Put "green underwear" on the textile industry

As one of the pillars of the traditional domestic industry, the traditional textile industry has always been a major polluter due to its high pollution, high energy consumption and large water consumption. At present, some large textile factories in China are forced to stop production under increasing environmental pressure. The traditional textile industry will be difficult to sustain without the high energy consumption and high pollution of the outerwear. How to make the textile industry a green industry with low energy consumption and low pollution is an urgent problem to be solved.

Not long ago, the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences developed a bio-enzymatic green dyeing pretreatment process, and successfully completed the application demonstration and promotion of the 100,000-meter-boiled bio-enzymatic pretreatment process in Hebei Ningfang Group. The prescription was prescribed.

The traditional pre-dyeing process consists of five steps: singeing, desizing, refining, bleaching and mercerizing. In this process, a large amount of chemicals such as caustic soda and additives must be used, which consumes a large amount of water and energy, causing serious environmental pollution. According to statistics, at present, the energy consumption per unit of fabric in China is 2.4 times that of the world average; in the case of cotton fabrics, 300 tons of water is required for the treatment of 10,000 meters of cotton fabric. At the same time, the fibers are easily damaged and the equipment is easily damaged.

In response to this situation, the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences has cooperated with Tianjin Tianfang Group and Hebei Textile Materials Supply and Marketing Co., Ltd. for three years to develop a variety of high-quality textile enzyme preparations and production processes. Their self-developed compound enzyme preparations can combine the desizing and refining in the traditional process into one step, which greatly improves the pretreatment efficiency.

According to reports, the enzymatic desizing and refining one bath is completed, which reduces the steam energy consumption, saves the cost of alkaline wastewater treatment, and reduces the amount of various chemical additives, which can significantly reduce the pretreatment cost and improve the economic benefits of the textile industry. Practice has shown that compared with the traditional alkali process, the enzymatic pretreatment process produces 12,000 meters of pure cotton cotton cloth and 11,000 meters of aramid heat wave card cloth, the cost can be reduced by 30% and 70% respectively.

It is worth mentioning that the bio-complex enzyme preparation has the characteristics of mild treatment condition, high efficiency, good specificity, etc., which not only has no damage to cotton fiber, but also improves product quality.
