The study analyzed the skin deformation of women’s limbs under yoga, and established a digital design model of weft-knitted seamless yoga pants based on skin deformation. Five representative yoga moves were selected. Eight female participants were selected to perform a standard standing posture and yoga postures. Three-dimensional scanning technology was used to measure the participants’ lower limbs, and skin data on different parts of the lower limbs were analyzed. The prototype of seamless pant was partitioned based on the skin deformation data, and it was establish a partition design model of weft knitted seamless yoga pant. By creating an fabric structure library and classifying it according to the tensile properties of the fabric structure, establishing the correspondence between the model partition and the fabric structure classification, which realized the digital design of the seamless yoga pants structure. The research results can provide a basis for the structure and style design of yoga pants, and realize the rationality and efficiency of clothing design.

该研究分析了瑜伽下女性四肢的皮肤变形，并建立了基于皮肤变形的纬编无缝瑜伽裤数字设计模型。选择了五个代表性的瑜伽动作。选择八名女性参与者以执行标准的站立姿势和瑜伽姿势。使用三维扫描技术测量参与者的下肢，并分析下肢不同部位的皮肤数据。根据皮肤变形数据对无缝裤原型进行分区，建立纬编无缝瑜伽裤分区设计模型。通过创建织物结构库并根据织物结构的拉伸特性对其进行分类，建立模型分区与织物结构分类之间的对应关系，实现了无缝瑜伽裤结构的数字化设计。研究结果可为瑜伽裤的结构和款式设计提供依据，并实现服装设计的合理性和有效性。
