摘　　要：采用重氮盐对蚕丝蛋白质所含的酪氨酸残基进行侧基偶合化学修饰,并对修饰后的蚕丝进行各项性能测试。结果显示:对蚕丝织物先浸轧10g/L的NaOH溶液,再采用1g/L重氮盐进行偶合,经过蛋白质侧基偶合化学修饰的蚕丝织物上形成偶氮类色素,经该化学修饰的有色蚕丝织物,具有较好的耐光稳定性能。This paper uses diazonium salt to conduct side coupling chemical modification on tyrosine residues contained in silk protein and conducts various performance tests on modified silk. The result shows that azo pigment forms on silk fabrics subject to protein side coupling chemical modification, which are first immersed in 10 g/L NaOH solution and then coupled by using 1 g/L diazonium salt. Colored silk fabrics with such chemical modification have a better light resistance stability property.
