摘要

spinning polyester yarn at a below 5000 m/min spinning speed; cooling in cooling bath of 400-500 mm length; heat-treating a heat pipe of 200-300≦̸C; passing ever the first godet roller; and heat-stabilizing in the second godet roller at the same speed as the of 1st godet roll at 100-200≦̸C. The process, the production reduces cost.
