Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabrics, in particular to a warp-knitted and weft-knitted fabric with high waterproof performance. Background Technique

[0002] A knitted fabric is a fabric formed by bending yarns into loops and interlacing them with knitting needles. The difference between a knitted fabric and a woven fabric lies in the different forms of the yarns in the fabric. Knitting is divided into weft knitting and warp knitting. In fact, warp knitting and weft knitting are the traditional weaves. The method is to stretch the warp threads first, then pass the weft threads, put the threads on the needles, and pass the threads up and down on the warp threads. After passing through several loops, the threads are pressed tightly until the warp threads are invisible.

[0003] The knitted fabric formed by warp knitting and weft knitting is widely used in various types of clothing. Generally, the existing knitted fabrics do not have high waterproof ability, and it is easy for rainwater to penetrate to the skin on rainy days, thus affecting the application range of the fabric. Therefore, a warp-knitted and weft-knitted fabric with high waterproof performance is proposed to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a warp-knitted and weft-knitted fabric with high waterproof performance, which has the advantages of high-strength waterproof effect, etc., and solves the problem that the knitted fabric formed by warp knitting and weft knitting is widely used in various types of clothing, and the existing knitted fabrics generally do not have high waterproof ability, and it is easy for rainwater to penetrate to the skin on rainy days, thus affecting the application range of the fabric.

[0006] The functional structure includes an anti-roll layer, a first waterproof layer, a second waterproof layer, an anti-static layer, an antibacterial layer, antibacterial particles and a breathable layer. The anti-roll layer is arranged inside the knitted fabric body, the first waterproof layer is arranged inside the knitted fabric body, the second waterproof layer is arranged inside the knitted fabric body, the anti-static layer is arranged inside the knitted fabric body, the antibacterial layer is arranged inside the knitted fabric body, the antibacterial particles are arranged inside the antibacterial layer, and the breathable layer is arranged inside the knitted fabric body.

[0007] Further, the polyamide fiber and the nylon fabric are cross-connected with each other, and the antibacterial layer is attached to the top of the polyamide fiber and the nylon fabric.

[0008] Further, an antistatic layer is attached to the top of the antibacterial layer, and a second waterproof layer is attached to the top of the antistatic layer.

[0009] Further, a first waterproof layer is attached to the top of the second waterproof layer, and a curling prevention layer is attached to the top of the first waterproof layer.

[0010] Further, a breathable layer is attached to the bottom of the cotton fiber and nylon fabric.

[0011] Further, the cotton fiber is made of cotton thread, and the nylon fabric is made of polyamide fiber.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] For this high-waterproof warp-knitted and weft-knitted fabric, the antibacterial layer is mainly made of bamboo charcoal fiber, and the antibacterial particles are silver ion particles.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , a warp-knitted and weft-knitted fabric with high waterproofness in this embodiment includes a knitted fabric body 1. There is a cotton fiber 2 inside the knitted fabric body 1, a nylon fabric 3 inside the knitted fabric body 1, and a functional structure 4 inside the knitted fabric body 1.

[0021] The functional structure 4 includes an anti-rolling layer 401, a first waterproof layer 402, a second waterproof layer 403, an anti-static layer 404, an antibacterial layer 405, antibacterial particles 406, and a breathable layer 407. There is an anti-rolling layer 401 inside the knitted fabric body 1, a first waterproof layer 402 inside the knitted fabric body 1, a second waterproof layer 403 inside the knitted fabric body 1, an anti-static layer 404 inside the knitted fabric body 1, an antibacterial layer 405 inside the knitted fabric body 1, antibacterial particles 406 inside the antibacterial layer 405, and a breathable layer 407 inside the knitted fabric body 1.

[0022] In Figure 2 , the cotton fiber 2 is made of cotton thread. There are ventilation holes left between the cotton threads. The cotton threads themselves have strong air permeability, and coupled with the setting of the ventilation holes, the air permeability of the fabric is improved.

[0023] In Figure 2 , the nylon fabric 3 is polyamide fiber. Among them, amide has good stability to mineral oil, animal oil, and vegetable oil, and is relatively wear-resistant during the wearing process. Polyamide products are odorless, tasteless, non-toxic, and will not rot.

[0024] In Figure 3 , by laminating the first waterproof layer 402 and the second waterproof layer 403 and locating them on the top of the cotton fiber 2 and the nylon fabric 3, and the breathable layer 407 is located at the bottom of the cotton fiber 2 and the nylon fabric 3, the waterproofness of the knitted fabric can be well enhanced.

[0025] In summary, for the warp-knitted and weft-knitted fabric with high waterproof performance, the material of the antibacterial layer 405 is mainly made of bamboo charcoal fiber, and the antibacterial particles 406 are silver ion particles. Through the mutual cooperation between the antibacterial layer 405 and the antibacterial particles 406, it can effectively prevent bacteria from growing on the knitted fabric body 1, and has a good antibacterial effect, solving the problem of poor antibacterial ability. The material of the antistatic layer 404 is polyaniline conductive fiber filaments, and the diameter of the polyaniline conductive fiber filaments is 6um. The polyaniline conductive fiber can play a conductive role, so as to play an antistatic role for the knitted fabric body 1. The material of the second waterproof layer 403 is polymer modified asphalt. The fabric made of polymer modified asphalt has the advantages of good waterproof performance and environmental protection. The material of the first waterproof layer 402 is waterborne polyurethane. Waterborne polyurethane has a strong affinity with water, and at the same time has excellent properties such as low temperature resistance, good flexibility and high bonding strength. The anti-rolling layer 401 is made of high-elastic silicone GR-73E. The anti-rolling layer 401 can solve the problem that the edge of the knitted fabric body 1 curls under humid and hot environments. The material of the breathable layer 407 is a breathable nano-thin layer. In order to make the fabric have better waterproof performance and more breathability, the breathable layer 407 is placed at the bottom of the cotton fiber 2 and the nylon fabric 3, solving the problem that the knitted fabric formed by warp knitting and weft knitting is widely used in various types of clothing. Existing knitted fabrics generally do not have high waterproof ability, and it is easy for rainwater to penetrate to the skin on rainy days, thus affecting the use range of the fabric.
