[ Technical Textiles - Mantra, IPR pact for plasma tech research on yarns & fabrics .]

SURAT: The man-made synthetic textile hub of Surat is all set to play a major role in new generation of textiles which have applications in space, defence, advance communication, medical textile and intelligent textile with the help of plasma technology.

The Man-Made Textile Research Association (MANTRA) and the Gandhinagar-based Institute of Plasma Research (IPR) have signed a Memorandum of Understanding (MoU) to take up various projects for the coated fabrics which are used in technical textiles. These would be focussed towards enhancing their structural stability, adhesion and bond power and also work to make them anti-microbial, water proof, UV resistant, flame retardant through plasma coating technology by using metals like silver, nickel, copper etc.

The MoU, signed a couple of days ago in Gandhinagar, has five different projects. These have been approved by the department of science and technology (DST), Government of India under the instrument development programme with each project likely to cost Rs.1 crore.

The projects to be undertaken by IPR and MANTRA are: plasma and corona treatment for improving the adhesion and bonding in coating and lamination for technical textiles, silver coating on polyester film or yarn by physical vapour deposition (PVD) for the production of pure silver jari for high end product, production of nano titania powder and integration in synthetic textiles for self-cleaning properties as well as giving a dull finish to polyester, plasma nitriding for surface hardening of textile machinery components and plasma pyrolysis for disposal of textile waste material.

"AT present the coating on yarn and fabric is done using inorganic materials and chemicals, which in turn damage the environment as well as the fabric in the long run. The plasma technology along with the combination of bio-technology and nano technology will go a long way in minimising the effects and use of chemicals on yarn and fabrics," said Arun Jariwala, chairman of MANTRA.

According to Jariwala, spirit and other chemical substances are used in the coating on yarn and fabrics of technical textiles. In the plasma technology, the coating will be done using silver's nano particles on the yarns and fabrics. Such fabrics could be used in the manufacturing of technical textiles for use in medical, advance communication, space, defence sector etc.

A senior researcher at IPR said, "The plasma process could prove a clean and green technology in the technical textile sector. It has a very low environmental impact through its low water, energy and chemical usage."

Jariwala said, "We have tied up with the city-based Himson textile engineering group for making a model of the plasma technology instrument."
