Low temperature finishing method of textiles

Abstract

The invention provides a low-temperature after finishing method of textiles. The method comprises the following steps: (1) washing and milling treatment in an industrial washing machine: adding 0.5-4.0% of washing and milling agent, firstly soaking the textiles for 0-30 minutes, then stirring the textiles for 2-40 minutes, then carrying out deep dehydration and rinsing for 1-10 minutes and then carrying out deep dehydration, wherein the weight ratio of water to the textiles is (1:1)-(1:25) according to the types of the textiles and the water temperature is 0-20 DEG C (normal temperature); (2) softening treatment in the industrial washing machine: adding 3.0-5.0% of softening agent and 2.0-8.0% of smoothening agent, firstly soaking the textiles for 0-30 minutes, then stirring the textiles for 0-40 minutes and carrying out moderate dehydration, wherein the weight ratio of water to the textiles is (1:15)-(1:25) and the water temperature is 0-20 DEG C (normal temperature); (3) drying the textiles at 70-90 DEG C in a special oven for spinning; and (4) ironing (decatizing) and setting the textiles. The method has the following beneficial effects: energy consumption and carbon dioxide emission can be reduced, the fibers can be protected, weight loss of the textiles can be reduced and the production efficiency can be improved; the method is simple and practical; and the textiles have good softness, bulkiness and smooth and glutinous feel and are seldom subjected to pilling. The method plays an active role in promoting increase of economic benefits in the cashmere processing industry and green development of the spinning industry.

Description

technical field [0001] The invention relates to the field of textile finishing, in particular to a method for low-temperature finishing of all textiles. Background technique [0002] The energy-saving mark of the textile industry is the cleaning of raw materials (such as velvet, wool, etc.), the second is dyeing, and the third is finishing (dyeing and finishing); reducing energy consumption in the textile processing process can not only improve the protection of fibers, improve Comprehensive economic benefits are also the most important link in realizing green textile production. According to the strategic guideline of our company's "Work Plan on the Development of Green Textile Auxiliaries and Green Textile Technology", on the basis of realizing low-temperature velvet (wool) washing in 2010, a breakthrough was made in the "Applied Technology of Textile Low-temperature Finishing" at the beginning of this year Low-temperature finishing is to reduce the temperature of 40°C-45...

AI Technical Summary

Problems solved by technology

[0004] At present, the technical status of textile finishing at home and abroad is as follows: 1. From the perspective of additives, washing shrinkage agents are anionic products (greater destructive power to fibers, not easy to biodegrade), high foam, and difficult to rinse (need to rinse. 2-3 times), the water consumption is large, the labor intensity of production workers is high, the softening agent has poor penetration ability to fibers at room temperature, and the softening effect is also poor; 2. From the perspective of technology, because traditional finishing is It is carried out at a temperature of 40°C-50°C, so it increases the consumption of energy and damages the strength of the fiber, which is not conducive to the protection of the ecological environment, and the weight loss of the fabric before and after finishing is obvious, which increases the finishing process. Difficulty and cost, comprehensive effect of textile finishing (softness, smoothness, bulkiness) deviation
