Polyester coated needle felt

The surface of polytetrafluoroethylene (PTFE) film is smooth and resistant to chemical substances. The double anti filter bag covers it onto the surface of the polyester needle felt, serving as a one-time dust layer, trapping all dust on the surface of the film, achieving surface filtration. Additionally, due to the smooth surface of the film, good chemical stability, non aging, and hydrophobicity, the dust trapped on the surface is easy to peel off, while improving the service life of the filter material.

Polyester room temperature needle punched felt is a fine fiber cloth made by using non-woven needle punched technology, which uses fibers arranged in a staggered manner and evenly distributed gaps. The surface of the needle punched felt produced by polyester short fibers and twisted polyester yarn is treated by hot rolling, singeing, or coating to make its surface smooth and not easily blocked by dust. This filter material has a large porosity, good breathability, wide range of uses, strong chemical stability, and can not only filter room temperature gases, Moreover, it can filter corrosive gases containing acids and alkalis, as well as filter water and oil. It is an ideal filtering material for fields such as room temperature conditions and liquid-solid separation

1. Polyester needle punched felt uses interlaced and evenly distributed short fibers to filter air, with a porosity of 70%, which is twice that of woven filter cloth.

2. High dust removal efficiency and low gas emission concentration.

3. The surface of the polyester needle felt has been hot-rolled, singed or coated, and is flat and smooth, not easily blocked, deformed, easy to clean, and has a long service life.

4. The anti-static needle felt has the function of anti-corrosion, preventing electrostatic discharge of blast furnace gas and cement plant coal grinding bag dust collection, and exporting static electricity.
