Which of the following is a plant fibre ?

Cotton is obtained from cotton plant. So it is a plant fibre.

Cotton is a plant fiber, derived from the cotton plant, specifically from the fibers around the seeds of the plant. It is one of the most commonly used natural fibers in the textile industry due to its softness, breathability, and absorbent properties. The cotton fibers are separated from the cotton boll (the seed pod) and spun into yarn, which can then be woven or knitted into fabrics. Cotton is used to make a variety of products, including clothing, bed linens, and medical supplies.

Let’s briefly discuss the other options:

• Wool is an animal fiber, obtained from the fleece of sheep and other animals like goats (for example, cashmere and mohair).
• Silk is also an animal fiber, produced by silkworms (caterpillars) to form their cocoons.
• Nylon is a synthetic fiber, meaning it is made from chemicals and is not derived from plants or animals.

Therefore, cotton is the only correct option that is a plant-based fiber.
