Darlexx
Darlexx, a product of the Shawmut Corporation, is a warp knit fabric laminated to a monolithic film. It is a sports performance fabric used in gloves, boots, wet suits, ski apparel, clean rooms, and in medical applications. It was designed to keep a person "warm when the environment is cold and cool when the environment is hot" and is breathable, windproof, and waterproof. It is also useful in applications in specialty orthopedic garments and clothing along with coverings for different seating and positioning systems on wheelchairs. Types There are two variations of Darlexx: *Darlexx Superskin, a two-ply nylon and Lycra mix that provides less drag, and thus is used for competition swimming, skiing and running apparel. *Darlexx Thermalastic, a three-ply Lycra with thermoplastic film and microfiber Microfiber (or microfibre) is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers. A strand of silk is about one denier and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warp Knitting
Warp knitting is defined as a loop-forming process in which the yarn is fed into the knitting zone, parallel to the fabric selvage. It forms vertical loops in one course and then moves diagonally to knit the next course. Thus the yarns zigzag from side to side along the length of the fabric. Each stitch in a course is made by many different yarns. Each stitch in one wale is made by several different yarns. History Credit for the invention is usually given to a mechanic called Josiah Crane in 1775. He likely sold his invention to Richard March who patented (No. 1186) a warp frame in 1778. In the intervening three years March likely had discussed the device with Morris who submitted a similar patent (No.1282) for a twisting machine for making Brussels point lace. These early machines were modifications of the stocking frame with an additional warp beam. In 1795, the machine was successfully used to make lacy fabrics. Warp frames could be used with any thread, and the warps provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheelchair
A wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability. These can include spinal cord injuries ( paraplegia, hemiplegia, and quadriplegia), cerebral palsy, brain injury, osteogenesis imperfecta, motor neurone disease, multiple sclerosis, muscular dystrophy, spina bifida, and more. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand ("self-propelled"), by an attendant pushing from the rear using the handle( ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

Microfiber
Microfiber (or microfibre) is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers. A strand of silk is about one denier and about a fifth of the diameter of a human hair. The most common types of microfiber are made variously of polyesters; polyamides (e.g., nylon, Kevlar, Nomex); and combinations of polyester, polyamide, and polypropylene. Microfiber is used to make mats, knits, and weaves, for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are chosen for specific characteristics, including softness, toughness, absorption, water repellence, electrostatics, and filtering ability. History Production of ultra-fine fibers (finer than 0.7 denier) dates to the late 1950s, using melt-blown spinning and flash spinning techniques. Initially, only fine staples of random length could be manufactured and very few applications were found. Then came experiments to p ...

Polar Fleece
Polar fleece is a soft napped insulating fabric made from polyester. Uses Polar fleece is used in jackets, hats, sweaters, sweatpants, cloth diapers (nappies), gym clothes, hoodies, pajamas, blankets, and high-performance outdoor clothing. The produced fleece can be used to create clothes that are very light, soft, and easy to wash. Polar fleece can stretch more easily in one direction than in others. History Polar fleece originated in Massachusetts in 1979 when Malden Mills (now Polartec LLC), and Patagonia developed Synchilla (synthetic chinchilla). It was a new, light, strong pile fabric meant to mimic, and in some ways surpass, wool. Malden Mills CEO Aaron Feuerstein intentionally declined to patent polar fleece, allowing the material to be produced cheaply and widely by many vendors, leading to the material's quick and wide acceptance. Malden Mills registered PolarFleece as a trademark with the United States Patent and Trademark Office on October 6, 1981. Characteri ...

Synthetic Fibers
Synthetic fibers or synthetic fibres (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms, such as plants (like cotton) or fur from animals. They are the result of extensive research by scientists to replicate naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). Early experiments The first fully synthetic fiber was glass. Joseph Swan invented one of the first artificial fibers in the early 1880s; today it would be called semisynthetic in precise usage. His fiber was drawn from a cellulose liquid, formed by chemically modifying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
