Problems solved by technology

[0003] In conventional dyeing, more than 2-10 kg of wastewater will be produced for every 1 kg of fiber fabric dyed, which seriously pollutes the environment.
[0004] In addition, in the bath dyeing process, due to the production and physical and chemical treatment of the fiber, it is difficult to ensure the uniform distribution of the internal structure crystal region and the amorphous region, and the fabric is prone to dyeing defects such as color difference, color spots, and color flowers. The dyeing of ordinary dyeing methods is even The color fastness is poor in grades 3.5 to 4

Embodiment Construction

[0022] The invention relates to a method for weaving dye-free mixed fiber and color-mixed fabrics. The fabric is made of single-sided plain weave, two 32S siro-spun yarns are used to ply and form yarns, and the yarn twist is 300 twists / meter. ; Described siro spinning yarn, blending ratio is 25% cotton fiber, 35% polyester fiber, 40% bamboo pulp fiber. Weft plain knitted fabrics are knitted on a computerized flat knitting machine. Fabric structure: plain weave on one side; horizontal density: 75 longitudinal rows / 10cm; vertical density: 56 horizontal rows / 10cm; needle size: 12G; gram weight: 280 grams / square meter.

[0023] Among them, polyester staple fiber (recycled polyester) is used for dope dyeing.

[0024] Product process

[0025] Siro spinning → rewinding → weaving piece → sleeve → flat car → hand sewing → washing → drying → ironing → packaging → storage.

[0026] The drawing process of siro spinning is the key process of mixing raw materials. In order to ensure unif...

Abstract

The invention relates to a method for weaving a dye-free combined-filament mixed-color fabric. The method is characterized in that an adopted fabric weave is formed through single-side plain weave, a yarn is formed by stranding two 32S siro spinning yarns at the yarn twist being 300 twists / meter, and the siro spinning yarns is prepared from 25% of cotton fibers, 35% of polyester fibers and 40% of bamboo pulp fibers in blending ratio. The prepared fabric is free from dying, is low-carbon and environment-friendly and has good wearability.

Description

technical field [0001] The invention relates to a weaving method for dye-free mixed fiber mixed color fabric. Background technique [0002] The traditional textile technology is "spinning first and then dyeing". Fibers are first spun and weaved, and then dyed into various required colors by yarn-dyed mills or printing and dyeing factories, and finally processed into textile fabrics and clothing. Dyeing is the most polluting industry in the textile industry chain. Printing and dyeing wastewater accounts for 80% of the total production wastewater in the entire textile industry. Printing and dyeing wastewater has a large amount of water, complex components, deep color, high alkalinity, and high organic content. The general dyeing process is gray sweater fabric→pretreatment→high temperature and high pressure dyeing→setting. [0003] In conventional dyeing, more than 2-10 kg of waste water will be produced for every 1 kg of fiber fabric dyed, which seriously pollutes the environ...
