| 摘 要： | 本文叙述了应用正交试验法,控制涤纶POY伸度。研究结果发现,影响涤纶POY伸度的四个因素的次序为:纺速>熔体温度>侧吹风风速>POY纤度;而影响涤纶POY伸度不匀率CV值的四个因素为,熔体温度>POY纤度>侧吹风风速>纺速,

ELONGATION CONTROL OF POLYESTER POY AND ITS CV VALUE |
| |
| Abstract: | The control of elongation of polyester POY is studied by the orthogonal optimization experiment, the result shows the order of the four influential factors according to their contributions is spinning speed>melt temperature>cooling air speed>denier of POY, but in the case of CV value of elongation the order is changed to melt temperature>deneir>cooling air>spinning speed. |
