Abstract
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.
Highlights
Nano particles have at least one dimension as 100 nm or less
The present study reports observations when 100% polyester (‘p’), 100% cotton (‘c’) and polyester–cotton blended (p–c; 50:50) fabric samples were treated with copper nano sol
Plain woven ‘p’, ‘c’ and p–c blended fabrics were coated with nano sized copper by paddry-cure method
Summary
Nano particles have at least one dimension as 100 nm or less. Owing to higher surface areas nano materials can be highly reactive; find their application in variety of fields like medicine, electronics, food, fuel cells, batteries, water treatment, chemical sensors, pharmaceuticals, dairy industry, textiles etc. Nano application is opted for improving the ultra violet (UV) protection, water repellency, and in odor and moisture management. They have capability to provide self cleaning and anti-bacterial properties making them popular for intimate as well as non intimate applications. In short the type of effect achieved like self cleaning/antibacterial/ UV resistant and so on, is greatly dependent on the choice of nano material selected and Kanade and Patel Fash Text (2017) 4:10 its inherent characteristics (Patel et al 2014; Bhattacharya and Chaudhari 2014; Shaikh et al 2015; Chattopadhyay and Patel 2012)
