Applications Of Pre-Treated And Refined Enzymatic For Textile

Traditional scouring mostly relies on high concentration of NaOH to remove impurities in cellulose fibers at high temperature. The extensive use of NaOH has led to the textile printing and dyeing industry as a major component of environmental pollution. With the continuous improvement of people's understanding of the environment, the printing and dyeing industry urgently needs to replace the traditional process of high temperature and high alkali. With the development of alkaline pectinase pretreatment research, biological pretreatment has become an inevitable trend of future pretreatment methods, and is accepted by more and more printing and dyeing engineers and technicians.

The pre-treated and refined enzymatic for textile are mainly alkaline pectinase, combined with amylase, cellulase, xylanase, lipase and other multiple complex enzymes. The wax (hydrophobic complex), pectin and protein in the fibrinolytic layer are partially removed by the  pre-treated and refined enzymatic for textile, and the secondary layer is modified to remove impurities and proteins on the fibre surface. The color substance can be dyed evenly to improve hydrophilicity, softness and wearability of fabrics. It first forms a complex with pectin on the fibers, and then hydrolyzes it. The original pectin is split and separated from the fibers.

The pre-treated and refined enzymatic for textiles are used in various pretreatment processes of cotton, linen and their interwoven or blended fibers/yarns and fabrics. Compared with traditional alkali scouring, it can comprehensively improve the treatment effect of cotton products and the wearability of the final products. It is harmless to the environment, operators and equipment, shorten the processing time and reduce the comprehensive cost. The pretreatment of cotton fabrics is completed under mild pH, temperature and simple operation conditions, and the coexistence of natural cellulose such as cotton and hemp is thoroughly decomposed. It can accurately open the inner passage of natural fibers, improve the dyeing performance of cellulose fibers without damaging the fibers, and effectively improve the weight loss (excessive loss) of fibers, dyeing color, cylinder difference, streaks, wrinkles and other problems in the conventional process. Make the fabric get fluffy and soft handle and balanced and consistent wettability, improve the product quality in an all-round way. Especially for new high-grade fiber fabrics, such as bamboo fiber, organic cotton fiber, soybean protein fiber, corn fiber, color cotton fiber and other fabrics pretreatment has incomparable advantages.
