Performance Characterization and Pressure Prediction of Compression Socks

Objective of the current research is to develop the mathematical model for the prediction of compression pressure by incorporating some of new but missing variables; circumferential aspect of leg (L_c) and socks (S_c), true stress (σ_T), true/logarithm strain (ε_T), true modulus of elasticity (E_T), deformed width (W_f) at b ankle position. Socks samples were purchased, hand washed, donned, marked, sliced to loops and then cut to rectangular strips to obtain force-elongation curve at different extensions context to practical elongation. Additionally, all samples were evaluated to analyze the influnce of multiple-machine washes as well as for identification of most influential fabric parameter on compresson pressure, statistically. Standard sized wooden leg (S9=24 cm) attached with pneumatic based sensors (Salzmann MST MK IV) to medial side was used. Force-extension diagram was obtained using Testometric tensile tester. Mathematical models were developed on the basis of principle of Laplace's law. Developed two models were analyzed and comapred with two existing recently developed models statitistically using MINTAB 17 software.
