3. Introduction Technical Textiles (TT) offers new ways, means and opportunity to the Indian textile industry to sustain the present growth and thrive in near future. Textile industry is normally considered as an industry which fulfills the demand like climate protection, increase in the aesthetic sense, over and all apparel need & this sector is then well known as traditional textile or general textile . On the other hand, due to human demand , textile sector has been given many names but the most common are technical textile, industrial textile, and functional textile.

4. History Technical textile touched its peak as soon as the manmade fibre was discovered in1900 AD , bwas developed to manufacture the technical textile. In the last three hundred years, world has observed a fast growth in fiber production which has a very distinguished characteristics such as High resistance to temperature Stable under stress and strain Strong enough to absorb impact before that the only source was the natural fibres & it was treated with chemicals to make the same. Simultaneously new technology such as special weaving process, nonwoven technique etc of highly reactive chemicals etc. Textile industry has created various products by using such fibres .

5. Definition The technical textiles is defined as textile material and product manufactured primarily for their technical performance and functional properties rather than their aesthetic or decorative characteristics. OR A Technical textile is a textile product manufactured for non-aesthetic purposes, where function is the primary criterion. It is a large and growing sector and supports a vast array of other industries.  

6. Definition Technical approach : Old Technical textiles are considered all fabrics that can not be addressed within the traditional sectors of clothing, home and decoration. Present Technical textiles are specially designed and engineered structures that are used for their technical p erformance and functional properties rather than their aesthetic properties Market approach : Technical textiles offer solutions for the manifold technical challenges existing in our society (environmental, protection, personal safety, general safety, health & well-being)

21. Medi -tech ( Medical textiles) Combination of textile technology and medical sciences has resulted into a new field called medical textiles. Applications Woven and nonwoven gowns and drapes Woven and knit wound care product Medical mattresses Wipes Cover stock….

22. Raw material for technical textile First synthetic fiber, acetate, was invented in 1799 known as artificial silk. Later in 1894, it was known as Viscose and in 1924, it was called Rayon and invention of polyester, which in 1953. There is a long list of synthetic fibers, which are available today, and frequently used in every new product. Discussion on the development of synthetic fibers is out of the scope of this article. Until the manmade fiber was discovered the natural fiber was the key source for technical textile manufacturing. The mostly used natural fibers were cotton, wool, jute, linen, etc. Till date competing with manmade fiber the cotton & the jute has kept a good share market as a key raw material for technical textiles.

28. Indian Scenario A systematic survey had been undertaken by Ministry of Textiles (MOT) to assess the progress of technical textiles in India. With this study, it is established that India is yet to find a significant place in the global scenario in this area. Traditionally, Indian textile industry is composed of four sectors, viz., composite mill sector, decentralised powerloom , hosiery and handloom sectors. Indian textile industry was dominated by the composite mill sector in the post-independence period. Technical textiles did never find a place of priority in this sector, though a few mills produced a limited range of industrial textiles in their product mix.

29. Present Scenario Of Technical Textiles India is the world second largest producer of textile and garments. The textile industry in India contributes 14 % towards the GDP of USD 1.18 billion. This market itself being so big, there is tremendous potential for technical textiles as well. Currently the consumption of technical textiles in India forms only 3 % of the total world consumption; however, it is growing at a rate higher than most developed countries. The reasons for low penetration in this market are several, such as scattered production structure, inadequate research and development (R&D), lack of skilled personnel. Another major contributing factor is that there is lack of awareness about the benefits of using technical textile

30. A India still has to make its presence felt in the world technical textiles market, which earns that a highly unexploited market is waiting to be explored.

31. Market Size Market size during 2012-13: rs 70,151 crore Expected in 2014-15: rs 1,09,659 crore Expected to be rs 1,58,540 crore by 2016-17 @ 20% growth

32. Ministry Of Textile Initiatives Technical Mission On Technical Textiles ( Tmtt ) Objectives Are “Standardisation, Creating Common Testing Facilities With National /International Accreditation, Indigenous Development Of Prototypes And Resource Centres” Have 8 Centre Of Excellence At Mumbai (2), Ghaziabad, Coimbtore (2), Kolhapur, Ahmedabad And Thane.

33. Recent development in technical textiles Electronic textiles are normally known as the e-textiles or smart textiles. Here are some example of this type of textile: Sports shoes Wearable computer jackets Warning vests Photonic textiles for innovative lighting solutions Wearable E-Health system Electronic Textiles to Help Battlefield Medics Global positioning system (GPS) jackets.  Breathable artificial fabric

34. Current Technology ZOLL Life Vest Wearable defibrillator If heart palpitations or an alarming rhythm of the heart is detected, the vest gives a signal to the patient. If the signal is not stopped by the patient, then the defibrillator gives off the conducting gel, then sending a shock to the patient. Vivo Metrics Life Shirt Places ECG sensors on the body, which then the data is transmitted to the data recorder, which is then transmitted to the doctor. Sensatex Smart Shirt Developed by Georgia Institute of Technology T-shirt with a fiber grid – data is then wirelessly transferred to a PDA with Bluetooth technology .

35. Future Technology Weather proof and waterproof systems Possibly smart textiles that can be worn outside the comfort of the home. Wireless transmitters that can collect data even outside 4g ( bluetooth ) areas. Smart textiles for children Commercialization Automatic calibrations Data can be sent to doctor via smart phone application or tablet application The doctor can collect data in real time. Integration of other fabric materials that could help improve versatility

36. Conclusions In 2011 India had 4% share in the global market size of technical textiles. The technical textiles has both import and export potentials . Technical textile sector in India is one of the fastest growing segments of the Indian economy. During 11 th five year plan it has registered compounded annual rate of growth of 11%. Technical textile market size is of the order of 109659 crore (us $ 17909 mn ) of 2014-15 and expected to grow at cagr of 20% and reach rs 158540 crore (us $ 25893 mn ) by 2016-17 .
