Manufacturing method of polyester yarn by high speed spinning

摘要

The present invention by installing a heating pipe for heat treatment during the production of polyester yarn by a high-speed spinning method of more than 5,000m / min spinning speed in two stages to reduce the radiation tension and increase the elongation to prevent the occurrence of shear and trimming It is to be able to produce a polyester yarn of excellent quality, which is composed of a heating pipe divided into two stages, the first stage of the internal heating temperature to 120-140 ℃ and the length of 50-80 ㎝, The second stage consists of internal heating temperature of 180-200 ℃ and length of 80-100cm.
