Answer :

Who invented Velcro?

The correct answer is option 'B', George Mestral.

Explanation:

Introduction:
- Velcro is a hook-and-loop fastening system that is widely used in various applications, such as clothing, shoes, and even space exploration.
- It consists of two components: a strip of fabric with tiny hooks and another strip with small loops that interlock when pressed together.

George Mestral:
- George de Mestral, a Swiss engineer, is credited with inventing Velcro in the 1940s.
- The idea for Velcro came to him after a hunting trip when he noticed burrs sticking to his clothes and his dog's fur.
- He examined the burrs under a microscope and discovered that they had tiny hooks that caught onto the loops in his fabric.
- This observation inspired him to develop a similar fastening system.

Development of Velcro:
- Mestral spent several years experimenting with different materials and designs to create a functional hook-and-loop fastener.
- He eventually settled on nylon as the ideal material for the hooks and loops due to its durability and flexibility.
- Mestral patented his invention in 1955 and named it "Velcro," which is a combination of the French words "velours" (velvet) and "crochet" (hook).

Applications and Popularity:
- Velcro gained popularity quickly and found a wide range of applications in various industries.
- It revolutionized the clothing industry by providing a convenient alternative to buttons and zippers.
- It also became widely used in sports gear, medical devices, automotive interiors, and many other products.
- The space industry also embraced Velcro due to its ability to secure objects in zero-gravity environments.

Legacy of George Mestral:
- George Mestral's invention of Velcro revolutionized the fastening industry and continues to be widely used today.
- His innovative thinking and persistence in developing Velcro have left a lasting impact on the world.
- Mestral's work serves as an inspiration to aspiring inventors and engineers.

In conclusion, George Mestral, a Swiss engineer, is credited with inventing Velcro in the 1940s. His observation of burrs sticking to fabric led to the development of the hook-and-loop fastening system that revolutionized various industries. Velcro continues to be a widely used and valuable invention today.
