Polyamides or Nylon is the major engineering and high performance thermoplastics class because of its good balance of properties. Polyamides contain repeating amide linkages i.e. –CO-NH–. It is formed by condensing identical units, copolymers for different units. Polyamides (or Nylon) are made from polycondensation of diacid with a diamine or by ring-opening polymerization of lactams with

Nylon is one the first man-made chemicals, and dates back to World War II. The synthetic has extensive applications, with specific uses in clothing and other protective material. Making nylon is as a simple process you can undertake yourself.
Get PriceNylon is made in a process known as "melt spinning." First, a syrupy polymer solution is produced and then extruded through a spinneret. As the nylon strings emerge, they are cooled by air and stretched over rollers to stabilize the molecular chains and strengthen the fibers. The yarn is then wound on spools.
