A NEW ENZYMATIC PROCESS FOR THE PREPARATION OF ABSORBENT COTTON FROM NON SPINNABLE SHORT STAPLE COTTON

摘要

Invention relates to an enzymatic process for preparation of absorbent cotton from short staple cotton. The process steps involve of short staple cotton is incubated with 0.5% pectinase preparation of pH 8.0 at 55°C for 30 min in a substrate to liquor ratio of 1:20. The said incubated cotton is squeezed and treated with hot water (85°C - 90°C) for 30 min. The said incubated cotton again squeezed and treated with hot water (85°C - 90°C) for 30 min and followed by washing in cold water. The said washed cotton is bleached with hydrogen peroxide (about 30% WN H202) at 85°C - 90°C for 1 h keeping the substrate to liquor ratio at 1:20 followed by washing and drying. The said washed cotton air dried and opened on Shirely machine and various properties determined.
