Abstract
A method for making a nonwoven reinforcing may for vinyl floor coverings is described. A base mat is formed from a mixture of glass fibers and polymeric binder fibers and/or powder, follows by treatment with a second water-based polymeric binder composition. The mat has been found to be highly satisfactory as a substrate for compressible vinyl floor covering.
