1. A method of collectively preparing moisture-permeable waterproof clothing, the method comprising:
a step of cutting a fabric substrate and a moisture-permeable waterproof film into a plurality of pieces according to an apparel design, wherein the plurality of pieces are at least divided into a first piece group and a second piece group, wherein the first piece group comprises a first fabric substrate and a first moisture-permeable waterproof film, and the second piece group comprises a second fabric substrate and a second moisture-permeable waterproof film;
a step of forming a first laminate by processing the first piece group, wherein the step of forming the first laminate comprises a step of attaching a film-type adhesive having a predetermined width to one end of a first surface of the first moisture-permeable waterproof film, a step of laminating a release paper having a predetermined width on one end of a first surface of the first fabric substrate, a step of laminating the first moisture-permeable waterproof film on the first fabric substrate such that the first surface of the first moisture-permeable waterproof film and the first surface of the first fabric substrate face each other, a step of partially and temporarily adhering the first moisture-permeable waterproof film and the first fabric substrate to each other by partial heat-pressing without an adhesive, and a step of removing the release paper to form a first laminate, wherein the release paper prevents the first fabric substrate and the first moisture-permeable waterproof film from temporarily adhering by at least a width of the release paper in the step;
a step of forming a second laminate by processing the second piece group, wherein the step of forming the second laminate comprises a step of laminating the second moisture-permeable waterproof film on the second fabric substrate such that a first surface of the second moisture-permeable waterproof film and a first surface of the second fabric substrate face each other and a step of temporarily adhering the second moisture-permeable waterproof film and the second fabric substrate to each other by heat-pressing without an adhesive to form a second laminate;
a step of forming a seam by arranging the first laminate and the second laminate such that the first fabric substrate of the first laminate and the second fabric substrate of the second laminate face each other and then connecting the first fabric substrate and the second fabric substrate;
a step of covering an area of the seam with the second moisture-permeable waterproof film of the second laminate and then covering the second moisture-permeable waterproof film with the first moisture-permeable waterproof film of the first laminate; and
a step of finally laminating the first laminate and the second laminate along with the seam,
wherein (1) the step of forming a second laminate further comprises a step of laminating a release paper having a predetermined width on one end of the first surface of the second fabric substrate before the step of laminating the second moisture-permeable waterproof film on the second fabric substrate, and (2) the step of temporarily adhering the second moisture-permeable waterproof film and the second fabric substrate to each other is a step of forming the second laminate by temporarily adhering the second moisture-permeable waterproof film and the second fabric substrate to each other by heat-pressing and then removing the release paper, and
wherein in the step of forming the second laminate, unlike in the step of forming the first laminate, the film-type adhesive is not attached onto the second moisture-permeable waterproof film.
