Problems solved by technology

[0006] Conventional reactive dyes are highly reactive dyes with poor penetration during dyeing. In the dyeing of blended fabrics, poor penetration reduces the uniformity of dyeing
Most reactive dyes have a tendency to hydrolyze, especially when dyeing at high temperature, but in comparison, high reactive dyes are easier to hydrolyze than medium and low reactive dyes. The hydrolysis of reactive groups will reduce the color fixing ability of dyes, thus affecting The size and sample difference after fabric dyeing, as well as the stability of fabric dyeing and the reproducibility of dyeing

Abstract

The invention relates to a method for dyeing wool / copper ammonia fiber blended fabrics. A bath process for dyeing is realized by adopting Lanasol dyes produced by US Huntsman Textile Effects (China) Co. Ltd. In the dyeing process, Abairun C is added as an anti-wrinkle lubricant and Abaixiao FFC-01 is added as a penetration enhancer. The method comprises the steps of dyeing and post treatment: (1) dyeing: putting the wool / copper ammonia fiber blended fabrics into an overflow dyeing machine, adding glacial acetic acid, the Abaixiao FFC-01, the Abairun C, glauber salt and the Lanasol dyes, keeping the temperature of 90+ / -2 DEG C for 20-30 minutes, cooling to 70+ / -2 DEG C, adding calcined soda and keeping the temperature for 50-70 minutes; and (2) post treatment: putting the dyed wool / copper ammonia fiber blended fabrics in soaping agent 209, adding calcined soda, treating at 80-90 DEG C for 20-30 minutes, putting in glacial acetic acid after rinsing and treating at 40+ / -2 DEG C for 10 minutes. The bath ratio in the dyeing process is 1:15-20, and the bath ratio in the post treatment process is 1:15-1:20. The invention has the advantages of good dyeing effect, good color fastness and little damage to the fabrics in the dyeing process.

Description

(1) Technical field [0001] The invention relates to the selection of dyes for dyeing wool / cupro ammonia fiber blended fabrics, the selection of auxiliary agents corresponding to dyeing in the dyeing process, and the matching dyeing and post-treatment processes. It belongs to the technical field of fiber dyeing. (2) Background technology [0002] Wool / cupro blended fabric is a blended fabric produced with high-count untwisted cupro filament as warp and worsted wool single yarn as weft. The fabric has the characteristics of smooth hand feeling, charming luster, elegant color, good drapability and unique style. [0003] Cupro ammonia fiber is a kind of regenerated cellulose fiber. It is made of spinning solution by dissolving loose cotton linters and other natural cellulose raw materials in concentrated ammonia solution of copper hydroxide or alkaline copper salt. After soaking, it is coagulated and shaped in a spinning bath of water or dilute alkali solution, and then decomp...
