Personal care article with substrate surface topography for evoking a neurosensory skin response

摘要

In a personal care article for contact with human skin, a non-woven substrate of the article has a longitudinal direction, a transverse direction and at least one skin-contact surface. A plurality of surface features is 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 have a height that generally defines an amplitude of the sinusoidal wave- form, and are spaced from each other a spatial distance. This spatial distance is at least in part a function of a movement speed at which the article is to be moved relative to the skin while in contact therewith. In one method of making such a substrate, the movement speed and a temporal frequency are selected and used to determine the spacing between surface features on the skin-contact surface of the substrate.
