超细丙纶专用切片和高速纺丝工艺研究

Study on the chip and high-speed spinningfor superfine polypropylene fibers

采用化学改性 ,制造出熔融指数为 39～ 41g/10 min、相对分子质量分布更窄的超细丙纶高速纺专用料 ,并通过对纺丝速度、组件、油剂等工艺进行调整 。

The polypropylene chip which has narrower molecular weight distribution and the MI value 39～41 g/10 min is made by chmical modification.The spinning speed,spinning unit and spinning finish are adjusted to improve the high-speed spinning process.
