The optimum surface and frictional properties of textiles depend on their specific application. In this study, we examined the frictional behaviour of medical wipes against 15 mechanical near skin equivalents using synthetic leather material and bovine leather. The frictional behaviour characteristics, both static and kinetic, were evaluated at four different normal loads. It was seen that the static and kinetic frictional coefficients decrease with an increasing normal load for all the reference candidates studied. Higher friction was experienced for the movement of the cotton and viscose wipe against leather than that for synthetic polyurethane (PU) and silicone material. The friction of the wipe against any equivalent skin material was found to be dependent on its surface nature and the morphology of the material against which it is in contact and moves. Friction is necessary in real-time use for a wipe to have an inherent frictional resistance for movement against skin during use.

Optymalna powierzchnia i właściwości cierne wyrobów włókienniczych zależą od ich przeznaczenia. W pracy zbadano właściwości cierne gaz chirurgicznych podczas kontaktu z mechanicznymi odpowiednikami skóry, do badań użyto syntetycznych materiałów skórzanych oraz skórę bydlęcą. Określono statyczne i kinetyczne współczynniki tarcia przy czterech różnych obciążeniach. Zaobserwowano, że oba współczynniki tarcia maleją wraz ze wzrostem obciążenia. W przypadku skóry uzyskano wyższy współczynnik tarcia, niż dla poliuretanu i materiału silikonowego. Stwierdzono, że współczynnik tarcia zależy od charakteru powierzchni i morfologii materiału, z którym styka się gaza.
