METHOD FOR MANUFACTURING HIGH STRONG POLYESTER FOR INDUSTRY GREY YARM

摘要

A preparation method of high reinforced polyester industrial yarn mounting a circular draw pin roller(3) for controlling a temperature between 2 godet rollers(2,4) in the course of drawing a polyester yarn(1) in 2100 m/min, thereby drawing the polyester yarn is disclosed. The roller(3) is located in the position that is (M) between the point(P) where the yarn(1) is dropped on the godet roller(2) and the point(Q) which the roller(3) is in contact with the yarn(1) is 30-250mm. Thereby, it is possible to enhance workability.
