Problems solved by technology

[0002] The textile industry is one of the traditional industries in my country and has a relatively important economic status. Cotton-polyester blended knitted fabrics have a large market demand due to their better comprehensive performance. To meet market demand, it is necessary to dye cotton-polyester blended knitted fabrics. , the traditional dyeing process adopts the two-bath dyeing process, that is, separate dyeing according to different dyes in different dyeing baths and different processes. This dyeing method has complicated procedures, low production efficiency, high energ

Embodiment 1

[0019] Example 1: A rapid cotton dyeing process for cotton-polyester blended knitted fabric after polyester dyeing, the polyester fiber of cotton-polyester blended knitted fabric directly enters the cotton dyeing process after the dyeing process, and the polyester fiber dyeing process of cotton-polyester blended knitted fabric , After the blended knitted fabric is pretreated, it is bounced by an evenly distributed fabric beating device, then wound on a set of dyeing tension rollers, dipped and moved forward in the dyeing pool.

[0020] The dyeing tension rollers are divided into upper dyeing tension rollers and lower dyeing tension rollers. Each dyeing tension roller is arranged at equal intervals, and the height of the lower dyeing tension rollers is uniform; the height of the upper dyeing tension rollers gradually increases.

[0021] The cloth flicking device is arranged at the cloth inlet end of the dyeing pool, and the cloth flicking device is arranged symmetrically on the ...

Abstract

The invention belongs to the technical field of knitted fabric dyeing and discloses a quick cotton dyeing technology for a cotton-terylene blended knitted fabric after washing and dyeing. The technology particularly comprises the following steps of adding acetic acid and dyeing assistant into a dye tank for dyeing a polyester fiber, regulating a pH (potential of hydrogen) of a system, after regulation, raising the temperature of the system to 75-80 DEG C, performing heat preservation and stirring, adding a dye into the system at a constant speed, performing heat preservation and stirring, raising the temperature to 98-102 DEG C, then raising the temperature to 130-133 DEG C, performing heat preservation and then cooling, conveying the dyed blended knitted fabric to a washing tank via a group of conveying tension rollers for alternate washing, and drying the dyed knitted fabric at last. According to the dyeing scheme, a cotton fiber dyeing process is performed immediately after polyester fiber dyeing for the cotton-terylene blended knitted fabric; the time of a fabric dyeing technology is greatly shortened; the dyeing operation efficiency is improved; the dyeing uniformity is improved; and the conveying tension rollers and a washing technology arranged at the late course of the technology improve a washing effect of the fabric after the dyeing.

Description

technical field [0001] The invention belongs to the technical field of knitted fabric dyeing, and in particular relates to a rapid cotton dyeing process for cotton-polyester blended knitted fabric after dyeing. Background technique [0002] The textile industry is one of the traditional industries in my country and has a relatively important economic status. Cotton-polyester blended knitted fabrics have a large market demand due to their better comprehensive performance. To meet market demand, it is necessary to dye cotton-polyester blended knitted fabrics. , the traditional dyeing process adopts the two-bath dyeing process, that is, separate dyeing according to different dyes in different dyeing baths and different processes. This dyeing method has complicated procedures, low production efficiency, high energy consumption, and relatively high sewage discharge. Large, does not meet the concept of energy saving and emission reduction. [0003] At present, the one-bath method i...
