Abstract
A process for forming an abrasion resistant, printable sheet which comprises forming a web of cellulosic fibers on a papermaking machine and applying a slurry including an abrasion-resistant grit to the upper surface of the web on the papermaking machine and then applying a secondary web of cellulosic fibers over the grit to form a three layer overlay product.
Claims12
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.
