Problems solved by technology

However, due to the great difference in the physical properties of pure cotton and bamboo fiber, there are certain problems in the dyeing of fabrics blended with pure cotton and bamboo fiber, such as many process steps, long process, and color fastness after the two are dyed together. Inconsistencies in the degree of bamboo fiber will lead to premature fading of the bamboo fiber part, resulting in the premature loss of use value of the product

Abstract

The invention discloses a dyeing process of a bamboo-cotton fiber blended fabric. The process comprises the six steps of enzyme desizing and scouring, singeing, oxygen bleaching, dehairing enzyme finishing, dyeing and postprocessing. The dyeing process has short flow and few working procedures. Through precisely selecting a working solution desizing, scouring and padding prescription and a working solution oxygen bleaching and padding prescription, precisely controlling the process conditions of desizing and scouring as well as oxygen bleaching and reasonably selecting a dyeing and color fixing postprocessing process, the color fastness of the bamboo-cotton fiber blended fabric is improved, the consistency of the fastnesses of bamboo fiber and cotton fiber is kept, and the service life of the blended fabric is prolonged.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a dyeing process of bamboo-cotton fiber blended fabrics. Background technique [0002] With the improvement of living standards, people have higher and higher functional requirements for textiles, and a single fabric can no longer meet people's needs. The development of blended multifunctional fabrics has become a current hot spot. [0003] Pure cotton fabrics are loved by people because of their good air permeability, strong moisture absorption, comfortable wearing, soft hand feeling, biodegradation, and not easy to pilling. However, pure cotton fabrics are poor in gloss and poor in elasticity. Stretch is uncomfortable, has influenced the aesthetic feeling and wearability of pure cotton fabric. [0004] Bamboo fiber is the fifth largest natural textile element after the four natural fibers of cotton, linen, wool and silk, and is a real "ecological fiber". Bamboo fib...
