How is Nylon made

The idea for Nylon was first put forward by Charles Stine the director of Du Pont's Chemical [ie.,central research] Department it was through Wallace Carothers who also worked at DuPont that created the first nylon material on 28 February 1935

Nylon is made by condensation copolymers formed by reacting equal parts of a Diamine and a Dicarboxylic acid as this video below shows here.

The semi-liquid material is then forced into a spinneret, which is used to separate the nylon into thin strands.

As the Nylon is exposed to the air it causes the strands to harden immediately and once they are hard, they can be wound onto bobbins. The fibres are stretched to create strength and elasticity. The filaments are unwound and then rewound onto another, smaller spool. This process is called drawing and is used to align the molecules into a parallel structure.
After the nylon has been wound onto the smaller spool, it is ready for use. Nylon products are created by weaving the filaments together. The tighter the weave, the more strength the fabric will have.
