Novel tensioning heat-setting heating device

Abstract

The invention discloses a novel tensioning heat-setting heating device. The device comprises a preheating area and a heat-setting area which are sequentially formed; the preheating area comprises a plurality of pre-heat-setting rollers; the heating area comprises a plurality of heat-setting rollers; the pre-heat-setting rollers and the heat-setting rollers are sectional electromagnetic induction heating rollers; two continuous heating areas formed in the middle and discontinuous heating areas formed in two sides are distributed in the sectional electromagnetic induction heating rollers. According to the novel tensioning heat-setting heating device, fiber bundles are processed by heat-setting through the sectional heating rollers; the temperature of the continuous heating areas and the discontinuous heating areas is individually controlled, so that the fiber bundles can be kept in stable and uniform temperature, and as a result, the heat-setting effect can be improved, the fiber structure can be improved, and the fiber quality can be increased.

Description

technical field [0001] The invention relates to the field of industrial spinning preparation equipment, in particular to a tension heat setting device used for the production and processing of high-performance polyphenylene sulfide fibers. Background technique [0002] During the forming process of synthetic fibers, the spinning melt is extruded from the spinneret hole, and after solidification, after the subsequent stretching process, its supramolecular structure has been basically formed, but because some molecular segments are in a relaxed state, while others Some chain segments are in a tense state, so that there is uneven internal stress inside the fiber, and the crystal structure in the fiber also has many defects, which need to be partially or completely eliminated in the subsequent heat treatment. In the process of fiber post-processing, tension heat setting devices are usually used to improve the fiber structure, so as to obtain fiber products with good quality. At...
