Problems solved by technology

[0007] According to the above, due to the poor oxidation resistance of the polyphenylene sulfide fiber of the air purification filter material in the existing scheme, thermal shrinkage will occur above 200°C, and the mechanical properties will be affected
At the same time, the existing polyphenylene sulfide non-woven fiber is relatively thick, and the filter material has a relatively large pore size. For the fine filtration of PM2.5 particles, the filtering effect cannot meet the requirements. The present invention proposes a high-temperature resistant ultra-fine Composite fiber air-purifying textile and preparation method can effectively solve the above-mentioned technical problems

Abstract

The invention relates to the field of air-purifying filter materials, and discloses a high-temperature-resistant ultrafine composite fiber air-purifying textile and a preparation method thereof. The preparation process includes the following preparation process: (1) mixing polyphenylene sulfide superfine fibers and polytetrafluoroethylene fibers to prepare the dust facing surface; (2) making the middle layer of thick fibers in polyphenylene sulfide; Phenylene sulfide coarse fiber is made into clean air surface; (4) compound pre-acupuncture is carried out according to the position sequence of middle layer, polyphenylene sulfide base cloth, middle layer and clean air surface to obtain pre-needle punched felt; (5) The dust-facing surface and the middle layer of the pre-needled felt are laminated for hydroentanglement, and then dried, heat-set and heat-calendered to obtain a high-temperature-resistant ultrafine composite fiber air-purifying textile. The air-purifying textile prepared by the invention forms a layer of gradient structure from the dust-facing surface to the air-cleaning surface through the mixing and matching of different fibers, thereby improving the filtering effect and temperature resistance.
