[0003] The utility model solves the technical problems of prior art, and provides a foldable filter cloth.

[0004] In order to solve the above technical problems, the utility model discloses a foldable filter cloth, including upper fiber composite layer, base cloth layer and lower fiber composite layer, wherein the upper fiber composite layer is a blended layer of PTFE fiber and PPS fiber, the base cloth layer is a PTFE fiber layer, and the lower fiber composite layer is a blended layer of PET fiber and 4080 fiber.

[0005] In the utility model, the PPS fiber adopts 1.2D fiber.

[0006] In the utility model, the PTFE fiber adopts 1.0D fiber.

[0007] In the utility model, the PET fiber adopts 2.0D fiber.

[0008] In the utility model, the 4080 fiber adopts 1.5D fiber.

[0009] Beneficial effects: the utility model adopts the blended layer of PTFE fiber and PPS fiber and the blended layer of PET fiber and 4080 fiber as upper and lower layers respectively, and after heat setting and hardening, it can be folded according to needs. BRIEF DESCRIPTION OF DRAWINGS

[0010] The above and / or other aspects of the utility model will become more apparent from the following detailed description of the utility model, taken in conjunction with the accompanying drawings.

[0011] Figure 1 It is structural schematic diagram.

[0012] In the drawing, reference numerals: 1, upper fiber composite layer, 2, base cloth layer, 3, lower fiber composite layer. DETAILED DESCRIPTION

[0013] Embodiment:

[0014] As Figure 1 The embodiment provides a foldable filter cloth, which comprises an upper fiber composite layer 1, a base cloth layer 2 and a lower fiber composite layer 3, wherein the upper fiber composite layer is a blended layer of PTFE fibers and PPS fibers, the base cloth layer is a PTFE fiber layer, and the lower fiber composite layer is a blended layer of PET fibers and 4080 fibers.

[0015] Specifically, the PPS fibers are 1.2D fibers.

[0016] Specifically, the PTFE fibers are 1.0D fibers.

[0017] Specifically, the PET fibers are 2.0D fibers.

[0018] Specifically, the 4080 fibers are 1.5D fibers.

[0019] In the embodiment, the upper fiber composite layer 1, the base cloth layer 2 and the lower fiber composite layer 3 are hardened through 40-degree heat setting, so that the foldable filter cloth is obtained.

[0020] The utility model provides a kind of foldable filter cloth's thought and method, the method and approach of specific implementation this technical scheme are many, above-mentioned only is the preferred implementation mode of the utility model, it should be pointed out, for the ordinary skilled in the art of this technology, under the premise of not departing from the principle of the utility model, still can make several improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the utility model.The components not specified in the embodiment can be realized by existing technology.
