Process for the production of a weft fiber of polyester-poy |
摘要 |
A process is disclosed for production of a heat-treated, coarse fiber of polyester-POY, whereby the fiber is first twisted and then continuously relaxed and tempered at a temperature from 130 DEG to 250 DEG C. to an extent from 20 to 55%. The slide-resistant fiber produced in this manner, displaying an elongation at break from 150 to 350%, a thermal shrink from +6 to -6% can be employed without further pre-treatment as weft yarn for tire cord webs.
