The recent emergence of nanotechnology in the marketplace
has raised global concerns among scientists, researchers, regulatory agencies,
consumers and the general public, regarding its safety. It is expected that
nanotechnology will have a major impact on medicine and health care; energy
production and conservation; environmental cleanup and protection; electronics,
computers, and sensors; and world security and defense. Hence the justification
and need for appropriate controls and standards to be adopted and implemented
to protect the public's health.
Nanotechnology is the creation and use of particles one
billionth of a meter for the manufacture of materials, products and devices.
The term Nano in Nanotechnology comes from a Greek word "Nanos" which
means 'dwarf'. The dictionary meaning of dwarf is abnormally small.
The benefits to science and society from Nanotechnology are
substantial. If the criterion is to produce very minute particle size fibers
and materials the nano technology is the only way to achieve the same.This
paper elucidates about the nano finishing in textile. Techno-science recently
introduced some nano finishes for textile substrate has been reviewed here. The
logic of using low molecular weight fiber-reactive fluorocarbons that from the
basics of Nano-Care finish durable hydrophobic characteristic to fabrics. And
mechanisms proposed to explain the photo-catalytic self-cleaning effect of TiO2
have been developed.
