Textile has always been a part of healthcare

Combination of Textile Technology and Medical Sciences has resulted into MEDICAL TEXTILES.

Medical Textiles are one of the faster growing sectors of the global Technical Textile industry.

Medical textiles make up 19% of technical textiles.

3

Application of textiles has started going beyond the usual wound care, incontinence pads, plasters etc.

Latest innovation ie., wide variety of woven, non woven, knitted forms of textile are increasingly finding their way into a variety of surgical procedures.

4

The use of textile materials for medical and healthcare products can be classified into following main areas –

Barrier material (for infection control, gowns / drapes, masks) Bandaging & pressure garment Wound care material Hygiene material (Diapers / adult incontinence diapers/wipes etc) Implantable material (sutures, art. Joints etc) Extra Corporal devices (like art. Kidney etc)

5

Requirements of textile material for medical applications Biocompatible Good resistance to alkalis, acids and micro-

organisms Good dimensional stability Elasticity Free from contamination or impurities Absorption / Repellency Air permeability.

6

In India, traditionally medical textile segment is dominated by Woven Textiles

But, new technology Nonwoven products have provided innovative product options

Nonwoven textiles play a significant role in the medical sector. The product range includes surgical gowns, masks and other wearable products; surgical drapes, pads; dressings; filtration materials; and implantable textiles such as tissue scaffolds for rebuilding internal organs, among other products.

By far, most nonwoven products used outside the body are disposable, single-use articles that have the advantage of not requiring sterilization or cleaning for reuse.

7

Reusable / Durable to Disposable :

Concept of reusing linen of yester year is slowly getting eliminated and shift to single use disposable products is the norm of the day in many of the Hospitals.

Great transformation in the mode of treatment offered by hospitals, encouraging usage of disposables.

Medical tourism

Shift from conventional cutting & preparing of gauze pieces to precut gauze pieces, since 2000.

8

Why shift to disposables?

To prevent nosocomical infections Reusable linen - a carrier and source of infection. Increased awareness – among medical professionals/

healthcare workers and patients. To reduce overall healthcare costs to the nation by using

disposables in order to reduce cross infections. Surgerywise / procedurewise custom disposable pack /kit. Usage of wrappers instead of pink/green cloth covers, to

retain sterilization and increase the number of days storage.

9

Why shift to disposables?

Resistant to liquid penetration (Blood / Water), come into contact from cuts or spattering , results in exposure to pathogens.

Non linting (Burrs / loose particles will not come out).

Saving of time and man power in cutting and preparing the gauze pieces.

Resistant to flame & Infection free nature (barrier against bacteria).

10

Why shift to disposables? Allows air and moisture to pass through (better breathing /

better circulation, resulting in surgeon’s comfort).

Economic aspect

Ease of use, hygiene and cost effective, by eliminating laundering (washing of 1 ton of linen,7 ton of water – approx. required).

Innovative products Role played by fibre - based materials has advanced dramatically in recent

years….

Textile scaffolds to promote cell growth and build the cell structures Bioglass fibres used in tissue engineering to create new bone

structures. Textile based stents (Biocompatible / Biodegradable). Bandages - advanced dressings for wounds and burns, delivering

antibiotic and other drugs directly to the parts of the body. Casts – moisture curing resins and glass fibres offering light weight

and more comfortable alternative to plaster of Paris. Textile fibres and conduits are developed to guide nerve reconnection

and regeneration.

17

Innovative products in Medical Textiles

Bio functional materials - active substances are incorporated into fibre by chemical modification or applied onto fibre during spinning process

These additives get transferred to skin by body moisture or by body heat.

eg.,anti-allergen finishing agents used to relieve patients from asthma.

18

Innovative products in Medical Textiles

Photonic Textiles Philips demonstrates photonic textiles that turn fabric into

intelligent displays. eg., a baby jaundice sleeping bag, embedded with blue

LEDs to break bilirubin is developed.

Mesh sack Manufactured from warp knitted polyester to prevent

heart enlargement for patients with degenerative heart failure.

19

Global scenario In North America, disposable nonwoven medical apparel

products alone represent a market totaling nearly $1.46 billion, according to the Association of the Nonwoven Fabrics Industry (INDA), and the market is growing by approximately 1 to 2 percent annually.

Globally, the medical nonwoven disposables market is forecast to grow to $12 billion by the end of 2010

Demand for wound management supplies will reach $8.7 billion in 2013.

20

Dressings based on alginate, foam, collagen and growth factor substances will post the best gains based on expanding applications in the treatment of moderate-to severe lacerations.

Tissue sealants composed of cyanoacrylates and bioengineered fbrins will also fare well in the marketplace based on superior binding traits and fast healing advantages.

Trends toward less invasive surgery will weaken the overall market for wound closures.

21

Class IV surgical drapes and gowns will post the strongest sales gains among nonwoven medical textiles (surgical infection prevention)

Disposable face masks will also fare well in the marketplace, beneftting from routine use by medical providers in virtually all direct contact patient procedures.

Enhanced absorbent, odor neutralized diapers and shields will see the fastest gains in demand among incontinence products based on comfort and protection advantages.

Non Woven Textiles Market

Disposable non woven textiles will dominate Medical Textiles market.

Demand for hygiene products will go huge.

Current Indian non woven textiles is 70 thousand tons

In next 10 years,1 million ton of non woven textiles is the production level expected.

China producing today 1 million ton of non woven textiles.

26

Conclusion Medical Textiles are one of the dynamically

expanding sectors Aim is to convert painful days of patients

into comfortable days. As medical procedures continue and

transform, the demand for textile materials is bound to grow further and further.
