Just like Vivaldi was inspired by nature to compose his Four Seasons concertos, the inventor of Velcro was also inspired by nature. Specifically, by burrs.
Swiss engineer George de Mestral first conceptualized Velcro in 1941 after examining the burrs that stuck to his clothes, hair and dog鈥檚 fur, something we now call biomimicry- taking inspiration from nature to innovate human design. He sought to mimic the hook-and-loop interaction with woven materials but was not taken seriously by those in the weaving industry. It wasn鈥檛 until Mestral turned to the newly invented synthetic fabric nylon and discovered how to mechanize Velcro鈥檚 creation (this took about 10 years), that his design began to spread throughout Europe.
It was marketed as a 鈥渮ipperless zipper鈥 but failed to gain mainstream popularity due to its less than ideal appearance. NASA鈥檚 use of Velcro in space suit designs prompted skiers to begin to utilize it, followed by Scuba divers and children鈥檚 clothing makers.
A slight aside- it turns out that NASA research or adoption is responsible for many of the innovations we use on a daily basis! Quite a few major technologies, like enriched baby food, cordless vacuums, LEDs and firefighter equipment were developed thanks to NASA. Read more about that here-
Today Velcro is used everywhere from in shoes to the International Space Station. It鈥檚 so common that I鈥檓 willing to bet there鈥檚 some within a few metres of you at this very moment. There a few reasons it is so popular as a fastener: It is usable thousands of times (tens of thousands if it鈥檚 made of stronger materials like Teflon), it鈥檚 cheap to manufacture, its resistant to degradation in wet conditions (although it will absorb water and grow mold) and maybe most importantly, it鈥檚 really strong! Velcro (the company) provides weight ratings up to 120 kg for some of its products.
