摘　　要：真丝绸通过阳离子改性剂改性后,在蚕丝纤维上引入阳离子性基团,可大大提高活性染料对真丝织物的上染率和固色率。研究确定了真丝绸改性的最佳工艺为:改性剂用量10 g/L,改性时间30 min,改性温度60℃,改性pH9.0;真丝绸用活性染料雅格素黄N-SR无盐染色的最佳工艺:染色pH7.5,沸染50 min。改性染色后丝绸的各项牢度较好,染色深度明显增加。Silk fabrics were modified with cationic modifier,some cationic groups were introduced to the surface or inter of silk fabrics.The dyeing and fixing rate of silk fabrics with reactive dyeing were improved.It was shown that the optimum process of silk modifying： the concentration of modifier 10？g/L,time 30min,temperature 60？℃ and modified pH 9.0.The best dyeing process of salt-free dyeing for silk with reactive dyes Argazol yellow N-SR： boiling temperature,dyeing holding time 50min,dyeing pH 7.5.After modified,silk fabrics achieved good dyeing fastness,the depth of dyeing was also increased.
