Question

It is an example of natural fibre
(A) Cotton
(B) Polyester
(C) Nylon

Answer 1

Hint : Fibre is a material that is much longer than it is wide, whether it be natural or man-made. Fibers are frequently used to create other materials. Fibers, such as carbon fibre and ultra-high-molecular-weight polyethylene, are frequently used in the strongest engineering materials. Synthetic fibres can typically be manufactured more cheaply and in greater quantities than natural fibres, although natural fibres have several advantages over synthetic fibres in clothing, such as comfort.

Complete Step By Step Answer:
Natural fibres, which include those generated by plants, animals, and geological processes, form or appear in the fibre form. They can be categorised based on where they came from:
Cotton, hemp, jute, flax, abaca, pia, ramie, sisal, bagasse, and banana are examples of vegetable fibres based on cellulose arrangements, frequently with lignin. Plant fibres are used to make paper and textiles (clothing), and dietary fibre is an essential part of human nutrition.
Wood fibre, as opposed to vegetable fibre, comes from trees. Groundwood, lacebark, thermomechanical pulp (TMP), and bleached or unbleached kraft or sulfite pulps are some of the options. The terms kraft and sulfite relate to the pulping processes that are used to remove the lignin that binds the original wood structure, allowing the fibres to be utilised in paper and engineered wood products like fibreboard.
Animal fibres are mostly made up of certain proteins. Silkworm silk, spider silk, sinew, catgut, wool, sea silk, and hair like cashmere, mohair, and angora, as well as fur like sheepskin, rabbit, mink, fox, and beaver, are examples.
Asbestos fibres are a kind of mineral fibre. Asbestos is the only long mineral fibre found in nature. Amosite, crocidolite, tremolite, anthophyllite, and actinolite are among the six minerals classed as "asbestos," including serpentine chrysotile and amphibole amosite, crocidolite, tremolite, anthophyllite, and actinolite. Wollastonite and palygorskite are short, fiber-like minerals.
Biological fibres, also known as fibrous proteins or protein filaments, are made up mostly of physiologically relevant and physiologically highly essential proteins, in which mutations or other genetic flaws can cause serious illnesses. Collagen proteins, tendons, muscle proteins like actin, and cell proteins are all examples.
Hence option A is correct.

Note :
In contrast to completely synthetic fibres such as nylon (polyamide) or dacron (polyester), which chemists synthesise from low-molecular weight compounds through polymerization (chain-building) reactions, semi-synthetic fibres are made from raw materials with naturally long-chain polymer structures and are only modified and partially degraded by chemical processes. The cellulose regenerated fibre rayon is the first semi-synthetic fibre. Coir regenerated fibres make up the majority of semi-synthetic fibres.
