Nano technology is an upcoming branch where lot of research work is being done
with the intention of improving/changing properties of the materials. In this study
polyester, cotton and polyester-cotton blended fabrics were coated with copper nano
particles by pad-dry-cure technique. The morphology of nano-composite fabrics
characterized using scanning electron microscope reveals that nanoparticles were
dispersed on the fabric samples. The elemental analysis for confirming the presence of
copper in the fabric samples was done using the Fourier transform infrared spectroscopy
and energy dispersive X-ray spectroscopy techniques. The X-ray diffraction analysis
of the fabric samples helped to unveil that incorporation of copper nano particles
increased the d-spacing value in polyester fabric to a greater extent in comparison to
the cotton and polyester-cotton blended fabrics. The nano treated woven fabric samples
were dyed using myrobolan; a natural dye. The samples were evaluated in terms
of colourimetric parameters and colour fastness. The copper nano-sol treatment was
found to improve both K/S and colour fastness.
