HIGH-PERFORMANCE POLYPHENYLENE SULPHIDE FIBRE STRUCTURE, PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

A high-performance polyphenylene sulphide fibre structure, a preparation method therefor and a use thereof. The polyphenylene sulphide fibre structure is a woven fabric formed from polyphenylene sulphide fibres with a cross-sectional diameter of 0.1-12 μm. The maximum pore size of the polyphenylene sulphide fibre structure is no more than 20 μm. The polyphenylene sulphide fibre structure has the characteristics of high air tightness and good hydrophilicity, and also has the characteristics of a simple process, being energy saving and causing no pollution to the environment, and can be used in membranes, high-temperature liquid filtration and insulating materials.
