This document discusses various types of medical and biomedical textiles. It begins by defining medical textiles as those used for first aid, clinical, or hygienic purposes like dressings, bandages, and hygiene products. It then defines biomedical textiles as fibrous structures designed for specific biological environments. The document provides examples of both and discusses their properties and applications. It also discusses epidemiology of common skin diseases like ringworm and athlete's foot. The remainder of the document discusses various treatments, fabrics, and technologies used in medical textiles.

5. Biomedical textiles
Biomedical textiles are fibrous
structures designed for use in specific
biological environments, where their
performance depends on
biocompatibility with cells and
biological tissue or fluids.
For example, in tissue engineering,
biocompatible fibrous scaffolds upon
which new tissue is grown for implants.

6. EPIDEMIOLOGY
Present worldwide, tinea pedis and tinea Manus
are the most common derma tophy toses.
The prevalence of tinea pedis is approximately
10 percent, primarily attributable to modern
synthetic footwear, The incidence of tinea
pedis is higher among those using communal
baths, showers, or pools.

7. Foot Fungus
Ringworm
Ringworm is a skin infection caused by a fungus.
Ringworm can affect skin on your body (tinea corporis), scalp
(tinea capitis), groin area (tinea cruris, also called jock itch), or
feet (tinea pedis, also called athlete's foot).
7

8. Types of tinea include
ringworm, athlete's foot and
jock itch. These infections
are usually not serious, but
they can be uncomfortable.
8

9. Symptoms depend on the affected
area of the body:
Ringworm is a red skin rash that
forms a ring around normal-looking
skin.
Athlete's foot causes itching,
burning and cracked skin between
your toes.
Jock itch causes an itchy, burning
rash in your groin area.

10. A research has shown that the 100% micro-
polyester knit fabric treated with chemicals
The outer side of the fabric is water-repellent
(hydrophobic), whereas the inner side is
water-absorbent (hydrophilic). Moisture is
transported efficiently from the inner-side to
the outer-side.

12. Foot fungus can survive
in inanimate objects for
longer time and when
they find favorable
condition [moist and
warm] multiply faster
and cause infection.
12

13. As per the research
statistics nearly 70 % of
the people will have foot
fungus at some point of
time in their life time.
13

14. In some cases, when the the
bacteria enter the skin
thereafter ,it can bring about
necrosis,purification
resulting in bad smell.

16. The cooling effect of perspiration evaporation makes use of the
very large heat of vaporization of water. This heat of
vaporization is 540 calories/gm at the boiling point, but is even
larger, 580 cal/gm, at the normal skin temperature.
16

17. So fungi thrive in warm, moist
areas. Your risk for getting
athlete's foot increases if you:
• Wear closed shoes, especially if they
are plastic-lined
• Keeping feet wet for prolonged periods of
time
• Sweating a lot
• Developing a minor skin or nail injury

20. Fabrics for the care sector
Polyester Plain fabric is used for clothing in the nursing
sector and is a hydrophilic warp knit made from 100%
polyester. The clever combination of polyester filament
yarn on the outer-side and a special yarn on the inner-
side is said to give the fabric the feel of cotton,
excellent moisture transportation properties and make it
very wearable.
Piqué Bioactive fabric , a hydrophilic circular knit made
from 100% polyester, is designed for piqué polo shirts,
is permanently antibacterial and was awarded the 1.0
mark (very good) by the Prüfinstitut Hohenstein for its
wearable properties.

21. Ultra-Fresh Silpure (silver-based antimicrobials for
the textile market) promises ease of application for
protection for optimal performance. Plant trials have
established that antimicrobial performance of Ultra-
Fresh Silpure remains strong after 50 or more washes
is a powerful benefit for consumers of sports and
leisure wear.
By using typical application processes on 100 %
polyester fabrics, bacterial survival was less than
0.1%, even after 50 washes.
21

22. Silpure: uses the
natural ability of silver
to limit the growth of
odor-causing bacteria
in textiles such as
sportswear, intimate
garments, household
and healthcare textiles.

23. SQA
Silicone Quaternary Amine
The purpose of adding
these chemical compounds
on the fabrics are for:
23

24. • Kills Bacteria and inhibit odor
• Permanent antimicrobial capacity
• Not Extracted from the fabric in use
• Maintains its effectiveness over a period of
time
• Non-toxic,
• Not inhibited by sterilization, storage or
handling.
24

25. The Application of SQA onto the
surface of textiles has been
found to inhibit the growth of
microorganisms and to aid in the
control of the bacteria.
25

26. however when such S Q A are
applied to a non-woven substrate it
was found that the substrate was
rendered hydrophobic, thus
aqueous-based fluids, including
normal body fluids, were repelled
by such a coated substrate.

29. Process for dyeing absorbent
microbiocidal fabric
Dyed, absorbent bioactive wettable fabrics are prepared
by mixing together a wettable hydrophilic organosilicone
polymer, a tinctorial amount of a compatible direct dye
and a bioactive silyl quanter nary amine.
The mixture is applied to a non-woven cellulose-
containing substrate
Fabric so produced is useful as an absorbent surgical
drape or dressing to isolate a surgical incision site while
providing an absorbent antimicrobial field.
29

30. Using Organosilicon Amines
The growth of bacteria and fungi are
inhibited by contacting the organisms with
certain organosilicon amines and their
corresponding amine salts.

35. Textile NANOTECHNOLOGY?
Nanotechnology is the technical process of
working on the nano-scale – each nano-
scale molecule is one million times smaller
than a grain of sand. Nanotechnology refers
to not only the small size of the materials
being used, but also how those materials
are engineered to perform specific functions.

44. The addition of silver nano-particles to fabric
fibers or coatings provides antimicrobial and
reduced odor properties.
Silver possesses natural antibacterial qualities
that are strengthened at the nanoscale, thus
giving dress the ability to deactivate many
harmful bacteria and viruses.
The silver infusion also reduces the need to
wash the garment, since it destroys bacteria,
and the small size of the particles prevents
soiling and stains.
