PET复合中空三维卷曲纤维弹性的提高

Elastic improvement of PET composite hollow 3D crimp fiber

针对生产的PET复合中空三维卷曲纤维弹性低问题,对影响弹性的特性黏度、冷却条件进行了优选,提高了PET复合中空三维卷曲纤维弹性,保持了良好的手感,取得了显著的经济效益。

According to the low elastic problem of the PET composite hollow 3D crimp fiber,the factors that have effect on the elastic such as intrinsic viscosity, cooling condition was optimal selected and improved. The elastic of PET composite hollow 3D crimp fiber was improved,the handle was kept, obvious economic benefit was achieved.
