Group of synthetic fibers are :

Question

Accepted Answer

Option 1, which includes Orlon, Nylon, and Decron, is the correct answer because these are all synthetic fibers. Synthetic fibers are man-made fibers produced from chemical substances, typically derived from petroleum products. They are created through a process called polymerization, where small molecules are chemically bonded to form long chains.

1. **Orlon**: This is a trademarked name for a type of acrylic fiber. Acrylic fibers are synthetic fibers made from a polymer called polyacrylonitrile. Orlon is known for its wool-like feel and is often used in clothing and home furnishings.

2. **Nylon**: Nylon is a well-known synthetic fiber made from polyamides. It was the first synthetic fiber to be commercially successful and is widely used in textiles, including clothing, ropes, and even toothbrush bristles, due to its strength and elasticity.

3. **Decron**: This is a less common name but is often associated with polyester fibers. Polyester is another synthetic fiber made from polyethylene terephthalate (PET). It is known for its durability, resistance to stretching and shrinking, and quick-drying properties.

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

- **Option 2: Cotton, Rayon, Silk**
  - **Cotton** is a natural fiber obtained from the cotton plant. It is not synthetic.
  - **Rayon** is a semi-synthetic fiber made from regenerated cellulose, often derived from wood pulp. While it is man-made, it is not considered a fully synthetic fiber like those in Option 1.
  - **Silk** is a natural protein fiber produced by silkworms. It is not synthetic.

- **Option 3: Linen, Silk, Wool**
  - **Linen** is a natural fiber made from the flax plant. It is not synthetic.
  - **Silk** is a natural fiber produced by silkworms.
  - **Wool** is a natural fiber obtained from sheep and other animals. It is not synthetic.

- **Option 4: Linen, Polyester, Silk**
  - **Linen** is a natural fiber from the flax plant.
  - **Polyester** is a synthetic fiber, but since the other two fibers in this option are natural, this option is not a group of synthetic fibers.
  - **Silk** is a natural fiber produced by silkworms.

In conclusion, Option 1 is the only option that consists entirely of synthetic fibers, making it the correct answer.
