Orlon fibres are made up of:

(A)Polyamide
(B)Polyacrylonitrile✓ Correct
(C)Cellulose
(D)Polyesters

Answer: (B)

Solution

Orlon is the acrylic fibre obtained by addition polymerisation of acrylonitrile,

C H_{2} = CH - CN

, usually with a peroxide initiator. The polar cyano groups along the chain attract one another strongly, which gives the fibre its wool-like warmth and its resilience. Orlon fibres are made up of polyacrylonitrile.
