摘要
壳聚糖季铵盐(HTCC)是一种具有强阳离子性的水溶性聚合物,采用HTCC对桑蚕丝织物进行改性处理,研究改性后丝织物对活性染料的无盐染色工艺及性能.结果表明,经HTCC溶液改性后,桑蚕丝织物对活性染料的无盐染色较佳工艺为:染液pH为8.0,染色温度为90℃,染色时间为70 min.改性后的丝织物经无盐染色后,上染率、固色率及色深明显提高,水洗色牢度和摩擦色牢度也略有改善.
Chitosan quaternary ammonium salt （HTCC） is a strong cationic water-soluble polymer. Bombyx Mori silk fabric was treated by HTCC and the salt-free reactive dyeing process and property of modified silk fabric were investigated. The results showed that the optimum salt-free reactive dyeing process of silk fabric treated by HTCC was： dyeing pH was 8.0, dyeing temperature was 90 ~C and dyeing holding time was 70 min. The dyeing uptake, the fixation rate and the dyeing depth of silk fabric modified by HTCC were all increased obviously, and the washing fastness and rubbing fastness were both improved slightly.
