Nonwovens For Value-Added And Defense Applications

Nonwovens are part of technical textiles which find applications predominantly in disposable and semi-durable sectors. The nonwoven industry became an organized sector during the late 1960s and early 70s with the formation of the Association of the Nonwoven Fabrics Industry (INDA) in the USA and the European Disposables and Nonwovens Association (EDANA). According to Ian Butler of INDA, worldwide growth of the nonwovens industry is estimated to be 7.9 % which will be worth over $ 30 billion by 2012. The per capita consumption in developed countries is over 3 kilograms. However, the nonwoven industry in India is in its very early stage with the per capita consumption of less than 100 grams. The annual production in India is around 80,000 tons as compared to 900,000 tons in China. As the middle class population in India is growing, which is set to reach half a billion by 2030, there will be need for lifestyle improvement products that use nonwovens in many different ways. These include baby diapers, feminine hygiene products, medical care products, automotive textiles, etc. This lecture will highlight recent projects that utilize nonwovens and nanofiber technologies for developing value-added textiles that have applications in military. In addition, the growth pattern of Indian technical textiles industry will be discussed as the contribution of the growing Indian technical textile industry to the global technical textile industry will be very important.


Growth Scenario of Indian Technical Textiles Industry


It is fairly well-accepted in the nonwovens and technical textiles industry that the consumption pattern of technical textiles/nonwovens is directly related to the GDP per capita income. The rise in the income levels will lead to rise in the middle class population which in turn will lead to increase in the production and consumption of nonwoven and technical textiles. A recent study by Ramkumar and Arunachalam has shown that based on World Bank GDP statistics, Indias technical textile industry will grow at 13.3 %. This estimate was carried out in mid 2008, when the growth rate of Indian GDP was predicted to be around 9%. With the current global economic turmoil, the growth rate for India has slightly come down and it shall be between 7-8%. This rate is far higher than the expected growth rate in the United States and Europe. As the GDP in India will be growing around 7-8 %, nonwovens and technical textile industry are set to grow at least to this level (around 8%). The target for the Indian textile industry is $150 billion by 2015, of which 10 % should be from technical textiles sector. Government of India has realized the potential of technical textiles industry to the overall Indian textiles industry and has created supportive schemes such as:


1. Technology Upgradation Fund, which now encompasses technical textile sector.

2. Creation of four Centers of Excellence which will focus on agrotextiles, geotextiles, protective
textiles and medical textiles.


3. Creation of awareness in nonwovens and technical textiles by conducting workshops and
seminars around the country.

4. Establishment of a five year National Technological Mission on Technical Textiles.
