Description

Technical Field

[0001] This utility model relates to the field of polyester fiber filter cloth technology, specifically a double-sided irregular polyester fiber filter cloth structure. Background Technology

[0002] Polyester fiber is the most widely used and highest-volume material among polyester fibers. Its common cross-section is circular, but it can also be shaped into irregularly shaped fibers. Polyester fiber filter cloth is a filter material made primarily from polyester fiber through a special process. Based on filtration precision, it can be divided into coarse filter cloth, medium filter cloth, and fine filter cloth.

[0003] After ordinary polyester fiber filter cloth is used to filter media, it is easily deformed or damaged by impact. To address this, we propose a double-sided irregular polyester fiber filter cloth structure. Summary of the Invention

[0004] The purpose of this invention is to provide a double-sided irregularly shaped polyester fiber filter cloth structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-sided profiled polyester fiber filter cloth structure includes:

[0007] The base fiber layer and the profiled polyester fiber layer woven on both sides of the base fiber layer, wherein the mesh size of the base fiber layer is larger than the mesh size of the profiled polyester fiber layer.

[0008] Preferably, the base fiber layer is woven from several crisscrossing polyester warp and weft threads.

[0009] Preferably, the profiled polyester fiber layer is formed by weaving together several crisscrossing profiled polyester fiber warp and weft threads.

[0010] Preferably, the shaped polyester fiber is one or more of the following: triangular shaped fiber, Y-shaped shaped fiber, pentagonal shaped fiber, trilobal shaped fiber, tetralobal shaped fiber, pentlobal shaped fiber, fan-shaped shaped fiber, and hollow shaped fiber.

[0011] Preferably, the surfaces of the base fiber layer and the profiled polyester fiber layer are coated with a silver ion coating layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The basic fiber layer of this invention provides support for the profiled polyester fiber layers on both sides, maintains the shape of the profiled polyester fiber layers, provides filtration for the flowing medium through the profiled polyester fiber layers, and works with the basic fiber layer to prevent clogging of the medium.

[0014] The basic fiber layer of this invention uses high-strength polyester fiber to provide stable support and enhance the overall mechanical strength of the filter cloth, enabling it to withstand the pressure and tension generated during filtration and preventing problems such as cracking and deformation of the filter cloth during use. The fiber structure of the support layer is relatively loose, forming a good flow channel, which helps the filtered liquid or gas to be discharged quickly and improves the filtration efficiency.

[0015] The silver ion coating layer of this invention is used to inhibit bacteria from adsorbing onto the surface of the base fiber layer and the profiled polyester fiber layer, prevent bacteria from damaging the internal structure of the surface of the base fiber layer and the profiled polyester fiber layer, and provide disinfection treatment for the medium flowing through it.

[0018] In the diagram: 1. Basic fiber layer; 2. Shaped polyester fiber layer. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 A double-sided profiled polyester fiber filter cloth structure, comprising:

[0021] The base fiber layer 1 and the profiled polyester fiber layer 2 woven on both sides of the base fiber layer 1, wherein the mesh size of the base fiber layer 1 is larger than the mesh size of the profiled polyester fiber layer 2.

[0022] Using the above technical solution, the base fiber layer 1 is used to provide support for the profiled polyester fiber layers 2 on both sides, maintain the shape of the profiled polyester fiber layers 2, provide filtration treatment for the flowing medium through the profiled polyester fiber layers 2, and cooperate with the base fiber layer 1 to avoid clogging the medium.

[0023] like Figure 2 As shown, the basic fiber layer 1 is woven from several interlaced polyester warp and weft threads.

[0024] Using the above technical solution, the base fiber layer 1 is made of high-strength polyester fiber to provide stable support and enhance the overall mechanical strength of the filter cloth, enabling it to withstand the pressure and tension generated during the filtration process and preventing problems such as cracking and deformation of the filter cloth during use. At the same time, the fiber structure of the support layer is relatively loose, forming a good flow channel, which helps the filtered liquid or gas to be discharged quickly and improves the filtration efficiency.

[0025] The profiled polyester fiber layer 2 is woven from several crisscrossing profiled polyester fiber warp and weft threads. The profiled polyester fibers are one or more of the following: triangular profiled fibers, Y-shaped profiled fibers, pentagonal profiled fibers, trilobal profiled fibers, tetralobal profiled fibers, pentlobal profiled fibers, fan-shaped profiled fibers, and hollow profiled fibers.

[0026] Using the above technical solution, the irregularly shaped fibers have a strong light reflection effect, making the dirt particles appear smaller and giving them a sense of anti-fouling performance. Furthermore, due to the strong cohesion, small filaments are not easily exposed, greatly reducing pilling. The tightly arranged fibers of the filter layer can effectively trap various impurity particles in liquids or gases, providing a high-precision filtration effect and ensuring that the filtered medium reaches a high level of purity.

[0027] The surfaces of the base fiber layer 1 and the profiled polyester fiber layer 2 are coated with a silver ion coating layer.

[0028] Using the above technical solution, the silver ion coating layer is used to inhibit bacteria from adsorbing on the surface of the base fiber layer 1 and the profiled polyester fiber layer 2, prevent bacteria from damaging the internal structure of the surface of the base fiber layer 1 and the profiled polyester fiber layer 2, and provide disinfection treatment for the flowing medium.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
