Description

Technical Field

[0001] The invention relates to the technical field of filter materials, in particular to a mixed woven polyester high-strength filter material. Background Art

[0002] Through patent search, it was found that the publication number is CN208448819U, which discloses a high-strength polyethylene filter material. The high-strength polyethylene filter material includes a first fiber layer, a high-temperature resistant adsorption layer, a second fiber layer, a high-strength layer and a base fabric layer. Since the hot melting temperature of the polyethylene fiber itself is low, it can be singed and calendered at a lower energy consumption. The surface of the filter material is more likely to form a microporous structure, so the obtained filter material has better filtering accuracy.

[0003] During the use of existing high-strength filter materials, exhaust gas passes through the inner cavity of the filter material, and dust in the exhaust gas is blocked in the inner cavity of the filter material. The layers of the filter material are stuck together, and there is little space for dust storage, causing dust to adhere to the surface of each layer, resulting in a greatly reduced exhaust gas pass rate, thereby resulting in poor exhaust gas filtering effect. In order to solve the above problems, this application proposes a blended polyester high-strength filter material. Utility Model Content
