Abstract
Abstract Disclosed in an article comprising flock fibers adhesively bonded to a thin, heat stable, flexible, water-impermeable, polymeric film. The preferred article is a flocked floor mat with good water and wet soil absorbency and door clearance: a preferred mat comprises short fibers bonded, with a hydrophilic adhesive, to the thin polymeric film which in turn is preferably laminated to a thin foam secondary backing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A floor mat comprising a thin, flexible polymeric film primary backing, a flocking adhesive, and assembled flock fibers, the fibers being bonded to the primary backing with the flocking adhesive; wherein the film is a water-impermeable, polymeric film, said film being dimensionally stable under flocking adhesive curing conditions; wherein the flexible polymeric film is selected from the group consisting of polycarbonate, nylon, polyester, polypropylene, and other suitable flexible films, said film having a thickness of at least 0.005 mm, and wherein said adhesive is coated on said film at a thickness of at least 0.1 mm prior to flocking, and wherein the fibers are flocked onto the film at a level of from about 1,000 to about 40,000 fibers/cm 2 ; the fibers having lengths of from 0.4 mm to about 10 mm and a denier of from 1.5 to about 80, and wherein the flocking adhesive is cured, and the cured adhesive has a water contact angle of from 0° to 70°.
