摘要

The challenge of any textile company today to position itself in the global market lies in the development of value added products. Nanotechnology is the art and science of manipulating matter at the nanoscale to create new and unique materials and products. This research work attempted synthesis and characterization of titanium dioxide nano particle and their application on woven and knitted fabrics (100% cotton & 45/55% polyester/cotton) for antibacterial activity. The titanium dioxide (TiO2) nano particles were prepared with urea as a reacting medium. These nano particles have an average size of 9 nm, which was confirmed by Transmission Electron Microscope (TEM). 1% of the nano TiO2 were applied on both woven and knitted fabrics. The presence of nano particles on the fabric surface was confirmed by Scanning Electron Microscope (SEM). The nano TiO2 impregnated woven and knitted (100% cotton & 45/55% polyester/cotton) fabrics showed excellent antibacterial activity against two representative bacteria, Staphylococcus aureus (Gram positive) and Klebsiella Pneumoniae (Gram Negative).The antibacterial property of untreated fabrics showed no reductions whereas the titanium dioxide nano particles treated 100% cotton woven shows 85% and 64% reduction, 45/55% polyester/cotton woven shows 93% and 78% reductions, 100% cotton knitted fabrics showed 75% and 58%, and 45/55% polyester/cotton knitted fabrics showed 79% and 74% reductions against Staphylococcus aureus and Klebsiella Pneumoniae bacteria, respectively. Mechanical properties such as tensile strength, elongation, crease recovery, air permeability of nano TiO2 treated fabrics did not change considerably than the untreated fabrics.
