中性和弱酸性染料染色氨纶的性能和工艺

The Dyeing Behaviors and Technology of Neutral and Weak Acid Dyes for Polyurethane Fiber

探讨了中性和弱酸性染料分子结构与氨纶染色性能的关系 ,提出适宜于染氨纶的染料的IOB值 (无机性 /有机性比值 )范围 ,并对影响染色的工艺因素进行了系统试验和分析。

It is investigated the relationship between the structures of neutral and weak acid dyes and the dyeing behavior of polyurethane fibers, and put forward the suitable range of IOB value (Inorganic/Organic Balance) for dyeing polyurethane. Moreover the processing parameters affecting the dyeing behaviors are tested systematically and analyzed.
