摘　　要：成孔剂(HA)与聚丙烯(PP)共混纺丝,具有很好的染色性和吸水性,是多功能化改性丙纶。本文采用DSC技术研究了HA-PP改性丙纶的等温与非等温结晶行为,并通过偏光显微镜考察了它的结晶形态。实验结果表明HA在PP结晶过程中起异相成核作用,因而改变了PP的结晶速度、球晶形态、晶粒大小及分布。HA-PP is a multifunctional modified polypropylene fibre,that had good dyeability and waterabsorbability. DSC and PM are used as investigated. The result shows that the hollow agent (HA) acted as heterogeneous nucleat and which changes the crystallization rate,crystal morphology .crystal grain size and distribution of PP.
