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 present invention relates to a kind of dyeing method of wool / cupro ammonia fiber blended fabric, selects Lannasol dye produced by American Huntsman Textile Dyeing Chemical (China) Co., Ltd. to carry out one-bath dyeing; Add Abai Run C as the dyeing method during the dyeing process Anti-wrinkle lubricant, adding penetration enhancer Abuchlor FFC-01, the method includes dyeing and aftertreatment: 1. Dyeing: the wool / cupro ammonia fiber blended fabric is loaded into the overflow dyeing machine, adding glacial acetic acid, Abusil FFC-01, Abai Run C, Yuan Mingfen and Lannasol dyes, keep warm at 90°C±2°C for 20-30 minutes, then cool down to 70°C±2°C, add soda ash, keep warm for 50-70 minutes, liquor ratio: 1:15-20; 2. Post-treatment process: first place the dyed wool / cupro fiber blended fabric in soap solution 209, add soda ash, treat at 80-90°C for 20-30 minutes, rinse and then place on ice In acetic acid, treat at 40°C±2°C for 10 minutes, bath ratio: 1:15-1:20. The invention has good dyeing effect and good color fastness. Moreover, there is little damage to the fabric during 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...
