BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic structural diagram of the waterproof composite fabric related to the present utility model;

[0012] In the figure: 1 - moisture-conducting and antibacterial layer, 2 - waterproof layer, 3 - flame-retardant and wear-resistant layer. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Embodiment 1

[0015] Combined with Figure 1 This embodiment is described in detail. A waterproof composite fabric includes: a moisture-conducting and antibacterial layer 1, a waterproof layer 2, and a flame-retardant and wear-resistant layer 3 that are sequentially laminated; the moisture-conducting and antibacterial layer 1 is formed by interweaving a first warp yarn and a first weft yarn; the first warp yarn is formed by twisting a cotton fiber yarn and a sarcandra glabra fiber yarn; the first weft yarn is a modal fiber yarn; the flame-retardant and wear-resistant layer 3 is formed by interweaving a second warp yarn and a second weft yarn; the second warp yarn is a Dlolen yarn; the second weft yarn is formed by twisting a Pasmo high-strength polyester yarn and a nylon filament.

[0016] Sarcandra glabra has biological activities such as anti-tumor, antibacterial and anti-inflammatory, inhibiting influenza virus, promoting fracture healing, and analgesia. Substances such as astilbin in sarcandra glabra endow sarcandra glabra with a broad-spectrum antibacterial effect, and have high resistance and inhibitory effects on Escherichia coli, Staphylococcus aureus, and Candida albicans. The sarcandra glabra fiber prepared by extracting the sarcandra glabra component from natural sarcandra glabra and adding it to the spinning solution has an antibacterial function that completely comes from its plant properties and has the characteristics of being healthy and non-irritating.

[0017] The Dlolen yarn is a polyester filament yarn that combines flame retardancy and UV resistance. Since special additives are used to fix flame retardants and UV stabilizers in the fiber during the spinning process, the flame retardancy and UV resistance are permanent and machine washable. Dlolen yarn can be well dyed using pre-spinning dyeing or bath dyeing processes and is easy to process. Fabrics woven with Dlolen yarn are lighter and thinner than polyacrylonitrile fabrics of the same strength, and the fabrics do not contain heavy metals and halogens. In the event of a fire, it has a good flame retardant effect to avoid large-scale burning of the fabric, and its smoke toxicity is also low.

[0018] The Pasmo high-strength polyester yarn and the nylon filament both have good mechanical properties and good wear resistance. The flame-retardant and wear-resistant layer 3 woven from the second warp yarn and the second weft yarn can protect the inner layer fabric.

[0019] Furthermore, a water-repellent finishing agent is attached to the surface of the cotton fiber yarn. Furthermore, the moisture-conducting antibacterial layer 1 is a five-three-fly satin weave, and one side of the surface weft satin is close to the waterproof layer 2. The hygroscopicity and hygroscopicity of the first warp yarn and the first weft yarn are very different, so that the side showing the warp satin is the first warp yarn with poor hygroscopicity and good hygroscopicity, so that moisture does not remain and is quickly transferred to the side showing the weft satin. The side showing the weft satin is the first weft yarn with good hygroscopicity and hygroscopicity, which can quickly absorb the moisture transferred from the inner layer and quickly diffuse it.

[0020] Furthermore, the waterproof layer 2 is a polyurethane-based nanofiber composite fabric. The polyurethane-based nanofiber composite fabric is prepared by introducing polyvinyl butyral adhesive into a polyurethane-based spinning solution, combining electrospinning technology and hot pressing technology. The polyurethane-based nanofiber composite fabric specifically includes a base fabric layer, a TPU hot melt adhesive mesh film and a nanofiber film. The polyvinyl butyral adhesive in the fiber film melts when heated to form a large number of fusion structures, which increases the strength and elasticity between adjacent fiber fusion points. The polyurethane-based nanocomposite composite fabric has high tensile strength, large elongation at break, good water resistance and excellent moisture permeability.

[0021] Furthermore, the moisture-conducting and antibacterial layer 1, the waterproof layer 2 and the flame-retardant and wear-resistant layer 3 are compounded by a mesh hot-melt adhesive.

[0022] Embodiment 2

[0023] The difference from the first embodiment is that the waterproof layer 2 is a polytetrafluoroethylene waterproof and moisture-permeable membrane. The polytetrafluoroethylene waterproof and moisture-permeable membrane is formed by heating and melting fine powder of polytetrafluoroethylene to form a film, then performing rapid stretching, and subsequently cooling to form a reticular micro-porous structure with a thickness of about 25 μm and a porosity of 82%. The pore size is approximately one twenty-thousandth of the size of a water droplet, but 700 times larger than water vapor molecules. Based on the fact that its pore size is smaller than the size of raindrops but larger than the size of water vapor molecules, water droplets do not pass through, achieving waterproofing, while water vapor molecules can pass through, achieving moisture permeability.

[0024] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
