阳离子染料可染丙纶的结晶特性和形态结构研究

Study on the crystallization properties and morphological structure of cationic dyeable polypropylene fibers

将自制可染剂通过与聚丙烯共混纺丝生产的阳离子染料可染丙纶进行 X射线衍射分析和SEM观察研究。结果表明 :可染丙纶的晶粒尺寸 ( L110 )越大 ,其染色性能越好 ;可染剂与聚丙烯有一定的相容性 ,并且能均匀分散在聚丙烯中 ,使纤维上染率达到 90 %以上。

The crystallization properties and morphological structure of the cationic dyeable polypropylene fibers were studied by X-ray and SEM. The results showed that the larger crystal size is, the better dyeable properties of the fibers are. The dyeable agent was compatible with polypropylene and can be uniformly scattered in polypropylene resin, which ensured dye-uptake up to above 90%.
