Abstract

The invention discloses a terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing process, which belongs to the technical field of pretreatment, dyeing and afterfinish processes of knitgoods. The process comprises the following steps: performing oxygen bleaching refining on cotton and refining oil removal on terylene/cotton/chinlon/spandex according to the prior oxygen bleaching refining and oil removing technological requirements; respectively adding various dyes and auxiliary agents to perform one-bath dyeing on the terylene/the cotton/the chinlon/the spandex; and finally performing softening treatment according to the prior softening treatment technological requirements, wherein the dyes and the auxiliary agents consist of a dispersing dye, a high-temperature neutral fixing reactive dye, a weak acidic or neutral dye, a chelating dispersant, sodium sulfate, a disperse leveling agent, a pH regulator P-7 and the like. The process reasonably selects the low-temperature dispersing dye and the high-temperature neutral fixing reactive dye, adopts one-bath process for dyeing, shortens the process flow and the dyeing time, reduces the using amount of steam and water, reduces pollution discharge, improves the production efficiency, and reduces the dyeing cost.

Description

technical field [0001] The invention relates to a polyester / cotton / nylon / spandex multi-component seamless underwear dyeing process, which belongs to the technical field of pre-treatment, dyeing and post-finishing processes of knitwear. Background technique [0002] The existing dyeing process of polyester / cotton / nylon / spandex multi-component seamless underwear is mainly three-bath dyeing, that is, dyeing polyester, dyeing cotton, and dyeing nylon in three baths. The dyeing process is: oxygen bleaching, refining and removing of cotton Oil→hot water washing→water washing→dyed polyester→hot water washing→reduction cleaning→hot water washing→water washing→dyeing cotton→hot water washing→soap washing→water washing→dying nylon / spandex→hot water washing→water washing→softening treatment, etc. The existing process mainly has problems such as long process and dyeing time, easy damage to products, unstable color, water consumption, energy consumption, and large sewage discharge.
