Application of Immobilized Cellulases on Ramie Fabric Finishing

Abstract:

Cellulase was immobilized on carrier ZH-EP and ZH-HA using glutaraldehyde as cross linking agent. The optimal reaction temperature of immobilized enzyme was determined to be 30°C. The immobilized enzyme was stable and showed no activity decrease after 60 days storage at room temperature. The immobilized enzyme and free cellulase was treated on ramie fabrics and the relative mechanical properties were tested. The results indicated that cellulase treatment could not only decrease the surface roughness of fabric but also affected its breaking strength and tensile length,while immobilized cellulase with less damage to the ramie fabric strength.
