Swim Cap
A swimming cap, swim cap or bathing cap, is a tightly fitted, skin-tight garment, commonly made from silicone, latex or lycra, worn on the head by recreational and competitive swimmers. Swim caps are worn for various reasons: they can be worn to keep hair out of the swimmer's face, reduce drag, protect hair from chlorine or sun damage, keep hair dry, keep the head warm, or (sometimes in combination with earplugs) to keep water out of the ears. Caps can also be worn to identify skill level in swimming lessons. History Swim caps were made of rubberized fabric during the early 20th century. By the 1920s, they were made of latex. The earliest chin strap caps were known as "aviator's style caps" as they resembled the strapped leather helmets of flyers of the day. During the 1940s, swim caps became scarce as rubber was needed for war materials. The permanent wave hairstyle took time to obtain and was expensive, so many women wanted to protect their hair while swimming. The 1950s saw de ...

Oussama Mellouli 1
Osama ( ar, أسامة, ), alternatively Oussama and Usama, is an Arabic masculine given name. The name derives from the Arabic stem اسم A-S-M Alif Sin Mim "name" and means more or less "the one with a name". It is one of many Arabic male given names for "lion", the lion being considered as an animal with fame. From this point of view, ''sama'' is equivalent of the Latin name ''Augustus'', "majestic". In Hebrew the root is reduced to שם from Proto-Semitic *šim-, from Proto-Afroasiatic *(ʔi-)sim- ("name"), each denoting some aspect of the animal. In popularity, the name has declined drastically since 2001, mainly due to negative associations with al-Qaeda founder Osama bin Laden.

Skin-tight Garment
A skin-tight garment is a garment that is held to the skin usually by elastic tension using some type of stretch fabric. Commercial stretch fabrics ('elastomerics') such as spandex or elastane (widely branded as 'Lycra') came onto the market in 1962, and revolutionized many areas of the clothing industry. A wide variety of clothing may be made to be skin-tight, and it is common for clothing to be skin-tight for some uses, such as in stockings, bodystockings, swimsuits and women's bras. History and types Leotard In 1886, the name leotard was given to a one-piece skin-tight garment that covers the torso including the crotch, but not the legs or arms. The garment was named after French acrobatic performer Jules Léotard (1838–1870), many years after his death, who wore the garment in his acrobatic act. In the early 20th century, use of leotards was mainly confined to circus and acrobatic shows, but were also worn by professional dancers, such as the showgirls of Broadway. Leotar ...

Silicone
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non- vulcanized rubber. Such is the case in products like latex gloves, latex con ...

Lycra
Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia, US. The generic name "spandex", which is an anagram of the word "expands", is the preferred name in North America. In continental Europe, it is referred to by variants of "elastane", including (France), (Germany, Sweden), (Spain), (Italy), and (Netherlands); and in the UK, Ireland, Portugal, Spain, Latin America, Australia, and New Zealand, it is primarily known as "Lycra". Brand names for spandex include Lycra (made by The Lycra Company, previously a division of DuPont Textiles and Interiors), Elaspan (The Lycra Company), Acepora (Taekwang Group), Creora ( Hyosung), INVIYA ( Indorama Corporation), ROICA and Dorlastan ( Asahi Kasei), Linel (Fillattice), and ESPA ( Toyobo).

Competitive Swimwear
Competitive swimwear refers to the swimsuit, clothing, equipment, and accessories used in the aquatic sports of swimming, diving, synchronized swimming, triathlon, and water polo. Some swimsuits are designed specifically for swimming competitions where they may be constructed of a special low resistance fabric that reduces skin drag. For some kinds of swimming and diving, special bodysuits called "diveskins" are worn. These suits are made from spandex and provide little thermal protection, but they do protect the skin from stings and abrasion. Most competitive swimmers also wear special swimsuits including partial bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage. Unlike regular swimsuits, which are designed mainly for aesthetic appearances, swimsuits designed to be worn during competitions are manufactured to assist the athlete in swim competitions. They reduce friction and drag in the water, incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Children

Permanent Wave
A permanent wave, commonly called a perm or permanent (sometimes called a "curly perm" to distinguish it from a " straight perm"), is a hairstyle consisting of waves or curls set into the hair. The curls may last a number of months, hence the name. Perms may be applied using thermal or chemical means. In the latter method, chemicals are applied to the hair, which is then wrapped around forms to produce waves and curls. The same process is used for chemical straightening or relaxing, with the hair being flattened instead of curled during the chemical reaction. History The first person to produce a practical thermal method was Marcel Grateau in 1872. He devised a pair of specially manufactured tongs, in which one of the arms had a circular cross-section and the other a concave one, so that one fitted inside the other when the tongs were closed. The tongs were generally heated over a gas or alcohol flame and the correct temperature was achieved by testing the tongs on a newspaper ...

Open Water Swimming
Open water swimming is a swimming discipline which takes place in outdoor bodies of water such as open oceans, lakes, and rivers. The beginning of the modern age of open water swimming is sometimes taken to be May 3, 1810, when Lord Byron swam several miles to cross the Hellespont (now known as the Dardanelles) from Europe to Asia. In the first edition of the modern Olympic Games in Athens in 1896, the swimming competition was held in open water. In 2000, the Olympic Games first included a triathlon with a 1500 m swim leg, and in 2008, a 10 km open water swim. The FINA World Aquatics Championships has featured open water swimming events since 1992. The FINA World Open Water Swimming Championships was held from 2000 to 2010. Since 2007, the FINA 10 km Marathon Swimming World Cup is held in several events around the world. The activity has grown in popularity in recent years with the publication of bestselling books on "wild swimming" by authors such as Kate Rew and ...
