how does the 2 sides of a well-crow stick?

Answer 1

It's officially called "hook & loop fastener". And that's how it works. One side has tiny hooks, like fishing hooks, and the other has little loops. Pust them together and the hooks grab the loops.

Answer 2

I'm by no means an expert on Velcro, but from what I gather it's a very simple idea. Basically, Velcro relies on two different types of material that hold together. One half had thousands of tiny hooks on it, and the other has a softer, fibrous and almost fluffy texture. When the pieces of material are pressed together, the tiny hooks get entagled in the fibrous material, causing it to grip. When pulled apart, you simply force the hooks away from the other material, which is normally accompanied by the tearing sound associated with Velcro. Each time you stick the two halves together, and tear them apart, you do slowly cause wear, either by breaking the hooks, or wearing out the fibrous material. After time, on heavily used Velcro, this can sometimes lead to it not holding together as well as it did when new.

Just as an aside, Velcro is actually a trademark - this type of fastening system is manufactured by other companies, and not called Velcro. However, much like the trademark Hoover is used to describe a vacuum cleaner, Velcro is typically used to describe this type of fastener.

Answer 3

Don't believe any of them, velcro is based on envy. You use one side and the other side wants to do that as well. That's why they both stick and come off at the same time..
