The History and Evolution of Zippers: From Clasp Lockers to Global Dominance

TLDR The invention of zippers, originally called clasp lockers, required the development of various technologies and went through several iterations before becoming the popular fastening device we know today. From Whitcomb Judson's early designs to Gideon Sunback's improvements and the rise of YKK, the dominant zipper manufacturer, this episode explores the fascinating history and ongoing innovations in zipper design.

Timestamped Summary

00:00 The invention and use of zippers, which required the development of several other technologies, is explored in this episode.
01:22 The zipper was not invented to solve a problem, as there were already fastening devices for clothing, but it couldn't have been invented any earlier than it was due to the state of technology at the time.
02:42 Whitcomb Judson is credited with inventing the zipper, which was originally called the clasp locker and used a hook and eye system, but he also submitted a patent for a device that was much closer to the modern zipper.
04:00 Whitcomb Judson created the Universal Fastener Company, the first company dedicated to producing zippers, but it wasn't until Gideon Sunback, an employee of the Talon Company, refined the product and improved its manufacturing process that the zipper really took off.
05:20 Zipper usage on clothing didn't become popular until 1937 when French fashion designers started using them on men's trousers, and the largest zipper manufacturer at the time, Talon Company, had high prices and lacked innovation.
06:40 YKK, which stands for Yoshida Kogyo Kabushiki Gaisha, became the dominant zipper manufacturer, surpassing Talon, by investing in their own manufacturing equipment, innovating in manufacturing processes and design, and opening manufacturing facilities around the world, including the United States, ultimately becoming the global leader in zippers by the 1980s.
08:02 Zippers come in a wide variety of sizes, colors, and materials, and there are ongoing innovations in zipper design, such as a magnetized zipper that can be easily operated with one hand.
