Biopolishing is a crucial finishing process in the textile industry, aimed at enhancing the surface quality of cellulosic fabrics. At the heart of this process are cellulase enzymes, particularly neutral cellulases, which offer a precise and eco-friendly method for achieving superior fabric aesthetics. NINGBO INNO PHARMCHEM CO.,LTD. leverages extensive research and development to provide high-quality neutral cellulase enzymes that are key to successful biopolishing operations. This article explores the scientific underpinnings of this technology and its practical implementation.

Cellulose, the structural component of cotton and other plant fibers, is a long chain polymer of glucose units linked by β-1,4-glycosidic bonds. Cellulase enzymes are a complex group of enzymes that catalyze the hydrolysis of these bonds, breaking down cellulose into smaller sugars. In textile biopolishing, specific types of cellulases, primarily endoglucanases and exoglucanases, work synergistically. They target the amorphous regions of cellulose fibers, gently abrading the fabric surface to remove protruding microfibrils or 'fuzz.' This action results in a cleaner, smoother fabric surface, reduces pilling, and enhances the fabric's sheen and softness.

The efficacy of cellulase enzymes is highly dependent on their working environment, particularly pH and temperature. Neutral cellulases, as their name suggests, operate optimally in a near-neutral pH range, typically between 5.5 and 7.5. This mild pH environment is beneficial as it minimizes damage to the fabric's strength and color retention, a common concern with acid cellulases. The optimal temperature range for most neutral cellulases falls between 45°C and 55°C. Deviating significantly from these conditions can affect enzyme activity and the final outcome of the biopolishing process.

NINGBO INNO PHARMCHEM CO.,LTD. provides precisely formulated neutral cellulase enzymes that ensure high activity and stability within these optimal parameters. Understanding the cellulase enzyme mechanism allows for effective application. For optimal results in biopolishing, factors such as enzyme concentration, liquor ratio, treatment time, and agitation speed must be carefully controlled. The recommended cellulase enzyme dosage for fabric typically ranges from 0.1% to 0.3% (o.w.f.), but this should be adjusted based on fabric type, desired effect, and specific processing equipment.

A critical step in textile finishing is the inactivation of the enzyme once the desired effect is achieved. This prevents over-processing and ensures the longevity of the fabric's finish. The standard cellulase enzyme inactivation process involves raising the temperature above 70-80°C for a short period, or adjusting the pH significantly. NINGBO INNO PHARMCHEM CO.,LTD. provides guidance on the most effective inactivation methods for their products. By mastering the science behind these enzymes, textile manufacturers can significantly elevate the quality and appeal of their cellulosic fabrics.
