MCQ Detailed View

Artificial or man-made fibers are fibers produced from chemical substances rather than obtained directly from plants or animals. Rayon is one of the most widely used artificial fibers. It is made from cellulose, which is chemically treated to produce fibers with properties similar to natural silk, cotton, or wool.

Rayon is manufactured through processes that involve dissolving cellulose in chemicals, regenerating it into fibers, and then spinning it into threads. It is called semi-synthetic because it originates from natural cellulose but undergoes chemical transformation. Rayon is smooth, soft, and absorbent, making it suitable for textiles, clothing, upholstery, and industrial applications.

Other options listed in the question are not fibers. Boron is an element, saffron is a natural spice derived from flowers, and “None of these” is incorrect. Rayon is recognized worldwide as a key example of a man-made fiber.

The production of rayon involves important organic chemistry principles, including chemical modification of natural polymers, esterification, and regeneration of cellulose. Understanding man-made fibers is important for students studying organic chemistry, polymer chemistry, and industrial applications.

Rayon’s artificial nature allows manufacturers to produce fibers with specific qualities such as strength, texture, and dyeing ability, which are difficult to achieve with natural fibers alone. It highlights how chemical processing can create useful materials for daily life.

Therefore, among the options given, rayon is an artificial man-made fiber, demonstrating the application of organic chemistry in textile production and material science.
