Which is correct about Rayon?

Options

A. Natural silk
B. Artificial slik
C. Natural plastic or rubber
D. Synthetic plastic

Answer

### Step-by-Step Solution:

1. **Understanding Rayon**:
- Rayon is a type of fiber that is known for its silk-like feel and appearance. It is important to recognize that rayon is not a natural fiber but a manmade one.

2. **Composition of Rayon**:
- Rayon is primarily made from purified cellulose. Cellulose is a natural polymer found in the cell walls of plants, and in the case of rayon, it is usually derived from wood pulp.

3. **Production Process**:
- The production of rayon involves several chemical processes:
- First, cellulose is extracted from wood pulp.
- The cellulose is then treated with sodium hydroxide (NaOH) to create a viscous solution.
- This viscous solution is referred to as "viscose," which is a syrup-like liquid.

4. **Spinning Process**:
- The viscose is then forced through a spinneret, which is a device with many tiny holes, to form long threads.
- These threads are then treated with diluted sulfuric acid (H2SO4), which helps in regenerating the cellulose and solidifying the fibers.

5. **Final Product**:
- After the spinning and treatment, the final product is rayon, which is often referred to as "artificial silk" due to its similar texture and appearance to natural silk.

6. **Conclusion**:
- Based on the above information, we can conclude that rayon is correctly classified as "artificial silk."

### Final Answer:
- Rayon is correctly identified as **artificial silk**.
