适应身体轮廓的可穿戴缓冲产品的制造具有挑战性。本文提出了一种控制间隔织物曲率的方法，从而促进与身体的高度贴合。弹性纱线镶嵌在其中一个表面层中，并控制喂入速率。对具有相同针织结构但不同喂入速率的5个弹性纱线样品的物理性能、弯曲性能和压缩性能进行了评价。结果表明，织物曲率与喂入速度呈线性关系。具有较低喂入速率的弯曲间隔织物具有较大的弯曲度并且较厚，但是具有较小的织物宽度以及较低的重量和密度。压缩刚度和压缩功随着曲率增加，这允许在相对更弯曲的区域（例如膝盖骨）中进行战略性缓冲。该方法可为防护服的开发提供参考。
Wearable cushioning products that accommodate the body contours are challenging to fabricate. A method that controls the curvature of spacer fabric thus facilitating a high degree of conformity to the body is proposed here. Elastic yarn is inlaid into one of the surface layers and the feeding rate is controlled. The physical properties, curvature and compression properties of five samples with the same knitted structure but different feeding rate of the elastic yarn are evaluated. The results show a linear relationship between fabric curvature and feeding rate. Curved spacer fabric with a lower feeding rate has a greater degree of curvature and is thicker, but with a smaller fabric width, and lower weight and density. The compression stiffness and work of compression increase with curvature, which allows strategic cushioning in areas that are relatively more curved, such as the kneecaps. The proposed method can contribute to the development of protective garments.
