Embodiment Construction

[0040] The present invention will be further described with reference to the accompanying drawings.

[0041] The fabric is woven by warp and weft, warp 250DSTY; weft 26ST / R (8020) yarn + 70D spandex.

[0042] The dyeing and finishing process of the fabric is as follows;

[0043] 1. Use the fabric turning machine and unwinding machine to turn and unwind the fabric;

[0044] 2. Joint the fabric with a sewing machine;

[0045] 3. Use a pre-shrinker to pre-shrink the fabric to adjust the width of the fabric to 152cm. The pre-shrinker is equipped with three ovens through which the fabric passes sequentially. The temperature of the first steam box is 60°C, and the temperature of the second steam box is 80°C. ℃, the temperature of the third steam box is 90 ℃, and the cloth feeding speed of the pre-shrinker is 45M / min;

[0046] 4. Dye the fabric with a dyeing tank. The dyeing agent in the dyeing tank includes disperse dyes, blended dyes, PE-400 refining and dyeing one-bath leveling...

Abstract

The invention discloses a dyeing and finishing process for Chinese velvet. The dyeing and finishing process combines the steps of hot washing, acid washing, dyeing and water washing and a process flow is shortened, so that the water amount in a production process is reduced and the emission of sewage is reduced, and furthermore, energy saving and emission reduction are realized. Meanwhile, a fabric dyed and finished by the dyeing and finishing process has good dyeing yield and pure colored light.

Description

technical field [0001] The invention relates to the production of cloth, in particular to a dyeing and finishing process for Chinese velvet. Background technique [0002] Chinese velvet, also known as TT / R weft elastic brushed, is a soft and fluffy double-sided brushed fabric, which is often used in the production of coats and windbreakers. [0003] However, the traditional dyeing and finishing process of this fabric needs to be pre-treated with liquid alkali, and it needs to go through hot washing, pickling, dyeing, washing and other links, which brings a lot of energy and water resource consumption, as well as sewage discharge. How to achieve energy saving and emission reduction by shortening the technological process on the premise of ensuring product quality, that is, ensuring the color rate and stability of fabrics, has become a question for business operators. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present...
