Filter cloth and preparation method and application thereof

The invention belongs to the technical field of filter cloths, and particularly relates to a filter cloth and a preparation method and application thereof. The filter cloth is obtained by weaving polypropylene monofilament, the thickness of the filter cloth is 0.51 mm, the weight is 290 g/m , the warp density is 160 pieces/cm, and the weft density is 55 pieces/cm. The filter cloth has the following advantages that the capture effect on solids is good, the filtrate titer can be reduced to about 600 u/mL from 1,000 u/mL, and the softness is greatly improved to facilitate disassembling; the filtration speed is high, less blocking is caused, the filtration speed is stable, and plate and frame locating capacity is improved; residues are good in strippability, stretching does not exist, the dimensional stability is good, and waste caused by material adhesion in the disassembling and cleaning process is reduced or eliminated; the cleaning period can reach 20-30 days, washing waste water discharging and filter cloth
