The polyester needle felt filter bag uses high-quality polyester fine denier and large chemical fiber yarns, and uses advanced equipment to produce polyester (polyester) fiber needle punched filter felt. It can evenly and quantitatively mix a variety of fibers, and then use multiple mixing and carding units. The unit is conducive to the lamination and gradient transformation of different fiber layers between fiber webs. In addition to the advantages of high porosity, good air permeability, high dust collection efficiency, and long service life unique to ordinary felt filter cloths, polyester needle felt filter bags also have moderate temperature resistance levels, which can reach ℃ in an instant, and are resistant to acids and It has the characteristics of moderate alkali and very good wear resistance, so it is a widely used variety of felt filter materials.
