The non-woven filter bag is a kind of liquid filter bag. The main material is the special liquid filter material made abroad with the highest standard in the same industry or produced by the same manufacturer in the domestic wholly-owned factory. The filtering surface of the filtrate is treated with special singeing, which not only effectively prevents the fibers from decontaminating the filtrate, but also avoids the excessive blockage of the filter holes caused by the traditional rolling treatment and shortens the life of the liquid filter bag. All raw materials are pure white without any special bleaching and dyeing treatment, which fully complies with environmental protection standards. Moreover, due to the three-dimensional filter layer of the needled felt, when the liquid flows through the needled felt, the particles will be retained in the liquid filter bag due to the deep filtration mechanism. The inner wall surface and deep layer have high collection efficiency for solid or colloidal particles. The uniform thickness, stable open porosity and sufficient strength of the needle-punched felt make the liquid filter bag stable in efficiency and longer in use.

The bottom, side and collar connection methods of the liquid filter bag are all welded by hot-melt method. The traditional seam liquid filter bag has side leakage problems caused by pinholes and uneven material, and fiber shedding problems. The hot melt welded liquid filter bag is solved, and the high-precision wireless seam liquid filter bag adopts digital co-located multi-point welding equipment to ensure that the welding of each point remains the most firm and consistent. To ensure that the liquid filter bag is not affected by other production accessories, and to ensure the consistency of the material of each liquid filter bag. Suitable for more demanding industrial use.
