Abstract
The disclosure relates to a floor mat and method for producing the same. The floor mat includes a plurality of tufts extending from a carrier fabric which is joined by a layer of adhesive to a backing having at least one layer of vulcanized thermoplastic elastomer. The process for production of the floor mat includes applying an olefin based adhesive to the back of a primary tufted fabric which has been preheated. The process for production includes the further separate step of applying a sheet of vulcanized thermoplastic elastomer of between about 20 and 40 mils thickness with or without a layer of reinforcing material to the preheated adhesive backed primary tufted fabric. A second layer of vulcanized thermoplastic elastomer may thereafter be applied following another heating step.
