economy &
4th largest

4. We are using more
 Population – More People
 Demography – More People who need
 Income – More People who can afford
 Travel -Awareness
 Medical tourism – Attitudes
 Growth of healthcare industry – demand
 Products – Increasing Range of products

5. 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
• Newer products
• Largely import dependant

6. • Personal Hygiene
• Dressings & bandages
• Linen, Protective clothing
• Implantables
• Extracorporeal devices

Applications

9. Why we need them

10. Standards
 ‘A set of rules for ensuring quality‘
 'A technical specificationapproved by a
recognizedstandardizationbody for repeated
or continuous application,with which
complianceis compulsory , aimed at the
achievement of the optimum degree of order in
a given context‘

11. Why Standards?
MedTex products have crucial life-saving
applications

12. Standards
 Confidence - positive impact on consumption
 Internationally competitive
 Decrease dependence on imports
 Regulation of use

31. • Uniforms
• Back packs
• First field dressings (FFD)
• Shell dressings
• Tourniquet
SCOPE
Life saving army uniforms:
Engineersand scientists will work to
develop ideas such as a uniform that is
nearlyinvisible and soft clothing that can
becomea rigid cast when a soldier
breakshis or her leg.
- DuPont

33. Conclusion
• Textile-based materials for medical use are
helping to improve people’s lives—and in
some cases transform them.
• We have to leverage innovations in this field
to improve health care delivery and make it
affordable & safe.
• Standards are essential .
• Interesting changes in the market will follow.
