Preparation method of hydrophilic conductive polyphenylene sulfide fiber

Abstract

The invention provides a preparation method of hydrophilic conductive polyphenylene sulfide fibers, and belongs to the technical field of textile fiber preparation. The preparation method comprises the following steps: carrying out melt blending on a conductive auxiliary agent, a hydrophilic auxiliary agent and polyphenylene sulfide resin by utilizing a double-screw extruder, and then spinning to obtain the hydrophilic conductive polyphenylene sulfide fiber. According to the invention, a twin-screw multi-zone high-pressure high-shear interactive in-situ grafting technology is utilized, fiber preparation is completed by one step through melt blending and spinning forming, a hydrophilic auxiliary agent is loaded on a conductive auxiliary agent, the dispersity of the conductive auxiliary agent and the compatibility with a PPS matrix are improved, the uniformly dispersed conductive auxiliary agent can form a cross-linked network structure in the PPS matrix, and the conductive performance of the PPS matrix is improved. The conductive performance and the hydrophilic performance of the polyphenylene sulfide fiber are improved.
