Answer:
- The source material for rayon is wood pulp and it is obtained from plant's cellulose.
- the cellulose is collected from wood or bamboo pulp and it is treated with several chemicals.
- the cellulose first treated with sodium hydroxide.(NaOH)and next with carbon disulphide (CS2).
- by dissolving in these chemicals cellulose gives syrup called viscose.
- the viscose is forced through a spinnernet into a solution of di sulpuric acid and this gives us silk like threads.
- these silk threads are cleaned with soap and dried.
7.this new fibre is called rayon which is also called as artificial silk.
