Question

Which of the following is a fibre?
a. Nylon
b. Neoprene
c. PVC

Answer 1

Hint: Fibres are the long strands of molecules interwoven in such a way so as to to form a linear and string like structure. They may either be natural or manmade. The natural fibre is a composite material comprising cellulose, pectin, hemicelluloses, lignin, or waxes. Man Made or synthetic fibres are derived from the chemical resources.

Complete answer
Let us discuss in brief each material mentioned in the options:
a. Nylon: Nylon, generally known as polyamide, is also a synthetic thermoplastic material that can be processed into films, fibers or shapes. It is a condensation polymer or copolymer consisting of amide linkages formed by the reaction of difunctional monomers consisting of equal parts of carboxylic acid and amines. Nylon 6, Nylon 66, Nylon 510 are few types of Nylon. Synthesis of Nylon 6 is shown below in which ring opening of caprolactam takes place in the first stage (I) followed by condensation polymerization (II).

b. Neoprene: Neoprene is a family of synthetic rubbers that is formed through a chemical reaction which utilises chloroprene, and as a resultant, polychloroprene chips are left behind. It is generally prepared through the free radical polymerization of chloroprene. Thus, it is also known as polychloroprene. It is employed as an insulator, for the manufacturing of hoses, belts, gaskets, etc.

c. PVC: PVC known as polyvinyl chloride is a solid synthetic plastic material or polymer made from the polymerization of vinyl chloride. PVC is generally used in the manufacturing of pipes, hoses, polyvinyl flooring and siding, cable coatings, plumbing, medical devices, and automotive parts.

Hence, the correct answer is Nylon.

Note:
Nylon fibres are exceptionally strong as well as elastic. They are even stronger than polyester fibres. The fibres possess excellent abrasion resistance, toughness, and are easy to dye and wash in a wide range of colours.
