Performance Characterization of Compression Socks at Ankle Portion under Multiple Mechanical Impacts

The aim of this research is to investigate how performance of compression socks is deteriorated due to expected induced wearing mechanical impacts. Wearing mechanical impacts influence the durability parameters i.e. tensile energy loss, extent of pressure deterioration and dimensional deformation. This research is comprised of two parts; 1): Comparison of unwashed and hand washed cut-strips for tensile energy and dimensional deformation. For tensile energy loss, cut-strip samples were-interacted to constant rate of loading and un-loading, cyclic-loading upto 15th cycles for +/- 5 mm extension (considering muscles expansion and relaxation) and were dwelled (stayed) for 3 minutes at 25%, 50% and 75% extension levels, simultaneously. As a second part 2); Three levels (1st, 2nd and 3rd) of gradual intensive machine washes were performed to quantify the extent of deterioration of compression pressure, worn alternatively on a fixed sized plastic leg, using KIKUHIME pressure measuring device. Dimensional deformation due to hand washing while dimensional recovery; immediately after pressure measurement (after Pr.), and a-day-later after pressure measurement (dL Pr.) was compared and statistically analyzed. Statistical validation of second part was performed by introducing measures of correlation, p-value ( 0.05), R-square values using MINITAB 17 software.
