Abstract

The present invention relates to a tufted fabric and a method of manufacturing the same. The tufted fabric generally comprises a primary backing and tufts mounted in the primary backing to form a fabric with a faceside having piles and a backside having loops. A thermoplastic polymer adhesive, which bonds the tufts to the primary backing, is formed by applying a reactive mixture comprising a polymerizable monomer to the backside of the tufted fabric and in-situ polymerizing the monomers to form the thermoplastic polymer adhesive. The process is particularly advantageous for the manufacture of recyclable tufted fabrics in which the adhesive polymer and tufts are formed from substantially the same polymer. The tufted fabric can be used in articles, such as, for example carpets, rugs and upholstery.

Dependent claims

A process for forming a tufted fabric comprising the steps of:

mounting tufts in a primary backing having a faceside and a backside, said tufts forming piles at said faceside and loops at said backside of said primary backing;
applying a reactive mixture to at least said loops on said backside of said primary backing, said reactive mixture comprising a polymerizable monomer;
and
in-situ polymerizing said monomer to obtain a thermoplastic polymer adhesive, said thermoplastic polymer adhesive binding said tufts to said primary backing.
