Body-responsive hollow fibre Hollow fiber has been scientifically proven to significantly increase oxygenated blood flow, which cans increase circulation and build strength. For diabetics, this improvement in skin oxygenation can accelerate wound healing and help eliminate pain due to decreased 90 blood flow. For people not affected by diabetes, this skin oxygenation helps speed recovery after exercise, boost energy levels and improve overall circulation. Diabetics face two major issues neuropathy, or the loss of sensation, and atherosclerosis, or hardening of the arteries, which reduces the circulation of blood in the body. Atherosclerosis can lead to a number of conditions, including aching feet, leg pain and problems with wound healing. Symptoms include cold feet, pain in the legs when walking and pain in the feet when reclining. When worn on or near the skin, Hollow fiber responds to available light and the energy produced naturally by the body, converting light and they body's own energy in to the necessary wavelengths that make this usually unavailable energy accessible to the body-improving the body's circulation and oxygen levels. In addition to helping diabetics, this breakthrough textile has been shown to improve physical performance and recovery time among those without circulation problems. Holofiber is already being lauded by some of the world's top athletes, including top ranked female triathlete and Olympic silver medalists Michellie jones, who has been testing Holofiber for nearly two years. "As a professional athlete, you want everything you can possibly find to help get the best performance possible, "she said."That's one of the things I like about Holofiber - the fact that it helps with recovery and circulation. What better way-there's no extra effort, and it really helps and benefits you." World's leading experts in diabetic foot complications, proved the effectiveness of Holofiber products in increasing oxygen levels in diabetic subject. There was a" ... statistically significant change in transcutaneous oxygen - or the oxygen delivery to the skin in hands and feet, on subjects wearing Holofiber gloves and socks compared to those wearing comparable nonHolofiber gloves and socks." Among the manufacturers already offering Holofiber products or planning to introduce them are wickers in its t-shirts, shorts, sock and glove liners, Super feet in custom insoles, Achieve 02 in diabetic and medical socks and Callaway Golf in shoes. Holofiber is a proprietary product with a patent pending. It is a responsive material for textiles and other uses, and is not an additive or coating applied by spraying or dipping. Its properties do not wash or leach out of the fabric. All of the Holofiber material are incorporated into the fibre and are non-toxic and biologically benign Polyester Formaldehyde Fumes Absorb Polyester A polyester fiber can be spun and woven into fabrics for upholstery, which will absorb the fumes released by the formaldehyde adhesives used to make furniture. The fibers, and so the fabrics made from them, contain a nitrogen compound that is firmly bonded to the surface. It is this that absorbs the gas. The tests are conducted in environments in which the level formaldehyde was as high as 14 parts per million [ppm]. The fabrics reduced this level to just 0.06 ppm in 24 hours, the upper safety limit is considered to be 0.08 ppm. This fiber so much useful in the industry, for worker apparel and other purposes also. Lightweight and air-insulating polyester fiber Sinkong Synthetic Fibers Corp. has adopted a new spinning technology to create Thermo Tech, a lightweight and air-insulating polyester fiber with a hollow cross-sectional area. The functional fiber is suitable for sportswear, thermal underwear, socks and bed sheets. The hollowness of the fiber can be up to 30 percent, yielding a lower fiber density and enabling air to be trapped within the fiber to preserve body heat. The firm, resilient fiber lends a cotton like hand, rich feel, wrinkle-free and easy-to-c1ean properties to fabrics. Thermo Tech is available in SDY and FOY versions in 60d/50f, 75d/50f, 75d/30f and 7 5d/36f specifications.
Kevlar Five times stronger than steel, Kevlar is a synthetic fiber of the DuPont corporation that was first created in 1965 by scientists Stephanie Kwolek and Herbert Blades. Since that time, Kevlar has been utilized in a wide variety of applications and has helped save thousands of lives through its use in bulletproof vests. Sometimes referred to as a Space Age material, it is the chemical structure and processing of Kevlar that makes it so strong. More specifically, Kevlar contains both aromatic and amide molecular groups. When molten Kevlar is spun into fibers at the processing plant, the polymers produced exhibit a crystalline arrangement, with the polymer chains oriented parallel to the fiber's axis. The amide groups are able to form hydrogen bonds between the polymer chains, holding the separate chains together like glue. Also, the aromatic components of Kevlar have a radial orientation, which provides an even higher degree of symmetry and strength to the internal structure of the fibers. Strength is not; however, the only advantageous feature of Kevlar fiber. Kevlar is also lightweight, flexible, and resistant to chemicals and flames. Together these characteristics make Kevlar extremely useful to humans. Some of the common items that contain Kevlar include sports equipment, such as skis and tennis rackets, highly protective gloves, parachutes, and tires. Kevlar is also frequently used to construct lightweight ropes, which have been used for such crucial applications as mooring the large vessels of the United States Navy and securing the airbags in the landing apparatus of the Mars Pathfinder. Fiber optics Optical fibers are thin strands of super-clean glass (fused silica), about the size of a human hair. Almost all fibers used today are single strands. Fiber bundles find use primarily in coherent and image transmitting optical systems. There are also plastic fibers for inexpensive, short distance transmission. The basic design of an optical fiber consists of two components - the core and the cladding. They build an optical waveguide, which conducts optical power (photons) in the form of light rays. Core and cladding differ primarily in the refractive index of the glass. The core's refractive index is slightly higher than the cladding's, thereby creating a boundary for a circular waveguide. Fiber optic signaling in data transmission is increasingly being used in high-density applications. In the military, the Standard Electronic Modules (SEM) of the Standard Hardware Acquisition and Reliability Program (SHARP) are widely used for high density electrical interconnects in card-edge-to-backplane interfacing. The advantages of fiber optics can be summarized as: • Insensitive to EMI, RFI and EMP • Does not radiate energy • Low transmission losses • Wide transmission bandwidth • Unaffected by Lightning • Lightweight & non-corrosive
