Rayon - The generic term
for fibers, staple, and continuous filament yarns composed
of regenerated cellulose but also frequently used to
describe fibers obtained from cellulose acetate or cellulose
triacetate. Rayon fibers are similar in chemical structure
to natural cellulose fibers (e.g., cotton) except that
the synthetic fiber contains shorter polymer units.
Most rayon is made by the viscose process.
