Abstract

The invention discloses a core permeating dyeing technology. The technology comprises the following steps that S1, yarn is subjected to yarn boiling for refining; S2, the yarn is dyed to obtain coloryarn; S3, the color yarn is washed with water; S4, the color yarn is squeezed to dry by a pair of high-pressure roller sets; S5, the color yarn is subjected to sizing to obtain sizing yarn; S6, the sizing yarn is dried. According to the technology, a color yarn drying step in a conventional technology is removed, the high-pressure roller sets are adopted for directly squeezing the yarn to 90% dry,subsequent drying is not needed, and sizing can be directly carried out. The core permeating dyeing technology has the advantages that the process of the conventional dyeing technology is improved, the drying step is removed, the energy consumption is effectively reduced, and the production resources are saved.

Description

technical field [0001] The invention relates to the technical field of textile technology, in particular to a core-through dyeing process. Background technique [0002] After more than 100 years of development, denim clothing still occupies an irreplaceable position in the field of textiles, and has been handed down to this day with its most classic styles and styles. The warp yarn of traditional denim fabric is dyed with indigo or sulfur dye, and the weft yarn is made of natural white yarn, which is woven with a 3 / 1 twill weave structure. Denim clothing made of this fabric has always been the "darling" in the hands of fashion designers and is deeply loved by people. [0003] The conventional coloring treatment steps of denim yarn include: dyeing—washing—drying—sizing—drying, and the equipment used is a combined sizing and dyeing machine. After washing and before sizing, the moisture content of the yarn needs to be reduced for better subsequent sizing. The existing sizing ...
