Abstract
Abstract A floor mat comprising: a hydrophilic flocking adhesive, flock fibers, a thin primary backing selected from nonwoven, woven and polymeric film substrates, a laminating adhesive and a foam secondary backing. The flock fibers are bonded to the primary backing with the hydrophilic flocking adhesive. The primary backing is laminated to the foam secondary backing with the laminating adhesive. The hydrophilic flocking adhesive improves the wet soil absorbency of the mat.
