How a thread of rayon is formed |
| Answer» Rayon is a man-made fiber prepared from a natural raw material called cellulose by chemical treatment. The cellulose required for making rayon is obtained from wood pulp. Rayon is obtained by the chemical treatment of wood pulp.1)Wood pulp is dissolved in an alkaline solution to form sticky liquid called viscose.2)Viscose is forced to pass through the tiny holes of metal cylinder into a solution of sulphuric acid when a silk like thread of rayon is formed.Rayon is made from naturally occurring polymer present in wood pulp, therefore rayon is neither a fully synthetic nor a fully natural fiber. It is a semi-synthetic fiber. | |
