Question

If rayon is made from cellulose of wood pulp which is a natural substance then why is it known as a synthetic fibre?

Answer 1

There are two main categories of man-made fibers: those that are made from natural products (cellulosic fibers) and those that are synthesized solely from chemical compounds (noncellulosic polymer fibers). Rayon is a natural-based material that is made from the cellulose of wood pulp or cotton.

Rayon is just obtained from wood pulp but it goes through a synthetic procedure to get converted into a fibre.That is why it is synthetic fibre
