Abstract

The recent emergence of nanotechnology in the marketplacehas raised global concerns among scientists, researchers, regulatory agencies,consumers and the general public, regarding its safety. It is expected thatnanotechnology will have a major impact on medicine and health care; energyproduction and conservation; environmental cleanup and protection; electronics,computers, and sensors; and world security and defense. Hence the justificationand need for appropriate controls and standards to be adopted and implementedto protect the public's health.

Nanotechnology is the creation and use of particles onebillionth of a meter for the manufacture of materials, products and devices.The term Nano in Nanotechnology comes from a Greek word "Nanos" whichmeans 'dwarf'. The dictionary meaning of dwarf is abnormally small.

The benefits to science and society from Nanotechnology aresubstantial. If the criterion is to produce very minute particle size fibersand materials the nano technology is the only way to achieve the same.Thispaper elucidates about the nano finishing in textile. Techno-science recentlyintroduced some nano finishes for textile substrate has been reviewed here. Thelogic of using low molecular weight fiber-reactive fluorocarbons that from thebasics of Nano-Care finish durable hydrophobic characteristic to fabrics. Andmechanisms proposed to explain the photo-catalytic self-cleaning effect of TiO2have been developed.
