See full text

A method of obtaining rayon fibers from cellulose waste is provided. The method includes extracting alpha-cellulose from cellulose waste, dissolving the alpha-cellulose in a cuoxam solution, obtained by reacting gaseous ammonia with an aqueous solution of copper hydroxide, to obtain a chemically modified cellulose. The chemically modified cellulose was extruded in an acid bath to obtain a precipitate. The precipitate was further neutralized to obtain the rayon fibers.
