Nylon Fiber production

The first approach:

* combining molecules with an acid (COOH) group on each end are reacted with two chemicals that contain amine (NH2) groups on each end.

This process creates nylon 6,6, made of hexamethylene diamine with six carbon atoms and acidipic acid, as well as six carbon atoms.

The second approach:

* a compound has an acid at one end and an amine at the other and is polymerized to form a chain with repeating units of (-NH-[CH2]n-CO-)x.
* In other words, nylon 6 is made from a single six-carbon substance called caprolactam.
* In this equation, if n=5, then nylon 6 is the assigned name. (may also be referred to as polymer)

Nylon 6,6

* Pleats and creases can be heat-set at higher temperatures
* Nylon 6 is very easy to dye, but Nylon 6,6 is not

Nylon 6

* Better dye Affinity
* Softer Hand
