Enzymatic Scouring for Better Textile Properties

Standard procedures of scouring cotton fibers and fabrics involve alkali treatment, usually with NaOH, accomplishing high effects in textile cleaning of genetic and added impurities. During harsh scouring conditions waxes, protein substances, pectine and other impurities are removed form fiber, but also leads to a some damages to the cellulose causing a high weight loss and decreasing the strength. After scouring process huge quantities of water are necessary, high energy is requied, and NaOH polluted waste waters. This traditionally procedure of scouring is ecologicaly and economicaly unfavourable, so in last few years new procedures are investigated. Enzymatic scouring with pectinases of cotton fibers and fabrics has been used since 1999. Compared with traditionaly scouring with NaOH, enzymatic scouring needs less energy, half of the amount of necessary water, and there is no pollution of waste water because enzymes are biodegredable and non toxic. This work compares textile properties of knitted fabrics after conventional and enzymatic scouring, such as degree of polymerization of cellulose (DP), wicking and knit fabric sewability.
