摘要
采用季铵型阳离子改性剂3-氯-2-羟丙基三甲基氯化铵(CHPTAC)对棉织物进行阳离子改性处理,然后在无盐条件下进行活性染料深色染色。研究了改性前后棉织物表面微观形态和热稳定性的变化,评价了改性棉织物无盐深色染色的染色性能。研究结果表明:CHPTAC改性对棉织物表面微观形貌影响较小,棉纤维表面无损伤,改性后的棉纤维晶型不变,结晶度降低,热稳定性略有降低。C.I活性黑5在改性棉织物无盐染色时的提升力较未改性棉织物有盐染色要好,改性棉织物活性染料无盐深色染色的匀染性好,色光变化小,耐摩擦色牢度和耐皂洗色牢度较未改性棉织物有盐染色要高。
Cotton fabric is cationized by CHPTAC and dyed with reactive dyes to gain ultra-deep shades without salt. SEM, XRD and TG are used to characterize the change in surface morphology and thermal stability of cotton fabric. The dyeing properties of modified cotton fabric are investigated. The results indicate that cationizatien has little effect on the surface morphology and the thermal stability of the cot- ton fabric. Compared with the unmodified cotton fabric dyed with salt, C.I Reactive Black 5 has a better build-up property on cationized cotton fabric dyed without salt, When the dye concentration is same, the cationized cotton fabric has higher K/S value than the unmodified one. The cationized cotton fabric shows good levelness, while the cationization itself has little influence on shade. The color fastness to soaping and rubbing of the dyeings is also better than the unmodified one.
