The technical advances are dramatically influencing the world of fibers, fabrics and textiles. Today, technology can provide us with fabrics that imitate and actually improve upon nature's best fibers. It is important to be aware of technological developments when fashion designing so that the best and most relevant fabrics may be used for the job. Consumers are demanding qualities from textiles that will enhance their lifestyle such as: comfort, performance, fit, shape retention, trans-seasonal versatility, quality and style, added value, lightweight properties and ecological integrity. The consumer will continue spending where they see innovation. There are many forward-thinking ideas in fibre and fabric manufacturing. There follows a range of fibre and fabric areas under development. In the next millennium, textiles will not just be an extension or simple alternatives to natural or synthetic fibers, but will provide superior functionality in broad and emerging sectors of the economy from space to super conductivity and agriculture to geo-textile. This will be accomplished through modern business strategies for enhanced stakeholder value and highly efficient production schemes with no adverse impact on the environment and development of precisely specified molecules for new textile platforms.

In a sense, all fibers except the cheapest commodity fibers are high-performance fibers. 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.
