Abstract
A carpet tile and process for making the same, wherein the carpet tile comprises a facecloth having a plurality of face yarns tufted through a primary backing, an extruded polymer secondary backing layer, and a cushion, comprising a reinforcing scrim layer within a polymer layer. The top surface and bottom surface of the carpet tile are defined by the facecloth and the cushion, respectively. A polymer-based resin is extruded onto the facecloth to form an at least substantially uniform secondary backing layer, and the cushion is laid onto the extruded polymer secondary backing layer while the extruded polymer secondary backing layer remains above a softening temperature for the resin. The entire multi-layer web is then passed through a nip to embed the reinforcing scrim layer into the extruded polymer secondary layer, and the entire web is chilled.
