摘要
活性染料染色过程中,染色后要过酸、回潮、柔软剂;此外,分散染料染色助剂和定形对织物的色光也会产生影响。试验发现,活性染料染棉皂洗后,过酸时间要达到15 min,回潮30 min,织物色光才稳定纯正;加入柔软剂,织物色泽明显变浅。分散染料染涤纶过程中,助剂的加入和高温定形都会使织物色泽变浅。
Factors exerting influence on the shade of dyeings in dyeing process are discussed, such as acid neutralization, moisture regaining and softener agent in reactive dyeing, and auxiliaries and heat setting in disperse dyeing. It is found that the cotton reactive dyeings can obtain pure and stable shade by acid neutralization for 15 min and moisture regaining for 30 min after soaping. The shade of cotton reactive dyeings becomes obviously light after adding the softener, and the same phenomena occurs to polyester disperse dyeings after adding dyeing auxiliaries and high temperature heat setting.
