INTRODUCTION What is smart? What kind of textile is smart? passive smart active smart very smart
SHAPE MEMORY MATERIALS * stable at two or more temperature states. * Shape memory polymers are materials, which have polyurethane, polyester-ether, poly nonbornylene, anti- polyisoprene, styrene-butadiene copolymer etc * shape memory polymer films are already finding application in clothing, like protection from cold, hazards of handling of hot fluids researchers in UK’s Defence Clothing &Textiles agency CHAMELEONIC TEXTILES: * temperature sensitive fabric by using micro capsules * microcapsule was made of glass, and contained the dyestuff, the chromotophore agent (electron acceptor) and color-neutralizer (alcohol),
HEAT STORAGE TEXTILES: * textiles can regulate their inner temperature according to local conditions. * to improve protection of instruments and astronauts against extreme fluctuations in temperature in space. * US air force and NASA planned to put the PCMs into gloves to keep pilot hands warm * temperature adaptable fabrics: * the thermal properties of fibre were modified. * the finished fabrics treated with PEG/DMDHEU had better heat-absorbing properties than the control fabric did.
INTUITIVE COMFORT SEAT: Elektex is used in the world’s first intuitive comfort seat, said to continually adjust itself to body movements. this sensitive fabric continually monitors body movement at the vehicle occupant’s back and under the legs to achieve optimum comfort and ergonomics. Electro textiles software and data algorithams interpret the information provided to drive seat positioning motors.
Self-cleaning clothes: * Bacteria impregnated into every single fibre of a fabric a vacuum pump is connected to the end of the hollow fibres from the milkweed plant. * A harmless strain of E-coli is genetically engineered to produce a fluorescent protein from a jellyfish. * shirt were impregnated with a strain of E. coli Spacesuits: * The inner layer of the spacesuit consisted of an under garment laced with a network of thin-walled plastic tubing inner layer was a comfort layer of lightweight nylon with fabric ventilation ducts. * Outside these came two layers of Kapton and beta marquisette for additional thermal protection.
DATA WEAR: * the body’s joints, plotting the position on a graph, * sensors are made from conductive elasmata. * bunch of magnetic position sensors system measures the angles of each of the joints Sport Jacket: * This is a jacket that can sense the arm movements of the wearer. * This could be used to monitor and assist people when playing sports. Smart Shoe: * Reebok have developed a smart shoe. * Traxtar measures how fast children run, how high they jump and how far they leap, giving them the opportunity to challenge themselves, and each other, in these skills.
Wearable Computer: A wearable computer (BWC), a battery-powered computer system worn on the user’s body (on a belt, backpack or vest), is designed for mobile and predominantly hands free operations, often incorporating head-mounted displays and speech input. Body wearable computing has been defined in several ways.
RECENT DEVELOPMENTS IN SMART PROSPECTS: Health care suit: * The suit monitors the weather and tracks surface characteristics * inside one’s bio-physiological state is detected. * smart card contains one’s personalized training program, * if something happens anyway, the suit can immediately call one’s doctor. Heat Insulating Clothing * thickness changes with the ambient temperature and metabolic heat. * to regulate its heat insulating ability automatically. * the thickness increases to hold more static air and increase heat-insulating ability. * the thickness decreases to hold less static air and reduce the heat insulating ability. Emotion Clothes: * These have the ability to assess the wearer’s mood. * T-shirts change color and/or release fragrance according to one’s mood.
CONCLUSION: Smart textiles have attracted more and more attention in recent years, and there will be a boom in research into their development and applications in the next few years. Now-a-days smart material is used in broad areas like military, vehicles, healthcare, space applications and so on. So the textile technologist should have their interest in this field for its development. By using the small textiles we can produce recyclable products such as keyboards…
