Nylon fiber

Jump to: navigation, search


A generic name for any manufactured fiber in which the fiber-forming substance is any long chain synthetic polyamide having recurring amide groups (-NH-CO) as an integral part of the polymer chain (Federal Trade Commission definition). Nylon 6,6 was first made in the early 1930s by W. H.Carothers as a textile fiber called fiber #66; the name nylon was coined in 1938 by DuPont. By 1939, nylon 6,6 and nylon 6 were being commercially produced in the US and Germany, respectively. Nylon 6,6 and nylon 6 are still the most common nylons used in fibers. All nylons are strong, tough, elastic and have high gloss. They are extruded through a spinneret and have a circular cross section. Nylon monofilaments are used for brushes, surgical sutures, tennis strings and fishing lines. Titanium dioxide may be added to the surface of nylon fibers to reduce luster. Nylon fibers are used for clothing, undergarments, linings, carpets, tire cords, conveyor belts, parachutes, hosiery and brushes. Nylon fibers have excellent dyeability and are twice as durable as cotton.

Other Properties

Resistant to alkalis and insoluble in most organic solvents. Soluble in hot phenols, cresols and mineral acids. Moisture regain = 4.2-5.0%.

When placed in a continuous flame, nylon melts first, then ignites and burns rapidly. It smells like burnt plastic.

Melting Point 250
Density 1.14
Refractive Index 1.53

Hazards and Safety

Potential degradation products are carbon monoxide and cyanogen. Degraded by sunlight. Flame resistant. Resistant to insects and microorganisms.
