Document Type and Number:
WIPO Patent Application WO/2020/177322
Kind Code:
A1
Abstract:
A spinning method and apparatus. The method and apparatus are suitable for the production of polyarylene sulfide fibers having relatively high glass transition temperature. By adding the fibers into an oil bath storage tank, uniform heating during fiber drawing can be maintained and the heating temperature can be precisely controlled; the damage to equipment and to the quality of the fibers in an oil bath tank due to high temperature transmission of a heating medium is avoided, and the problem of insufficient utilization of the heating medium caused by the reduction of starting and stopping efficiency and the drastic change in the flow of the heating medium when the equipment is started or stopped is avoided.
