The Neutral Desizing Enzyme For Textile Treatment Technology At Medium Temperature Should Know By Te

Since the beginning of the 20th century, the number and types of neutral desizing enzyme for textile used in textile industry have increased significantly. As the textile wet processing sector continues to seek sustainable solutions to replace the use of chemicals, the use of enzymes has penetrated into many sectors of textile wet processing. Manufacturers constantly evaluate and improve their enzymes to shorten the wet processing time and save energy, especially textile pretreatment.

In addition, the use of enzymes in washing formulations to accelerate the removal of stains provides a more sustainable cleaning process for clothing. At the same time, the removal of color from dyeing and finishing wastewater is also the focus of research and development.

In textile wet treatment, compared with traditional chemical treatment, neutral desizing enzyme for textile can provide the following potential advantages:
1. Enzymes can save water, energy and chemicals.
2. Enzyme treatment can reduce environmental pollution.
3. Enzyme treatment can improve productivity.
4. Enzyme treatment was mild.
5. The function of enzymes is specific.
6. Enzymes can improve the quality of textiles.
7. There are few harmful components in the composition of enzymes.
8. Enzymes have the characteristics of high efficiency and biodegradability.

The inactivation of neutral desizing enzyme for textile follows first-order kinetics with or without additives. Addition of calcium acetate, calcium chloride, calcium lactate, histidine and water-soluble chitosan could increase the thermal stability of alpha-amylase. Among them, water-soluble chitosan has the most effective effect on the stability of alpha-amylase, which can maintain the stability of the enzyme above 80 C. Under the same conditions, adding water-soluble chitosan can make the desizing rate more than 95%, and the mass fraction of alpha-amylase can be reduced from 1.5% to 0.5%. These beneficial results indicate that there will be a more sustainable desizing process in the future.
