摘要
采用天然决明子色素对山羊白湿革染色。从决明子及芦荟中提取天然色素及媒染剂,对山羊皮革进行染色后,再采用铝盐固定。实验测定了不同pH下的颜色值(K/S),确定了pH 4.0较为合理有效。进一步对染色坯革进行色牢度测试,证明了芦荟汁的媒染有良好的颜色稳定性,天然色素对无铬鞣革的绿色制造有着积极意义。
Natural cassia seed pigment was used to dye goat wet white leather.Natural pigment and mordant were extracted from cassia seed and aloe vera,and then used to dye goat leather,followed with the fixation by aluminum salt.The color values(K/S)at different pH environments were measured,and the pH of 4.0 was determined to be reasonable and effective.The color fastness test results of the dyed crust leather proved that the medium dyeing of aloe vera juice could result in good color stability.These results showed that the natural pigment had positive significance for the green production of chromium-free leather.
