How To Make The Textile Industry A Low Energy Consumption And Low Pollution Green Industry?

As one of the pillars of traditional industry in China, tradition

The industry has always been a big polluter due to its large pollution, high energy consumption and large water consumption.

At present, some large textile factories in China are forced to stop production under the pressure of environmental protection.

The traditional textile industry will not be able to get rid of the clothes with high energy consumption and high pollution.

How to make the textile industry become a low energy consumption and low pollution green industry is an urgent problem.

Not long ago, the Tianjin Institute of industrial biotechnology of the Chinese Academy of Sciences developed the green dyeing pretreatment process with biological enzyme method, and successfully applied the demonstration and extension of the 100 thousand meter cloth biological enzyme pretreatment process in Hebei Ningbo Group.

The traditional dyeing pretreatment process includes 5 steps: singeing, desizing, refining, bleaching and mercerizing.

In this process, a large amount of caustic soda and auxiliaries and other chemical agents are required to consume a lot of water and energy, resulting in serious environmental pollution.

According to statistics, the energy consumption per unit of fabric in China is 2.4 times that of the world average.

For example, 10 thousand meters of cotton fabric processing requires 300 tons of water.

At the same time, fiber is easy to damage and equipment is easy to damage.

In view of this situation, the Tianjin Institute of industrial biotechnology of the Chinese Academy of Sciences has launched cooperation with Tianjin Tian Fang Group and Hebei textile joint material supply and Marketing Co., Ltd., and after three years, a variety of excellent textile enzyme preparations and production processes have been developed.

The complex enzyme preparation developed by them can combine the desizing and refining in the traditional process into one step, thus greatly improving the pre-treatment efficiency.

According to the introduction, enzymatic desizing and refining in one bath can reduce steam energy consumption, save the cost of alkaline waste water treatment and reduce the dosage of various chemical auxiliaries, which can significantly reduce the cost of pre-treatment and improve the economic benefits of the textile industry.

Practice has proved that compared with the traditional alkaline process, the cost of producing 12000 meter cotton cotton cloth and 11000 meter aramid heat wave card can be reduced by 30% and 70% respectively by the enzyme pretreatment process.

It is worth mentioning that biological complex enzyme preparation has the characteristics of mild treatment, high efficiency and specificity. It not only has little damage to cotton fiber, but also improves.

Quality.
