摘要
为减少活性染料染色中盐的使用,对棉织物的电化学无盐染色方法进行探索。讨论棉织物电化学染色中的外加电压、起染温度、通电时间对活性染料浸染结果的影响;分析采用电化学无盐染色后织物的色深值与各影响因素之间的关系。试验结果表明:活性染料通过浸染法染棉织物时,将电化学无盐染色同常规加盐染色的方法对比,前者能明显提高染料的上染量,不仅染后织物的K/S值提高,而且减少了残液中染料及常规染色中加入的大量NaCl等对环境的污染。
An electrochemical dyeing method without salt used on cotton fabrics has been studied for the purpose of reducing the amount of salt in reactive-dyeing process. Some factors, such as applied voltage, beginning temperature of dyeing and electrified time, have been discussed. Relationship between K/S value obtained from the electrochemical dyeing of fabric without salt and these factors was analyzed especially. Compared with the general salty dyeing method, the electrochemical dyeing method without salt could raise the uptake of dyes remarkably. In addition, this method not only increased K/S value but also decreased the environment pollution which might be caused by general salty residual dye liquids.
