Continuous dyeing and finishing process for bamboo-cotton-polyester blended antibacterial anti-ultraviolet anti-static woven fabric

Abstract

The invention discloses a continuous dyeing and finishing process for bamboo-cotton-polyester blended antibacterial anti-ultraviolet anti-static woven fabric. The woven fabric is sequentially subjected to the steps of strengthened singeing, high-temperature enzyme desizing, scouring, bleaching, mercerizing, sizing, dyeing and finishing. In the step of dyeing, polyester fiber components are dyed by disperse dye, the disperse dye is padded, then two groups are pre-dried by infrared rays, then hot air drying is carried out by adopting a three-section pre-drying room, the temperature of a first box is 50-60 DEG C, the temperature of a second box is 70-90 DEG C, the temperature of a third box is more than 100 DEG C, and finally the polyester fiber components are baked at 210 DEG C for 3.5 minutes; according to the color fastness requirement, the reactive dye or the vat dye is determined to be used for dyeing the bamboo / cotton fibers. The scouring and bleaching auxiliary agent with the environment-friendly low-alkaline property is adopted, the environment-friendly enzyme desizing process is combined, dyeing and finishing are conducted, and meanwhile the cloth cover quality and the whiteness effect of the bamboo-cotton-polyester blended fabric are guaranteed, and the excellent anti-ultraviolet, antibacterial, deodorant, moisture-absorbing and quick-drying performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a continuous dyeing and finishing process for bamboo-cotton-polyester blended antibacterial, anti-ultraviolet and anti-static woven fabrics. Background technique [0002] The main customers of bamboo cotton polyester fabric are large oilfield units at home and abroad, mainly engaged in outdoor operations, and the working environment is relatively harsh. The perennial hot, humid, sweaty, and bacterial breeding environment is not good for the health of operators. However, the current tooling Most of them are made of polyester / cotton blended fabrics, CVC fabrics, etc. The fabrics feel hard, easy to pilling, poor moisture absorption and perspiration effects, etc. Obviously, they cannot meet the needs of customers. Oilfield units urgently need a UV-resistant and antibacterial fabric. The anti-odor, moisture-absorbing and quick-drying fabrics are used to improve...

AI Technical Summary

Problems solved by technology

[0005] 1. A bamboo-cotton blended fabric and its production process, which are made of 65-80% Egyptian long-staple cotton and 20-35% bamboo fiber blended. The bamboo fiber is the warp yarn, and the Egyptian long-staple cotton is the weft yarn. The warp yarn density is 60-65 threads / cm, the weft density is 70-100 threads / cm, and the yarn of long-staple cotton is 180N / 3. The production process includes the following steps: warping, sizing, shaping, weaving, desizing, washing, and scouring , stenter setting, did not add polyester fiber, and did not study the dyeing process, there is no suitable dyeing process, the strength of the fabric is relatively poor, the processing technology is simple, and it is not suitable for tooling fabrics

[0006] 2. A dyeing and finishing process for bamboo / cotton blended knitted fabrics, comprising the following process steps: gray fabric manufacturing—grain fabric inspection—cutting and shaping—fabric trimming and width facing inward—boiling and bleaching—polishing—dyeing—drying—padding Finishing with moisture-absorbing and quick-drying additives—finished product; the dyes are Argosol Red BF-3B, Argosol Yellow BF-3R, and Argosol Navy BF-RRN. The overflow dip-dyeing process is used, and the production efficiency is low. The color difference between them is large, which is not suitable for mass production. The dyes used are ordinary reactive dyes, and the light fastness and perspiration fastness are very poor. They are not suitable for outdoor clothing, and a large amount of chemicals are added in the finishing process to improve The fabric has moisture absorption and quick-drying performance, which is very environmentally friendly

[0009] Because it is a tooling fabric for oilfield units, the requirements for various strength indicators are very high, and the proportion of polyester in the fabric cannot be low, which leads to the need to dye the three fibers in the same process, which greatly increases the difficulty of dyeing and finishing. As a three-component fabric not only It is related to the weaving process of blended fabrics, and is also closely related to the subsequent dyeing and finishing process. No matter how good the fabric is, if the dyeing and finishing fails, it will not be possible to obtain a fabric that feels comfortable, durable, and has a beautiful color
