What kind of chemical product is a scouring enzyme?

Scouring enzyme is a multi-compound enzyme that can be boiled under mild pH, temperature and simple operating conditions to completely decompose the symbiotic of natural cellulose such as cotton and linen. It can accurately open the internal channels of natural fibers without damaging the cellulose at all.

Scouring enzymes can be pre-treated with dark knitted fabrics, and a more satisfactory (slightly better than the conventional process) dyeing effect can be obtained.

Compared with the traditional alkali scouring, the scouring enzyme can comprehensively improve the treatment effect of cotton products, which is harmless to the environment, operators and equipment, and can shorten the processing time and reduce the comprehensive cost.

Compared with traditional alkali scouring, the advantages of the enzymatic cold stack pretreatment process are as follows: the process is simple. In the case of not increasing equipment investment, it can be stacked at room temperature.

Save energy. The energy consumption of water, electricity, and steam has been greatly reduced to ensure quality. Biological enzymes can accurately and efficiently remove impurities from fibers with little damage to fibers.

Environmental protection. The amount of caustic soda is greatly reduced, and the pH value of wastewater is close to neutral, which reduces the sewage treatment load and is conducive to improving the environment. The effects of enzyme dosage, treatment time and treatment temperature on the whiteness, gross efficiency, fiber length, dyeing performance and spinnability of the loose fiber were investigated by using scouring enzyme CBS, and compared with the conventional alkali scouring process.

The results showed that the optimization process of the refining enzyme CBS in the pretreatment process of cotton loose fiber was as follows: 3 g L of the refining enzyme CBS, temperature 70, treatment time 50 min, penetrant JFC G L, pH value, and liquor ratio 1 15. Compared with the traditional alkali scouring, CBS enzyme refining process conditions are mild, the damage to cotton fiber is small, the gross efficiency is high, the dyeing color is high, the feel is soft, and it has better spinnability.

Pre-treatments for cotton fabrics include desizing, scouring, bleaching, and mercerizing. The purpose of desizing is not only to remove the slurry on the grey fabric, but also to remove some natural impurities, so as to facilitate later scouring and bleaching. The desizing methods include enzyme desizing, alkali desizing, acid desizing, etc., and the most widely used is alkali desizing.

After the grey cloth is desized, most of the natural impurities (such as waxy substances, pectin substances, nitrogenous substances, etc.) are still left on the fabric, affecting the dyeing and printing process. To remove these impurities, the fabric must be boiled in a high-temperature lye. The main agent used in scouring is caustic soda, and in order to improve the scouring effect, additives should be added to the scouring liquid.

The purpose of bleaching is to remove pigments and give the fabric the necessary whiteness, while also removing residual wax, nitrogenous substances, etc. The main oxidant used for bleaching is hydrogen peroxide (hydrogen peroxide). In order to obtain a good bleaching effect and avoid fiber brittleness, an appropriate amount of oxygen bleaching stabilizer must be added.

To sum up, in the traditional pretreatment process, the following chemical products and additives sodium hydroxide, hydrogen peroxide, scouring agent, penetrant, oxygen bleaching stabilizer, etc. must be used. Due to the use of a large amount of caustic soda (i.e., sodium hydroxide) in the traditional process, it not only has a high damage to the fiber, but also needs a large amount of water to rinse the fabric after treatment, resulting in a large amount of sewage. The scouring enzyme invented by our company can replace most of the caustic soda, which can effectively solve the above problems.

Because many fibers are sensitive to alkali or do not tolerate high temperature, the pretreatment bleaching of multi-fiber fabrics is more difficult, such as the bleaching of cotton-wool blended fabrics or interwoven fabrics, and the loss of wool is relatively large; Bleaching of cotton and acrylic blends or interwoven fabrics, acrylic fiber is easy to be damaged and yellowed under strong alkali and high temperature conditions. The shortcomings of the traditional hydrogen peroxide bleaching technology are as follows: oxygen water vapor steaming (or cooking) process, which needs to be treated at high temperature (95-100 °C) for about i hours to complete the bleaching effect, which not only has high energy consumption, but also has greater damage to the fiber, the breaking strength of the fabric is significantly reduced by more than 15%, and the degradation rate of cellulose fiber is about 40-50%. In the hydrogen peroxide cold rolling stacking process, the amount of leaching is small, the stacking time is short, the change of ambient temperature and the fluctuation of washing conditions have a great influence on the bleaching effect, and the quality stability cannot be said to be satisfactory.
