青核桃皮色素用于柞蚕丝织物染色性能的研究

摘要

The dyeing properties of green walnut husk on tussah silk fabric were discussed.Green walnut husk coloring matter was extracted with hot water.The effects of dye concentration, pH value and temperature on dyeing were investigated.The optimum conditions of dyeing tussah silk fabric with green walnut husk were obtained by the orthogonal and single factor analysis experiments: pH value 4, volume fraction of dye liquor 16％,temperature 70 ℃.The color difference of tussah fabric could be gained through different mordant such as Cu2+,Fe2+, Al3+.The color fastness of green walnut husk dyed tussah silk fabric was good, direct dyeing and mordant dyeing sample could both reach more than level 3.The dyeing properties of after mordant dyeing were better than those of premordant dyeing.%探讨了青核桃皮色素用于柞蚕丝织物的染色性能.用热水提取青核桃皮色素,选取φ(青核桃皮色素)、PH值、温度为因素,通过正交试验及单因素分析试验优化出青核桃皮上染柞蚕丝织物的最佳工艺为:PH值4,φ(青核桃皮色素)=16%,70℃通过不同媒染剂(Cu(2+)、Fe(2+)、Al(3+)预媒和后媒处理,提高织物色差值.青核桃皮色素上染柞蚕丝织物色牢度优良,直接染色和媒染试样均达到3级以上.后媒染色效果好于预媒染色.
