轮胎用PEN纤维与PET纤维性能研究

本文研究了PEN、PET 1100dtex、1670dtex纤维的原丝性能、捻线帘线性能、浸胶帘线性能。对浸胶后帘线进行了模拟硫化、蠕变、弯曲疲劳和粘合性能测试。浸胶PEN纤维帘线弯曲疲劳性能表现差之外,PEN纤维在原丝、捻线帘线、浸胶帘线保持更好的尺寸稳定性、更高的模量。PEN纤维浸胶帘线与橡胶具有良好的粘合性能。

The study of the performance of PEN fiber and PET fiber for tire usage

The yarn, twisting cord and dipped cord performance of 1100dtex and 1670dtex PEN fiber and PET fiber have been studied. For the dipped cord, the simulation curing, creep, Flex fatigue and adhesion performance have been tested. The results show that PEN fiber dipped cord Flex fatigue performance is worse than PET fiber, dimensional stability and modulus performance are better than PET fiber in yarn twisting cord and dipped cord. PEN fiber dipped cord has good adhesion performance with the rubber compound.
