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.
