Abstract:
A method for forming an abrasion resistant paper sheet for use in decorative laminates comprising the steps of:mixing cellulosic, fibrous feedstock and water to form a first cellulosic slurry; depositing said first cellulosic slurry onto a wire of a papermaking machine to form a base paper web; mixing encapsulated or non-encapsulated particles with water to form a grit slurry; depositing said grit slurry on said base paper web; mixing cellulosic, fibrous feedstock and water to form a second cellulosic slurry; depositing said second cellulosic slurry onto said grit slurry at a sufficient distance from the deposition position of said grit slurry and the deposition position of said first cellulosic slurry so that said second cellulosic slurry forms a discrete fiber layer on top of the two previously deposited layers thereby forming a wear resistant paper product having three discrete layers; and printing or coating a desired pattern on a top (felt) side or bottom (wire) side of said wear resistant paper product.
