Description
Nylon 6 is made by polymerizing caprolactam under pressure. Nylon 6 was first sold as Perlon L in 1939 by I.G.Farbenindustrie. It was produced during W.W.II for parachutes. Nylon 6 is very similar to nylon 6,6 except that it has a greater affinity for dyes and has a lower melting point. Its thermoplastic fibers are strong, tough, elastic and have high gloss. They are extruded through a spinneret with a circular cross section. Nylon monofilaments are used for brushes, surgical sutures, tennis strings, and fishing lines. Nylon 6 is also used for heat-seal films because it has low water vapor transmission rates. Cellular nylon foam is made from nylon 6 for lightweight buoys and flotation products.

Other Properties
Resistant to alkalis and most organic solvents. Degraded by concentrated acids and phenol. Burns with yellow-orange flame and blue smoke; smells of burnt horn. Fiber is smooth. Cross section is circular. Tenacity = 3.8-8.3 g/denier (dry); 3.5-7.1 (wet); Elongation = 16-50% (dry); 19-55 % (wet); Moisture regain = 3.5-5.0% (dry)
