Obviously, the described embodiments are some embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0020] It should be noted that similar reference numerals and letters refer to like items in the accompanying drawings, and once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0021] The electrical components described herein are all electrically connected to a main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer.

[0022] In the description of the embodiments of the present application, it should be noted that the positions or position relationships indicated by the terms "inner", "outer", "upper", etc.

[0023] With reference to Figs. 1-2 The waterproof and light-shielding composite fabric comprises a base cloth layer 1, the surface of the base cloth layer 1 is provided with a waterproof and breathable layer 2, the surface of the waterproof and breathable layer 2 is provided with a light-shielding layer 3, the light-shielding layer 3 comprises a black non-woven fabric 31 and an aluminum foil layer 32, and the aluminum foil layer 32 is arranged on the outer layer of the black non-woven fabric 31, the black non-woven fabric 31 can efficiently absorb and block most light, and mainly undertakes the light-shielding function, the aluminum foil has good light reflection performance and can reflect the light not absorbed by the black non-woven fabric 31, thereby further enhancing the light-shielding effect of the fabric.

[0024] Further, the base cloth layer 1 is made of polyester fiber with high strength and high wear resistance as the base fabric, which can provide a solid foundation support for the entire composite fabric and ensure that the fabric maintains good physical properties and is not easily damaged in daily use and various complex environments.

[0025] Further, the waterproof and breathable layer 2 is an organic silicon waterproof agent, which is coated on the surface of the base cloth layer 1 by using a doctor blade coater, and the coating thickness can be accurately controlled by using the doctor blade coating method.

[0026] Further, the aluminum foil layer 32 is tightly connected with the black non-woven fabric 31 by hot pressing and is firmly attached to the waterproof coating layer, thereby forming a stable and reliable composite structure.

[0027] Furthermore, the surface of the aluminum foil layer 32 is coated with a polyurethane coating. As a wear-resistant material, the polyurethane coating is prepared by dissolving polyurethane resin in an organic solvent through a solution coating method, forming a coating liquid with a suitable viscosity, and uniformly coating it onto the surface of the aluminum foil layer 32 using precision coating equipment. After drying and curing in an oven, the polyurethane coating has good flexibility and wear resistance, effectively resisting damage caused by friction and scratches during daily use, protecting the metallized layer from damage, and maintaining its high reflectivity and light-shielding performance.

[0028] Furthermore, the polyester fibers of the base fabric layer 1 are arranged in a crisscross pattern, with the warp and weft fibers tightly interwoven to form a stable basic structure, giving the base fabric good mechanical properties. The warp fibers provide longitudinal tensile strength, while the weft fibers enhance transverse toughness. The interwoven structure allows the base fabric layer 1 to have a certain tensile strength in all directions, making it less prone to deformation or tearing when resisting external forces.

[0029] In summary, through its uniquely designed waterproof coating, the fabric effectively resists rainwater penetration and can be widely used in outdoor awnings, tents, and other scenarios with extremely high waterproof performance requirements, providing users with a dry and comfortable environment. The synergistic effect of the black non-woven fabric 31 and the aluminum foil layer 32 in the light-blocking layer 3 greatly enhances the fabric's light-blocking performance, meeting the needs of places with extremely strict light control, such as photography studios and cinemas, ensuring that the ambient light meets specific requirements. The use of high-strength base fabric layer 1 gives the composite fabric high overall strength and durability, extending the fabric's service life, reducing usage costs, and improving the product's cost-effectiveness. The waterproof and breathable layer 2 formed by the silicone waterproofing agent and the polyester fiber base fabric layer 1 are precisely controlled through a scraping method to ensure that the waterproofing agent firmly adheres to the surface of the base fabric layer 1, forming a stable waterproof and breathable membrane without damaging the structure and performance of the base fabric layer 1.
