氨纶分散染料低温染色的研究

A Study of Dyeing Technology on Polyurethane at the Lower Temperature with Disperse Dyes

通过新型助剂的研究和应用 ,使氨纶能在比较低的温度下进行染色 ,并得到较为满意的染色效果 ,同时在 60℃条件下 ,测定了C .I分散红 60上染氨纶的平衡吸附等温线 ,分析了分散染料在氨纶上的吸附机理。

In this paper,through the research and application of a new kind of dyeing auxiliary,the polyurethane fiber can be dyed at the lower temperature with the disperse dyes,and the satisfactory dyeing effects are obtained,at the same time,the absorption isotherms of C.I.Disperse Red 60 on PU fiber at the 60℃ was measured.The mechanism of absorption was also analyzed.
