Question

• if rayon is a synthetic fiber that why it does not form a bead during the process of heating ?
• it says that all synthetic fiber form a bead so rayon is a synthetic fiber?

Answer 1

1. It is true that synthetic fibres form bead when they are heated. This is because,the bonds in them is broken down easily and they start melting down.
2. But this is not true for natural fibres. This is because they are made of complex network of bonds.
3. Rayon is not a purely synthetic fibre. It is a semi-synthetic fibre that is derived from wood pulp in the form of cellulose and then some reactions are carried out to increase its efficiency as fibre. Thus it does not form a bead when heated.
