Rayon can be made by extruding viscose though a hole rather than a slit.
The alpha type of this cannot be dissolved in a 17.5% solution of sodium hydroxide at 20 degrees Celsius. It is a straight chain polymer derived from beta-glucose, whose hydroxyl groups form hydrogen bonds with each other, contributing to its high tensile strength. In 1908, a Swedish textiles engineer treated it with alkali and carbon disulfide to create viscose, which was extruded through a slit to create a clear film. Rayon can be made by extruding viscose though a hole rather than a slit. In vascular (*) plants it is synthesized at the cell membrane by rosette terminal complexes. Although it cannot be digested by humans, it acts as a dietary fiber, absorbing water and making defecation easier. Some animals, for example cows and termites, can digest it with the help of certain micro-organisms. FTP, name this structural polysaccharide found in the cell walls of green plants.
