Bag filters are in general frequently used for dust removal in industrial applications. We make filter bags to fit most styles and types of bag houses and other dust collection systems.

We make filter bags to fit most styles and types of bag houses and other dust collection systems.  Filter bags come in a wide range of fabrics, coatings, finishes, sizes and configurations.Medias are available in various fabric weights and treatments such as singed, glazed, PTFEmembrane, anti-static,  acid resistant and more

We provide PPS needle felt for dust collecting in cement plants, iron and steel plants, power plants, chemical plants, etc, the weight from 400g/sqm to 750 g/sqm can be customized. We can finish them with water - oil repellent treatment, PTFE membrane treatment, PTFE pregnant treatment, etc.

Needle felt is a kind of non-woven filter fabric specially used for dust collector filter bags. It is a major filter material for industrial air filtration and dust removal. The needle felt is made of randomly arranged fibers needle punched on the scrim fabric, after that the fibers are close-knitted to form a tortuous three-dimensional stereo-structure, which is different from the traditional woven filter cloth composed of warp and weft yarns. It makes dust particles adhere to the surface of the filter material and form an initial layer of dust ( Filter cake), with the remarkable characteristics of small pore size, high filtration efficiency and low air resistance, greater air permeability and excellent dust particle capture.

The chemical name of PPS is polyphenylene sulfide. It is a white material with excellent thermal stability. Although it will burn when it is placed in a flame, the combustion will stop immediately when the flame is removed. It will show a yellow-orange flame when it burns, and a trace of black will be generated. Soot does not fall off the burned material, and forms residual coke, showing low flame spread and smoke density. The limiting oxygen index is 34-35. The most commonly used fineness is: 2.2 dtex. Other finenesses are: 1.1 dtex 1.7 dtex 3.0 dtex and so on. The most commonly used lengths: 51mm and 60mm. The working temperature is 130～160℃, the short-term working temperature is 190℃, and the melting point is 285℃. In addition, the oxygen content of the fiber should be less than 8% during normal use. The higher the oxygen content, the use temperature should decrease accordingly.

Since the white fiber is produced by the film splitting method, the dispersion in fineness is relatively large, generally from 2dtex to 10dtex. The brown fiber is wet-spinned, so the fiber fineness is relatively fixed. At present, it is 3.3dtex in foreign countries, and the single yarn strength is generally above 4dtex in China. The length is generally 51mm~75mm. The melting point of PTFE is 327 °C, and it can be used for a long time at a high temperature of 260 °C, and the instantaneous use temperature can exceed 300 °C. PTFE cannot burn, and its limiting oxygen index reaches 95%. The strength is low and the breaking elongation is small. The breaking strength of the imported brown fiber is only 1.9cn/dtex, while the strength of the white imported fiber basically does not exceed 4cn/dtex. The friction coefficient is low, so the dust is easy to fall off on the surface of the filter material. The surface tension of the fiber is large, and it has good water repellency. The fiber is finer, the filtration efficiency is average, and the filter material has a weight of 750-800g. The textile performance is not good, the cohesive force is low, and static electricity is easily generated in the fiber spinning process.
