The Science of Strength

First introduced in the 1930s, the term “nylon” refers to certain syntheticfibers produced entirely from chemical ingredients. The material then goes through a process known as polymerization. It is in this stage where nylon achieves its molecular strength. In particular, nylon 6,6 polymerization can achieve properties that make it superior to nylon 6 in many ways, including higher hydrogen bonding density and higher crystallization rate. These properties give nylon 6,6 resins and fibers advantages such as a higher melting point and greater strength.

Superior Durability

Nylon 6,6 Fiber

The nylon 6,6 flake is melted and extruded through spinnerets to become a long fiber, or filament. This type of fiber first became famous when it was used in women’s hosiery as a replacement to cotton and silk. The nylon hosiery was more durable and easier to care for. The fiber’s popularity quickly grew, finding uses in parachutes, tire cord, and many other applications that could benefit from its moisture and mildew resistance, high strength, high melting temperature and durability.

Nylon 6,6 Engineering Polymer

Due to its superior properties, nylon 6,6 is also widely used as an engineering polymer, finding applications in automotive, electronics, and the appliance and consumer markets. INVISTA’s Engineering Polymers business provides special product lines and technical services to support these applications.

Nylon 6,6 Production

INVISTA’s integrated nylon 6,6 production process involves several key steps, all occurring in-house to bring customers consistent products. In addition, INVISTA Performance Technologies offers licenses for some of its technologies to qualified producers in order to support the growing demand for nylon 6,6 in key applications around the world.
