Question

Which of the following is fully synthetic first produced fibre?

• A. Jute
• B. Acrylic
• C. Rayon
• D. Nylon

Hint:

Nylon is the world's first completely man-made fibre, invented without using any natural base like wood pulp or plant fibre.

Answer 1

The Correct Option is D

Fibres are categorized into three main types: natural fibres (e.g., cotton, jute), semi-synthetic fibres (e.g., rayon), and fully synthetic fibres (e.g., nylon, polyester).
- Jute is a natural fibre obtained from plants.
- Rayon is semi-synthetic — made from natural cellulose processed chemically.
- Acrylic is synthetic but was developed after nylon.
Nylon, developed in 1935 by Wallace Carothers at DuPont, was the first fully synthetic fibre made entirely from petrochemicals without using any natural raw material.
Nylon became widely used in making fabrics, ropes, toothbrush bristles, and even parachutes during World War II due to its strength, elasticity, and resistance to moisture and chemicals.
Hence, Nylon is the correct answer.
