Velcro
Velcro IP Holdings LLC, trading as Velcro Companies and commonly referred to as Velcro (pronounced ), is a British privately held company, founded by Swiss electrical engineer George de Mestral in the 1950s. It is the original manufacturer of hook-and-loop fasteners, which de Mestral invented. History Swiss electrical engineer George de Mestral who studied at EPFL invented his first touch fastener when, in 1941, he went for a walk in the Jura Mountains, Jura mountains, and wondered why burdock seeds clung to his woolen socks and coat, and also his dog Milka. He discovered it could be turned into something useful. He patented it in 1955, and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s. The fastener consisted of two components: a lineal fabric strip with tiny hooks that could 'mate' with another fabric strip with smaller loops, attaching temporarily, until pulled apart. Initially made of cotton, which proved imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook-and-loop Fastener
Hook-and-loop fasteners, commonly known as Velcro (a Generic trademark, genericized trademark), hook-and-pile fasteners or touch fasteners are versatile fastening devices that allow two surfaces to be repeatedly attached and detached with ease. Invented in the mid-20th century, they are widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound. History The original hook-and-loop fastener was conceived in 1941 by Swiss engineer George de Mestral, which he named velcro.The word Velcro is a portmanteau of two French words: "velours" meaning velvet, and "crochet" meaning hook. The idea came to him one day after he returned from a hunting trip wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burdock
''Arctium'' is a genus of biennial plants commonly known as burdock, family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook and loop fastener. Description Plants of the genus ''Arctium'' have dark green leaves that can grow up to long. They are generally large, coarse, and ovate, with the lower ones being heart-shaped. They are woolly underneath. The leafstalks are generally hollow. ''Arctium'' species generally flower from July through October. Burdock flowers provide essential pollen and nectar for honeybees around August, when clover is on the wane and before the goldenrod starts to bloom. Burdock's clinging properties make it an excellent mechanism for seed dispersal. Taxonomy A large number of species have been placed in genus ''Arctium'' at one time or another, but most of them are now class ...

George De Mestral
George de Mestral () was a Swiss electrical engineer who invented the hook and loop fastener which he named Velcro. Biography He was born to Albert de Mestral, an agronomist engineer, and Marthe de Goumoëns in Saint Saphorin sur Morges, near Lausanne, Switzerland. De Mestral designed a toy airplane at age twelve and patented it. He attended the École polytechnique fédérale de Lausanne (EPFL). After graduation in 1930, he worked in the machine shop of an engineering company. He went for his favorite hobby of hunting and when he came back he discovered that his dog was covered with burs that had attached themselves to its fur. He then worked on inventing hook and loop fasteners for ten years starting in 1948. In 1955, he successfully patented hook and loop, eventually selling 60 million yards (about 55,000 km) a year through a multimillion-dollar company. Marriage De Mestral was married three times: in 1932 to Jeanne Schnyder (two sons: Henri and François), in 1949 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1952 Establishments In Switzerland
Year 195 ( CXCV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Generic Trademark
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, because of its popularity or significance, has become the generic term for, or synonymous with, a general class of products or services, usually against the intentions of the trademark's owner. A trademark is prone to genericization, or "genericide", when a brand name acquires substantial market dominance or mind share, becoming so widely used for similar products or services that it is no longer associated with the trademark owner, e.g., linoleum, bubble wrap, thermos, and aspirin. A trademark thus popularized is at risk of being challenged or revoked, unless the trademark owner works sufficiently to correct and prevent such broad use. Trademark owners can inadvertently contribute to genericization by failing to provide an alternative generic name for their product or service or using the trademark in similar fashion to generic terms. In one example, the Oti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crochet
Crochet (; ) is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread (yarn), thread, or strands of other materials. The name is derived from the French term ''crochet'', which means 'hook'. Hooks can be made from different materials (aluminum, steel, metal, wood, bamboo, bone, etc.), sizes, and types (in-line, tapered, ergonomic, etc.). The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and Broomstick lace, do keep multiple crochet stitches open at a time. Etymology The word crochet is derived from the French language, French word , a diminutive of ''croche'', in turn from the Germanic languages, Germanic ''croc'', both meaning "hook". It was used in 17th-century French lace-making, where the term ''Crochetage'' designated a sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velour
Velour, occasionally velours, is a plush, knits, knitted fabric or textile similar to velvet or velveteen. It can be made from polyester, spandex, cotton, or a cotton-polyester blend. Velour is used in a wide variety of applications, including clothing and upholstery. Velour typically has a medium-length Pile (textile), pile, shorter than velvet but longer than velveteen. History and uses Velour originated in France, although it is unclear who first created it. There is a 1591 entry in the accounts of Nathaniel Bacon of Stiffkey, Norfolk, England "''for half a yard of vellewre to make pomelles for the sydsaddelles"'' for 2 shillings cost. (Note this is in distinction to velvet ("''vellet'' ") found elsewhere in the accounts) . Velour is a knitted fabric, which makes it stretchy (unlike velvet and velveteen, which are woven). Velour is soft, allows freedom of movement, and is used for activewear and loungewear. Historically, velour was cheaper than velvet and was thus often used ...
