Velvet-like structures can be achieved by flocking. Thereby metal, wood or textile substrates are coated with an adhesive onto which the fibers are applied. The treatment of the surface of a substrate by fibers is carried out in an electrostatic field. Mostly small holes in the adhesive coat on the surface of the substrate result, thereby increasing its porosity. Flocking is carried out in the following way: a fabric, cardboard or leather is coated with an adhesive coat. Usually viscose fibers are either sprayed by air or in an electrostatic field [22] onto the coated surface. [9, 28]. Flocking [1] does not create eo ipso water vapor permeability.
