用红木叶生态染料染棉的工艺探讨

Investigation of the dyeing process of cotton with eco-dyes from mabogany leaves

用生态染料红木叶对棉进行染色,采用不同的媒染剂(明矾、氯化亚锡、氯化钙和硫酸亚铁)及用量,结合预媒、同媒和后媒3种媒染方法进行试验,对试样在水洗、摩擦、日晒以及汗渍牢度等方面的性能差异进行了对比.

Eco-dyes from mabogany leaves were used to dye cotton. Different mordants such as alum stannous chloride, calcium chloride and ferrous sulfate were used, and 3 methods （pre-mordanting, simultaneous mordanting and post-mordanting） were assayed. The properties of the samples were tested for water washing rubbing, sunlight and perspiration fastnesses.
