Protective stretch coating having controlled moisture permeability and color

Abstract

A coated textile system comprising a fibrous substrate coated by an elastomer mixed with inorganic particles provides good drape and bending with very high cut resistance. The substrate can include conventional and/or high performance fibers. The elastomer includes particles of at least two sizes, and in embodiments three or more sizes, which fill in gaps between the largest particles and prevent a blade from pushing the particles aside and passing between them. The coating can be applied directly to the substrate, or pre-formed and adhered thereto. Particles can be pigmented, to impart a color to the textile. Pin holes formed by the particles and/or by mechanical manipulation can increase MVT. An elastomeric cover layer can enhance grip and/or reduce MVT. A plurality of layers of coated textile can be combined, in embodiments attached only about their perimeters, to provide even higher levels of cut resistance without sacrifice of bendability.
