Discussion
Read the following statements carefully and select the correct option.
S1 : Rayon is a synthetic fibre.
S2 : Rayon is made without using any natural raw material.
Answer: B
S1 is true and S2 is false.
Rayon is classed with synthetic (man-made) fibres in the school syllabus because it is made in factories by chemically treating a raw material; it resembles silk and is called artificial silk.
But the raw material is natural: rayon is made from cellulose obtained from wood pulp. So S2, that no natural raw material is used, is false. That is why rayon is often described as semi-synthetic.
