ECDP熔体喷丝头组件压力降研究

Study on the ECDP Melt Spinnerette Unit Pressure Descension

喷丝头组件是纺丝成形的主要部分 ,喷丝头组件压力降大小则表征了纺丝熔体的流变性和可纺性 ,同时也从侧面反映了喷丝头组件结构的合理性。本文通过对喷丝组件压力降的试验、解析 ,揭示了喷丝头组件压力降初期分布和升压的 ECDP熔体变化特点 ,为喷丝头组件结构改进和纺丝工艺的完善提供了参考依据。

Spinnerette unit is the main part of the spinning-formation process.The quality of the spinnerette unit affects the spinning process directly.The degree of the spinnerette unit pressure descension reflects rheological and spinnability of the unit,as well as the reasonableness of the spinnerette unit construction from the side.This paper shows the primary distribution of the spinnerette unit pressure descension and the character of the pressure ascending through experiment and analysis of the spinnerette unit pressure descension,to provide a reference basis for the modification of the spinnerette unit and the promotion of the spinning process.
