What is the property of cotton?
Cotton fibers are natural hollow fibers; they are soft, cool, known as breathable fibers and absorbent. Cotton fibers can hold water 24–27 times their own weight. They are strong, dye absorbent and can stand up against abrasion wear and high temperature.
What are the physical properties of cotton?

- Color: The color of cotton fibre could be white, creamy white, bluish white, yellowish white or grey.
- Tensile Strength: Cotton is moderately strong fibre; tenacity is 26.5-44.1 cN/tex and tensile strength 2800-8400 Kg/cm^2.
- Elongation at break: Cotton does not stress easily.

What are the two properties of cotton?
Write two characteristic properties of cotton
- Color: Its colour is from white, creamy white, bluish white to yellowish white or grey.
- Tensile Strength: It is moderately strong fibre and good tensile strength which is greatly affected by moisture, the wet strength is higher than dry strength.
What are the 5 natural fibers?
Common natural fibers sourced from the plant kingdom include cotton, flax, hemp, bamboo, sisal, and jute. Their main component is cellulose. From animals, we get popular fibers like wool, silk, angora, and mohair.
Which is the strongest Fibre?
With so many natural fibres known for its tensile strength, silk is the toughest natural fibre found in our nature. One of the natural fibres known to man is its woven fabrics from the silkworm’s or caterpillar’s cocoon. Other animals, like spiders, also produce this fibre.
What is the weakest natural fiber?
Silk is the strongest of all the natural fibres and Wool is the weakest of all natural fibres.
Is the strongest natural Fibre answer?
Answer: Silk is the strongest natural fiber.
Is cotton a natural Fibre?
Cotton: It’s almost pure cellulose, with softness and breathability that have made it the world’s most popular natural fibre. Fibre length varies from 10 to 65 mm, and diameter from 11 to 22 microns.

Is cotton a strong fabric?
Cotton has a high tensile strength, making it strong, durable and less likely to rip or tear. It is 30 percent stronger when wet, withstanding many washings in hot water.
What’s bad about cotton?
As well as being a thirsty crop, cotton cultivation currently uses lots of chemicals – 4 per cent of all world pesticides and 10 per cent of insecticides are used in cotton-growing6. These inputs can pollute local eco-systems and drinking water supplies.
What are disadvantages of cotton?
Disadvantages
- Not a very strong fabric.
- Absorbent – heavy and takes a long time to dry, also stains easily.
- Poor elasticity so creases badly.
- Shrinks badly.
- Highly flammable and burns quickly.
- Attacked by mildew if left damp.
How can you tell if fabric is 100% cotton without burning?
You can test fabric for 100% cotton using the burn test. Take a few fibers and hold them against a flame. 100% cotton will not curl from the heat. It smells like burning paper and leaves grayish ash without signs of melting.
What is the burn test for cotton?
Place a piece of the fabric in your fireproof container and ignite one corner. Pay attention to the odor of the smoke. Cotton smells like burning paper and has an afterglow at the end of the burn. An odor similar to burning hair or feathers indicates wool or silk fibers, but silk doesn’t always burn as easily as wool.
