一种多胺类无醛固色剂的应用性能研究

摘要

Self-made novel polyamine fixing agent was used in fixation treatment on nylon fabric dyed by the acid dyes. And the best optimized fixing process was provided. The nylon fabric dyed by acid dyes was treated via two dipping and padding under the conditions of fixing agent 90 g/L, the fixing temperature at 60℃, dipping for 30 min, pH 6 and liquor retention of 80%. And then the fabric was pre-dried at 80℃for 3 min and baked at 130℃for 3 min. The property tests show that washing fastness and wet rubbing fastness can reach 4 and 3 scale for nylon fabrics dyed with acid dyes, respectively. From the point of wet rubbing fastness, the self-made fixing agent can present the good effect for acid dyes.%将自制的新型多胺类无醛固色剂对酸性染料染色锦纶织物进行固色处理，并优化出最佳的固色工艺：酸性染料染色锦纶织物→两浸两轧(固色剂90 g/L，固色温度60℃，浸30 min，pH为6，轧余率80%)→预烘(80℃，3 min)→焙烘(130℃，3 min)。性能测试发现：酸性染料染色的锦纶织物，其耐洗色牢度达到4级左右；湿摩擦牢度达到3级。就湿摩擦牢度来看，自制固色剂在酸性染料上的固色效果较好。
