In this work, we detail the problems encountered and recommended associated solutions in determinig the tribological properties of fabric frictioning vis-`a-vis human skin under various conditions like dry skin, conditioned skin, and sweaty skin, to name just a few. Furthermore, we report on the necessary measurement setup to reliably determine the non-linear frictional behaviour of different fabric being the friction partner to like and other types of fabric, which are either stretched and thus mechanically loaded or otherwise untensioned and possibly hanging loose. Those cases are encountered in textiles worn under different physical activities like various sport activities or might play an important role in textile-based medical devices like surgical stockings, band?aids, etc. By analyzing various influences it can be shown that Coulomb?s law for rigid body friction must be extended to also include the dependency on parameters such as yarn orientation, skin hydration, contact force and fabric pre?stretch. The developed system is easy to use and measures reliably and reproducibly both dynamic and static friction for most typically encountered friction partners.
