Washing Characterization of Compression Socks

Abstract

Background: Compression socks are highly recommended textile garments for the exertion of compression pressure (kPa) at the ankle. They work on the principle of the highest pressure at the ankle gradually decreasing from the ankle to the calf. Aim: The aim of the current research is to analyze all of the compression sock samples (Class I, Class II, and Class III) simultaneously at various number of times of washing them. Method: All of the sock samples were washed in a standard washing machine with standard methods (ISO 6330). For the measurement of the compression pressure, a Salzmann MST MKIV pressure measuring device was used according to the RAL-GZ 387/1 method. Results: Results included the effect of multiple wearing and washing cycles (up to 20) on compression pressure, the effect of temperature (up to 100°C) on compression pressure (kPa); multiple wearing and washing cycles on the percentage of shrinkage and the effect of marking methodology on compression pressure (Kpa) were observed and are discussed in this article. The results suggest that washing is the most important factor to consider while compression socks are used for compression therapy because they directly influence the efficacy of streamline blood flow across the legs.
