Problems solved by technology

Although this technology improves the temperature resistance of the composite filter material, the addition of the antistatic agent will basically lose the electrostatic adsorption capacity of the finished filter material, and the overall filter material's ability to filter tiny dust particles will be weakened.
[0007] From the above, it can be seen that the structure improvement and material improvement technology of the existing filter cloth are mainly carried out for the physical strength, temperature resistance, acid and alkali resistance of the material, and the improvement of the overall filter cloth filtration performance mainly depends on the mechanical adsorption of different materials. superposition, and some technologies can also have negative effects

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] According to one embodiment of the present invention, figure 1 A schematic cross-sectional view of an air filter material 100 is shown. As shown in the figure, the air filter material 100 may include a blended brushed filter cloth made by blending a first polymer fiber and a second polymer fiber in a ratio of 1:1 10. The brushed surface of the blended brushed filter cloth 10 is sewn with nylon mesh 20 . According to another embodiment of the present invention, the nylon mesh 20 may also be a polytetrafluoroethylene filter mesh.

[0026] In order to achieve a better filtering effect, the aperture of the nylon mesh 20 (or polytetrafluoroethylene filter mesh) can be selected as 180-300 mesh.

[0027] According to an embodiment of the present invention, the first polymer fiber may be a single polyester fiber or a single acrylic fiber, or a...

Abstract

The invention discloses an air filtration material which is formed by stitching blended napping filter cloth and a nylon filter screen or teflon filter screen, wherein the blended napping filter cloth is formed by blended weaving of first polymer fiber and second polymer fiber at the ratio of 1:1; and a napping face of the blended napping filter cloth fits the nylon filter screen (or teflon filter screen). According to the manufacturing method of the air filtration material, low-cost and widely-applied polypropylene fiber, polyester fiber, etc. are selected, and a simple napping and stitching technological mode is adopted. The air filtration material can highly-efficiently adsorb small granular dust in the air and can be conveniently applied in various existing air-borne dust filtration units.

Description

technical field [0001] The present invention relates to an air filter material, more specifically, to a composite air filter material and a manufacturing method thereof. Background technique [0002] With the increasingly serious air pollution, in addition to researching more energy-saving and emission-reducing technologies, people also pay attention to finding ways to filter or purify air to reduce the impact of air pollution on health. Among them, there have been a lot of research and development of air filter materials. [0003] The air filtration equipment used in the existing industrial and commercial fields often uses various woven filter cloths and their products, such as filter cloths woven from polypropylene, glass fiber, polyester and blended fibers, and non-woven fabric weaving processes, such as meltblown, Compared with non-woven materials made by acupuncture, spunbonding and other processes, woven filter cloth has the characteristics of high strength, suitable ...
