Abstract:
1. A personal care article for contact with human skin upon movement of the article over the skin at a movement speed of the article relative to the skin, said article comprising: a non-woven substrate having a longitudinal direction, a transverse direction and at least one skin-contact surface; a plurality of surface features disposed on the at least one skin-contact surface in a sinusoidal wave-form along at least one of the longitudinal direction and the transverse direction of the substrate, the surface features having a uniform height that generally defines an amplitude of the sinusoidal wave-form, said height being in the range of about 0.1 microns to about 30 microns, said surface features being spaced from each other a spatial distance, said spatial distance being at least in part a function of the movement speed at which the article is to be moved relative to the skin while in contact therewith.
