Friction Behaviour of Medical Compression Stockings Against Various Mechanical Skin Models
To determine a promising skin model for exploring the friction behaviour of medical compression stockings (MCS), the dynamic friction properties of MCS against with two kinds of mechanical skin models are investigated in the current study. For further investigation, the difference on the friction of the two models are analysed in detail with adhesion friction model and Hertz contact theory. The coefficient of friction (COF) of MCS/Lorica is 0.34 ± 0.01, which is closer to the COF of human skin/MCS (0.36 ± 0.04), while the COF of MCS/PUR is 0.89 ± 0.01, with an increasing factor of 2.6, mainly due to the variation of elastic modulus. It can be concluded that Lorica has similar dry friction behaviour as the human skin, and elastic modulus could be the main reason to the difference on the friction of two models.
