Description

Technical Field

[0001] This utility model relates to the field of filter material base fabric technology, specifically to a polypropylene filament warp-knitted filter material base fabric. Background Technology

[0002] Polypropylene filament is a fiber produced from propylene through polymerization and melt spinning. Industrial production of polypropylene officially began in 1957, making it a rising star among synthetic fibers. Due to its advantages such as simple production process, low price, high strength, and relatively low density, polypropylene has developed rapidly. Currently, polypropylene is the fourth largest type of synthetic fiber and the lightest common chemical fiber. Polypropylene production includes staple fibers, filaments, and split-film fibers. Polypropylene membrane fiber is produced by first forming a thin film from polypropylene, then stretching the film to break it down into a network of fibrils. Polypropylene filament, after being made into warp-knitted filter media, is widely used in industries such as smelting, chemical plants, sugar refining, dyeing, pharmaceuticals, and food processing.

[0003] Existing polypropylene filament warp-knitted filter media base fabrics have poor support when made into filter bags, making the filter bags prone to deformation. This leads to a short service life for the filter bags, accelerates their replacement, and increases production costs. Therefore, a new type of polypropylene filament warp-knitted filter media base fabric is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a polypropylene filament warp-knitted filter material base fabric, which solves the problem that existing polypropylene filament warp-knitted filter material base fabrics have poor support when made into filter bags, making the filter bags easy to deform, which leads to short service life of the filter bags, accelerated replacement of filter bags, and increased production costs.

[0005] This utility model provides the following technical solution: a polypropylene filament warp-knitted filter material base fabric, comprising two sets of filter material base fabric layers, with a reinforcing layer provided between the two sets of filter material base fabric layers. The reinforcing layer comprises a plurality of warp threads and a plurality of weft threads, which are arranged in an alternating manner. Each warp thread and each weft thread comprises a metal wire and a nylon filament, which are spirally wound together.

[0006] Through the above scheme, after the metal wires and nylon wires are spirally wound together, several wound metal wires and nylon wires are arranged in an alternating manner. At this time, the metal wires and nylon wires can improve the support of the filter media base cloth layer, which can strengthen the filter media base cloth layer. This makes the filter media base cloth layer highly supportive when it is made into a filter bag, and it is not easy to deform after being strengthened. This improves the service life of the filter media base cloth layer after it is made into a filter bag, slows down the replacement speed of the filter bag, and thus reduces the production cost.

[0007] As a preferred embodiment of the above technical solution, each group of filter media base fabric layers is provided with an antibacterial layer at the end away from the reinforcing layer.

[0008] Through the above methods, the antibacterial layer can improve the antibacterial effect of the filter media base layer, making the filter media base layer safer and more hygienic to use after it is made into a filter bag.

[0009] As a preferred embodiment of the above technical solution, each group of antibacterial layers has a flame-retardant layer at the end away from each group of filter material base fabric layers.

[0010] The above solution can increase the flame retardancy of the filter bag after the filter material base layer is made into a filter bag, making the filter bag safer and more environmentally friendly to use.

[0011] As a preferred embodiment of the above technical solution, each group of flame-retardant layers is provided with a waterproof component at the end away from each group of antibacterial layers.

[0012] The above solution enhances the waterproofness of the filter bag after the filter media base layer is made.

[0013] As a preferred embodiment of the above technical solution, each set of waterproof components has a wear-resistant layer at the end away from each set of flame-retardant layers.

[0014] By using the above method, the wear-resistant layer increases the wear resistance of the filter bag after it is made into a filter bag, which can improve the service life of the filter bag.

[0015] As a preferred embodiment of the above technical solution, the waterproof component includes a waterproof fabric layer, the top of which is provided with a waterproof coating first, and the bottom of which is provided with a waterproof coating second.

[0016] The above solution can increase the water resistance of the filter bag after the filter material base layer is made into a filter bag, so that the filter bag dries faster after coming into contact with water, making the filter bag easier to use.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a spiral winding of metal wires and nylon filaments, with several interlaced metal and nylon filaments arranged to enhance the support of the filter media base fabric layer. This reinforces the filter media base fabric layer, resulting in high support when the filter media base fabric layer is made into a filter bag. After reinforcement, it is less prone to deformation, thereby increasing the service life of the filter media base fabric layer after it is made into a filter bag, slowing down the replacement rate of the filter bags, and thus reducing production costs.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a polypropylene filament warp-knitted filter material base fabric, comprising two sets of filter material base fabric layers 2, with a reinforcing layer 1 disposed between the two sets of filter material base fabric layers 2. The reinforcing layer 1 includes a plurality of warp threads 101 and a plurality of weft threads 102, which are arranged alternately. Each warp thread 101 and each weft thread 102 includes a metal wire 103 and a nylon filament 104, which are spirally wound together. After the metal wire 103 and nylon wire 104 are spirally wound together, the several wound metal wires 103 and nylon wires 104 are arranged in an alternating manner. At this time, the metal wires 103 and nylon wires 104 can improve the support of the filter material base cloth layer 2 and strengthen the filter material base cloth layer 2. This makes the filter material base cloth layer 2 have high support when it is made into a filter bag, and it is not easy to deform after being strengthened. This improves the service life of the filter material base cloth layer 2 after it is made into a filter bag, slows down the replacement speed of the filter bag, and thus reduces the production cost.

[0026] As one implementation method in this embodiment, such as Figure 1As shown, each set of filter media base fabric layer 2 has an antibacterial layer 3 at the end away from the reinforcing layer 1. The antibacterial layer 3 can be made of ZIF-chitosan-fabric composite material. The antibacterial layer 3 can improve the antibacterial effect of the filter media base fabric layer 2, making the filter bags made from the filter media base fabric layer 2 safer and more hygienic to use. Each set of antibacterial layer 3 has a flame-retardant layer 4 at the end away from each set of filter media base fabric layer 2. The flame-retardant layer 4 can be an inherently flame-retardant fabric, such as aramid, acrylic cotton, DuPont Kevlar, Nomex, Australian PR97, etc. The flame-retardant layer 4 can increase the flame retardancy of the filter bags made from the filter media base fabric layer 2, making the filter bags safer and more environmentally friendly to use. Each set of flame-retardant layer 4 has a waterproof component 5 at the end away from each set of antibacterial layer 3. One end of the flame-retardant layer 4 is provided with a wear-resistant layer 6. The wear-resistant layer 6 can be made of Cordura nylon fabric, which is a functional fabric that is lightweight, quick-drying, soft, and durable. It increases the wear resistance of the filter bag after the filter base fabric layer 2 is made into a filter bag, thereby improving the service life of the filter bag. The waterproof component 5 includes a waterproof fabric layer 501. The top of the waterproof fabric layer 501 is provided with a waterproof coating 502, and the bottom of the waterproof fabric layer 501 is provided with a waterproof coating 503. The waterproof fabric layer 501 is made of a composite of a high-polymer waterproof and breathable material PTFE membrane and fabric. The top and bottom ends are coated with waterproof coating 502 and waterproof coating 503 respectively, which can increase the waterproofness of the filter bag after the filter base fabric layer 2 is made into a filter bag, so that the filter bag dries faster after contact with water, making the filter bag easier to use.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
