Abstract
Abstract A tufted pile floor covering is formed of a flexible polymeric base having a pile composite embedded therein. The pile composite is formed of a primary woven pile backing through which loops of the piling project. The piling is a coated fibrous material. In a preferred embodiment, the coating on the piling is chemically similar to the flexible polymeric base material. In assembling the piling composite on the base, portions of the piling loops projecting on one side of the primary backing are embedded in the flexible polymeric base creating a mechanical lock. Further, when the coating on the piling fibers is chemically compatible with the base material the coating is fused with the material of the flexible polymeric base. Thus, both a chemical and a mechanical lock are achieved between the piling and the flexible polymeric base.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A floor covering composite having a base layer for contacting a floor and a pile portion adapted to be trod upon and comprising: a fluid impermeable, flexible polymeric base layer adapted to contact a floor surface; an intermediate woven primary pile backing supported on the upper surface of said base layer; and a looped piling material tufted into said intermediate primary pile backing, the piling having exposed loops above said backing and piling portions projecting below said backing, the piling portions below said backing being embedded in said flexible polymeric base layer, said piling being formed from threads having a reinforcing inner fibrous core and an exterior poly(vinyl chloride) coating, said inner fibrous core having a tensile strength greater than the tensile strength of said exterior coating, said piling portions below said backing being mechanically locked with said base layer.
Claim 2
Dependent Claim
140 words
A floor covering composite having a base layer for contacting a floor and a pile portion adapted to be trod upon and comprising: a fluid impermeable, flexible polymeric base layer adapted to contact a floor surface; an intermediate woven primary pile backing supported on the upper surface of said base layer; and a looped piling material tufted into said intermediate primary pile backing, the piling having exposed loops above said backing and piling portions projecting below said backing, the piling portions below said backing being embedded in said flexible polymeric base layer, said piling being formed from threads having a reinforcing inner fibrous core and an exterior poly(vinyl chloride) coating, said inner fibrous core having a tensile strength greater than the tensile strength of said exterior coating, said piling portions below said backing being mechanically locked with said base layer.
Claim 3
Dependent Claim
44 words
The floor covering composite as set forth in claim 1 wherein said flexible polymeric base layer and said polymeric coating on said piling are chemically compatible and the polymeric base and coating are fused with each other to create an adherent chemical bond therebetween.
Claim 4
Dependent Claim
26 words
The floor covering composite as set forth in claim 2 wherein said flexible polymeric base layer and said polymeric coating are both vinyl chloride plastic materials.
Claim 5
Dependent Claim
43 words
The floor covering composite as set forth in claim 3 wherein said vinyl chloride plastic material for said flexible polymeric base and polymeric coating are independently selected from a group consisting of homopolymers of vinyl chloride, copolymers of vinyl chloride, and mixtures thereof.
Claim 6
Dependent Claim
23 words
The floor covering composite as set forth in claim 2 wherein said base layer comprises a copolymer of vinyl chloride and vinyl acetate.

Claim 11
Dependent Claim
20 words
The floor covering composite as set forth in claim 6 wherein said primary pile backing is a woven pile backing.
Claim 12
Dependent Claim
17 words
The floor covering composite as set forth in claim 1 wherein said primary pile backing is nonwoven.
Claim 13
Dependent Claim
25 words
A floor covering composite as defined in claim 1 wherein said inner fibrous core comprises a bundle of fibers having a poly(vinyl chloride) coating thereon.
Claim 14
Dependent Claim
137 words
