Fabric finishing is a crucial stage in textile production, aimed at enhancing the aesthetic appeal, performance, and durability of fabrics. Among the various finishing agents, enzymes, particularly cellulases, have gained significant traction due to their specificity, efficiency, and environmental benefits. At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing advanced textile auxiliary agents, including high-performance neutral cellulase enzymes (CAS 9012-54-8), to our global clientele.

Mechanism of Cellulase in Fabric Finishing

Cellulases are complex enzymes that catalyze the hydrolysis of cellulose, the main component of cotton, linen, and rayon fibers. They achieve this by breaking the β-1,4-glycosidic bonds within the cellulose polymer chains. In fabric finishing, this enzymatic action is harnessed for several purposes:

  • Bio-Polishing: Cellulases selectively remove surface microfibrils from cellulosic fabrics. This process smooths the fabric surface, reduces pilling, and improves the fabric's luster and softness.
  • Denim Washing: For denim, cellulases can create a vintage, worn-in look by abrading the fabric surface, removing indigo dye, and highlighting the warp yarns. This leads to desirable contrast effects and a softer feel.
  • Weight Reduction: In some applications, controlled enzymatic action can lead to a slight weight reduction, altering the fabric's drape and handle.

Optimizing Process Parameters for Maximum Efficacy

To achieve the best results when using cellulase for fabric finishing, precise control over process parameters is essential. Our neutral cellulase enzyme is designed to perform optimally under specific conditions:

  • pH: The recommended working pH for our enzyme is typically between 6.0 and 7.0. Maintaining this range ensures maximum enzyme activity and targeted fiber modification.
  • Temperature: The ideal working temperature is between 50°C and 55°C, though the enzyme remains active within a broader range of 35°C to 60°C.
  • Enzyme Dosage: Dosage recommendations vary based on the fabric type, desired effect, and process intensity. We advise a starting dosage range of 0.1% to 0.5% (owf) and encourage clients to conduct trials to determine the optimal level for their specific application.
