Techno-science of some recently introduced nano finishes for
textile substrates has been reviewed. The logic of using low molecular weight
fibre- reactive fluorocarbons that form the basis of Nano-Care™ finish to
impart durable hydrophobic-oleophobic characteristics to fabrics, as described
in a patented literature, has been discussed. Super-hydrophobicity as exhibited
by lotus leaves and the finishes to get self-cleaning textile fabrics based on
the Lotus Effect™ have been covered giving some typical recipes. Mechanisms proposed to explain the photo-catalytic self-cleaning effect of TiO2 have been
described. Developments in the production and evaluation of nano silver and
wound care devices based on antimicrobial activity of silver have been covered
in detail.
