Question

If you are given two sample pieces of cloth made of synthetic silk and natural silk which look the same, which among the following tests would you employ to find which cloth is natural and which one is synthetic?

• A. Put the cloth in water
• B. Feel the texture of cloth
• C. Burn and smell the fumes of the cloths
• D. It is impossible to find out.

Answer 1

Answer: (B), (C)

The correct options are
B

Feel the texture of cloth

C

Burn and smell the fumes of the cloths

Synthetic and natural silk can have different textures. However, this is not always reliable. Burning the cloth produces odours which make it easy to identify natural and synthetic fibres. Synthetic fibres usually give out a chemical smell that can be easily distinguished.
