Answer 2

Artificial silk (Rayon) is formed from cellulose which is obtained from wood pulp, this cellulose is then dissolved in a substance called alkaline carbon disulphide to make a thick liquid. It is then squirted into a pool of acid, this creates a fibre exactly like silk.

Artificial silk (Rayon) has become more popular than natural silk because

1. It is less expensive than silk.

2. It absorbs moisture and is comfortable to wear.

3. It blends well with other fibres, particularly woven ones

4. It can be easily dyed to produce beautiful and vivid colours.
