Description :
Nanofabrics are textiles engineered with small particles that give ordinary materials
advantageous properties such as super hydrophobicity, lotus effect, odour and moisture
elimination, increased elasticity & strength and bacterial resistance Depending on the
desired property a nanofabric is either constructed from nanoscopicfibres called
nanofibres or it is formed by applying a solution containing nanoparticles to a regular
fabric. Application of nanofabrics have the potential to revolutionize textile
manufacturing. Nanotechnology is a part of science of technology about the control of
matter on the atomic and molecular scale this means things that are about 100
nanometers or smaller. It includes making products that use parts very small, such as
electronic devices. catalysts, and sensors etc. Nanotechnology is defined as the study of
structures between 1 nanometer and 100 nanometers. A fibre that has a width of less
than 1000 nanometers (1000 mm or 1 um) is generally defined as a nanofibre.
Nanoparticles on the nanoscale have a very high surface area to volume ratio where as
this ratio is much lower for objects on the macroscopic scale. A high relative surface
area means that a large proportion of a particle’s mass exists on its surface which
create many special properties exhibited by nano fabrics. Nonotechnology has nano
materials which can be classified into one, two and three dimensions nano-particles.
This classification is based upon different properties it holds such as scattering of light
absorbing X-ray transport electric current or heat. The aim of the present study is to
see the role of nano technology especially in Textile Processing. The experiments were
carried out. The selected sample was treated for scouring, Bleaching, Peach- finishdyeing,
Pre-testing, Nanofinishing and Post testing. The results revealed that the tear
strength was found to be very good. While tearing strength was decreased and the pH
content was good, &a absorbency was about 5 to 6. So it was concluded that the
nanofinished fabric was good in all aspects compared with conventional fabric.
Key Words :
Textile processing - Nanofabric – Nanofinishing, Hydrophobicity.
