Abstract

The invention provides a polyester-cotton blended yarn dyeing process. According to the present invention, blended yarns are dyed through polyester dyeing, refining, cotton dyeing, soaping, color fixing, softening and drying, such that the production process is simplified, and the blended yarns can maintain the good state after the dyeing; and the refining liquid is limited so as to improve the quality of the blended yarns with the refining liquid, and the component dose, the treatment time and the treatment temperature are limited so as to improve the dyeing quality.

Description

technical field [0001] The invention relates to the field of yarn dyeing, in particular to a polyester-cotton blended yarn dyeing process. Background technique [0002] At present, when dyeing blended yarn, it is usually dyed by bleaching and dyeing, and the dyeing process is mainly two-bath method to dye the yarn, but in the dyeing process, the yarn needs to be reduced and washed to ensure the dyeing process. The polyester and cotton dyeing process can be carried out, but adding one more process will prolong the dyeing time and increase the dyeing cost, and after dyeing by the ordinary two-bath method, the yarn is prone to frizz, which affects the use of blended yarns. Therefore, it is particularly important to solve the problems that the dyeing process of blended yarns is tedious and the yarns are easily damaged. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a dyei...
