Problems solved by technology

[0003] The price of traditional pure cotton yarn has risen sharply, and most consumers now recognize chemical fiber products. The blended knitting products of acrylic fiber, wool and cupro fiber have increased significantly and are very popular among consumers. However, the acrylic fiber, wool and cupro fiber Three kinds of raw materials with different properties are dyed by one-bath method, which tends to lose sight of the other, resulting in low utilization rate of dyes, poor dyeing quality, and great difficulty in processing technology

Abstract

The invention provides a method of dyeing an acrylic fiber / hair / copper ammonia fiber blended knitting fabric by use of a one-bath two-stage process. The dyeing method is characterized by technically comprising the following steps: (1) pre-treating; (2) dyeing acrylic fiber / hair / copper ammonia fiber; (3) neutralizing; (4) soaping; (5) performing color fixation. Various dyes and assistants are placed in a same dye bath, and the temperature and pH value of the dye bath are changed in different dyeing periods of time, so that cationic dyes, weak acid dyes and active dyes meet the optimal dyeing condition to dye various fibers in different properties at the same time, thereby simplifying the production step, improving the production efficiency, improving the utilization ratio and the dyeing quality of the dyes, and meanwhile, further saving a lot of water resources, reducing the discharge of sewage so as to facilitate environmental conservation.

Description

technical field [0001] The invention relates to a textile dyeing method, in particular to a one-bath two-stage dyeing method for acrylic fiber / wool / cupro ammonia fiber blended knitted fabrics. Background technique [0002] With the increasing awareness of environmental protection and energy saving in human society, people pay more and more attention to the development and research of environmental protection, energy saving, and high-efficiency products. For the printing and dyeing industry with serious energy consumption and pollution, it has become the development direction of dyeing and finishing processing to develop energy-saving, high-efficiency, and environmentally friendly textiles through process improvement. The traditional two-bath dyeing method not only causes a waste of water resources, but also has many procedures, a long process, time-consuming and labor-intensive problems, and secondary dyeing sometimes causes uneven coloring, which is easy to cause defective ...
