Method for continuous production of polyester weft yarn for tire cord

Nylon -6,6 monofilaments for precision wovens

A process for the manufacture of a crimped polyester yarn obtained from a polyester partially-oriented yarn comprising fabricating a partially-oriented polyester yarn by a high-speed process, cooling the partially-oriented polyester yarn, cold drawing the cooled yarn, and subjecting the cold drawn polyester yarn to a thermal treatment under tensionless conditions or under controlled overfeed conditions.

Crimped polyester-yarn from cold drawn polyester-POY-yarn and process

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.degree. to 250.degree. 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.
