[0002] After searching, the patent number is CN216170665U, which is an anti-static blended polyester high-strength filter material. It is woven with No. 2 polyester fiber line and No. 2 nylon fiber line to improve the overall density of the No. 2 surface layer, while improving the strength of the No. 2 surface layer and extending the overall service life. The No. 1 anti-static fabric layer makes the whole have anti-static properties, the No. 2 anti-static fabric layer improves the stability of the anti-static performance, and the No. 1 dust-facing layer and the No. 2 dust-facing layer improve the overall filtering performance.

[0003] For the above-mentioned filter material, an antistatic cloth layer is compounded on its polyester filter material layer.
