Zippers began in the mid-19th century. At that time people were particularly fond of boots, because these boots are very suitable for walking in the dirty streets, but there are more than 20 buttonholes on this kind of boots, people are particularly strenuous when wearing shoes off the shoes. By 1893, the American engineer Judson developed a "sliding type fastening device", also called "movable button", which was the initial prototype of the zipper. That year, the Judson founded the American Tyrone company.
Initially, the zipper is almost unattended, but why the zipper can spread all over the world, and in the end, thanks to the buttons.
Shortly after World War II, an air force air show was held in Paris. Unfortunately, there was a tragedy of plane crashes. The military is very nervous. It attaches great importance to this and conducted very detailed mechanical investigations. The result of the survey came out. Everyone was surprised to see that a button on the top of the pilot had fallen and it was just rolling into the engine of the plane, causing an accident.
This event gave the United States Tyron an excellent opportunity. They took the opportunity to sell the zipper to the French Ministry of Defence. Since then, the clothes on the pilot's body have no buttons, and instead they have been zippers. It is from this day that the zipper began to gain popularity, and Tyrone's business also followed.
