Rayon and its variants Rayon is produced by dissolving cellulose from wood pulp or other sources, followed by the conversion of this solution back to insoluble fibrous cellulose. Two processes have been developed for this conversion. Cuprammonium method Swiss chemist Matthias Eduard Schweizer (1818–1860) discovered that cellulose dissolves in tetraaminecopper dihydroxide.
