How is nylon prepared?

Answer 1

Nylon is one of the most important chemical discoveries of the 20th century .It is one of the toughest , strongest and most elastic substances we have today . It is a synthetic plastic material which is made from chemicals derived from coal, water, air, petroleum, agricultural by-products and natural gas .

It was first developed by a research team headed by a U.S. chemist Wallace H.Corothers working in E.l. Dupant De Nemours & Co. He began experimenting with it in the 1920s. In 1935, he produced the first piece of nylon. It was converted into cloth in 1937.

Nylon is made from two chemical compounds : Hexamethylenediamine consists of carbon, nitrogen and hydrogen. Adipic acid contains carbon, hydrogen and oxygen. Each of these substances contains six carbon atoms and the Nylon-6, 6. Manufacturers combine the two compounds to form a substance called nylon salt. A solution of nylon salt is placed in an autoclave (a heating device). The autoclave heats the solution under pressure. Water is removed and the small molecules in the compound , combine to form large molecules. This process is called polymerisation.

When caprolactam is used as the starting material, Nylon -6, 6 is obtained. It has been so named because it has six carbon atoms in the basic unit. It is comparatively a recent development.

Answer 2

Nylon is prepared through a process called polymerization, where molecules called monomers are chemically bonded together to form long chains. The most common method involves reacting diamines and diacids in a condensation reaction to form the nylon polymer. The resulting nylon can be extruded into fibers, molded into shapes, or spun into films.

Answer 3

Nylon fabric is a poly amide made from petroleum.

Nylon was the first synthetic fibre produced in 1935.

Answer 4

it is put into a spinneret then small bobble appesr

Answer 5

it is obtained from petroleum

Answer 6

it is made on a farm
