Abstract[English]
A technique is described for recycling polyester and cellulosic fibers from textiles and cloth waste that contain a combination of both types of fibers. The process employs anhydrous HCl and a thermal range of 35-80°C to treat the cloth and textile waste. During the process, the cellulose content is converted into a fine dry powder, and the polyester fiber is separated from the cellulosic ones. The cellulosic material can be either cotton or artificial silk. Mechanical destruction can be involved in the process. Finally, the polyester fibers are extracted from the cellulosic material.[French]
Une technique est décrite pour recycler des fibres de polyester et de cellulose à partir de déchets de textiles et de vêtements qui contiennent une combinaison des deux types de fibres. Le procédé utilise du HCl anhydre et une plage thermique de 35 à 80 °C pour traiter les déchets de textiles et de vêtements. Pendant le processus, la cellulose contenue est convertie en une fine poudre sèche, et la fibre de polyester est séparée des fibres cellulosiques. Le matériau cellulosique peut être du coton ou de la soie artificielle. La destruction mécanique peut être utilisée pendant le processus. Enfin, les fibres de polyester sont extraites du matériau cellulosique.
