【摘要】 用生产普通型聚酯工业丝的设备,在工业化生产的条件下,生产具有良好尺寸稳定性的高性能聚酯工业丝。对生产过程中的固相缩聚切片黏度控制、喷丝板的选择、喷丝头拉伸、拉伸和定型等工艺进行了较为系统的试验优化,探索总结出了较为理想的解决方案,并成功生产了定负荷伸长(4.0cN/dtex)达5%左右、干热收缩率(177℃,1min)为4%～5%的高性能聚酯工业丝。更多还原

【Abstract】 Based on the equipment for producing conventional polyester Industrial yarn, under the conditions of industrial production, to produce high performance polyester industrial yarn with good dimension stability is selected as a target for this study. How to control the viscosity of upgraded chips, how to select right spinneret and how to set the proper parameters of drawing & heat setting have been systematically investigated, and a successful solution to produce high performance polyester industrial yarn with the EASL(4.0cN/dtex) around 5% and hot air shrinkage (177℃,1 min) from 4% to 5% has been reached.更多还原
