2. Medical Textile
 All textiles used in operative and post-operative tasks in and around a patient
and the medical practitioners are termed as medical textiles. These highly
specialized and bio-compatible technical textiles used for medical and
hygiene applications are called MED-TECH.
 Medical textiles are one of the most rapidly expanding sectors in the
technical textile market.
 Some of the important field of application of textile in medicine are wound
care and preventing chronic wounds. Bandages and wound dressings are most
commonly used because they are affordable and reusable.
 The major characteristics of medical textiles are non-toxicity, non-allergenic
and ability and ability to be sterilized. Medical textiles should also have good
strength, elasticity, biocompatibility, durability, and flexibility depending
upon the product.

3. Fibers in Medical Field
 Natural Fibers
Like ( Cotton, wool, silk )
 Synthetic Fibers
Like ( Polyester, polyamide, polypropylene, polytetrafluoroethylene, glass fiber,
carbon fiber, polyglycolide, PVT fiber… etc.)

4. Uniqueness of Fibers used in Medical Textiles
 Pure and Hygienic
 Bio- degradable
 Fast and High absorbency
 Excellent wicking performance
 Barrier to percolation
 Good Insulation
 Good thermal stability
 High strength
 Low lint
 Soft fell
 Excellent drape ability
 Breathability
 Static dissipation
 Engineered specialties
-Anti- bacterial properties
-Medicinal clothing

5. Properties of the medical textile as follows:
 Medical textiles must be non-toxic and non-allergenic.
 It must be compatible with the most living system.
 It should be sterilized without imparting any change in
physical and chemical characteristics.
 If necessary, it should be versatile in their physical form
like powder form, aqueous form, film, fiber, sponges, etc.
 It should have enough lightness, strength, elasticity,
softness, etc.

6. Medical Textile Market Segmentation
by Type & Application

8. Implantable
Used in effecting to the body whether it is wound closure (sutures) or
replacements surgery like vascular grafts, artificial ligaments.

9. Non- Implantable
Used for external applications and may or may contact with skin.

10. Healthcare & Hygiene
Used either in the operation theatre or in the hospital wards for hygiene, care
and safety of the staff and patients.

11. Extra corporeal
Used as mechanical organs that for blood purification and include artificial
kidney, the artificial liver and the mechanical lung.

12. Non-implantable Materials
These materials are used for external applications on the body and may or may
not make contact with skin. Some of the common non-implantable materials are
wound care fabrics and absorbent pads, bandages, plasters, gauzes, lint, and
wadding.

13. Wound Care
The functions of these materials are to provide protection against infection,
absorb blood and exudates, promote healing, and, in some instances, apply
medication to the wound. Common wound dressings are composite materials
consisting of an absorbent layer held between a wound contact layer and a
flexible base material.

14. Extracorporeal Devices
Extracorporeal devices are mechanical organs that are used for blood purification
and include artificial kidneys (dialyzer), artificial liver, and mechanical lungs.
The function and performance of these devices have found a facelift with the use
of newer fibers and modern textile technology.

15. Artificial Kidney / Dialyzers
The function of the artificial kidney is achieved by circulation the blood through
a membrane, which may be either a flat sheet or a bundle of hollow regenerated
cellulose fibers like hollow viscose or hollow polyester fiber in the form of
cellophane that retain the unwanted waste materials. The kidney dialysis
machine is outside the body and purifies the blood using a filter called Haemon
dialyzer.

16. Artificial Heart
The artificial heart is intended for use in patients whose hearts have been
irreparably damaged, and for whom, existing methods of surgical intervention
and/or drug therapy are inadequate.

17. Artificial Lung
The microfibers or the membrane oxy-generator are the technical textile
component in this device. The microporous membranes of the mechanical lung
possess high permeability to gases but low permeability to liquids and function in
the same manner as the natural lung allowing oxygen to come into contact with
the patient’s blood.

18. Implantable Materials
These materials are used in the effective repair of the body whether, like wound
closure (sutures) or replacement surgery (vascular grafts, artificial ligaments).
Bio-combability is of prime importance.
Four key factors determine how the body reacts to the implant.
 The most important factor is porosity, which determines the rate at which
human tissue will grow and encapsulate the implant.
 Small circular fibers are better encapsulated with human tissue than larger
fibers with irregular cross-sections.
 Toxic substances must not be released by the fiber polymer, and the fibers
should be free from surface contaminants such as lubricants and sizing
agents.
 The properties of the polymer will influence the success of the
p=implantation in terms of its biodegradability.

19. Artificial Ligaments
 An artificial ligament is a medical device for joining the ends of two bones.
The artificial ligaments are made from man-made fibers like polyester.
 The artificial ligament is a multi-layered or tubular woven structure having an
intra-auricular region, with at least one bend and end region. Each region is
woven to possess the required flexibility and strength.

20. Artificial Skin
 Skin grafting is the procedure of replacing dead skin with live skin. After
removing burnt/damaged skin, surgeons blanket the wound with a covering
(artificial skin) before applying a skin graft on top of this bio-material to
encourage the growth of new skin to close the wound.
 Artificial skin consists of two layers. The bottom layer, which is designed to
regenerate the lower layer of real skin, is composed of a matrix of inter-
woven bovine collagen( a fibrous cow protein) and a sticky carbohydrate
(sugar) molecule called glycosaminoglycan, which mimics the fibrous pattern
of the bottom layer of skin.
 This matrix then sticks to a temporary upper layer: a medical-grade, flexible
silicone sheet that mimics the top, the epidermal layer of skin.

