Non woven filter cloth

Non woven filter cloth is made of polyester and polypropylene raw materials. It is processed by needle punching, combing, and adding a woven fabric layer at the center of the cloth. It is then subjected to double core treatment, air flow forming a net, needle punching, and composite into a cloth. After being pressed, the filter cloth has a three-dimensional structure. After heat setting and singeing, it is treated with a chemical oil agent on the surface to make the surface of the filter cloth smooth and evenly distributed. From the surface, the product has good density, smooth surface on both sides, and good breathability. It has been proven that this product can use high-strength pressure and has a filtration accuracy of up to 4 microns. The product can provide both polypropylene and polyester raw materials according to user needs. Practice has proven that non-woven filter cloth has better performance in plate and frame pressure filtration. It is used in dye factory plate and frame pressure filtration machines and in steel plant wastewater treatment plate and frame pressure filtration machines; The same excellent performance can be achieved on the plate and frame filter press for wastewater treatment in breweries and printing and dyeing factories, especially when filter paper needs to be clamped on the plate and frame filter press. This filter cloth has a fiber layer similar to that of the filter paper, and the filter paper is made of wood pulp and pulp that cannot be washed and is only used once. Non woven filter cloth can be combined with synthetic filter paper (cloth) without surface treatment, and the filtration accuracy can reach 1 micron. After surface treatment, it should be used separately and has good performance. It is easy to wash after use and can be reused after washing, with good economic value.
