Under The Microscope: Velcro
Ada McVean B.Sc.
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’s 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’t until Mestral
turned to the newly invented synthetic fabric nylon and discovered how to
mechanize Velcro’s creation (this took about 10 years), that his design began
to spread throughout Europe.
It was marketed as a
“zipperless zipper” but failed to gain mainstream popularity due to its less
than ideal appearance.
NASA’s use of Velcro in
space suit designs prompted skiers to begin to utilize it, followed by Scuba
divers and children’s 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.

Today Velcro is used
everywhere from in shoes to the International Space Station.
It’s so common that I’m
willing to bet there’s 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’s made of stronger materials like Teflon), it’s cheap to manufacture, its
resistant to degradation in wet conditions (although it will absorb water and
grow mold) and maybe most importantly, it’s really strong!
Velcro (the company)
provides weight ratings up to 120 kg for some of its products.
