摘要

Tea pigments as biological materials were extracted in this paper.Applications of turmeric and tannic acid during the silk dyeing with tea extract were studied.By changing mordant dyeing methods,concentration of mordant,dye solution pH value and dyeing concentration,we tried to study the effect of natural mordant.The results showed that two kinds of mordant were more suitable for pre-mordant.When the tannic acid was 5 g/L,the turmeric was 0.025 g/L,and the dye solution pH value was 5,the dyeing effect was optimal.Furthermore,when the dyeing concentration was diluted 5 times,the dyed fabric color was fuller.With the optimum mordant dyeing process conditions,the colors fastness to washing were acceptable.
