Question

Choose regenerated fibre from the following.

• A. Rayon
• B. Cotton
• C. Silk
• D. Nylon

Hint:

Regenerated fibres like Rayon are chemically processed from natural cellulose, whereas synthetic fibres like Nylon are made from petrochemical sources.

Answer 1

The Correct Option is A

Step 1: Understanding regenerated fibres.
Regenerated fibres are made from natural materials that are processed and converted into fibres. These fibres are chemically treated to change their form, but they are still derived from natural sources.
Step 2: Analyzing the options.

• (A) Rayon: Correct. Rayon is a regenerated fibre made from cellulose derived from wood pulp or cotton. It is chemically processed to form a fibre.
• (B) Cotton: Incorrect. Cotton is a natural fibre, not a regenerated fibre.
• (C) Silk: Incorrect. Silk is a natural protein fibre produced by silkworms, not a regenerated fibre.
• (D) Nylon: Incorrect. Nylon is a synthetic fibre, not a regenerated fibre.

Step 3: Conclusion.
Since Rayon is derived from natural cellulose and undergoes a chemical process to form fibre, it is considered a regenerated fibre. Final Answer:} Rayon.
