柳皮果胶的提取及对真丝织物的防紫外整理性能研究
Extraction of willow bark pectin and study on anti-UV finishing with it for silk fabrics
摘要
Abstract
Pectin was extracted from willow bark with Tartaric acid as the main extractant on the premise of comprehensive utilization of willow bark. Three factors affecting pectin of extraction time, pH and solid-liquid ratio were analyzed. Pectin extraction was optimized combining orthogonal test based on univariate analysis. The extractive pectin was diluted separately into solutions of different mass concentrations to be used in silk fabrics finishing, and the anti-UV property of finished fabrics was measured thereafter. The result showed that the extraction weight of willow bark pectin was the highest and the quality was the most stable while the extracting condition was obtained in pH of 2.5 for 150 min with the solid liquid ratio of 1:40. The willow bark had a light grey color. The anti-UV property of silk fabrics was enhanced apparently and the best anti-UV property was achieved at the mass fraction 6% after finishing.关键词
