  • Patent number: 3976820
    Abstract: A pile-surfaced product is made by feeding a synthetic polymeric material and a backing web to a surface with the synthetic polymeric material between the backing web and the surface under conditions where the polymeric material is filament forming and the polymeric material adheres to the surface and bonds to the backing web, then withdrawing the backing web from that surface so that as the backing web is so withdrawn the synthetic polymeric material adheres thereto and is drawn into fibrils due to its adhesion to the surface but the fibrils remain integral with the remainder of the polymeric material which is laminated to the backing web, rendering the polymeric material non-filament forming, separating the fibrils from the surface and subsequently separating the pilous synthetic polymeric layer from the backing web.
