Which of the following is not a property of natural fibres?

• A. Always waterproof.
• B. Durable.
• C. Breathable.
• D. Easy to maintain.

Answer: (A)

Natural fibres are typically porous and hydrophilic, meaning they readily absorb moisture. This moisture-absorbing nature is what gives natural fabrics their breathability—the ability for air and water vapor to pass through, keeping you comfortable. Because of that porous structure, they don’t act as a barrier to water, so they aren’t inherently waterproof. Waterproofing usually requires a non-porous barrier or special finishes, often found with synthetic fabrics or heavily treated materials. So the statement that natural fibres are always waterproof isn’t accurate; their strength lies in breathability and moisture management, not in repelling all water.
