The invention discloses a yoga pants plane pattern making method based on sports
engineering and yoga pants, and belongs to the technical field of clothing pattern making. The yoga pants plane pattern making method comprises the steps that a
waistline, a hip line, a crosspiece line, a knee line, a shank line and a foot opening line are sequentially determined on a material, and the height position of each circumference line is obtained according to the parallel offset relation of the
waistline in the first direction; determining a front center line, a rear center line and a
waist dart line according to the hip line, the crosspiece line and the knee line, and determining specific sizes of the knee line, the shank line and the foot opening line according to the shank line and the foot opening line;
cutting the material into a basic prototype according to the line segments and the positioning points, and setting a belly parting line, a
waist dart and a pocket opening on the basic prototype, so as to obtain a
cut-part picture for manufacturing; and the plane model can be matched with the dynamic change of a
human body in the knee bending, stretching and twisting processes, so that the fitness and the
extensibility of the manufactured yoga trousers are improved.
