Title
(EN) RECYCLING OF COMPOSITES CONTAINING LAYERS UNSUITABLE FOR RECYCLING
(FR) RECYCLAGE DE COMPOSITES CONTENANT DES COUCHES INAPPROPRIÉES POUR LE RECYCLAGE
Abstract
(EN)
An added layer attached to a textile sheet using polymeric adhesive placed over a textile sheet or between the textile sheet and an added layer is removed by applying heat or a solvent and at least one of an abrasive action, squeezing, or shaving action to remove the adhesive layer or both the added layer and the adhesive sublayer and to prepare the textile sheet for recycling into a new textile structure, preferably into a textile sheet performing the same function as the original textile sheet.
(FR)
Une couche ajoutée fixée à une feuille textile à l'aide d'un adhésif polymère placé sur une feuille textile ou entre la feuille textile et une couche ajoutée est retirée par application de chaleur ou d'un solvant et d'au moins une action parmi une action abrasive, un pressage, ou une action de rasage pour retirer la couche adhésive ou aussi bien la couche ajoutée que la sous-couche adhésive et pour préparer la feuille textile pour un recyclage en une nouvelle structure textile, de préférence en une feuille textile réalisant la même fonction que la feuille textile d'origine.
