Abstract
The present invention relates to a vapor-pervious water-impervious substrate, preferably a fibrous nonwoven web, which can be used in particular as a textile continuous sheet material, for example as an awning or as an inlet in apparel. The substrate according to the present invention may have self-cleaning properties. The substrate according to the present invention is simple to produce in an at least two-step process wherein a coating on the fibers of the substrate is produced in the first step and then hydrophobic particles are applied to the coated fibers by means of an adhesion promoter.
