为了克服与使用分散剂有关的一些环境问题，以前已经合成了四种暂时可溶解的分散染料，并对其进行了表征，用于无分散剂的聚酯染色。本文研究了这些染料在涤纶织物上的染色和牢度特性。研究发现，保证适度水解速率的最佳pH值为5，这使得暂时溶解的分散染料可以在不使用分散剂的情况下成功地应用于聚酯。染色槽在染色过程中保持稳定。染料在涤纶上表现出良好的染净性和牢度。
In an effort to overcome some of the environmental problems associated with the use of dispersing agents, four temporarily solubilised disperse dyes had previously been synthesised and characterised for use in dispersant-free polyester dyeing. In this paper the dyeing and fastness characteristics of these dyes on polyester fabrics have been examined. It was found that the optimum pH to guarantee a moderate rate of hydrolysis was 5, which allowed temporarily solubilised disperse dyes to be successfully applied to polyester without the use of dispersants. The dyebath remained stable during the dyeing procedure. The dyes exhibited good levelling and fastness properties on polyester.
