Question

Which of the following is a disadvantage of synthetic fibre?

• A. melt before burning
• B. repel moisture
• C. clothes are garishly lustrous
• D. All of the above

Answer 1

The correct option is D All of the above

Clothes made of pure synthetic fibres are garishly lustrous. Synthetic fibres melt before burning. So clothes made of such fibres stick to the skin when in contact with a flame, causing burns. Therefore, they should not be worn in the kitchen or while setting off fireworks.

Synthetic fibres are generally hydrophobic, i.e., they repel moisture (e.g., sweat) and do not absorb it. They do not allow enough circulation of air either. So clothes made of synthetic fibres are not comfortable to wear as they do not allow sweat to evaporate easily.
