Cellulose rayon is not a natural polymer. Rayon is an artificial textile material composed of regenerated and purified cellulose derived from plant sources. It is described as a regenerated fibre because the cellulose obtained from softwoods or from the short fibres (linters) that adhere to cottonseeds, is converted to a liquid compound, squeezed through tiny holes in a device called a spinnerette and then converted back to cellulose in the form of fibre.
