Question

Which of the following fibres are correctly matched with their properties?
1) Rayon - Wrinkle-resistant
2) Acrylic - Shrinkage-resistant
3) Polyester - High moisture absorption
4) Nylon - High strength

• A. 2 and 4
• B. 2 and 3
• C. 3 and 4
• D. 1 and 3

Answer 1

The correct option is A 2 and 4

Rayon is a semi-synthetic fibre obtained from the chemical treatment of wood pulp. It can easily get wrinkled. Therefore, it is not wrinkle-resistant.

Acrylic is a synthetic fibre which is also called artificial wool due to its resemblance in texture and feel to wool. It is resistant to shrinkage, sunlight, mildew, insects and most acids and bases. Therefore, acrylic is shrinkage-resistant.

Polyester is a synthetic fibre that is generally used in dry-fit sportswear due to its ability to dry quickly. This is due to the low moisture absorption capacity of polyester.

Nylon is a synthetic fibre known for its high strength. A nylon thread is stronger than a steel wire of the same dimensions. For this reason, nylon is used for making ropes.
