Environment-friendly pigment dyeing process

Abstract

The invention relates to an environment-friendly pigment dyeing process which specifically comprises the following steps: (1) performing the following process flow, namely performing pretreatment scouring and bleaching, removing hair and enzymes, performing cationic agent treatment, washing with water, performing pigment dyeing, washing with the water, fixing, dewatering, drying and setting; (2) performing knitted fabric pretreatment; (3) performing cationic modification treatment, namely dyeing at room temperature by using a cationic modification agent, regulating the pH value, controlling the heating speed to be 1-2 DEG C per minute, controlling the test bath ratio to be 1 to (25-30), heating to the temperature of 60-70 DEG C, preserving the temperature for 20-30 minutes, washing with the water at the normal temperature, and performing the pigment dyeing; and (4) performing the pigment dyeing, wherein in the dyeing test stage, the initial dyeing temperature is generally controlled to be 30-40 DEG C, the heating speed is controlled to be 1-2 DEG C per minute, the test dyeing temperature is 60-70 DEG C, and the heat preservation time is 20-30 minutes. The process disclosed by the invention is environmentally friendly, good in effect and obvious in benefit, and pigments can be well dyed.

Description

technical field [0001] The invention relates to an environmentally friendly paint dyeing process, which belongs to the technical field of paint dyeing. Background technique [0002] Paint dyeing has simple process, bright color, short process, and not too high requirements for equipment; paint color paste has complete color spectrum, good sublimation fastness and light fastness, and it has a set of characteristics that reactive dyes cannot match. Brilliant fluorescent color spectrum; paint dyeing has strong adaptability to fibers, good reproducibility, stable hue, suitable for dyeing cotton fibers and their blended or interwoven fabrics, and can obtain unique, novel and fashionable fabric effects. [0003] Another major feature of paint dyeing is that it is very in line with the current concept of ecological dyeing and finishing, energy saving and emission reduction, and has the characteristics of energy saving and little environmental pollution. It is also an innovative tec...

Problems solved by technology

[0004] In recent years, with the market's demand for the style of paint dyeing products, the dyeing and finishing industry and its related garment industries have paid more attention to the development of paint dyeing varieties. The development of the textile and garment market has played a certain role; however, for knitted fabrics, there is a big difference compared with the conventional paint pad dyeing process, and there are some production practices in batch production on overflow dyeing equipment. Problems and difficulties; due to the special structure of knitted fabrics, after dyeing with paint, it is easy to appear color patterns, creases and friction marks on the surface of the cloth surface; there are still shortcomings such as poor rubbing fastness (dry, wet rubbing and scrubbing rubbing) place
