Room Temperature Cellulase Used for Washing of Denim Garments

Abstract

Room-temp. Cellulase CS was used to enzymatic washing on denim garments at 20°Cand 35°C, and Novoprime 838 from Novozymes was employed at 55°C in case to evaluate their performance. Through analysis of activities of enzymes, it is indicated that CS has a relatively broad and steady action temperature range between 20～35°C. Similar mechanical and physical properties of washed garments were achieved by using CS under room temperature conditions and using Novoprime 838 at 55°C. No heating needed during enzymatic washing by using CS.
