Abstract

Tanned leather is dry dressed by plasma deposition at atmospheric pressure of a matrix material such as ITO, a silicone, or polyurethane, upon the protein fibers of the surface of the leather and the collagen fiber skeleton below the surface protein fibers. The leather retains its toughness, elasticity, breathability and softness or hand.
