Solution

Yes rayon is a man-made fibre and different from other synthetic fibres. Rayon is manufactured regenerated cellulose fibre (wood pulp). The Cellulose is treated with alkali and carbon disulfide to yield viscose rayon. Because it is produced from naturally occurring polymers and also chemically processed, it is neither a truly synthetic fibre nor a natural fibre; it is a semi-synthetic fibre. Rayon is known by the names viscose rayon and art silk in the textile industry.
