Question

Viscose Rayon is a _______ fiber.

• A. Protein
• B. Polyamide
• C. Regenerated Cellulosic
• D. Elastomeric

Hint:

Understanding the manufacturing processes and sources of different fibers can help in accurately identifying their types.

Answer 1

The Correct Option is C

Step 1: Concept
Fibers can be classified into different types based on their source, manufacturing process, and chemical composition. Viscose Rayon is a specific type of fiber that falls under the category of regenerated cellulosic fibers.

Step 2: Meaning
Regenerated cellulosic fibers are produced by dissolving cellulose from natural sources such as wood pulp or cotton, then reconstituting it into fibers through a chemical process. This method allows for the creation of synthetic-like properties while maintaining some characteristics of natural fibers.

Step 3: Analysis
Viscose Rayon is derived from cellulose, which is obtained from plant materials like wood pulp. The production process involves dissolving the cellulose in a caustic solution to form a viscous liquid (hence "viscose"), which is then extruded through spinnerets into a coagulating bath where it solidifies and regenerates back into fiber form. This process makes Viscose Rayon a regenerated cellulosic fiber. Option A, Protein fibers, include materials like silk or wool, which are derived from animal sources. Option B, Polyamide fibers, such as nylon, are synthetic polymers made through chemical synthesis involving amide bonds. Option D, Elastomeric fibers, typically refer to elastic materials that can stretch significantly and return to their original shape, often including spandex or elastane.

Step 4: Conclusion
Given the process of production and composition, Viscose Rayon is correctly classified as a regenerated cellulosic fiber. Final Answer: (C)
