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.
