Monofilament multifilament filter bag It is a surface filter fabric structure, which is shaped at high temperatures to prevent the expansion of filter pores during the filtration process. Therefore, it has a filtration grade, captures impurities on the surface of its filter material, and the filter bag can be repeatedly cleaned and reused. Needle felt filter bag Using the principle of depth filtration, needle felt cloth filter bags can filter out a large amount of solid or gel soft impurities. 100% pure fiber is used to create a three-dimensional filter layer by acupuncture method. Larger particles of impurities are captured on the surface of the filter bag, while fine particles are captured in the deep layer of the filter material, so it is a depth filter material. Filtration accuracy from 1-200 m. Needle felt filter bag has the advantages of low cost, large filter area, and small pressure difference, and is the most economical filtration method. The surface of the needle-felt filter bag is specially treated to ensure that no fibers fall off, but the filter bag cannot be cleaned and reused. Melt blown non-woven filter bag A deep non-woven filter material composed of multiple layers of polypropylene microfibrils. The inner layer is composed of polypropylene needle felt cloth, which has a primary filtration function; the middle layer is composed of polypropylene microfibril melt-blown non-woven fabric, the filtration accuracy is from 1-200 m, and the filtration efficiency is 98%; the outer layer is composed of polypropylene Composed of spun-bond fibers, it has the advantages of high strength and no fiber shedding. Melt blown non-woven filter bag filtration accuracy: 1, 3, 5, 10, 25, 50, 100 m.
