The word 'velcro' comes form the two French words "velours" or 'velvet' and "crochet", or 'hook'. Thus the side that hooks is the one that is rough rather than velvet to the touch.
The loop side of Velcro is smooth and soft. The hook side of Velcro is rough and scratchy. The hooks catch on the loops to stick them together.
It is called the "loop" side.
Velcro sticks together by one side having small "loops" and the other side having small hooks.
Velcro works when one side of the fastener---a side full of tiny "hooks"---attaches to the other side of the fastener---a side full of tiny "loops." The hooks lock into the loops, and when they are pulled apart, they make that distinctive sound.
look at both pieces. you have a rough side and a softer side. the rougher side, if you look close, has little hooks that attach to the softer side. when you pull it apart the hooks are ripped apart, tis would be why velcro doesn't last forever.
Velcro is used to attach things together. Velcro has one strip that has a furry or loop style side and another side that has hooks. These two pieces adhere to one another to make things stick together.
Velcro is used instead of zips ect. It has hooks so that they can cling on.
The "fluffy" side of velcro will retain some water and also the taped backing on which the "hooks" are mounted will also. Ive yet to discover if velcro still works when its wet though. (probably does, because wet suits have velcro)
Velcro is made of tiny hooks and loops.
Velcro is not a chemical structure, it is a physical structure of semirigid hooks and fiber loops. The hooks and loops are typically made of nylon for strength, but could be made of other polymers.
velcro goes back to its normar size. velcro is hooks can break if there is too much wight.
it is made out of plastic hooks and loops, and nylon and polyester.
