Abstract

A laminar product comprising an overlay and a base layer, the overlay including a fibrous web impregnated with a saturating resin, the base layer being a resilient resin layer or a felt or matted layer.

Claims

16-1. The laminar product of claim 1 wherein the fibers include alpha cellulose.

20. An abrasion resistant laminate comprising a felt layer and an overlay overlying the felt layer, the overlay including a fiber web impregnated with a saturating resin.

21. The laminar product of claim 20 wherein the felt layer is formed from cellulosic fibers.

22. A laminar flooring product comprising a felt layer, a foamed layer of a vinyl resin, and an overlay, the overlay being a cellulose fiber web impregnated with a saturating resin.

24. A method for forming a wear layer on a vinyl base sheet which comprises:

impregnating a cellulose web with a wear-resistant resin,

drying or curing the resin, and bonding the impregnated web to the vinyl base sheet.