21. Artificial Cornea
 The cornea is the transparent front portion of the eye that permits light to
enter the eye. Normally crystal clear, it can become cloudy or misshapen,
causing reduction in vision or blindness. The polymers used in artificial cornea
need to be biocompatible, flexible, sufficient mechanical strength.
 The characteristics require for textiles used in the making of the artificial
cornea are to withstand pressure, be transparent, have appropriate
curvature, and have a suitable refractive index, sufficient tensile strength to
allow surgical manipulation and fixation, scratch resistance.

22. Healthcare/Hygiene products
Healthcare and hygiene products are an important sector in the field of medicine
and surgery. They are used either in the operating theatre or on the hospital
ward for the hygiene, care, and safety of staff and patients.

23. Diapers
Baby diapers are used to absorb and retain the body fluids of infants in periods
between birth and 24 months. The technical textile component of the diaper is
the non-woven fabric which prevents fluid leakage and gives the diaper the
desired shape.
 Super absorbent polymer to ensure complete dryness and prevent growth of
bacteria
 The non-woven inner layer should be hydrophilic and absorb fluids fast
 The cover should be breathable
 Optional, leg guards to prevent leakage

24. Sanitary Napkin
A sandwich of an absorbent pad between fabric sheets essentially makes sanitary
napkins. The technical textile component of these napkins is the non-woven
fabric which prevents fluid leakage. The non-woven fabric is made up of 10-20
GSM and accounts for around 11-12% by weight of the sanitary napkin around
0.95 to 1 gram per napkin.
 The super absorbent polymer ensures complete dryness
 Hydrophilic non-woven to absorb fluids fast
 Snug fit
 Breathable cover

25. Surgical Disposables
The surgical disposables primarily consist of masks, capes, drapes, gowns, covers,
and shoe covers made of polypropylene spun-bond fabric (non-woven) with or
without polyethylene film. Surgical disposables are used in hospitals and
pharmaceutical companies to maintain hygienic and sterile operations. These are
called surgical disposables as they are for one-time use and later disposed of.
 High barrier to blood or body fluids
 Lower lint (lint is a source of infection)
 Proven sterilization performance
 Comfort and breathability
 Good bacteria filtration efficiency
 Breathing resistance

26. The global market of medical textile
The global medical textiles market was valued at USD 16,686.6 million in 2019
and is projected to reach USD 23.3 billion at a CAGR of 4.9% by 2025, according
to a new report conducted by Grand View Research, Inc. Now U.S. medical
textiles industry revenue is projected to grow at a rate of 5.3% over the forecast
period.
Also, Germany’s medical textiles was valued for USD 1852.1 million in 2019 and is
projected to grow significantly over the forecast period and the Chinese market
is anticipated to reach USD 1547.4 million by 2025.

27. Opportunity for Bangladesh in the field of medical textiles
Bangladesh is the most populous country in the world with a huge
requirement for healthcare services. The opportunity in the medical textile
industry is also tremendous. Consumption is increasing rapidly. The
healthcare spending from the private sector comprises over 70% of the
market which is more than comparable developing countries as well as
developed countries. The Coronavirus impact has revealed the weakness
and vacuum of medical safety kits all over the world. Here the Bangladeshi
manufacturers can think over it and can take this as an opportunity for the
long run. Regular fashion brands are canceling their orders, at the same
time PPE demand growing sky high all over the world. So, factories can
immediately manufacture this demand-based PPE also can-do plan for
future business. Right now there are a few manufacturers who are
supplying medical accessories to several countries.

28. Medical textile manufacturers in Bangladesh
 Smart Group of Industries
 Nasir & Sons Bangladesh
 E-Baik Transport Corporation
 Abiyan International
 Sagar Trader’s
These manufacturers of Bangladesh supplying regularly their products in many
countries such as the USA, Malaysia, Pakistan, India, Lebanon, Sri Lanka and
Nigeria. There are now many more factories like Snowtex, Urmi Group, Aman
Group, Dekko Group, etc. are producing personal protective equipment (PPE) to
meet the current local demand.

29. Export Figure of Bangladesh’s Medical Textiles in Corona Epidemic
Corona has changed the image of the export of health care products. Mask
exports from March to July amounted to $2.68 core, up from only $26lakh in the
same period last year. On the other hand, PPE, Apron and Surgical gowns exports
have been $35 core 15 lakh. Of that, PPE exports in July and August alone were
USD 13 crore. In the last few months, materials worth USD 50 core 10 lakh have
been shipped to the United States, the United Kingdom, Canada and the
European Union.

30. Conclusion
The importance of medical textiles in human life, healthy living and
improvement is immense. The development of new technologies and new
items will help patients to overcome the hardships that they used to suffer
in the past. But the sad thing is that even though there is research on
Medi-Technology in developed countries, there is not much research in
Bangladesh. There are many more unknown areas of medical textiles, we
should do research on those issues. We should pay more attention to the
production of healthy and quality medical textile materials. In addition to
technology, we need to keep an eye on the price of our products. Through
this it will be possible to produce quality complete and readily available
modern medical textiles.
