5. NANOTECHNOLOGY
The study of control of matter on
atomic and molecular level
Involves engineering on a small scale
to create smaller, cheaper, lighter and
faster devices that can do more things
with less raw materials.
Nano-scale has generally been taken
to lie from 0.2nm (atom) to 100nm.

6. DIFFERENT
STRUCTURES OF NANO
PARTICLES

7. NANOFIBRES
Nano-fibres are generally taken to be
fibres with a diameter less than 1μm
(100nm).
Electrospinning is the major fibre
production method used to make nano-
fibres.
By manipulation of the electro-spinning
conditions, micro-filaments can be
produced

9. NANOFIBRES
Nano-fibres produced from synthetic fibre
materials can be formed with a high
surface area to volume ratio and small
pores sizes in fabric form.

10. USES OF NANO FIBERSUSES OF NANO FIBERS
The potential end uses for such
nano-fibres are in
filtration,
wound dressings,
tissue engineering,
nano-composites,
drug delivery devices
sensors.

11. NANO-COMPOSITES
FIBRES
Nano-composite fibres consist of
nano-fibres.
The particles may be spheres, fibrils
and by varying the amounts, their
alignment, and distribution within
the nano-fibre improvements in the
mechanical, electrical, optical or
biological properties may be
obtained.

13. CARBON NANO-TUBES
• The carbon nano-tubes
essentially consist of tiny
shells of graphite rolled up
into cylinders, either as
single tubes or multiple
tubes joined together.

14. Carbon Nano-tubes
The carbon nano-tubes
exhibit remarkable
properties:
tensile strength
thermalconductivity
Electrical conductivity

15. Nano-coated fibres
• Nano-coating of textile
fabrics, complete
finished garments or
shoes can be obtained by
plasma polymer
treatment.

27. FUTURE PROSPECTS
The main trust in nano-technologies
applied to
textiles, clothing and footwear will
be to:
Improve the properties and
performance of existing
materials;
Develop smart and intelligent
textiles with novel functions;

28. Greatly increase the use of fibres in technical
textiles, biomedical and healthcare options;
Open up new opportunities for fibres as
sensors.

29. NANO-TECHNOLOGIES
OFFER GREAT POTENTIAL FOR THE FUTURE
AND COULD RADICALLY CHANGE CONSUMER
PERCEPTION OF WHAT CONSTITUTES A
“STANDARD” APPAREL FABRIC.
