Coil zippers are made of polyester coil and are thus also termed polyester zippers. Nylon was formerly used to make them, and though only polyester is used now, [citation needed] the type is still also termed a nylon zipper.

In 1960 the Talon Zephyr, a zipper with a nylon filament coil construction, was introduced. It was half as wide as their smallest metal fastener, and was more flexible. By 1962 the Zephyr represented one-third of Talon’s 500 million unit sales.
A major technological change came in 1950, when the company purchased a chain machine from the U.S. that allowed the automation of the zipper making process. Previously, YKK zippers were made by hand, and hence had an inferior quality compared to automated zippers from abroad. In March 1951, YKK relocated its headquarters to Chūō, Tokyo.

Ripstop is a woven fabric, often made of nylon, using a reinforcing technique that makes it more resistant to tearing and wear. During weaving, stronger (and often thicker) reinforcement yarns are interwoven at regular intervals in a crosshatch pattern. The intervals are typically 5 to 8 millimeters (0.2 to 0.3 in).
