A recyclable tufted carpet (20) meeting EPA recyclable content standards and having improved dimensional stability that reduces skew, bow, and wrinkles during manufacture and installation is formed by combining prior art primary and secondary backings into a single, fiber-reinforced primary backing layer (24). Consolidating either a glass fiber fabric layer (26), a glass veil (128), or a glass mat (158) with a fiber-reinforced extruded film (28) forms the fiber-reinforced primary backing layer. An additional glass fabric fiber layer can also be introduced to the primary backing to provide additional dimensional stability.

L'invention concerne une moquette touffetée recyclable (20) répondant aux normes de contenu recyclable de l'Agence de protection de l'environnement (EPA) et présentant une stabilité dimensionnelle améliorée permettant de réduire l'asymétrie, le cintrage et les plis pendant la fabrication et l'installation. La moquette selon l'invention est constituée des supports primaire et secondaire des antériorités, mais ils sont réunis en une couche de support primaire unique, renforcée par des fibres (24). La consolidation d'une couche de tissu de fibres de verre (26), d'un voile de fibres de verre (128) ou d'un mat de fibres de verre (158) au moyen d'un film extrudé renforcé par des fibres (28) permet d'obtenir ladite couche de support primaire. Une couche de tissu de fibres de verre supplémentaire peut également être intégrée dans le support primaire afin d'obtenir une stabilité dimensionnelle accrue.
