A process which comprises suspending a reactive-dyed cellulose material, optionally in mixture with pulp, in an alkali metal hydroxide solution (alkali cellulose), optionally subjecting the alkali cellulose to the action of a reducing sulfur compound at a temperature from 20 DEG to 80 DEG C., then allowing the alkali cellulose to ripen at temperatures from 30 DEG to 80 DEG C. for at least 30 minutes, dissolving the alkali cellulose at a temperature from 10 DEG to 30 DEG C. by conversion with carbon disulfide into the xanthate, and spinning the xanthated alkali cellulose into fibers, makes it possible to recycle cellulosic waste textiles into similarly colored or colorless cellulose fiber materials.
