| 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。

| Abstract: | Under the conditions of reducing the polyester viscosity,raising the production load,by improving the after-spinning stretching ratio and stretching temperature,the quality indexes such as breaking tenacity etc were guaran-teed.The fiber drawing performance was improved.EYS1.5was the key basis of spinning technology determinationand direction,amplitude moducation. |
