Abstract:

In order to improve the functionality and comfort of yoga pants, the structure design methods for weft-knitted seamless yoga pants were studied. This paper analyzed the characteristics of the circumference of the human lower limbs and the deformation of the mussle during yoga exercises, and the changes in the skin of the lower limbs were mapped in the form of a grid diagram. Seven types of fabrics with different structures were knitted with spandex and nylon, and the tensile properties and pressure values of the fabrics were measured. The partition structure design of the weft-knitted seamless yoga pants was carried out from the girth size and the longitudinal structure, and application examples were given. The results show that the difference in garment girth size is achieved by adjusting the ratio of the number of knitting needles of different fabrics, and the amount of garment shrinkage can be adjusted by the pressure value of the transverse stretch of the fabric. In the longitudinal design of the garment, the tensile properties of the fabric is proportional to the value of skin deformation. The structural design of seamless yoga pants needs to consider the characteristics of lower limb movement, fabric performance and seamless forming principles. This technology can be applied to other types of sports apparel design, which helps to improve the scientific and production efficiency of apparel structure design.
