Abstract:
The invention pertains to a nonwoven primary carpet backing comprising thermoplastic polymer filaments or fibres bonded by means of a binder polymer, wherein the backing comprises at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer also comprising filaments or fibres bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30 % and preferably by at least 50 %, with respect to the same backing without the said distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted prior art backings, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted prior art backings.
Abstract:
A carpet underlay comprising a fibrous nonwoven substrate composed of natural or synthetic fibers having in or on it a repellent finish which makes said substrate substantially impervious to liquids, and a carpet having an underlay substantially impervious to liquids affixed to the carpet back rendering said carpet substantially impervious to liquids are disclosed.
Abstract:
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 sheet 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.
