Industry

---------------------- predicted as the second

industrial evolution in the world

Small thing can create big business


2/32

Nano is the word derived from the Greeklanguage that means drawf and is usedas a prefix in a system of Units denotinga factor of 10-9.1nanometer (nm) equals to 10-9 meters,or the length of one millionth of amillimeter.

Gravity would become less important

Surface tension would become more important

Van der waals attraction would become important

Professor Norio TaniguchiTokyo Science University, Japan

'Nano-technology' is a Production Technology

Top Down Approach

Processing of materials

separation,

consolidation and

deformation of by one atom or one

molecule


6/32

Advantages

Nano-particles have small sizes(1-100 nm) Provide large surface area

Small amount material consumption will

help saving energy and environment The numerous employment opportunities

and splendid production volume for both

service and goods Novel properties improve the quality of

humans life

Nanotechnology

As size approaches to nano scaleelectrons exhibit extraordinary

behavior due to

Strong attractive forcesQuantum effects

High surface-to-Volume ratios

High surfaceto-bulk ratios

Nano-CareThe first technology. Uses

whisker-shaped 10nm

molecules that bind withcotton

Nano-PelNano-Pel is similar to

Nano-Care, for wool andmultiple layer fabrics

Nano-DryCreates a net-like

structure that bonds with

synthetic material, that

wick away perspiration

Nano-TouchIt uses nanofibres to bond

a cotton-like wrap around a

synthetic core. To impart

Cotton finish

WATER REPELLANT FABRIC

The first technology that used whisker

shaped 10 nm molecules of fluorinated

monomer that is co-polymerised with

carboxylic acid oligomer and converted to

anhydride that reacts with the fibre

UV PROTECTIVE CLOTHING

The use of TiO2 nanoparticles (approx. 500nmdiameters) is done for coating textile fibres

These materials absorb light and scatter much

less than larger particles. Also use for sunprotective clothing.

Flame Retardant

Fire resistant polyurethane resin improvesfire resistance

Free of halogens. The polyurethane has a repeating unit whichcontains bisphenol molecular structure withalkyl group at ortho position. Intumescent flame retardant- montmorilonitesynergism in polypropelene- layered silicatenanocomposite

Nanocomposite Coatings

Nanotech-based thin films and coatings are

beginning to replace traditional epoxies andcoatings.

More cost-effective than traditional coatings.

Provide greater protection.

Nano-coatings are invisible and do not alter

the surfaces it protect,

Revolutionary impact on manufacturing of

lenses for microscopes, fabrication tools etc.

The Particle of Nano Silver

Cell

Membrane

This part ofBacteria is broken by

contact with the nano silver

Dyeing Bacteria that contacted

nano silver

surface treated nano silver particles rupture the cell

membrane and chemically kill the micro-organism.

The nano silver particles can be bound with binders like

polyvinyl pyrolidone or microencapsulated in a polymer

like poly(styrene co-maleic anhydride)

A unique high performance nano particle based (Acrylonitile)

binder for pigment printingThe product offers unmatched adhesion to textile substrates. This

property is especially important for production of high quality goodswhere discerning consumers demand ultimate color fastness of thepigment print to rubbing, washing and dry cleaning.

Furthermore, the nano particle size of its core structure also

allows maintaining a very soft handle; property which is highlyunusual for standard latex based pigment printing binders. In light ofrecent demands for ecologically safe products, Sensoprint 101 Liquiddesigned to be environmentally friendly and completely safe to useand apply. APEO and formaldehyde free, It can even be used forpigment printing of kids wear and bed sheets.
