摘要
选用自制的阳离子改性剂WLS对棉织物进行浸轧改性,研究浸轧改性工艺条件对棉织物硫化染料浸轧染色性能的影响,优化了工艺:二浸二轧(WLS 15 g/L,氢氧化钠4 g/L,轧液率75%)→烘干(50℃,2.5 min).评价了改性棉织物硫化染料浸轧染色的性能,结果表明:改性棉织物具有比未改性棉织物更高的K/S值,在达到相同染色深度的情况下,改性棉织物的染料用量可以大幅减少,能节约染料,减少污水,降低成本.
Cotton fabric was modified by padding technology method with self-made cationic agent WLS. The effects of modified conditions on the pad dyeing property of cotton fabrics with sulfur dyes were studied. The optimum technology was obtained： two dipping and padding, WLS 15 g/L, sodium hydroxide 4 g/L, pick up 75%, drying at 50 ℃ for 2.5 min. The dyeing property of sulfur dyed cotton fabric was evaluated. The results showed that K/S value of the modified cotton fabric was greatly improved. The dyes dosage of modi- fied cotton fabrics could be significantly reduced under the circumstances of the same color depth with the un- treated cotton fabrics. Therefore dyes could be saved and the sewage treatment and production costs could be reduced.
