Abstract
Methods for forming a hydroentangled scrim sheet are provided. The method can include hydroentangling a scrim sheet having a first layer of staple fibers on a first side of the scrim sheet and a second layer of staple fibers on a second side of the scrim sheet to form a hydroentangled scrim sheet; calendaring the hydroentangled scrim sheet to form a calendared hydroentangled scrim sheet; impregnating the hydroentangled scrim sheet with a saturant composition; drying the saturant composition impregnated into the calendared hydroentangled scrim sheet; applying a bond coat onto a surface of the calendared hydroentangled scrim sheet; and applying a top coat onto the bond coat. The top coat is, in one embodiment, configured to provide a surface for further coatings thereon.
