Question

Cotton clothes are made from:
(A) Machine.
(B) Plant Fibres.
(C) Animal Fibres.
(D) None of these.

Answer 1

Hint : We know that the fibres are filaments or threads from which mineral substances, vegetable tissues or textiles can be formed. In textile, a fibre can be defined to be a product that is capable of being woven or made into a fabric.

Complete Step By Step Answer:
Natural fibres are those fibres which are made of plant and animal based fibres. They are biodegradable as they can be eventually broken down by microorganisms. For example, cotton, wool, silk. Since cotton and jute are both made of plant fibre cellulose, they are both biodegradable. On the other hand, synthetic fibres or man-made fibres are not found naturally on the earth. They are produced entirely from chemicals to create fabrics. As a result, they are much stronger than natural fibres and do not degrade in the soil. Thus, they are non-biodegradable. For example, nylon, polyester etc. Nylon is a synthetic fibre. It is a polyamide and has high tensile strength, is tough and elastic and abrasion resistant.
Nylon fibres do not rot like cotton fibres. Thus, they are stronger than the natural fibres and hence are not biodegradable. Terry Cotton fibres are man-made fibres produced by weaving in looping patterns. We know that natural fibers are hair like raw material which is directly derived from vegetable, an animal or mineral source and is turned into non-woven fabrics like felt or paper or, after spinning into yarns, into woven cloth. We can further define a natural fiber as a collection of cells where the diameter is negligible when compared with the length. Some of the examples of natural fibers are wood, grains, straw, jute, linen, wool and cotton.
Therefore, the correct answer is option B.

Note :
Remember that the synthetic fibres have more durability and involve cheaper manufacturing than natural fibres, their demands have increased. But in some cases, natural fibres are better than synthetic ones. For example, cotton fibres are soft and breathable fabric but polyester fibres contain man-made toxins and are uncomfortable for the skin and so cotton will be more preferable. Both have their own advantages and disadvantages.
