[0020] The utility model embodiment provides a high interception rate nylon filter material, such as Figure 1-3 As shown, it includes radial monofilaments 11, axial monofilaments 12, a first filter ring 13, a second filter ring 14, a filter membrane 15, and a limiting ring 16.

[0021] like Figure 1-3 As shown, it includes a first nylon mesh, a second nylon mesh and a support layer, the support layer is fixedly connected to the second nylon mesh, the first nylon mesh and the second nylon mesh are compounded by pressing, the first nylon mesh includes radial monofilaments 11 and axial monofilaments 12, the radial monofilaments 11 and the axial monofilaments 12 are woven perpendicularly to each other, the second nylon mesh includes a first filter ring 13 and a second filter ring 14, the first filter ring 13 and the second filter ring 14 are interlocked in the same row.

[0022] It is worth noting that the distance between the first filter rings 13 in different rows is smaller than the radius of the first filter ring 13, the gap between the radial monofilaments 11 and the axial monofilaments 12 is larger than the gap in the second filter ring 14, and the first filter ring 13 and the second filter ring 14 are shaped by hot-melt single-sided calendering.

[0023] The radial monofilaments 11 and the axial monofilaments 12 are modified by the sol-gel method using nano-carbon sol. The radial monofilaments 11 and the axial monofilaments 12 are PA6 / PE island-type composite ultrafine fibers impregnated with xylene. The PA6 / PE island-type composite ultrafine fibers are blended and spun by two incompatible polymer components, polyamide 6 (PA6) and polyethylene (PE), to form a matrix-microfiber fiber with PA6 as the "island" phase and PE as the "sea" phase. In the production process of this fiber, it is necessary to remove the "sea" phase PE through specific technical means to obtain PA6 ultrafine fibers.

[0024] The support layer includes a filter membrane 15 and a limiting ring 16. The limiting ring 16 is fixedly connected to a side of the filter membrane 15 close to the first filter ring 13. The limiting ring 16 is interlocked with the second filter ring 14. The filter membrane 15 is made of a composite sterilization membrane, and the filter membrane 15 is composited in a twill weave.

[0025] When the filter material of this scheme is filtered, larger particles remain on the side of the first nylon mesh away from the second nylon mesh, smaller gel particles are retained in the first filter ring 13 and the second filter ring 14, and the liquid flows out from the limit ring 16, thereby ensuring the filter material retention efficiency of this scheme.

[0026] And this scheme can prevent clogging by flushing clean water toward the filter membrane 15.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
