Which is correct about 'Rayon'?

Options

ANatural silk
BArtificial silk
CNatural plastic or rubber
DSynthetic plastic

Correct answer

B. Artificial silk

Step-by-step solution

'Rayon' is semi-synthetic fibre which consists of purified cellulose in the form of long threads. Rayon resembles silk in appearance. Hence called as artificial silk. Cellulose → CS 2 NaOH Viscose (Syrup   like   liquid) → Spinneret into   dil .   H 2 SO 4 Pass   through Rayon (Fine   silken   thread)
