Abstract:
The present invention discloses a high-performance PPS fiber structure and production method and use thereof. The high-performance PPS fiber structure is woven fabric made from PPS fibers in 0.1 to 12 μm cross sectional diameter, and the maximum pore size of the PPS fiber structure is 20 μm or smaller. The PPS fiber structure disclosed in the present invention has the advantages of high gas impermeability and good hydrophilicity, also has the advantages of simple process, low energy consumption and zero environmental pollution, and can be used in diaphragms for electrolytic apparatuses, high-temperature liquid filter materials and insulating materials.

Claim (Index 10):
A method for producing the high-performance PPS fiber structure according to  claim 1 , characterized in comprising the following steps:\n (1) cotton spinning process: processing PPS fibers in 0.1 to 12 \u03bcm cross sectional diameter by opening and cleaning, carding, drawing, roving, drafting the roving to obtain PPS single yarns with yarn count equal to 20 to 60 s and twist factor \u03b1 equal to 200 to 310, processing the PPS single yarns by winding, doubling, twisting and thermoforming into PPS yarns with ply number equal to 1 to 6; (2) weaving process: processing the obtained PPS yarns by warp beaming, drafting, reeding, and weaving, to obtain PPS woven fabric with cover factor equal to 2400 to 2900; (3) post-finishing process: processing the obtained PPS woven fabric by scouring, water washing, drying, and thermoforming at 180 to 200\u00b0 C.; (4) hydrophilic treatment process: processing the thermoformed fabric by plasma hydrophilic treatment and/or sulfonated hydrophilic treatment, to obtain a finished product finally.
