Description

Technology field

The present invention relates to a method for cutting a fabric having a mountain-shaped convex portion and a valley-shaped concave portion that can be made seamlessly by a method of creating a three-dimensional shape with a stretchable spring with a bias left and a bias right spring.

Conventionally, as disclosed in, for example, U.S. Pat. No. 6,800,199B2 and Japanese Patent Application No. 2000-400120, the left-right cutting bias portion is formed by using a fabric cloth woven at 90 degrees in length and breadth as a 45-55 degree square fabric. And the right-left cutting bias part was distinguished and stretched in one direction ... Cut flat fabric.

Problems to be solved by the invention

Cutting fabric with a bias uses a lot of fabric because it requires two pieces of fabric from a square fabric by left-cutting and right-cutting. Unnecessary parts are empty spaces in FIGS. 1 (a) to (h) R8 to L8. This is because the blank part can be used effectively by utilizing the dart part by utilizing the dart part. Fig. 3 (b) Spade-shaped blank part Z on the front of the long pants is inverted from the left to the right. The blank Z is also a fabric cloth. Knit knitted fabric also has a square reversal bias. By using left (right) bias for left (right) of Fig. 2 (a) Right (L7) for the diagonal line of square fabric and left (right) for Fig. 2 (a) Right (L7), it is a glance. Reverse the waste of cutting cloth with a bias that is easy to understand.

Means for solving the problem

The inventor of the present invention is a square fabric woven at 90 degrees in length and breadth, and the bias slanted portion cannot be removed from one piece to the left to right cloth. As a result, the three-dimensional shape, mountain shape, or valley shape of the fabric could not be made. The normal fabric and the tension fabric had their own bias repulsion with the left bias and the right bias, and they overlap on one fabric, so one side bias However, the present inventor invented a new injection when he noticed that it was impossible to cut one piece at the overlapped part of the small crotch at the center line of the forehead. In other words, the overlapping part is the idea of reversing the required fabric amount, the deficit of the overlapping part is darted in the opposite way, and the lower crotch part centered on the front body is experimentally prototyped over and over again. Knit fabrics, fabric fabrics, or long fabrics (longPants) pants that have been completed. Shorter briefs have been completed on KnitWhee maps 4 (a)-(c). Furthermore, the fabric fabric brief is a fabric brief that can be stretched by cross-cutting the front right bias and the rear left bias. FIG. 6 (f) is a completed drawing. FIGS. 2 to 3 are also practical drawings in which the paper pattern is reduced. Patent technology is disclosed in U.S. Pat. S. Brief of stretchable fabric body generated at the intersection of the square left biased fabric and the next square (opposite side) right bias disclosed in Japanese Patent No. 6800159B2 and Japanese Patent Application No. 2000-400120, as shown in FIG. 6 (f). One sheet of fabric biased briefs and one sheet of right bias checked and another sheet of left biased fabric (photo).
