Carpet having nonwoven fleece adhered to secondary backing by embossing and method of making same

A floor covering comprising a carpet having textile fibers defining a fibrous upper outer face and a primary backing to which the textile fibers are secured, a secondary backing permanently adhered to the lower surface of said primary backing, a nonwoven fleece fabric positioned against said secondary backing and being embossed so as to form high and low areas with the low areas extending into said secondary backing and serving to unitize the fleece fabric with the secondary backing, a layer of permanent adhesive between said secondary backing and said fleece fabric to aid in securing said fleece fabric to said secondary backing, a layer of pressure sensitive adhesive on the exposed outer face of said fleece fabric for releasably securing the floor covering to an underlying floor, and with the low areas in the embossed fleece fabric serving for reducing the effective exposed surface area of the layer of adhesive that is available to contact the underlying floor when laying of the floor covering thereon.

A method of making a floor covering such as a carpet with pressure sensitive adhesive thereon for facilitating installation and wherein the carpet has textile fibers defining a fibrous upper outer face, a primary backing to which the textile fibers are secured, and a secondary backing permanently adhered to said primary backing, said method comprising positioning a nonwoven fleece fabric in overlying relation with the secondary backing, then embossing the nonwoven fleece fabric while supplying sufficient heat and pressure to form high and low areas with the low areas extending into the secondary backing to effect securement of the fleece fabric to the secondary backing, applying a layer of pressure sensitive adhesive to the outer face of the fleece fabric for releasably securing the floor covering to an underlying floor when laying of the floor covering on the underlying floor, and with the low areas in the embossed fleece fabric serving to reduce the effective exposed surface area of the layer of adhesive that is available to contact an underlying floor when laying of the floor covering thereon.

A method of making a floor covering such as a carpet with pressure sensitive adhesive thereon for facilitating installation and wherein the carpet has textile fibers defining a fibrous face, a primary backing to which the textile fibers are secured and a secondary backing permanently adhered to the primary backing, said method comprising applying a layer of permanent adhesive to one face of a nonwoven fleece fabric, positioning the secondary backing into engagement with the layer of permanent adhesive on the fleece fabric, embossing the nonwoven fleece fabric while supplying sufficient heat and pressure to form high and low areas with the low areas extending into the secondary backing to effect securement of the fleece fabric to the secondary backing, applying a layer of pressure sensitive adhesive to the fleece fabric for releasably securing the floor covering to an underlying floor and with the low areas in the embossed fleece fabric serving to reduce the effective exposed surface area of the adhesive that is available to contact the underlying floor when laying of the floor covering thereon.
