The structure of rayon fiber is generally that of smooth, inelastic filaments like glass rods. However, different processes, additives and finishes can vary the physical appearance and structure of viscose rayon.
Chemical formula of viscose rayon obtained by reacting cellulose with alkali and carbon disulphide CS2 is as follows:
Different kind of fibers can be identified by their microscopic appearance better, than their physical appearance. When viscose rayon is viewed under microscopic lens;
- The longitudinal appearance of regular viscose rayon exhibits uniform diameter and interior parallel lines called striations.
- In cross section view, viscose fiber shows highly irregular or serrated edges.
