Embodiment

[0087] Hereinafter, examples are given to describe the present invention more specifically, but the present invention is not limited to these examples.

[0088] The volume of the oil bath is set to 300L, and the solvent used is set to water.

[0089] In the control group, the figure 1 In the way shown, add liquid medium (a mixture of water and finishing agent) into the lower tank and heat it directly. After the temperature of the liquid medium in the lower tank reaches 98°C, the liquid medium is pumped to the oil bath tank through a water pump. Inside, the maximum flow rate of the pump is 16m 3 / h, power 4Kw, and maintain the stability of the temperature of the liquid medium in the oil bath through circulation.

[0090] In the experimental group, the figure 2 In the way shown, the temperature of the liquid medium in the low-temperature tank (composition of the liquid medium in the control group is the same) is controlled at 70°C, while the temperature of the liquid medium...

Abstract

The present invention relates to a kind of spinning method and device, more specifically, relate to the production method and device of the resin with higher glass transition temperature, especially polyarylene sulfide fiber, the present invention adds oil bath storage tank, It can keep the heating uniform and the heating temperature accurately and controllable in the fiber drawing, avoiding the damage to the quality of the equipment and the fiber in the oil bath due to the high temperature transmission of the heating medium, and avoiding the reduction of the start-stop efficiency and heating when the equipment starts or stops. The problem of insufficient utilization of the heating medium caused by the drastic change of the medium flow.

Description

technical field [0001] The invention belongs to the field of production methods of chemical textile products, in particular to a production method and production equipment of fiber materials, more specifically, to a resin with a relatively high glass transition temperature, especially a production method of polyarylene sulfide fibers and device. Background technique [0002] Polyarylene sulfide (PAS) resin has excellent heat resistance, shielding properties, chemical resistance, electrical insulation, heat and humidity resistance and other properties suitable for engineering plastics. As a typical representative of polyarylene sulfide, polyphenylene sulfide (PPS) is widely used in various product processing. [0003] Among them, PPS fiber is a new type of special plastic fiber, which is made of polyphenylene sulfide resin (PPS) by conventional melt spinning method, and then post-processing at high temperature. There are filaments, monofilaments, Yarn, staple fiber, etc. S...
