摘　　要：通过实验探讨了茜草染料不同提取方法对染料产量和染色工艺的影响。在不同发酵时间、发酵溶剂和提取溶剂的情况下提取植物染料,并以提取液的吸光度、所染布样的K/S和R值为依据找到了最佳提取工艺。探讨了不同媒染剂对染色性能的影响。测试了染色织物的皂洗牢度。Based on experiment this paper mainly discussed the influences of different extraction methods of the madder on the dye production and dyeing process.Firstly,we selected the different fermentation times,fermentation solvents and extraction solvents to extract plant dyestuff and chose the best method of extraction according to the absorbance value,K/Svalue and Rvalue of dyed fabrics.This paper investigated the influence of the dyeing performance with different mordants.At last the soaping fastness of the fabric were also studied.
