The Story of the Silkworm
Silk
Silk fibre is obtained from the cocoon of a silkworm. It takes 10 kg of the cocoon material to create 1kg of silk.
The process was discovered in China where it was kept as a closely guarded secret for a long time.
Silk is costly due to the material quality and production process involved. It is used in making sarees, ties, etc.
Raving about Rayon
Rayon
Rayon is made from purified cellulose, which is chemically converted into a soluble compound.
Rayon comes from natural sources such as wood pulp but is considered as a man-made fiber. This is because rayon can be treated chemically.
When rayon is compared with silk, it is inexpensive but can be woven like silk fibres.
