摘要
Abstract
Hemp fibers pretreated with acid pectinase and xylanase were degummed once again with the traditional sodium hydroxide. The influences of the amount of enzyme, treating time and temperature, pH and the dosage of sodium hydroxide in the second degumming on scouring effect were analyzed, and the opti-mum technological conditions were determined as the amount of pectinase was 9%(omf), xylanase dosage was 12%(omf), the time was 120 min, the temperature was 50 ℃, pH was 4.6 and the concentration of sodi-um hydroxide in second degumming was 6 g/L. Compared with bleached hemp fibers with traditional scouring method, the whiteness of the bleached hemp fibers with combined method remain nearly unchanged, the weight loss rate, breaking strength and the residual gum rate was better.关键词
