  6. Origin

  7. Despite the origin of the zipper was to close sacks of mail promptly instead of using buttons or bands to close them, the zipper was used for military boots too but the revolution of the zipper was its application to clothing. • With the zipper you solved the problem of being wasting time closing and opening everything with buttons or bands. But it had an inconvenient. Because of the material they were made of, you had to unpick the zipper so the metal not rust through. This problem was solved by changing the materials they were made of (using stainless materials or plastic instead of stain materials). • We have to remark that the most important application of the zipper was to clothing. In 1930 the zippers appeared in children clothing to help them to get dressed by themselves and promptly. The zipper began to have more importance in 1937 through French designers who used them in trousers for men. In 1940 the 85% of the trousers had zippers instead of buttons and the new closing system started to be a modernity symbol. “No more buttons, bands or buckles” said The New York World in 1917. The next big boost of the zipper came when them started to be used in jackets and when you could opened the zippers by the two sides. In 1941 George de Mestral invented the Velcro system but nowadays, the button, the zipper, and Velcro are still used in different areas of our lifes but anyone has win others because all of them are necessary.
