Effects of washing on the mechanical properties of medical compression stockings

Abstract

The performance of medical compression stockings can undergo notable changes after washing. This study aimed comprehensively to evaluate how the mechanical properties of medical compression stockings would be changed after undergoing washing under different conditions. We further investigated the effect of washing parameters on medical compression stockings. By subjecting medical compression stockings to washing under varying conditions, and measuring the mechanical properties (including the tensile properties, bending property, friction property, and bagging property) of medical compression stockings from the knee to the thigh, distinct alterations were observed. Notably, it was concluded that the elongation, the tension, and the bending rigidity of medical compression stockings increased. In addition, the residual rate of bagging was reduced after washing. In addition, the washing temperature was the most significant factor affecting the mechanical properties of medical compression stockings. Meanwhile, the mechanical actions of the washing machine, such as drum speed and washing time, also exerted varying degrees of influence on the mechanical properties of different medical compression stockings. Furthermore, this study not only provides essential guidance for consumers regarding effective washing practices for medical compression stockings, but also contributes valuable insights towards optimizing the mechanical properties of medical compression stockings to maintain their key properties.
