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.

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.
