Abstract:
1. An abrasion-resistant sheet comprising an open random fibrous web having substantially vertical fibers near a top surface, a solid binder resin intimately intermixed within the open random fibrous web, and an embossing factor greater than about 2, wherein the melting temperature of the binder resin is lower than the melting temperature of the web fibers in the open random fibrous web and wherein the web fibers and the binder resin on or near the top surface are heat treated to form a thin densified fiber-resin rich skin, wherein the thin densified fiber-resin skin is denser than other fiber-resin areas of the sheet and wherein the abrasion-resistant sheet can withstand at least about 3,000 cycles on the Wyzenbeek abrasion test using 80-grit abrasive paper and wherein the total amount of binder resin makes up less than about 23% by weight of the abrasion-resistant sheet.
