Fabric deformation occurs as a result of stress relaxation induces disturbances in textile function. Pressure garments, pressure bandages, and varicose stockings are some textiles whose performance is affected by the stress relaxation in the components of a fabric. In this study, we investigate the effect of fabric structure on the stress relaxation of weft-knitted fabrics. Rib knitted fabrics with different miss stitches in successive wales were fabricated, and their stress relaxation was evaluated in both course and wale directions. The results show that the fabric structure significantly affects the stress relaxation. As the number of miss stitches increases, the fabric stress relaxation increases in both course and wale directions. In all fabric structures, stress relaxation is higher in the wale direction than that in the course direction. Utilization of the miss stitch in the structure of compression garments, varicose stockings, and pressure bandages is not recommended since miss stitch diminishes their functionality as a result of stress relaxation.

织物变形是由于应力松弛引起织物功能紊乱的结果。压力服、压力绷带和静脉曲张袜是一些纺织品，其性能受织物成分应力松弛的影响。在这项研究中，我们研究了织物结构对纬编针织物应力松弛的影响。在连续纵行中制造具有不同漏针的罗纹针织物，并在横列和纵行方向评估它们的应力松弛。结果表明，织物结构显着影响应力松弛。随着漏针数量的增加，织物在横列和纵行方向上的应力松弛都会增加。在所有织物结构中，纵行方向的应力松弛比横列方向的应力松弛要高。
