Background

Filter cloths are the most widely used filter media in industry. The filter cloth is divided into a textile filter cloth and a non-textile filter cloth. Woven filter cloths are typically woven from three yarns of different types, monofilament, multifilament and staple. The monofilament is generally a single filament drawn by synthetic fiber, is hard, has small weaving density and large pores, and is easy to leak during filtration; the multifilament is formed by twisting more than two strands of raw filaments, the filter cloth consisting of the multifilament has good tensile strength and better interception performance to particles than monofilament, but has large resistance and easy blockage and crumpling when in use, influences the filtering effect and performance and has slightly poor residue unloading performance. The short fiber is twisted by natural cotton wool fiber or synthetic short fiber, and has good particle interception performance and good sealing performance due to the wool-like fiber, but has the defects that the pores are easy to be blocked by particles, and the cleaning and residue removal performance is poor.

The existing filter cloth has poor slag discharging performance and low water yield, which causes serious reduction of filtration yield; the phenomena of abrasion and crumpling are serious in use, and the service life is short; the deformation, tensile strength and compression resistance of the filter cloth are not ideal enough, when a medium with high corrosivity is filtered, the filter cloth is easily corroded by the filtering medium, the service life of the filter cloth is shortened, after the filter cloth is filtered, impurities on the filter cloth need to be removed through a scraper or a scraper due to the fact that the medium has high adhesion to the filter cloth and is not easy to clean, the wear resistance and strength of the filter cloth are not high enough, the filter cloth is often easily abraded during cleaning or filtering, the service life of the filter cloth is shortened, the filter cloth needs to be frequently replaced, and the cost is increased.
