| titleOfInvention | Density gradually-changed PPS fiber filtering material and filtering bag |
| abstract | The invention belongs to the technical field of PPS filter felts, and particularly relates to a PPS fiber filter material with gradually-changed density, which comprises a filter material layer, wherein the filter material layer is prepared by a first surface layer, a base cloth layer and a second surface layer through needling; the thickness ratio of the first surface layer to the base fabric layer to the second surface layer is (3-10): (1-2): (5-10), the first surface layer is a micro-denier PPS fiber layer, a fine-denier PPS fiber layer and a medium-denier PPS fiber layer from outside to inside in sequence. According to the PPS fiber filtering material with gradually-changed density, the preparation process and the filtering bag, the first suture line and the second suture line in the filtering bag body are one or more of the PPS fiber line, the PTFE fiber line and the 316L metal fiber line, so that the high-temperature resistance effect of the filtering bag body is further improved, and the metal fiber has unique performance and wide application as organic and inorganic fibers. The metal fiber has good electric conduction, heat conduction, magnetic conduction and high temperature resistance, and the manufacturing method is simple and the cost price is low. |
