Copper ammonia fiber colored woven fabric and manufacturing process thereof

Abstract

The invention relates to a cuprammonium rayon yarn-dyed fabric and the corresponding manufacturing process. The fabric is woven by interlacing a pure cotton yarn and a cuprammonium rayon yarn; wherein, the warp of the fabric is 32 to 40 pure cotton dyed yarn, and the weft of the fabric is 32 to 40 cuprammonium rayon dyed yarn; the fabric texture is 11 / 13 compound twill or plain weave poplin. The manufacturing process mainly comprises yarn preparation, weaving, finishing and finished product examination, and the key of the process lies in the pre-treatment, dyeing, and post-treatment of the weft and the finishing of the fabric. The invention has the advantages that: for the fabric, the property of strength and good wear resistance of the cuprammonium rayon is rational utilized; the hygroscopicity, the air permeability, the antistatic property, the soft, smooth and qualitative texture, the wearing comport and the excellent wearability of the fabric are ensured; for the manufacturing process, shortcomings such as uneven dyeing, big color difference between inner and outer layers of the package, big color difference between batches and low one time dyeing rate in the package dyeing caused by high dyeing uptake rate, high dyeing uptake amount and high fixation amount of the cuprammonium rayon are overcome.

Description

technical field [0001] The invention relates to a fabric in the textile field and a manufacturing method thereof, in particular to an interwoven fabric containing cupro ammonia fiber colored yarn and a manufacturing process thereof. Background technique [0002] Cupro fiber is a new type of regenerated cellulose fiber. Its advantages are: good strength and wear resistance, excellent hygroscopicity, air permeability and antistatic properties, and its fabric is soft, smooth, silky and comfortable to wear , Wearing performance is excellent, with all the advantages of silk, suitable for making high-grade clothing fabrics. However, the dyeing of cupro fibers has always been a difficult problem, because the dyeing rate of dyes on cupro fibers is significantly higher than that of cotton, polyester and cotton fibers, and the amount of dyeing and fixation is also much higher than that of cotton, cotton, and cotton. Polyester cotton and other fibers; the dyeing depth of cupro fiber i...

AI Technical Summary

Problems solved by technology

However, the dyeing of cupro fibers has always been a difficult problem, because the dyeing rate of dyes on cupro fibers is significantly higher than that of cotton, polyester and cotton fibers, and the amount of dyeing and fixation is also much higher than that of cotton, cotton, and cotton. Polyester cotton and other fibers; the dyeing depth of cupro fiber is about 50% higher than that of cotton fiber, which makes cupro fiber prone to uneven dyeing when the cheese is dyed, the color difference between the inner and outer layers of the cheese is large, and the difference between production batches and cylinders is large , a low infection rate and other issues

In addition, copper ammonia fiber is relatively expensive, and the cost is relatively high

Because of these deficiencies, the promotion and utilization of cupro ammonia fiber are limited

At present, copper ammonia fiber is generally used in blending with wool, cotton fiber or synthetic fiber to make up for its dyeing deficiency or reduce product costs. Products that use colored yarn interwoven with other fibers are rare, and there are no relevant technical materials. arrive
