Imagine that if there is no zipper, an adult's clothes or a long-distance travel bag will have to be fitted with more than a dozen buttons, and it will take people a long time to operate. Zipper came out only a few decades ago, but it completely conquered the world. Now, who can say that he has never used a zipper?
Inventions, big or small, will have permanent vitality as long as they can bring convenience to people. The invention of zipper is an excellent proof.
1893, whitcomb Judson, an American engineer, used the principle of staggered concave and convex teeth to design a fast sliding lifting system and applied for a patent. This is the earliest zipper. This connection mode of zipper is different from the traditional connection mode. For many years, people have been used to tying clothes with buttons and shoes with belts. These connections are not completely closed, time-consuming and unstable. Zipper is undoubtedly a major breakthrough in the history of invention.
The original zipper is of poor quality, either easy to explode or unable to pull. 1905, the zipper making machine started to operate, but the product was still rough. 19 12, Swede Sen Debacker modified Judson's invention, and designed a set of female and male teeth on the back of zipper teeth, which made the zipper buckle firm and reliable, more exquisite and beautiful.
Sen Debacker zipped women's clothes, but they were afraid that once the zipper cracked, they would make a fool of themselves in public, so they couldn't promote it. At this time, a pilot was flying a plane for an air show, and a button rolled into the machine, causing a vicious accident in which the machine was destroyed and people were killed. Sen Debacker seized this opportunity, immediately contacted the army and suggested sewing a new military uniform with zipper. The trial proves that this kind of military uniform is very popular. Since then, more and more people have known about zippers.
193 1 year later, zippers began to be widely used all over the world. People sew it on wallets, handbags, backpacks and then on underwear. People find that zipper is really a very convenient thing to use. Since then, the varieties of zippers have emerged in an endless stream, and the materials used have increased from metal to plastic, and their uses have become more and more extensive. Zippers are not only used in clothing, but also in many other industries.
Zipper is just a small invention, but now the whole world can't live without it. Like buttons and ballpoint pens, zippers greatly improve people's quality of life.
