The natural fibers (cotton, wool, silk . . .) have a high aesthetic appeal in fashion fabrics (clothing, upholstery, carpets...):Until 100 years ago, they were also the fibers used in engineering applications –what are called technical or industrial textiles. The smart fibers with some special physical or chemical properties, which give a new dimension to the use of textiles. High-performance fibers are those that are engineered for specific uses that require exceptional strength, stiffness, heat resistance, or chemical resistance. The development of special fibers is the consequence of merging fundamentals scientific and technical knowledge, as there is a quest for high-performance fibers, used in fabric applications ranging from bulletproof vests to trampolines, must have a sufficient number of chemical and physical bonds for transferring the stress along the fiber. The fibers should possess high stiffness and strength. Stiffness is brought about by the degree to which the chemical bonds are aligned along the fiber axis. High-performance organic fibers have also become very important in recent years. Aramids are among the best known of the high-performance, synthetic, organic fibers. Teijin has developed high performance aramid fibers which are applicable for ballistic protection, cut protection, friction protection, optical fiber application, rope cable application, heat protection and composites.

On a broad outlook it appears that textiles have no application other than apparel purposes. But as a matter of fact, there are non-apparel uses of textiles such as technical applications. It offer several advantages in their functional aspect for improving health and safety, cost effectiveness and durability and strength of textile material. Technical textiles are the emerging field in India and globally. They are defined as textile materials and products made principally for their functional properties and technical performance and rather than their aesthetic or decorative characteristics. On the basis of the functional, technical performance and end use, technical textiles are classified in to 12 categories namely Agrotech Buildtech, Clothtech , Geotech, Hometech, Indutech (Filtration, cleaning and industrial), Meditech, Mobiltech, Oekotech (Environmental protection), Packtech (Packing materials), Protech, Sportech. This clearly shows us that the technical industry is not a single industry, it caters to a wide gamut of industries right from agriculture to automobiles to construction activities, among others. Automobile is the lifeline of present society. Trade, Industry and Commercial activity extremely dependent on this sector. This automotive sector consumes a lot of textile materials that may be visible or concealed in automobile. The global consumption of textiles used in automobile industry is estimated to be over 4.5 lakh tonnes. The percentage of textile material used in motor car amounts to 2.2% of the overall weight of the car. Apart from traditional uses as interior fabrics, carpets, headliners, etc., textiles are also being used as tyre cord, fuel filters, safety belts, air bags and as a reinforcement material for composites.
