摘要
以水为溶剂提取大黄素,并用该提取液对真丝绸染色,通过正交实验和极差分析确定了大黄素提取和上染真丝的最佳工艺条件.大黄素提取:将大黄在80℃水煮90 min,液料比为1∶20,提取2次;媒染工艺条件:80℃,FeSO4 6%(owf),浴比1∶40,45 min;染色工艺条件:60℃,浴比1∶40,染料质量浓度X g/L,pH=8,60 min.在此条件下,真丝可以获得较好的染色效果(耐摩擦牢度普遍提高).
Rhubarb was extracted with water, and silk fabrics were dyed with the extracts. The optimal conditions for rhubarb extraction and dyeing were obtained by orthogonal experiments and differential polarography analyses. The extraction was done by boiling at 80 ℃ for 90 min,and liquor ratio of 1：20, and extracting twice. Mordanting was carried out at 80 ℃ for 45 min with FeSO4 6% （owf） and liquor ratio 1：40. Dyeing was performed at 60 ℃ for 40 min at pH 8 with dye concentration of X g/L. Good dyeing results of silk fabrics were obtained under these conditions.
