[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, a nylon sunscreen fabric comprises: a surface layer 1, a waterproof layer 2 and an inner layer 3. The number of the waterproof layer 2 is two layers, which are respectively arranged on both sides of the inner layer 3. The number of the surface layer 1 is two layers, which are arranged on the side of the waterproof layer 2 away from the inner layer 3.

[0021] The surface layer 1 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and weft yarns include nylon filaments 11 and fluorescent polyester filaments 12. Figure 2As shown, the nylon filaments 11 and the fluorescent polyester filaments 12 are arranged in a 1:1 ratio in the warp and weft yarns, and the fineness of the nylon filaments 11 is greater than that of the fluorescent polyester filaments 12, that is, the nylon filaments 11 are thicker than the fluorescent polyester filaments 12, so that the top of the nylon filaments 11 is higher than the top of the fluorescent polyester filaments 12. When in use, the nylon filaments 11 contact the object, and the fluorescent polyester filaments 12 do not contact the object, which has a protective effect on the fluorescent polyester filaments 12 and can prevent the fluorescent layer on the surface of the fluorescent polyester filaments 12 from being worn.

[0022] Among them, the density of the warp yarn of the surface layer 1 is 30-50 yarns / cm, and the density of the weft yarn is 35-55 yarns / cm, which makes the surface layer 1 dense and has a certain waterproof ability. It can be combined with the waterproof layer 2 to make the fabric have excellent waterproof performance. At the same time, the dense surface layer 1 can also block sunlight from passing through the fabric to the greatest extent.

[0023] Preferably, the nylon filaments 11 used in the warp and weft yarns of the surface layer 1 are flame-retardant nylon filaments. The fluorescent polyester filaments 12 include flame-retardant polyester filaments and a fluorescent coating coated on the outer surface of the flame-retardant polyester filaments. The flame-retardant nylon filaments and the flame-retardant polyester filaments give the fabric a certain flame-retardant property, and the protective property is better after being made into a tarpaulin.

[0024] Furthermore, the surface of the nylon filaments 11 used in the warp and weft yarns of the surface layer 1 is provided with a glass bead reflective coating, so that the surface layer 1 has a reflective effect, which can reflect part of the sunlight and reduce the impact of light on the fabric.

[0025] A transparent polyurethane coating 4 is coated on the side of the surface layer 1 away from the waterproof layer 2 to improve the overall wear resistance, waterproofness and durability of the fabric. At the same time, the polyurethane coating 4 can also protect the glass bead reflective coating and the fluorescent coating from wear.

[0026] The waterproof layer 2 is a waterproof and breathable film layer, and the waterproof and breathable film layer is a PTFE film, which makes the fabric have excellent waterproof performance. The waterproof layer 2 is arranged on the inner side of the surface layer 1, and is protected by the surface layer 1, and is not easily damaged by wear and tear, so that the waterproof effect of the fabric is longer. The function of the waterproof layer 2 is to prevent water and other liquids from penetrating the fabric and wetting the items covered by the tarpaulin made of the fabric.

[0027] The inner layer 3 is formed by interweaving warp yarns and weft yarns. Both the warp yarns and the weft yarns are electromagnetic shielding composite yarns. Figure 3As shown, the electromagnetic shielding composite yarn includes a core wire and a wrapping wire, wherein the core wire is a stainless steel fiber yarn 13; the wrapping wire is spirally wound around the outside of the core wire and is a nylon filament 11. The electromagnetic shielding effect of the stainless steel fiber yarn 13 mainly comes from the conductive properties of the metal components inside it. Under the action of electromagnetic waves, the electric dipoles in the stainless steel fiber are affected by the electromagnetic field to generate eddy currents, which in turn generate an anti-magnetic field to offset the original magnetic field, generate heat loss, consume electromagnetic energy, and thus play a role in weakening electromagnetic radiation. In addition, multiple reflections of electromagnetic waves inside the stainless steel fiber will also cause energy loss of the electromagnetic waves, further enhancing its electromagnetic shielding effect. The nylon filament 11 is used to protect the stainless steel fiber yarn 13.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
