Abstract: A method for preparing cellulose dope from textile waste including cellulose fibers in a mass percentage of more than 50%. The method includes shredding the textile waste in order to obtain a first mixture of shredded fibers and residues, separating at least a portion of the non-cellulosic components from the first mixture in order to obtain a second mixture in which the mass percentage of cellulose fibers is greater than the mass percentage of cellulose fibers in the first mixture, filtering the second mixture in order to recover a solid phase including the cellulose fibers, dissolving the cellulose fibers of the solid phase so as to obtain a cellulose dope including undissolved particles, and filtering the cellulose dope in order to obtain a cellulose dope that is separated from the undissolved particles.
