Pile weave carpet welding and welding with a pattern carpet tile as well as methods for their preparation

摘要

A pattern-tufted, fusion-bonded carpet, particularly a backed carpet tile, having a polymeric latex primary adhesive layer and a plurality of fibrous yarns bonded to and extending from the layer to form a face surface, the fusion-bonded carpet having a woven polyester sheet material and glass fiber tissue sheet material both secured to the primary adhesive base layer, and the fusion-bonded carpet overtufted by an overtufted pattern on the face wear surface. A method of preparing a pattern-tufted, fusion-bonded carpet which comprises overtufting a fusion-bonded carpet with the fusion-bonded carpet having a primary adhesive base layer composed of a polymeric latex material and containing a woven fiberglass and a glass fiber tissue sheet material and optionally to prepare carpet tile applying a solid, thermoplastic backing to the pattern-tufted, fusion-bonded carpet material.
