PRODUCTION OF SYNTHETIC FIBER

摘要

PURPOSE:A specific applicator is used and the application is effected at a specific position to enable uniform and effective application of another fiber-treating agent without adverse effect of the finishing oil. CONSTITUTION:The finishing oil is applied to the yarn which has been cooled in the cooling zone 2 at the position where the yarn 3 is running downward. Then, the yarn is turned several times around the taking-up roller 5, then allowed to run upward and another liquid fiber treating agent is applied on its way of upward running. The application guide 7 has a nozzle on the lower side and a flat face that can uniformly contact with the yarn on the upper part.
