Rayon fiber cross section
Web1.6.2 Rayon. Rayon is a regenerated cellulose fiber, which, although chemically similar to cotton, differs in that its molecular weight is about one-fifth and crystallinity about one-half that of cotton. These differences make the traditional or regular rayon relatively weaker and more extensible, but about twice as absorbent as cotton. http://www.microlabgallery.com/gallery/Rayon13b2XSecfixed.aspx
