Regular rayon has lengthwise lines called striations and its cross-section is an indented circular shape. In 1952, the FTC divided rayon into two categories: fibers consisting of pure cellulose (rayon) and those consisting of a cellulose compound (acetate). Although Chardonnet’s process was simple and involved a minimum of waste, it was slow, expensive, and potentially dangerous. The first practical steps toward producing such a fibre were represented by attempts to work with the highly flammable compound nitrocellulose, produced by treating cotton cellulose with nitric acid. It is also used for making carpets and surgical dressings. Viscose Rayon is a re generated cellulosic fiber. See rayon fabric stock video clips.
