Abstract

The invention discloses a dyeing process of Lycra cotton-containing knitted fabrics and mainly aims at solving the problems of large amount of water and coal consumption, and long time and high power consumption of a traditional process. The dyeing process comprises a presetting step, a hemming step, a pretreatment step, a dyeing step, an after-treatment step and an after-finishing step, which are orderly implemented; the presetting step comprises the procedure of adding auxiliaries to a rolling liquid system of a setter; the pretreatment step comprises the procedures of heating a bathtub and then preserving heat, and then washing by use of overflowing water. The dyeing process is characterized in that the tea saponin is used for bleaching instead of the hydrogen peroxide; as the tea saponin does not damage equipment, the tea saponin can be added in the presetting step for bleaching, and the operation of removing the hydrogen peroxide in the pretreatment step is avoided, so that the flow is shortened and the process is simplified, and the heat preserving temperature in the pretreatment step is also reduced. More importantly, the water consumption, coal demand and power consumption of the dyeing process are all reduced and the purpose of saving energy sources is realized, and the time taken by the process is reduced.

Description

technical field [0001] The invention relates to a dyeing process of knitted fabric containing Lycra cotton. Background technique [0002] Cotton knitted fabrics are more and more popular because of their good air permeability, good hygroscopicity, soft texture and comfortable wearing, especially the colorful cotton knitted fabrics containing Lycra. Knitted fabrics containing Lycra cotton have been widely used in sportswear series, underwear series, etc., and are indispensable in our life. [0003] The dyeing process of the traditional Lycra-containing cotton knitted fabric includes presetting process, seaming process, pre-treatment process, dyeing process, post-treatment process and post-finishing process. [0004] The traditional dyeing process of knitted fabrics containing Lycra cotton includes: [0005] (1) pre-setting process [0006] At present, many dyeing and weaving enterprises use open-width setting machines to carry out the pre-setting process when manufacturing...
