Abstract

The invention discloses a dyeing agent for a polyester fiber. The dyeing agent comprises, in weight percent, 20%-30% of disperse dyes, 13%-20% of glycerol, 3%-5% of imidazoline, 1%-3% of dispersing agents, 1%-2% of acetic acid, 2%-4% of sodium alga acid and 40%-60% of water, and the sum of the contents of the raw materials is 100%. The dyeing agent has the advantages that by the aid of an azo-typedisperse dyes, a synthetic method is simple in production process and low in cost, the dyeing agent has higher fastness to light at high temperature, color change is avoided, and a fabric prepared from polyester fibers dyed by the dyeing agent has excellent fastness to washing after heat setting or soft finishing and is easy to dye and bright and rich in color.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a dyeing agent for polyester fibers. Background technique [0002] At present, fiber types are becoming more and more abundant. Polyester fiber is the main fiber source of textiles. With the continuous improvement of people's wearing requirements and wearing performance, the high standard of color fastness made of polyester fiber has become an urgent need. [0003] Polyester fibers are generally dyed with reactive dyes, but when traditional dyeing auxiliaries and dyeing processes are used, the dyeing percentage and fixation percentage of the dye to the fiber are generally low. In order to solve this problem, a large amount of inorganic salt should be added to promote dyeing during the dyeing process, but the biggest disadvantage of adding a large amount of inorganic salt to promote dyeing is that it will make the textile feel rough and may cause scratches ...
