NANOTECHNOLOGYThe 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.
DIFFERENT STRUCTURES OF NANO PARTICLES
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

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.
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 devicessensors.
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.
NANO-COMPOSITES FIBRES
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.
Carbon Nano-tubes
The carbon nano-tubes exhibit remarkable properties:
tensile strength thermalconductivity
Electrical conductivity
Nano-coated fibres
• Nano-coating of textile fabrics, complete finished garments or shoes can be obtained by plasma polymer treatment.

FUTURE PROSPECTSThe main trust in nano-technologies applied totextiles, clothing and footwear will be to:
Improve the properties and performance of existing materials;Develop smart and intelligent textiles with novel functions;
Greatly increase the use of fibres in technical
textiles, biomedical and healthcare options;
Open up new opportunities for fibres as sensors.
