The spectrum of application of the textile fibres has been broadened with the advent of areas like Geo – Textiles, Industry, and Building – construction, Medical field, Automotives, Agriculture, Sports, Clothing, and Packaging have widened the reign of textile fibres-The Emperors of Industry. This paper discusses the properties of the textile fibres, which are necessary for their application in the industry as technical textile. Some of the most widely used textile fibres are reviewed in brief. The application of the textile fibres in various fields in the industry has made them the conquerors in the technical textile sector. The industrial applications of the textile fibres include reinforcements in the tires, and plastics, electrical insulations, industrial ropes, coated fabrics, filtration fabrics, etc. The paper puts light on each of these applications in brief. Various fibres used for the reinforcement in the tire have also been discussed. However, the cost of these fibres has confined their applications so there is an urgent need of developments in this field to develop novel processes, which can reduce the cost of production of the fibres, so the application can be extended further.
