Description

Technical Field

[0001] The utility model relates to the technical field of dust collector filter materials, in particular to a base cloth structure for filter materials. Background Art

[0002] The core material of bag filters—the filter media—is typically composed of a base fabric layer and a fiber layer. The base fabric layer, a mesh structure composed of warp and weft yarns, provides support. During the filter media production process, the fiber layer is laid onto a web, then laminated with the base fabric layer. Needling / hydroentangling processes, such as spunlace, create a crisscross entanglement between the upper and lower fibers and the base fabric, resulting in a filter felt. After finishing, the filter media is obtained. The degree of entanglement between the base fabric and the fibers affects the strength and other properties of the filter media.

[0003] In the production of filter media, the mechanical properties of the filter media mainly rely on the entanglement between fibers and the entanglement between fibers and base cloth. Conventional base cloth is composed of smooth warp and weft yarns, and fibers can only be interwoven and entangled from top to bottom of the base cloth, resulting in limited entanglement effect. For some fibers with poor entanglement, the mechanical properties of the filter media obtained are low, especially the entanglement between the fibers and the base cloth is poor, and the fiber layer and the base cloth layer are easy to peel off. Utility Model Content

[0004] The purpose of the utility model is to provide a base cloth structure for filter material, which can effectively improve the mechanical properties of the filter material.

[0005] In order to achieve the above objectives, the solution of the present invention is:

[0006] A base fabric structure for filter material comprises a warp and weft yarn mesh and an unoriented linear structure. The unoriented linear structure is multiple and spaced apart on the warp and weft yarn mesh. One end of the unoriented linear structure is fixed on the warp and weft yarn mesh, and the other end diverges freely.

[0007] Furthermore, the warp and weft yarns of the warp and weft yarn mesh are made of one of polyphenylene sulfide, polytetrafluoroethylene, aramid, and polyimide; the non-directional linear structure is made of one of polyphenylene sulfide, polytetrafluoroethylene, aramid, and polyimide.

[0008] Furthermore, the non-directional linear structure has a curled structure.

[0009] Furthermore, the non-directional linear structure is in a spiral curled shape as a whole.

[0010] Furthermore, the diameters of the warp and weft yarns of the warp and weft yarns are 10-500 μm; the length of the non-directional linear structure is 1-50 cm and the diameter is 10-500 μm; and the distribution intervals of the non-directional linear structures on the warp and weft yarns are 1-10 cm.

[0011] Furthermore, the non-directional linear structure is fixed to the warp yarns, weft yarns or nodes of the warp yarns and weft yarns of the warp and weft yarn mesh.

[0012] Furthermore, the non-directional linear structure is fixed on the warp and weft yarns by weaving or adhering.

[0013] Furthermore, the lengths of the non-directional linear structures are not exactly the same.

[0014] After adopting the above technical solution, one end of the non-directional linear structure of the base cloth structure is fixed on the warp and weft yarns, and the other end can be entangled with the fiber layer when compounded with the fiber during the subsequent production of the filter material, thereby strengthening the connection strength between the fiber layer and the base cloth structure, so that the filter material formed after the compounding of the filter base cloth structure and the fiber layer has a higher entanglement effect, effectively improving the mechanical properties of the filter material made of the base cloth structure, so that the filter material has good spray resistance and the fiber layer and the base cloth are not easy to peel off from each other.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] like Figures 1 to 2 This embodiment presents a filter material structure that can be obtained using the base fabric structure of the present invention, including the base fabric structure 1 for filter material and a fiber layer 2 of the present invention.

[0020] See Figure 1 The base fabric structure 1 described in this article includes a warp and weft yarn mesh 11 and an unoriented linear structure 12. The number of the unoriented linear structures 12 is multiple and they are distributed at intervals on the base fabric structure 1. One end of the unoriented linear structure 12 is fixed on the warp and weft yarn mesh 11, and the other end diverges freely.

[0021] By this means, the base fabric structure of this embodiment, since one end of the non-directional linear structure 12 is fixed on the warp and weft yarns 11, the other end can be entangled with the fiber layer 2 when used, thereby strengthening the connection strength between the fiber layer 2 and the base fabric structure 1, so that the filter material structure formed by the composite of the base fabric structure 1 and the fiber layer 2 has a higher entanglement effect, effectively improving the mechanical properties of the filter material, making the filter material resistant to blowing good, and the fiber layer 2 and the base fabric structure 1 of the filter material not easy to peel off from each other.

[0022] In this embodiment, the warp and weft yarns of the warp and weft yarn mesh 11 are made of one of polyphenylene sulfide, polytetrafluoroethylene, aramid, and polyimide; the material of the non-directional linear structure can be one of polyphenylene sulfide, polytetrafluoroethylene, aramid, and polyimide, or a mixture of several of them, which can be consistent with the material of the warp and weft yarns of the warp and weft yarn mesh 11.

[0023] The base fabric structure of this embodiment can be produced by the following method:

[0024] First, the warp yarns 13 and weft yarns 14 are used to weave a warp and weft yarn mesh 11. Second, after the warp and weft yarn mesh 11 is produced, the non-directional linear structure 12 is fixed on the warp yarns 13, weft yarns 14 or the nodes 15 of the warp yarns 13 and weft yarns 14 of the base fabric by weaving or bonding to form the base fabric structure 1. The non-directional linear structure 12 can be a linear material such as yarn or fiber.

[0025] Alternatively, the base fabric structure 1 is formed by adding an omnidirectional linear structure 12 to the raw materials during the production process of the warp and weft yarns 11. The omnidirectional linear structure 12 can be a formed short yarn, which can be made by mixing one or more of the above-mentioned omnidirectional linear structure materials.

[0026] like Figure 2 , the lengths of the non-directional linear structures 12 of this embodiment may not be exactly the same.

[0027] The warp yarns 13 and weft yarns 14 of the warp and weft yarn mesh 11 may have diameters of 10-500 μm; the lengths of the random linear structures 12 may be 1-50 cm and the diameters may be 10-500 μm; and the random linear structures 12 may be spaced 1-10 cm apart in the warp and weft yarn mesh 11, thereby effectively improving the entanglement effect when combined with the fiber reinforcement.

[0028] like Figure 1 In this embodiment, the non-directional linear structure 12 has a curled structure. The non-directional linear structure 12 can be spirally curled as a whole, which can increase the entanglement and fixing effect between the fiber layer 2.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, equivalent changes and modifications that do not depart from the principles of the present invention should still fall within the scope of protection of the present invention.
