摘　　要：通过对不同纺丝速度及拉伸条件下涤纶ＰＯＹ中空丝的中空度的测定，分析探讨了影响涤纶ＰＯＹ中空度的原因。结果表明：在试验范围内，随着纺丝速度的提高，涤纶ＰＯＹ的中空度变小；冷拉伸后，涤纶未拉伸丝的中空度变大，热拉伸则相反；随着拉伸倍数的提高，涤纶未拉伸丝的中空度有所下降。The hollowness of PET POY in different spinning velocities and drawing conditions was measured,and the affecting factors were analyzed and discussed.The results showed that in test zone,with the spinning velocity increased,hollowness of the hollow polyester POY decreased.Hollowness of the hollow polyester UDY increased after cool drawing,decreased after heat drawing, and was down a little while increasing drawing ratio.
