Biopreparation of organic cotton textiles through specific mixed enzymatic system

Abstract

Organic cotton is grown without using fertilizers in the cultivation plant as compared to conventional cotton planting Organic cotton used in textile and apparel industry for development of biodiversified products in medical textiles such as wound dressing surgical gowns and baby care skin clothing are grown in the past years The processing of organic cotton in textile wet processing is recommended by the Global Organic Textile standard which framed the guidelines for textile processing through mild chemicals and or go with enzyme technology In the present industrial practices the pectinase enzymes are used for bioscouring of cotton materials but drawback of the pectinase enzyme is it removes or break downs only pectin groups in the cotton fibre structure which is not sufficient for removal of wax oil and fatty substances in the fibre However recent biotechnology and genetic engineering advances have opened opportunities for successful applications of other enzyme systems such as lipases xylanases laccases proteases and alkaline pectinases
