Bio-polishing is an important means of improving the surface quality of cotton fabrics. Fabrics woven from natural fibers such as cotton and hemp, when treated with cellulase, can effectively remove surface pilling and achieve a clean, smooth fabric surface. Cellulase is also the most widely applied enzyme category in the textile industry, classified into three major types according to pH characteristics: acid, neutral, and alkaline cellulases. Acid cellulase was the earliest to be applied. However, as the textile industry has continuously raised its requirements for processing mildness, process compatibility, and fabric protection, neutral and alkaline cellulases emerged and have gradually expanded the application boundaries of cellulase.

Alkaline cellulase exhibits the highest activity in an alkaline environment of pH 9.0–10.5. Its mechanism of action involves hydrolyzing the fine pillings on the cotton fiber surface, causing entrapped particulate soils to lose their anchoring points and fall off. Since household laundry detergents are predominantly alkaline, alkaline cellulase can be well formulated with them, making it an ideal choice for modern laundry powders and liquids. However, its application in textile processing remains extremely limited.

In the textile industry, the cellulases used for Bio-polishing are mainly acid and neutral cellulases. Conventional Bio-polishing processes have mostly employed acid cellulase. However, under acidic conditions, the glycosidic bonds in cotton fibers are sensitive to acid, and the acid and enzyme produce a synergistic hydrolysis effect, leading to fiber damage to the fabric itself and an increase in weight loss, thereby affecting the finished product quality. To address this issue, Baico Biotech is textile enzyme and household detergent enzyme manufacturer in China .BBT has developed a series of neutral cellulases and Bio-scouring enzymes containing neutral cellulase components, providing milder and more efficient solutions for fabric pre-treatment. For example, the Bio-scouring enzyme RF838-W(D) can complete desizing, scouring, and polishing in a single bath at 55°C for 60 minutes. It operates under mild conditions, specifically and efficiently decomposing surface pillings on fibers, causing minimal damage to the fabric body, and effectively improving absorbency. Baico biotech is textile bio-scouring enzyme producer. The granular neutral cellulase NEF®2100 can be used synergistically with catalase. After a 10-minute de-bleaching step, dyeing can proceed immediately without the need for draining, achieving simultaneous dyeing and polishing. This not simplifies the process flow but conserves energy consumption and reduces wastewater treatment costs for mills.

BBT is not merely an enterprise focused on enzyme research and production; it is a participant in the textile industry's green transformation and process upgrading. Looking ahead, BBT will continue to leverage enzymes as a bridge, providing the textile industry with more systematic, professional, and sustainable integrated solutions, helping the textile industry achieve a win-win outcome in both quality and environmental responsibility.
