Description

technical field

Background technique

The hot drawing process is an operation unit that plays a key role in the control of the final fiber properties during the processing of chemical fiber filaments, especially fully drawn chemical fiber filaments. The processing of chemical fiber filament tow is usually drawn by hot roll; while the monofilament is often drawn by liquid bath or hot plate. Hot roll drafting can achieve high-speed production, but there are disadvantages such as high energy consumption, slow heat transfer, the need for multiple windings, and the inevitable temperature difference between the air and the roll surface between the rolls; while the liquid bath or hot plate drafting is limited by heat transfer. Due to the characteristics of the medium, the heat treatment efficiency is low, and it is difficult to achieve high-speed production.
