摘要
对蚕丝织物进行高温、日晒、蛋白酶处理 ,测定织物处理前后丝素对活性染料上染率、固着率和总固着效率的影响。试验结果表明 ,蚕丝经处理后对活性染料的染色性能有所下降。通过红外光谱分析和氨基酸组分分析发现 ,处理后蚕丝表面的酪氨酸含量降低。
The silk fabric was treated with high temperature, insolation and protease, the dyeability, fixation rate and total fixation efficiency of reactive dyes were measured before and after treatment. It showed that the dyeing behaviors of reactive dyes were descended after treated with the mentioned three methods. According to the FTIR (ATR) and amino acid analysis, the tyrosine content in silk fibroin was decreased after treatment. The relationship between amino acid content and dyeing behaviors of reactive dyes was discussed.
