As one of the pillars of traditional industries in China, the traditional textile industry has been a major polluter because of its high pollution, high energy consumption and large water consumption. At present, some large textile factories in China are forced to stop production under the increasing pressure of environmental protection. Without taking off the coat of high energy consumption and pollution, the traditional textile industry will be unsustainable. How to make textile industry a green industry with low energy consumption and pollution is an urgent problem to be solved.
The traditional pretreatment process includes five steps: singeing, desizing, refining, bleaching and mercerizing. In this process, a large number of chemical preparations such as caustic soda and additives must be used, which consumes a large amount of water and energy and causes serious environmental pollution. According to statistics, the energy consumption per unit fabric in our country is 2.4 times of the world average level at present; taking cotton fabric as an example, the treatment of 10,000 meters cotton fabric requires 300 tons of water. At the same time, the fibers are easy to be damaged and the equipment is easy to be damaged.
In view of this situation, pre-treated and refined enzymatic for textile
can combine desizing and refining in traditional process in one step, thus greatly improving the pretreatment efficiency.
The pre-treated and refined enzymatic for textile
is used for pretreatment, which can reduce steam consumption, alkaline wastewater treatment cost and chemical additives consumption. It can significantly reduce pretreatment cost and improve economic benefits of textile industry. Compared with the traditional alkali process, the cost of producing 12 000 m cotton cloth and 11 000 m aramid hot-wave card cloth by enzymatic pretreatment can be reduced by 30% and 70% respectively.
It is worth mentioning that pre-treated and refined enzymatic for textile also have the characteristics of mild treatment conditions, high efficiency and good specificity, which not only has little damage to cotton fibers, but also can improve product quality.
