Problems solved by technology

[0006] Second, it is easy to cause color difference between the edge and the middle, and the shade near the edge of the cloth is relatively yellow. When the warp beam is dyed, the equipment is fully pumped, because the edge of the cloth is more likely to be in contact with the dyeing solution, and glacial acetic acid is added at low temperature. The cause of competition dyeing, which eventually leads to the generation of chromatic aberration in the edge
[0007] Third, it is not conducive to energy saving, emission reduction, consumption reduction, and low production efficiency
The color flower and color difference in the edge caused by dyeing must be repaired, which will consume a lot of water, electricity, steam and coal, and seriously affect the normal production

Abstract

The invention provides a dyeing and finishing process for green chinlon / spandex side stretch fabric. The dyeing and finishing process comprises a dyeing process. A dyeing agent prepared from 1-1.5 g / L of acid leveling agent, 0.8-1 g / L of acid-releasing agent, 1 g / L of chelating dispersant, 0.5-2% (o.w.f.) of acid light yellow and 0.3-4% (o.w.f.) of acid emerald blue is adopted for the dyeing process. The bath ratio is 1:10, dyeing synchronism of acid light yellow and acid emerald blue is greatly improved, competition of two dyes for fiber dyeing is effectively retarded, and the dyeing defect phenomena generated during dyeing are reduced. Meanwhile, side-to-centre shading generated during warp beam dyeing is avoided, and reworking for dyeing defects is reduced.

Description

technical field [0001] The invention belongs to the field of fabric dyeing and finishing, in particular to a dyeing and finishing process of green brocade / spandex four-way stretch knitted fabric. Background technique [0002] Nylon / spandex four-way stretch fabric is an elastic fabric interwoven with nylon fiber and spandex fiber. It has a unique fiber yarn structure, fashionable fabric texture and excellent wearing performance, and has a very broad market prospect. Green is a common color in nature, representing freshness, hope, safety, calm, comfort, life, peace, serenity, nature, environmental protection, growth, vitality, youth and life, so green nylon / spandex four-way stretch fabric is very popular among people favorite. [0003] The dyeing and finishing process of the traditional green brocade / spandex four-way stretch fabric includes refining process, pre-shrinking, presetting, warp dyeing, color fixing, washing and setting, wherein acid dyes and glacial acetic acid ar...
