Description

Technical Field

[0001] The utility model belongs to the technical field of printing and dyeing equipment, and specifically relates to a one-bath two-step dyeing equipment for polyester-cotton fabrics. Background Art

[0002] The traditional dyeing process of polyester-cotton knitted fabrics is generally cotton fiber scouring and bleaching, disperse / reactive two-bath dyeing, that is, scouring and bleaching first, then dyeing and washing, and then over-dyeing cotton. The advantages of this process are that the scouring and bleaching are clean, both dyes can be dyed under the best conditions, and the highest fixation rate and fastness level can be obtained. There is ample room for the selection of disperse dyes and reactive dyes, and the final dyeing effect can be adjusted by reactive dyes.

[0003] However, the disadvantage of the two-bath process is that the entire wet processing process is time-consuming. After one dyeing, the cloth needs to be dehydrated, and the pH value needs to be adjusted after the dye is cooled. This takes more than 10 hours, and the production efficiency is low.
