聚酯/聚酰胺双组分复合超细纤维染色性能研究

Dyeing Properties of PES/PA Blcomponent Supermlcrofibre

系统研究了聚酯／酰聚胺双组分超细纤维染色性能，测定了纯化及商品化的分散染料的上 染速率曲线、半染时间、扩散系数、平衡吸附量及深染性，并与几种直接纺丝法生产的超细纤维作了对 比。

In this paper,the dyeing properties of PES/PA bicomponent supermicrofibre have been studied. The dyeing rate curves,the half-dyeing time, the diffusion coefficient,the sorption at equilibrium and the properties of deep dyeing are also calculated and discussed with the purified dye and commercial dye. The dyeing properties of the bicomponent supermicrofibre have been compared with those of the monocomponent supermicrofibres.
