Abstract

La invencion se refiere a un procedimiento para reciclar residuos de alfombras que contienen poliamida extrayendo la poliamida del residuo de alfombras con un agente de extraccion que contiene un alcohol alifático, después de lo cual se recupera la poliamida del extracto. El procedimiento de acuerdo con la presente invencion proporciona un alto rendimiento de poliamida. La presencia de otros constituyentes usados normalmente en la fabricacion de alfombras no interfiere con el reciclado.
