摘要(Abstract):

喷丝板孔径的大小影响POY的拉伸性能和拉伸应力的变化。后拉伸倍数低和应力波动大是造成随机性僵丝和毛丝的主要原因之一,对染色性亦有影响。文中提出了根据剪切速率计算高速纺喷丝板孔径的方法,并以十五家工厂的资料进行验证。
The hole size of spinneret influences the POY's drawing performance and stress in drawing, the low post-drawing ratio and strong fluctuation of stress are the main causes of random tight spots and naps in the yarn also the uneven dyeing. The method for calculating the hole size cf high speed spinning spinneret on the basis of shear rate is presented which has been examined in 15 factories.
