SCENARIO
• Application of textiles has started going beyond the
usual wound care, incontinence pads, plasters etc.,
• In India, traditionally the segment is dominated by
Woven Textiles. Lately, Nonwoven products have
provided innovative product options
•
Current Domestic Consumption
• By 2012-13
• Heavily Import Dependent
• Unorganized Segment
Rs 2365 cr
Rs 3737 cr
Why Are Textiles A Good Choice?






Easy handling, manipulating and fashioning
Flexibility and suppleness
Pores
Mechanical strength
Good flex fatigue resistance
Proven clinical history.
Textile-based materials for medical
use are helping to improve people’s
lives—and in some cases transform
them.

 Bones -Textiles are replacing metal implants
 Nerve guidance channels
 Tissue Engineering
 Scaffolds
 Embroidery technology
SPIDER SILK - Exceptional
mechanical properties
 Five times stronger
than steel yet soft
enough to be woven
into a bulletproof
vest.
 Toughness : would be
able to catch an F-16
aircraft if the silk
were as thick as a
washing line.

SCOPE
• Uniforms
• Back packs
• First field dressings (FFD)
• Shell dressings
• Tourniquet
Life saving army uniforms:
Engineers and scientists will work to
develop ideas such as a uniform that is
nearly invisible and soft clothing that can
become a rigid cast when a soldier
breaks his or her leg.

Conclusion
• Medical textiles are a product of
collaboration between medical researchers
and textile scientists with immense scope
and applications.
• Time is ripe to make the most of this
expertise to raise the standards of health care
delivery and make it comforting, convenient,
affordable & safe.
• Interesting changes in the market will follow.
