[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 and Figure 2 , this embodiment is described in detail. The antibacterial and antifouling coating fabric involved in this embodiment includes a composite base fabric layer 1, an antibacterial fabric layer 2 and an anti-tear fabric layer 3. The base fabric layer 1, the antibacterial fabric layer 2 and the anti-tear fabric layer 3 are composited by flame-retardant hot melt adhesive.

[0019] A PVC coating 4 is provided on the surface of the base fabric layer 1 away from the antibacterial fabric layer 2; a PVDF coating 5 is provided on the surface of the PVC coating 4 away from the base fabric layer 1; the use of the PVDF coating 5 can improve the anti-fouling ability and aging resistance of the coated fabric involved in this embodiment, and on the premise of ensuring that the coated fabric has anti-fouling properties, its service life is also improved.

[0020] Furthermore, the base fabric layer 1 is interwoven with high-strength flame-retardant polyester filaments. The antibacterial fabric layer 2 is a woven fabric interwoven with warp yarns and weft yarns, with a surface density of 100-120 g / m 2 The warp yarn used is anti-mite filament and antibacterial filament twisted together, and the weft yarn is bamboo fiber yarn; the anti-mite filament used is polyester filament containing anti-mite agent, and the fineness is 100D monofilament; the antibacterial filament used is antibacterial polyester filament, and the specification is 75D / 36F; the fineness of the bamboo fiber yarn is 20tex. The use of antibacterial filament and anti-mite filament makes the fabric have good antibacterial and anti-mite effect, and avoids the breeding of bacteria during the use of the fabric.
