Abstract

The invention discloses a dyeing apparatus and a dyeing method. A rectangular box is provided; a dye liquid is charged into the rectangular box; an inert gas is introduced into the rectangular box toform an inert environment; therefore, yarns are dyed in the dye liquid. The yarns are switched in the state of being soaked in the dye liquid and the state of being outside the dye liquid under inertgas pressurizing; so that full soaking time is extended for the yarns in the dye liquid, the dye liquid is never oxidized; dye molecules have a concentration difference when on the surface of yarn fibers and when inside the yarn fibers, so that the dye molecules can migrate from the surface of the yarn fibers to the inside of the fibers, the dye diffusion and fixing processes are more sufficient,yarn dyeing rate is increased, and dye utilization rate in the whole dyeing process is increased by about 8-18%; the quantity of dye vats is greatly decreased, so that equipment space is diminished; total volume of the dye liquid sealed by the inert gas is 2 / 5 of the total volume of a traditional dye liquid.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing device and a method thereof. 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] When traditional denim yarns are dyed with indigo dyes, sulfur dyes, reactive dyes, etc., due to the characteristics of the dyes themselves, indigo dyes, sulfur dyes, etc. can only be reduced to leuco bodies through infiltration, adsorption, and oxidation in the air.
