氨纶纤维分散染料染色性能探讨

Studies on the Dyeing Behaviors of Disperse Dyes for Polyurethane Fibers

通过对几种结构类型分散染料氨纶纤维上染率的测定 ,结合分散染料的IOB (无机 /有机 )值 ,探讨了分散染料结构与氨纶染色性的关系 ,系统测试了影响分散染料染氨纶的主要工艺参数 。

The relationship between the structures of disperse dyes and their dyeing behaviors is investigated by determination the exhaustion rate of disperse dyes with different chemical structures for polyurethane fibers and their IOB values (Inorganic/Organic Balance) After the main process parameters affecting the dyeing behavior are tested systematically, the optimal process condition is put forward
