Introduction to technical textiles2

  1. 1.  Term technical textile was coined in 1985, other terms used for defining technical textiles are industrial textiles, functional textile, performance textile, engineering textile, invisible textile and hi-tech textile.  Technical textiles is a knowledge based research oriented industry.  The global technical textile has shown an increase from 25%(1998) to 37% (2010).  The largest segment are mobiltex, Indutex and sportek and they contribue to about 55-57% of the total technical textile on global basis.
  2. 2.  The market size of technical textiles in India is estimated at Rs. 63, 202 Crore during the year 2011-12 with a growth rate of 11% per annum, & expected to increase at a growth rate of 20%.  India Textile Ministry estimates the market size of technical textiles in the country to reach US $28.7 billion from the US$ 10.3 billion (2010-11)  Total employment given by technical textile - 8.8 lakh persons  Total Exports - $ 12.6 billion  Centers of Excellence (COEs): Four COEs are BTRA for Geo- tech, SASMIRA for Agro-tech, NITRA for Pro-tech & SITRA for Medi-tech.
