Problems solved by technology

Chemical fiber materials have excellent characteristics and are widely used, especially blended materials, which are widely used in the textile industry because of the functionality of various fibers. However, due to the special structure of chemical fiber materials, the dyeing requirements are very strict. And the consumption of dyestuffs is high, causing serious environmental pollution
Conventional chemical fiber blended yarns need to be dyed, and some blended yarns require two-bath dyeing, resulting in waste of energy and dyes. At present, there is no particularly effective method for controlling wastewater discharge in the textile industry

Embodiment

[0018] The specific production steps of 60S / 2 cotton polyester (65 / 35) plain woven fabric are:

[0019] ①. Use the red G (solvent red 212) masterbatch of Jiangyin Jinqiao Trading, mix it with white slices at a ratio of 3:7, and then melt and extrude at high temperature to produce red fibers;

[0020] 2. Draw the above-mentioned colored staple fiber with natural color cotton fiber in an amount of 35% by mass to obtain a red cotton polyester roving with 65% cotton and 35% polyester, then spun, twist the obtained spun yarn, and spin into 60S / 2 cotton polyester blended yarn;

[0021] ③, mercerizing: the above-mentioned yarns are subjected to mercerizing treatment in a yarn mercerizing machine, the concentration of alkali in the treatment solution is: 30 degrees Baume; the temperature of the treatment solution: 20°C; the applied tension: stretching 4%; the treatment time is 6.5min; the zero-emission mercerized yarn production process is used in the mercerizing process. The applic...

Abstract

The invention discloses a production method for a zero-discharge yarn-dyed and woven fabric and belongs to the field of textiles. The production method comprises the following steps of: preparing chemical fiber synthetic fibers or regenerated cellulose fibers by applying a color master-batch coloring mode; preparing blended colored yarns by blending the prepared chemical fiber synthetic fibers or regenerated cellulose fibers with cotton fibers according to the required color; finishing the blended yarns by adopting a zero-discharge mercerized finish method; and weaving on a weaving machine by adopting a non-slurry woven fabric weaving method and then finishing to obtain the zero-discharge yarn-dyed and woven fabric. Due to the use of the method, the production method of the complete zero-discharge environment-friendly yarn-dyed fabric can be obtained. Wastewater discharge can be completely avoided and the pollution to water is avoided.

Description

technical field [0001] The invention relates to a production method of a zero-emission yarn-dyed woven fabric, which belongs to the field of textiles. Background technique [0002] The textile industry has always been considered as an unenvironmentally friendly industry due to the discharge of waste water due to its dyeing and other treatments, especially the chemical fiber blended materials that are widely used at present. Chemical fiber materials have excellent characteristics and are widely used, especially blended materials, which are widely used in the textile industry because of the functionality of various fibers. However, due to the special structure of chemical fiber materials, the dyeing requirements are very strict. And dye consumption is high, serious to environmental pollution. Conventional chemical fiber blended yarns need to be dyed, and some blended yarns require two-bath dyeing, resulting in waste of energy and dyes. At present, there is no particularly ef...
