Velcro consists of two fabric strips, one with a dense array of hooks and the other with loops, that attach when pressed together. Zippers, on the other hand, have interlocking metal or plastic teeth that can be opened or closed by pulling a slider. Velcro is typically used for temporary closures and detachable items, while zippers are more commonly used for securing openings in garments and bags.
Tires on the road: Friction between tires and the road surface provides the necessary traction for vehicles to accelerate, decelerate, and turn safely. Zipper: The interlocking teeth of a zipper create friction that keeps it closed, allowing for easy opening and closing of clothing items. Velcro: The hook-and-loop system of Velcro fasteners uses friction to secure items together, offering a reusable and convenient fastening solution.
The success of the zipper led to the conception and development of many other innovations. Velcro, the plastic zipper, and resealable plastic bags all have origins that link directly back to the hookless fastener.
Velcro is a biological mimic of nature's Cocleburs. Just as the barbed wire!
