摘　　要：采用自制的壳聚糖衍生物CTA-CTS对棉织物进行预处理,并对制备的阳离子化棉进行活性染料无盐染色。探讨了预处理改性工艺对棉织物无盐染色性能的影响,并确定优化的预处理工艺:采用pH值为6.0的10 g/L CTA-CTS浸渍10 min,80℃烘干3 min,110℃焙烘3 min。试验证明,经CTA-CTS处理的棉织物无盐染色后,其固色率及色牢度与常规染色效果相当或更佳。Using the self- synthesized chitosan derivative CTA-CTS, cotton fabric was cationized followed by reactive dyeing without salt. Influence of pretreatment conditions on dyeing effect was investigated and the optimum conditions for pretreatment were established as follows： cotton fabric was treated with 10g/L CTA-CTS at pH value of 6.0 for 10 min, and then dried at 80℃; for 3 min, cured at 110℃ for 3min. The results indicated that the fixation and color fastness of reactive cotton dyeings pre-treated with CTA-CTS in the zero-salt dyeing process were close to or even higher than those of normal reactive cotton dyeings.
