Problems solved by technology

[0004] First, the three-bath dyeing process is complicated and the technical risk is very large
In the process of dyeing polyester fiber in the first bath, the staining effect of acrylic fiber and viscose fiber is different after reduction, which leads to the uncontrollable shade in the process of dyeing acrylic fiber in the second bath, and in the process of dyeing acrylic fiber, cationic dyes have a negative effect on polyester fiber. The fibers and viscose fibers are also stained, which will cause color changes, which brings a lot of trouble to technical workers, affects the stable control of the production process, and leads to unstable product quality
[0005] Second, the three-bath dyeing is divided into three steps: polyester fiber dyeing, acrylic fiber dyeing, and viscose fiber dyeing, so that the dyeing energy wastes too much and the production efficiency is low
Moreover, the three-bath dyeing also has the disadvantage of a long production cycle, which seriously restricts the improvement of production efficiency, so the three-bath dyeing method needs to be improved.

Abstract

The invention discloses a dyeing method of a terylene, acrylic fiber, viscose glue and spandex blended fabric. The method comprises the following steps: 1, blended fabric weaving: weaving a blended fabric containing terylene, acrylic fiber, viscose glue and spandex; 2, blended fabric treatment: carrying out scotching presetting on a gray cloth, and linking; 3, carrying out one-bath dyeing on terylene and acrylic fibers; 4, reducing, neutralizing, and washing with water; 5, carrying out two-bath dyeing on the viscose glue; 6, washing with water, neutralizing soaping, washing with water, and discharging the obtained cloth; and 7, post-treatment: dehydrating the blended fabric obtained in step 6, drying, and carrying out scotching setting to obtain a finished product. The method has the advantages of simple process, fastness, efficiency, energy saving, convenient operation, stability, and dyeing of high-quality and stable-product-quality terylene, acrylic fiber, viscose glue and spandex blended fabrics.

Description

technical field [0001] The invention relates to the technical field of dyeing of blended fabrics, in particular to a method for dyeing polyester, acrylic, viscose and spandex blended fabrics. Background technique [0002] The jersey fabric (34% polyester, 41.3% acrylic, 17.7% viscose, 7% spandex) made of polyester fiber, acrylic fiber, viscose fiber and spandex fiber is very popular in the international and domestic markets. High-grade knitted underwear fabrics are widely used. However, the conventional dyeing process of dark blended fabrics is very complicated. At present, three-bath dyeing (polyester fiber, acrylic fiber, and viscose fiber are dyed in three steps and three baths) is often used. The process flow is: weaving - blank opening Pre-shaping-sealing-pretreatment-washing-dyeing polyester-reduction-neutralization-washing-dyeing acrylic fiber-reduction-neutralization-washing-dyeing viscose-washing-neutralization-soaping-washing-fixing-cloth -Dehydration-drying-open...
