_____ fiber is known as Artificial silk.

Question

Accepted Answer

Rayon is known as artificial silk because it was developed to mimic the properties of natural silk. It is a semi-synthetic fiber made from cellulose, which is derived from wood pulp. The process of creating rayon involves dissolving cellulose in chemicals and then extruding it through fine holes to form fibers. These fibers are then spun into yarns and woven into fabrics. Rayon has a smooth, silky texture and a sheen that closely resembles natural silk, making it a popular and cost-effective alternative.

Now, let's examine why the other options are incorrect:

2. Nylon: Nylon is a synthetic fiber made from petrochemicals. It was developed as a substitute for silk, especially during World War II, but it is not referred to as artificial silk. Nylon is known for its strength, elasticity, and resistance to abrasion, which are different characteristics compared to the softness and sheen of silk.

3. Linen: Linen is a natural fiber made from the flax plant. It is known for its strength, absorbency, and coolness in hot weather. Linen has a distinct texture and appearance that is quite different from silk, and it is not considered an artificial silk.

4. Polyester: Polyester is a synthetic fiber made from petrochemicals. It is known for its durability, resistance to wrinkles, and ability to hold its shape. While polyester can be made to mimic the appearance of silk, it is not specifically known as artificial silk. Its properties and feel are different from those of natural silk.

In conclusion, rayon is the correct answer because it was specifically developed to replicate the properties of silk, earning it the name "artificial silk." The other options, while they have their own unique characteristics and uses, do not share this specific association with silk.
