Question

A raw material used in making nylon is:
A. Ethylene
B. Adipic acid
C. Betadine
D. Acetylene

Answer 1

Hint: Nylon, any synthetic plastic substance consisting of high molecular weight polyamides and typically developed as a fibre, but not always. A research team led by an American chemist, Wallace H. Carothers, who works for E.I, invented nylons in the 1930s. Nemours du Pont & Company. Efficient development of a useful fibre through chemical synthesis from readily available compounds from air, water, and coal or petroleum stimulated expansion of polymer science, leading to a rapidly proliferating synthetic family. Nylon may be drawn, melted, or extruded from a melt or solution through spinnerets to form fibres, filaments, bristles, or sheets to be made into yarn, cloth, and cordage; and it may be shaped into moulded goods. It has a high wear resistance, heat resistance and chemical resistance.

Complete step-by-step answer:
To produce the filament known as nylon Diamine acid is pushed into a reaction with adipic acid. This type of polymer is commonly referred to as PA 6,6, and was the first type of polymer used in nylon fabric. PA 6,6 is a type of substance called a nylon salt and this crystallized material is then heated to form a molten material. This substance is then extruded through a spinneret, a tool that looks similar to a showerhead with hundreds of tiny holes in it. Nylon immediately hardens when extruded through the spinneret and the resulting fibres are then ready for loading onto bobbins. Such fibres are first stretched to maximize their strength and elasticity and are then woven in a process called "drawing" onto another spool. This process allows the polymer molecules to organize in a parallel pattern, and the resulting fibres are ready to be spun into garments or other types of fibres after the drawing process is complete. For some cases, nylon may be spun into fabrics alone but mixed textiles are typically blended with other fabrics. The colour which is desired for the final product is then coloured to produce.
Hence option B is the right answer.

Note: Adipic acid or hexane dioic acid is the organic compound with the formula. It is the most effective dicarboxylic acid from an industrial perspective: approximately 2.5 billion kilograms of this white crystalline powder are manufactured annually, primarily as a precursor for nylon production. Otherwise, adipic acid rarely occurs in nature but it is known as the E-number food additive E355 made.
