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

Answer 1

Answer: (B), (C)

The correct options are
B Burn and smell the fumes of the clothes
C Feel the texture of cloth

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