Abstract: Provided is a cutting processing method for a seam allowance of an overcoat. The method comprises the following steps: (1) cutting: flattening fabric in a yarn direction and then cutting same according to a structural board, and adjusting the magnitude of a slope; (2) drawing, and sticking a panel strip: laying the structural board on a front piece of the fabric, drawing a net line according to the structural board, and sticking, to the net line, a 6-degree bias or a 12-degree bias panel strip for fixation; (3) sewing: lifting the front piece and a facing to check that the shapes and sizes of the two pieces are complementary, and then sewing a seam allowance according to the position of the net line on the front piece; and (4) ironing. The method makes a breakthrough in the current conventional practices in terms of pattern-making. A seam allowance slopes according to the texture of the fabric, such that after being sewed together with the facing, the seam allowance can match the fabric slackness of a cut piece, wherein the slope is 0.5-2.5 degrees. During sewing, the 6-degree bias or the 12-degree bias panel strip is stuck for fixation, such that the seam allowance is slack after being sewed, and the completed seam allowance is both straight and beautiful. At the same time, a new employee can also complete a sewing operation, thereby greatly improving the production efficiency and reducing the problem of a low sewing rate.
