Question:
Which among the below mentioned fibers is not a regenerated fiber?
Which among the below mentioned fibers is not a regenerated fiber?
Show Hint
Cellulose derivatives = regenerated fibers (Rayon, Acetate, Lyocell). Nylon = synthetic.
Updated On: Sep 24, 2025

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding regenerated fibers.
Regenerated fibers are produced from natural polymers that are chemically treated and reformed into fibers. Examples: Rayon, Acetate, Lyocell (all derived from cellulose).
Step 2: Rayon.
Rayon is regenerated cellulose made by chemically treating natural cellulose and extruding it into fibers. It is a classic regenerated fiber.
Step 3: Acetate.
Acetate is also derived from cellulose, chemically modified by acetic acid. Thus, it is a regenerated fiber.
Step 4: Lyocell.
Lyocell is a modern regenerated fiber, produced by dissolving wood pulp cellulose in amine oxide solvent. It is eco-friendly and falls under regenerated fibers.
Step 5: Nylon.
Nylon, on the other hand, is a fully synthetic polyamide fiber made from petroleum-based chemicals. It is not derived from natural polymers and hence not regenerated.
Step 6: Conclusion.
Among the options, Nylon is not a regenerated fiber.
