MCQ
What are blended fibres?
- AMixture of two natural fibres
- BMixture of two synthetic fibre
- CMixture of natural and synthetic fibres
- ✓All of above
✓
Answer
Correct option: D.
All of above
Blended fibres are made by combining various fibres to enhance the property of the product.
For eg: spandex and cotton is a natural mix for sports clothing and undergarments to improve stretching properties and prevent odour.
A blended fabric helps overcome the disadvantages of natural and synthetic fibre.
