width treatment; d, the high-elastic fabric is sent to a setting machine for drying treatment, the drying temperature is 100° C., and the drying time is 300 seconds.

Embodiment 2

[0071] The high-elastic pure spinning herringbone denim gray fabric is subjected to post-finishing treatment, and the gray fabric is subjected to the first pre-shrinkage treatment, low-shrinkage treatment, and second pre-shrinkage treatment.

[0072] Among them, the process of the first pre-shrinking treatment is: singeing --- desizing --- shrinking.

[0073] The second pre-shrinking process is: washing --- opening --- drying --- shrinking.

[0074] The process of low-shrinkage treatment is: a. Put the high-elastic fabric into the washing machine for loose washing treatment for 100 minutes, and the water temperature is 20 degrees; b. Dehydrate the treated high-elastic fabric; c. Perform dehydration on the high-elastic fabric. Open-width treatment; d. Send the high-elastic fabric to the setting machine for drying treatment. The drying temperature is 220° C. and the drying time is 20 seconds.

Embodiment 3

[0078] The high-elastic pure spinning plain denim gray fabric is subjected to post-finishing treatment, and the gray fabric is subjected to the first pre-shrinkage treatment, low-shrinkage treatment, and second pre-shrinkage treatment.

[0079] Among them, the process of the first pre-shrinking treatment is: singeing --- desizing --- shrinking.

[0080] The second pre-shrinking process is: washing --- opening --- drying --- shrinking.

[0081] The process of low-shrinkage treatment is: a. Put the high-elastic fabric into the washing machine for loose washing treatment for 30 minutes, and the water temperature is 40 degrees; b. Dehydrate the treated high-elastic fabric; c. Perform dehydration on the high-elastic fabric. Open-width treatment; d. Send the high-elastic fabric to the setting machine for drying treatment. The drying temperature is 150° C. and the drying time is 200 seconds.

Abstract

The invention discloses a low-shrinkage treatment method and afterfinishing method of high-elastic fabric and high-elastic fabric; the low-shrinkage treatment method of the high-elastic fabric comprises: washing the high-elastic fabric; dewatering the treated high-elastic fabric; scotching the high-elastic fabric; drying the high-elastic fabric. The low-shrinkage treatment method of the high-elastic fabric provided herein has an additional treatment step in the original fabric afterfinishing method; low-shrinkage treatment is arranged before pre-shrinkage treatment. The high-elastic fabric treated by the low-shrinkage treatment method gains high elasticity and low shrinkage, the difficulty in manufacturing high-elasticity ready-made apparel and washing the ready-made apparel is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of fabric finishing, and mainly relates to a low-shrinkage treatment method for high-elastic fabrics, a finishing method and high-elastic fabrics. Background technique [0002] At present, the method used to increase the elasticity of fabrics in the production of high-elastic fabrics at home and abroad is to design a larger reed width to increase the rebound space of spandex yarns. The problems brought about are large yarn consumption, high production costs, and more consumption. Steam, water, electricity, and labor intensity of workers, but the fabric pre-shrunk width is still difficult to shrink. Another way is to increase the number of times of pre-shrinking, using two or even three times of pre-shrinking, but at the same time, the fabric brings great pressure to continuous production. The post-finishing methods of general high-elastic fabrics include: singeing, desizing, the first pre-shrinking treatmen...
