染料在共混丙纶中的吸附和扩散

Absorption and Diffusion of Dyes in Blended Polypropylene

通过采用添加少量烯烃类高聚物的方法,制得可染共混丙纶,对其染色速度和染色平衡进行了研究。研究结果表明,染色速度与染色温度、染料结构有很大的关系,染色的等温吸附线属于Nernst型。

Dyeing rate and equilibrium of polypropylene blended with a little olefin polymer additive are studied. The result shows that dyeing rate is closely related with dyeing temperature and dye structure, isothermic absorption curve belongs to Nernst.
