ABSTRACT A resin impregnated fibrous web is comprised of a needled fibrous batt and a polymeric resin distributed throughout the batt. The density of the impregnated web is uniform throughout with the bulk density of the web being less than the actual density of the web where- by the web is porous. The impregnated web has filaments which are both coated and uncoated with the polymeric resin. A method of form- ing the impregnated fibrous web is also disclosed. A simulated leather sheet material is produced from the impregnated web. The simulated leather sheet material is comprised of a polymer impregnated fibrous mass with a grain layer forming one surface and a split layer forming the opposing surface. The grain layer has an actual density equal to its bulk density and the split layer has a bulk density less than its actual density. The sheet material has a density decreasing from the grain layer to the split layer.
