Process and system for reclaiming polymeric fibers (e.g., nylon) from post-consumer carpeting includes shredding the post-consumer carpeting into strips, dismantling the carpet strips to form a mixture of the fibers to be reclaimed and the backing material to be discarded, and then separating a substantial portion of the fibers from the backing material. Preferably, the carpet strips are dismantled by impacting the strips of carpeting against an anvil structure with hammer elements using, e.g., a hammermill. A secondary reclamation system is provided whereby the separated backing material which may contain some fibers bound thereto is subjected to secondary dismantling and separation operations. The fractions obtained from the primary and secondary separation operations containing predominantly the polymeric fibers may thus be combined so as to form a process discharge stream which can be pelletized and/or baled as desired.

Cette invention concerne un procédé et un système de recyclage des fibres polymères (par ex. nylon) de moquettes usées. Les étapes du procédé sont les suivantes : réduction des moquettes en lanières, déchiquetage des lanières pour former un mélange de fibres à recycler et de matériau d'envers de moquette à éliminer et séparation d'une partie importante des fibres du matériau d'envers. De préférence, le déchiquetage des lanières de moquette se fait par frappe des dites lanières contre une structure enclume, dans un broyeur à marteaux par exemple. Un système de recyclage secondaire est prévu où le matériau d'envers traité une première fois est soumis à un deuxième déchiquetage et une deuxième opération de séparation des fibres. Les fractions obtenues lors des opérations primaire et secondaire de séparation et renfermant en majeure partie des fibres polymères peuvent ainsi être combinées en un flux unique se prêtant à la pelletisation et/ou la mise en balles, au choix.
