PECH-amine在提高硫化染料摩擦牢度中的应用

Improving the rubbing fastness of the sulfur dyeings with PECH-amine

将PECH-amine(聚环氧氯丙烷胺化物)应用于棉织物硫化染料染色后的固色处理,考察了PECH-a-mine用量、NaOH用量和固色方法对棉织物耐摩擦色牢度的影响。结果表明,浸渍法较浸轧法固色效果佳。优化的浸渍法工艺条件为PECH-amine 2 g/L,NaOH 8 g/L。经浸渍法固色处理后,棉织物硫化染料染色的摩擦牢度有不同程度的提高。

Color fixing is carried out on cotton sulfur dyeings with self-made cationic polyepichlorohydrin-dimethylamine （PECH- amine）. Factors exerting influence on the finishing results are discussed, such as dosages of PECH-amine and NaOH, as well as fixing method. The results show that the fixing effect of the exhaust method is better than that of the padding method. The optimum exhaust process is PECH-amine 2 g/L and NaOH 8 g/L, and the fixed cotton sulfur dyeings feature enhanced rubbing fastness.
