纺丝及纤维成形的机理(Ⅳ)

Mechanism of Spinning and Fibre Formation

本文以结晶性极好的成纤高聚物等规聚丙烯为例,对其熔融纺丝中结构的形成进行了讨论,对纤维成形过程中结晶结构与卷绕张应力、平均分子量、纤维性能的关系等结合实验数据进行了细致的阐述。

The fibre forming isotactic polypropylene with excellent crystal-lizability is taken as example to discuss its structure formation duringmelt spinning. Combining with the experimental data, the authorexpounds the relations of crystalline structure to the winding tensilestress, average molecular weight and fibre properties etc. in the fibreforming process.
