Yes, the hook and loop structure of a velcro fastener is a solid structure.
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.
Hydrate: a solid compound that contains water molecules as a part of the solid crystalline structure
A solid material with no crystal structure is called amorphous.
The crystalline structure of the solid most determine the entropy of a solid.
Velcro is a composite material, not a compound.
Velcro is not grosgrain. Velcro is a form of fastener, grosgrain isn't
Velcro and buttons
Velcro is the Velcro Industries product name for hook and loop fastener, typically manufactured as tape, either adhesive backed or non-adhesive backed.
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.
Velcro is actually a brand name of a hook and loop fastener. It was inspired by the hooks of grass burrs that attach to clothing and fur. It is made to fasten things together.
A velcro strap is a creative, flexible, and easily manipulated fastener. It can be used in many different situation where you would need an easily adjustable fastener and don't require very high strain resistance. It is commonly used on shoes, carrying cases, and pants.
Velcro and buttons
Velcro is the first commercially marketed fabric hook-and-loop fastener. It was invented in 1948 by a Swiss engineer named George de Mestral. Velcro is used for many different things, such as shoes, chessboards, etc.
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.
George de Mestral was an electrical engineer from Switzerland. He is credited with the invention of the hook and loop fastener, better known as Velcro.
Velcro was designed for and originally used as a fastener for clothing. However, it was slow to be adopted by the fashion industry due to the way the original design looked when incorporated into clothing. It was not until many years later that the manufacturing process was perfected and Velcro's use became widespread in a wide variety of applications.
The inspiration for Velcro came about when Swiss engineer George deMestral took a closer look at burs that stick so well to things, like dog fur and your pair of socks. He recreated what he discovered into a new type of fastener.
