Cotton fibre rapid staining process

Abstract

The invention relates to the dyeing and finishing project technical field in the printing and dyeing industry production and discloses a cotton loose fiber rapid dyeing technique, comprising the dyeing of the cotton loose fiber, the post treatment and the drying, wherein, in the dyeing technique, the apposition scouring and the dyeing technique are adopted. The prior cotton loose fiber dyeing adopts the high temperature boiling-off or the low temperature pre-treatment, angle water should be discharged after the processes, otherwise, the dye uptake is low and the dye use level is increased. The apposition scouring rapid dyeing technique can short the production flow time by 20 percent, decrease the energy such as water, electricity and air consumption by more than 20 percent; moreover, the ability of fiber is increased due to the shortened fiber processing time, the tactility and the spinnability are improved, the production cost is lower and the environment is protected.

Description

technical field

[0001] The invention relates to the technical field of dyeing and finishing engineering in the printing and dyeing industry, in particular to the dyeing and post-treatment process of cotton loose fibers. Background technique

[0002] With the progress of society and the improvement of living standards, people pay more and more attention to the environment, and the country's environmental protection policies are becoming more and more strict. Vigorous rectification is being carried out. Energy conservation and emission reduction have become the most important goals at present. At the same time, the protection of water resources Insufficient, requires us to reduce the water consumption of printing and dyeing, and reduce the water consumption per unit of dyeing.

[0003] Traditional cotton loose fiber dyeing adopts high-temperature scouring treatment. Generally, soda ash or scouring agent is added to boil the cotton. The temperature is high and the energy consum...
