Hook and Loop fasteners have become day by day features of both industry and households. Yet, they have one difficulty: they are too feeble for many applications. Hook and Loop fasteners made of coil steel have now been developed at the association of Metal Forming and Casting of the Technical Universities Muenchen. These fasteners are resistant to chemicals and can hold out a tensile load of up to 35 tones per square meter at temperatures as high as 800°C.
Over 60 years ago when the Swiss engineer and inventor George de Mestral was thoroughly removing burrs from his dog’s coat after a hunting pleasure trip, he stumbled on a creative idea. Based on the reproduction he had practical in nature, he made a fastener from frequent small Hook and Loop, which he afterward named “Hook Loop ." “The matchless advantage of a Hook and Loop Fastener is that it is easy to close and open again,” explains Josef Mair, a scientist from the Institute of Metal Forming and Casting (utg) at the TU Muenchen. Because of this, the Hook and Loop principle is put to a very wide range of uses, e.g. as an alternative to shoe laces, to secure checkup bandages and prostheses, and for the cable boots used in automotive and aviation electronics.
Unfortunately, normal synthetic Hook and Loop fasteners are not very challenging to heat and aggressive chemicals. “Things can get very hot, for example, in the automotive sector. A car parked in direct sunshine can reach temperatures of 80 °C, and temperatures of several hundred degrees centigrade can arise around the exhaust manifold. forceful disinfectants are used for cleaning purposes in hospitals, and traditional Hook and Loop fasteners are too weak for use in the construction of building façades,” explains Mair.
Who Invented Hook Loop :
In 1948, A Swiss mountaineer named George de Mestral was going from side to side the woods and was very irritated by the burs that clung to his dress. As picking them off, he realized that it may be probable to use this law to make a fastener to compete with the zipper. Everybody laughed at him, except for a weaver at a textile plant in France. Collectively, they considered what they called "locking tape". It was prepared from cotton. The main difficulty that they faced was group producing it. Complicated equipment was needed.
Next problem - the name. by hook or by crook 'hookless fastener' or 'locking tape' did not seem right. If I were there, I would have recommended a name like 'man made bur tape that sticks to the other side and fastens things together' - a much catchier name. He liked the echo of "vel" from velvet and "cro" from the French word crochet (meaning hook). And the name Hook Loop fixed, just like those irritating burs. (their legal division wants you to know that Hook Loopis a trademarked name of Hook Loop USA and not a standard name - in other words, they don't create the Hook and Loop fasteners - they make Hook Loop. By the end of the 1950's, textile looms were churning out sixty million yards of this material a year. Just think how much they make today.
Here's an idea for a new product - Hook Loop (again, Hook Loop is a registered trademark for Hook Loop USA's brand of Hook and Loop fasteners) patches glued to the mouths of people that seem to never shut up and work. By the way, Hook Loop (and yet again, Hook Loop is a registered trademark for - you know who - Hook Loop USA - don't confuse them with the Hook and Loop Fasteners Hook Loop has a major problem - the name has become generic.
