PRODUCTION OF POLYESTER FIBER

摘要

PURPOSE:To provide a production method of polyester fiber capable of obtaining packages with favorable appearance, seldom causing breakage of single yarn or thread during its high speed manufacturing process at a spinning speed of >=3000m/min. CONSTITUTION:In conducting a high-speed manufacturing of polyester fiber at a spinning speed of >=3000m/min, the fibers are oiled with 0.2-1.0wt.% lubricant (based on the fibers) which has 0.35-0.40 coefficient of dynamic friction (fiber/metal) and 20.0-25.0g fiber/fiber static frictional force.
