WHAT IS NANO TECHNOLOGY?

The term Nano in Nano technology comes from a Greek word “Nanos” which means‘dwarf’. The dictionary meaning of dwarf is abnormally small.One nanometer is one billionth of a meter or 10-9 meters. One Nano meters is about100000 times smaller than the diameter of the human hair.

WHAT IS NANO TECHNOLOGY?

Nano tech is the design characterization production and application structures, devicesand system by controlling shape & size at the nano scale.

This technology that can work at the Molecular level, atom by atom to create largestructures with improved molecular organization.

RECENT APPLICATIONS OF NANO TECHNOLOGY…

High-Performance Ski Wax Breathable Waterproof Ski Jacket Wrinkle-Resistant, Stain-Repellent Garments Deep-Penetrating Skin Cream World’s First OLED Digital Camera Performance Sunglasses Nanocrystalline Sunscreen High-Tech Tennis Rackets and Balls

Luke worm in spite of fast changing fashion cycle.

Technical advancement & Art of finishing Technology quite old.

Fabric & garment finishing basically by covering the texture of the fabric by Resins.

Common problems like Spills ,stains, wear & tear remains unsolved.

Lack of innovation to texturize the fabric on the molecular level.

PRESENT SCENARIO IN TEXTILE FINISHING INNOVATION …

TEXTILE APPLICATIONS OF NANO TECHNOLOGY...

FUNCTIONALwater repellent

FUNCTIONAL PROTECTIONself-cleaning

WhiskersNetWrap

DIFFERENT STRUCTURES OF NANO PARTICLES…

Whiskers

Spine

Hooks

Whiskers

Fiber

The whiskers get hooked on the fibers to alter the fabric property.

NANO WHISKERS CAN MAKE THE FABRIC STAIN & WATER

RESISTANT…

Nano whiskers can keep the fabric breathable too unlike resins finishes!

VALUE ADDITION DUE TO NANO WHISKERS…

• Water and oil repellency

• Superior durability

• Breathable • Fabric remains soft, natural• Wrinkle resistance

Net

Three Dimensional Molecular Nano Net covers the core fiber Completely.

NANO NET CAN INJECT LINEN PROPERTY INTO A SYNTHETIC FIBER

How the original fiber is altered

Absorbency in a polyester!

• Alters the property of synthetic fibers like Polyester to give a feel of cotton & linen.

• Wicks body moisture fast

• Dries quickly & gives the cooling effect.

VALUE ADDITION DUE TO NANO NET…

WRAP

Nano sheet wraps the fiber completely to cover it & alter its property.

NANO WRAPS CAN ENHANCE THE FABRIC LASTING TIME…

Normal fabric trouser with out nano wrap on the fibers after 50 washes!

Trouser made up fabric with nano wrap fibers after 50 washes!

• Strength and Durability.

• Improvement in colorfastness.• Crease retention.• Static resistance.

SOME USEFUL NANO PARTICLES…

Clay Nano Particles:

Composed of various hydrous alumino silicates so possesses various properties like chemical, heat, electrical resistance hence imparts flame retardant anti corrosive finishes to the fabrics.

ZnO Nano Particles:

Can impart UV Shielding in fabrics & can reduce static electricity ofNylon fibers.

THE FUNCTIONAL ASPECTS…

Clay Nano Particles:

ZnO Nano Particles:

TiO2 & MgO Nano Particles:

Photo catalytic activity of TiO2 & MgO particles can break harmful & toxic chemicals and Biological agents hence imparts self-sterilizing function to the fibers. Silver Nano Particles:

Anti microbial & anti mold property of silver particles is utilized to impart anti odor & ultra fresh finishes to the undergarments & socks.

THE FUNCTIONAL ASPECTS

Nano – processed garments have protective coating, which is water and beverage repellent.

Saving time and laundering cost.This technology is environmental friendly.Nano-materials allows good ventilation and

reduces moisture absorption, resulting in enhanced breathability while maintaining the good hand feel of ordinary material.

The crease resistant feature keeps clothing neatGarments stay bright, fresh looking and are more

durable than ordinary materials.Manufacturing cost is low, adding value to the

products.
