CHDM改性共聚酯的纺丝工艺研究

STUDY ON SPINNING TECHNIQUE OF 1,4-CYCLOHEXANE DIMETHANOL MODIFIED POLYESTER

利用不同CHDM含量的共聚酯切片制得 1 1 0dtex/ 36f纤维 ,对切片的干燥工艺、纺丝工艺、拉伸工艺条件进行了研究。结果表明 ,随改性成分CHDM加入量的增加 ,DT丝强度下降 ,断裂伸长率下降 。

With Polyester chips modified by 1,4-cyclohexane dimethanol (CHDM) being used, 110 dtex/36f fibers can be obtained.And the technique of chip drying, spinning and drawing were stadied.The results showed that the strength of DT would decreased including the breaking strength and the boiling water shrinkage with the content of CHDM being decreased.
