Definition of Nylon

Nylon 6, 6 is a polyamide from nylon class
Nylons come in many types, and the two most common for textiles and plastics industries are nylon 6 and nylon 6, 6 (Actually it is nylon 6 – 6)

More About Nylon

  • The polymer is made of hexamethylene diamine and adipic acid
  • It is made by condensation of hexamethylene diamine and adipic acid
  • Hexamethylene diamine and adipic acid are combined with water in a reactor
  • This produces nylon salt
  • The nylon salt is then sent into an evaporator where excess of water is removed
  • The nylon salt goes into a reaction vessel where a continuous polymerization process takes place
  • The chemical process produces nylon 6,6 which undergoes a spinning process, where the nylon 6,6 is extruded and sent through a spinneret
  • Nylon is then air cooled to form filaments
  • Nylon is a synthetic fabric made from petroleum products
  • Nylon was made as an alternative to silk, although it quickly became unavailable to civilian consumers, because it was used extensively during World War II
  • Nylon is valued for its light weight, incredible tensile strength, durability, and resistance to damage
  • Nylon takes dye easily, making the fabric available in a wide array of colors for consumers
  • Nylon is among the many polymer products in common daily use throughout the world
  • Nylon is the second most used fiber in the United States, since it is so versatile and relatively easy to make
  • Nylon has a very slow decay rate, which results in the accumulation of unwanted products in landfills around the world
  • Nylon is made through a chemical process called ring opening polymerisation, in which a molecule with a cyclic ring is opened and flattened
  • After nylon is extruded in a thread form, it is drawn or stretched after it cools to make long, even fibers
  • The strength of nylon comes from amide groups in its molecular chain

Uses of Nylon:

  • Nylon has a regular shape, which makes it well suited to creating fabrics designed to stand up to intense forces
  • In fact, it was the primary material used in parachutes and ropes during World War II for this reason
  • It is used in bullet proof vests and other hard wearing items
  • Nylon is very sensitive to heat and should be washed and dried on cool settings
  • The fabric can be hung dry, and it is favored by campers because it dries very quickly
  • Nylon is a flexible textile, hence it appears in a wide range of applications, from clothing to climbing equipment
  • It is used in stockings and toothbrush bristles, to make ropes, higher grade paper and military supplies
  • Nylon was also used to make guitar strings
