Bio Enzyme Technology For Cotton Textile Industry To Achieve Energy Saving And Emission Reduction

With the continuous development and progress of biotechnology,

The application in cotton textile industry is also getting more and more attention. It plays an important role in promoting energy saving and emission reduction in cotton textile industry.

As a non-toxic, environmentally friendly biocatalyst, biological enzymes can be completely biodegraded.

The development and application of bio enzyme technology conform to the requirements of green production, processing and sustainable development, and have broad prospects for development.

At present, biological enzymes are mainly used in cotton textile field such as desizing, scouring, washing, polishing, waste liquid treatment and so on.

Looking forward to decomposing PVA enzymes.

At present, the desizing process of cotton fabric mainly consists of alkali desizing and enzyme desizing.

Alkali desizing is a process at which the slurry becomes swollen to a sol state and loosely adheres to the fiber at high temperature, and the pulp is easily removed from the fabric.

Because alkali desizing can not degrade slurry, the general desizing rate is relatively low, and the UN recycled slurry needs to be scoured through the back process and washed away by a large amount of water. In addition, alkali can easily damage the fabric and pollute the environment.

It is easy to cause the high COD value of the water body and cause pollution to the water body.

In the future, with the development of enzyme development technology, if we can produce biological enzymes to decompose PVA, we will be able to solve the problem of desizing and sizing of PVA slurry.

Pectinase Scouring treatment of small pollution

At present, cotton fabric scouring is done mainly by caustic soda treatment at high temperature. By alkali scouring treatment, the wax, pectin and protein in the cuticle can be basically removed, and the uniform dyeing and finishing effect can be obtained to improve the comfortability of fabrics.

However, alkali refining is carried out at high temperature. A large amount of alkali and surfactant should be used in production. After treatment, it is necessary to neutralize acid and rinse with plenty of water.

Therefore, alkali scouring not only has great energy consumption and water consumption, but also pollute the environment easily.

The weight and strength loss of fabric during scouring is smaller than that of alkali treatment.

It has no pollution to human body and environment.

Biological water washing protection equipment

The traditional process of denim finishing is stone washing. It relies on the mechanical friction and flow scouring of pumice and clothing, causing the fabric to wear on the surface of the garment, and the indigo dye on the fibers to fall off partially, so that the fabric can produce natural imitation effect and at the same time the fabric becomes soft and comfortable.

Pumice washing and finishing has great damage to fabrics, and causes breakage and even hole breaking.

Biological washing has the following advantages: good processing quality, high production efficiency, no pollution to the environment, no need to add softeners in general, and less equipment wear.

Bipolishing improves product performance

Most fabrics containing natural cotton fibers have tiny, loose or protruding fiber ends, which make the fabric look like a fluffy appearance.

Biological polishing is a kind of finishing method which uses biological enzyme to remove the fuzz on the surface of fabric, and achieves the smooth surface effect, and makes the fabric achieve soft, fluffy and other unique properties.

The degradation of cellulosic fibers by cellulase can effectively remove the hairiness on the fabric surface, make the fabric surface bright and clean, gloss bright, clear texture, improve product quality, at the same time, it can also improve the handle, improve the pilling performance and improve the wearability of the fabric.

In short, the use of enzyme technology in textile technology can greatly promote the conservation of multiple resources.

Enzyme technology is in line with the requirements of energy conservation and emission reduction and sustainable development in the textile industry.

At present, it is limited by the cost and scope of application.

Therefore, to speed up the research and development of bio enzyme technology, expand the application field of enzyme and reduce the cost of use is one of the directions for joint efforts of biotechnology and textile industry.
