摘要
在降低聚酯黏度、提升负荷的条件下,通过提高后纺拉伸倍率,拉伸温度等来保证断裂强度等品质指标,改善了纤维的拉伸性能。原丝倍半伸长率是确定纺丝工艺调整方向和幅度的重要依据。
Under the conditions of reducing the polyester viscosity, raising the production load, by improving the afterspinning stretching ratio and stretching temperature, the quality indexes such as breaking teed. The fiber drawing performance was improved. EYS1.5 was the key basis of spinning and direction,amplitude moducation. tenacity etc were guarantechnology determination
