Question

_________is the first fully synthetic fibre, developed by Wallace Carothers.

• A. Polyester
• B. Rayon
• C. Acetate
• D. Nylon

Hint:

Nylon, invented by Wallace Carothers, was the first fully synthetic fibre revolutionizing textiles.

Answer 1

The Correct Option is D

Nylon, a product of Wallace Carothers' and his DuPont team's 1930s research, holds the distinction of being the inaugural fully synthetic fiber. Its development represented a pivotal advancement in textile production due to the following characteristics:

It is entirely artificial, synthesized from petrochemical sources.
It exhibits superior strength, elasticity, and resilience.
Its applications are extensive, found in textiles, cordage, and industrial components.

Analysis of Alternative Choices:

(A) Polyester: A synthetic fiber developed subsequent to Nylon.
(B) Rayon: A semi-synthetic fiber created through the regeneration of cellulose.
(C) Acetate: A semi-synthetic fiber derived from cellulose acetate.
Consequently, the accurate selection is (D).
