Abstract

The invention relates to the technical field of dyeing technique in the textile industry and particularly relates to a cotton fabric dyeing technique. The cotton fabric dyeing technique comprises the steps of bio-enzyme boiling-off pretreatment, primary washing, dyeing treatment, soaping, secondary washing, drying and final softening treatment, finished product packaging and the like, wherein firstly, the bio-enzyme boiling-off pretreatment effectively ensures the later dyeing, the dyeing uniformity and stability of the finished product can be improved, and the damage to the cotton fabric can be reduced; secondarily, by adopting a reactive dye in the dyeing processing, the dye-uptake rate and color fixing rate of the cotton fabric can be effectively improved, and good level-dyeing effect can be achieved. In addition, the cotton fabric dyeing technique has the characteristics of being simple in technique, convenient to operate, good in dyeing effect, low in energy consumption, capable of reducing the environment pollution, and the like.

Description

technical field [0001] The invention relates to the field of dyeing technology in the textile industry, in particular to the cotton fabric dyeing technology. Background technique [0002] Cotton fabric series products are becoming more and more popular in the international and domestic markets. Cotton fiber is a hydrophilic fiber, which has the advantages of air permeability and moisture permeability. At present, domestic manufacturers use traditional sulfur dyes to dye cotton fabrics. This cotton fabric dyeing technology has problems such as complicated process, high energy consumption, and poor quality of cotton dyed fabrics. Contents of the invention [0003] The object of the present invention is to provide a cotton fabric dyeing process with simple process, convenient operation, good dyeing effect, low energy consumption and environmental protection. [0004] In order to solve the existing problems of the background technology, the present invention adopts the follo...
