Answer:
Statement 4. Synthetic fibres are biodegradable does not belong to a characteristic of synthetic fibres.
Explanation:
- Synthetic fibres are created in a lab with the aid of various chemicals. Examples: Nylon, Rayon, and Polyester
- These fibres are more durable and affordable.
- Synthetic fibre is cheaper than natural fibre.
- The strength of synthetic fibres exceeds that of natural fibre.
- Natural fibres aren't as strong as synthetic fibres.
- Synthetic fibres are easy to clean and preserve.
- They absorb very little. So they get stuck in the summer days during sweating. So these are not skin friendly.
- Also, they do not trap air pockets.
- These artificial or manmade fibres are petroleum-based products and are non-biodegradable.
- It is because they are nothing more than synthetic fibres. In reality, they are the chains of smaller polymers joined via polymerization.
- The biowastes are naturally broken down into simpler compounds by microorganisms like bacteria, but since synthetic fibres are chemically bound and not produced biologically, they cannot be broken down.
- Thus, they are biologically not degradable.
Hence, statement 4. is the correct answer.
