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 d ...

Skin-tight Garment
A skin-tight garment is a garment that is held to the skin usually by elasticity (solid mechanics), 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 brassiere, 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, su ...

Silicone
In Organosilicon chemistry, organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (, where R = Organyl group, organic group). They are typically colorless oils or elastomer, 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, grease, silicone rubber, rubber, silicone resin, resin, and Caulking, caulk. Silicone is often confused with one of its constituent elements, silicon, but they are distinct substances. Silicon is a chemical element, a hard dark-grey semiconductor, semiconducting metalloid, which in its crystalline form is used to make integrated circuits ("electronic chips") and solar cells. Silicones are compounds that contain silicon, carbon, hydrogen, oxygen, and perhaps other kinds of atoms as well, and have many very different physical and chemical ...

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latices are found in nature, but synthetic latices are common as well. In nature, latex is found as a wikt:milky, milky fluid, which is present in 10% of all flowering plants (angiosperms) and in some Mushroom, mushrooms (especially species of ''Lactarius''). It is a complex emulsion that coagulation, coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, Vegetable oil, oils, tannins, resins, and Natural gum, 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 Antipredator adaptation, defense against Herbivore, herbivores and Fungivore, fungivores.Taskirawati, I. and Tuno, N., 2016Fungal defense against mycophagy in milk caps ''Science Report Kanazaw ...

Lycra
Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity (physics), elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont. Name The 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''. It is primarily known as ''Lycra'' in the UK, Ireland, Portugal, Spain, Latin America, Australia, and New Zealand. Brand names for spandex include Lycra (made by The Lycra Company, previously a division of Invista, 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 (sport), swimming, Diving (sport), diving, artistic swimming, triathlon, and water polo.

Most competitive swimmers wear special swimsuits including partial bodyskin, bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage. For diving in water temperatures above 25 °C (77 °F), special bodysuits called "Diving suit#Dive skins, dive skins" are worn. These suits are made from spandex and provide little thermal protection, but they protect the skin from jellyfish stings, sunburn, and abrasion. This kind of suit is also known as a 'Stinger Suit'. Some divers wear a dive skin under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair
Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, gender, or religion. Overview Meaning The word "hair" usually refers to two distinct structures: #the part beneath the skin, called the hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 newspape ...
