This study analyzed leggings patterns and materials and evaluated user satisfaction with movement, wear comfort, and compression by body part and posture while wearing leggings. We also examined the stress strain through a 3D virtual fitting. To perform the test, 7/8 leggings, which are the most preferred style among middle-aged women in their 40 s and 50 s, were selected. The leggings comprised stretch knit material mixed with nylon and polyurethane (PU). Five subjects were asked to wear a random pair of test leggings and evaluate their satisfaction with movement, wear comfort, and compression by body part and posture on a 5-point scale, where the postures were walking freely, 90°one-sided leg flexion, bent-legs crouching, and sitting on a chair position. Overall, there were statistically significant differences in satisfaction at the level of p < .05. According to the maximal elongation rate of the skin and the rate of increase of the body surface area by body part, the higher the proportion of stretchable and elastic PU in the leggings, the higher the wearers’ satisfaction, while the lower the proportion of PU with the aforementioned properties, the lower the satisfaction level. Specifically, by body part, satisfaction with wear comfort in the waist and abdomen was high for the material composition 63% nylon and 37% PU and for 79% nylon and 21% PU and 74% nylon and 26% PU in the hip, crotch, and thigh areas, while the lowest satisfaction with all body parts was reported for 84% nylon and 16% PU. Moreover, satisfaction with waist compression decreased as the proportion of PU increased. Regarding abdominal compression, an area which may have considerable subcutaneous fat, the range of pressure applied on this part of the body dispersed as the material stretched in the course direction, decreasing the subjects’ sense of the clothing’s constraint. According to the result of stress strain testing using a color distribution chart in 3D virtual fitting, stress strain was the highest for the material composition 84% nylon and 16% PU, which was represented in red. In contrast, it was low for 63% nylon and 37% PU, represented in yellow and green. Stress had an inverse relationship with the textile’s stretchability. In summary, the effect of the characteristics of stretch knit material on different body parts differed depending on the direction of movement and the elasticity of the material, and user satisfaction was influenced by changes in the curvature of the individual’s body, as well as the elasticity and movement direction of the material.

这项研究分析了紧身裤的图案和材料，并评估了用户对运动、穿着舒适度以及穿着紧身裤时身体部位和姿势的压缩的满意度。我们还通过 3D 虚拟拟合检查了应力应变。为了进行测试，选择了 7/8 打底裤，这是 40 多岁和 50 多岁的中年女性最喜欢的款式。该打底裤由弹力针织材料与尼龙和聚氨酯 (PU) 混合而成。要求五名受试者随机穿着一条测试紧身裤，并以 5 分制的方式评估他们对运动、穿着舒适度以及身体部位和姿势的压缩的满意度，其中姿势为自由行走、单侧腿部弯曲 90° ，双腿弯曲蹲下，坐在椅子上的姿势。总体而言，不同层次的满意度存在统计学上的显着差异。p < .05。根据皮肤的最大伸长率和身体部位的体表面积增加率，打底裤中具有拉伸性和弹力的PU比例越高，穿着者的满意度越高，反之PU的比例越低具有上述属性的情况下，满意度越低。具体来说，从身体部位来看，腰部和腹部的穿着舒适度满意度较高，材质成分为63%尼龙+37%PU，臀、裆为79%尼龙+21%PU，74%尼龙+26%PU。和大腿区域，而对所有身体部位的满意度最低的是 84% 尼龙和 16% PU。此外，随着PU比例的增加，腰部压缩满意度下降。关于腹部受压，该区域可能有大量皮下脂肪，当材料沿路线方向拉伸时，施加在身体这一部分上的压力范围会分散，从而减少受试者对衣服的束缚感。根据3D虚拟试衣中使用颜色分布图进行应力应变测试的结果，材料成分84%尼龙和16%PU的应力应变最高，以红色表示。相比之下，63% 尼龙和 37% PU 的含量较低，以黄色和绿色表示。应力与纺织品的拉伸性成反比关系。综上所述，弹力针织材料的特性对不同身体部位的影响因运动方向和材料的弹性而异，而用户满意度则受到个人身体曲率变化的影响，
