1. A method for making an air permeable and waterproof textile with an uneven pattern, the steps comprising:
a needle threading step: transporting a fabric foundation through a row needle set with a transportation speed toward a transporting direction, a plurality of threading holes are formed after the fabric foundation is threaded by the row needle set, the row needle set is arranged above the fabric foundation and spaced apart therefrom a distance, the fabric foundation at least includes a cloth carrier and a waterproof film made by soft plastic materials and melt adhered on a surface of the cloth carrier, the cloth carrier is arranged adjacent to the row needle set and the waterproof film is arranged opposite to the row needle set, a burr portion is extended from the waterproof film downwardly corresponding to each threading hole, and a semi-finished product is formed; a roll-over step: transporting the semi-finished product in the transporting direction and passing between an upper roller and a lower roller arranged below the upper roller to be rolled over, and a predetermined pattern is concavely formed on a surface of the lower roller, the lower roller is heated to deform the waterproof film so that the threading holes are totally or partially shielded by corresponding burr portions with different extent and then formed water proof and air permeability with different degree, and an uneven pattern is formed on the fabric foundation corresponding to the predetermined pattern; and a forming step: cooling the semi-finished product after the roll-over step to form an air permeable waterproof textile with the uneven pattern. |
