摘要
采用自制壳聚糖预处理真丝绸,然后分别用艾蒿、苏木、黄连提取液对整理前后的真丝绸进行染色,研究了壳聚糖整理前后蚕丝绸的染色性能。结果表明,经壳聚糖整理后,真丝绸经艾蒿、苏木染料染色样品的色深值(K/S值)明显提高,经黄连染色样品的色深值略有降低,三种天然染料的染色牢度基本保持不变,壳聚糖预处理对染色织物色相影响不大。
Silk fabric was first pretreated with chitosan,then dyed with natural dyestuff extracted from mugwort, sappanwood and coptis chinensis respectively. The dyeing properties of silk fabrics with and without chitosan pretreatment were evaluated. The K/S value of fabrics dyed with mugwort and sappanwood dyes were increased remarkaldy after being pretreated with chitosan,while the K/S value were decreased slightly for the fabric dyed with coptis chinensis. The colour fastness of fabrics dyed with these three kinds of natural dyes remain unchanged on the whole. And chitosan pretreatment produced a little effect on coloure tones of dyed fabrics.
