1284162 V. Description of invention (2) Antifungal and antibacterial effect. However, if the fabric is treated in a non-complex manner, the fabric is generally soft and the fabrics are not easily rubbed by each other, but the moisture-permeable polyurethane (PU) film which is blown out cannot overcome the problem of dry surface. Because the cause of cognac is mainly that the film itself is pure and has excellent waterproof and moisture permeability, the tactile sensation is also poor due to the characteristics of the pure substance. Moreover, generally, the directly blown formed film is processed and adhered to the fabric, and the fabric has excellent performance in waterproof and moisture permeability, but there is no significant antibacterial and antibacterial effect and the surface touch is dry and criticized. At present, most of the methods used are to coat the film to adhere a layer of thin cloth after the layer, which is a way to improve the touch, but the economic benefit is not good, and there is almost no anti-mildew and antibacterial effect. In view of the above, the present invention has been made in view of the above problems, and proposes a polyurethane multilayer film fabric having antibacterial and mildew resistance and a method for producing the same, so as to improve the problem of the conventional disease. SUMMARY OF THE INVENTION The main object of the present invention is to provide a polyurethane multilayer film fabric having antibacterial and mildew resistance and a method for producing the same, and the obtained multilayer film fabric has excellent performance in waterproof and moisture permeability, and The performance on touch and antibacterial and mildew resistance is also outstanding. Another object of the present invention is to provide a polyurethane multilayer film fabric having antibacterial and antifungal properties and a method for producing the same, which is a polyurethane (PU) multilayer film which is environmentally friendly, pollution-free, and not harmful to human health and soft and elastic. Fabric, and it also has the characteristics of light weight and antibacterial and mildew resistance.

1284162 V. INSTRUCTIONS (3) A high level of exercise and a need to protect the body and fabrics. A further object of the present invention is to provide a polyurethane multilayer film fabric having antibacterial and mildew resistance and a method for producing the same, which comprises adding an antibacterial and antifungal agent to a composite layer instead of merely performing a cloth surface treatment, so the antibacterial and antifungal agent Almost unaffected by water washing. In order to achieve the above object, the polyurethane multilayer film fabric disclosed in the present invention and the manufacturing method thereof are firstly used to adhere a moisture permeable polyurethane film to a surface of a fabric fabric by using an adhesive layer; and then a surface modifying agent is included. A resin film of a mold-proof antibacterial agent is coated on the surface of the polyurethane film to form a high-performance polyurethane multilayer film fabric with the resin film and the polyurethane film and the fabric.
