SYNTHESISING METHODS AND APPLICATION OF NANOSILVERS IN ANTIBACTERIAL COATING OF TEXTILES

Nanotechnology defined as the contour and manufacture of materials, devices and systems with control at nanometer dimensions is considered as a concept in which everything in the world is considered from the viewpoint of atomic or molecular building blocks, and is already influencing a very broad range of human technological activity. When a bulk material is reduced to small-size particles with one or more dimension within the nanometer range, the material will show properties that are drastically different from those of the bulk material. Recently, nanosized organic and inorganic particles have drawn increased attention in medical textile applications due to their amenability to biological functionalisation. The nanoscience and nanotechnology make excellent developments in textile science as well as others sciences. The development of new clothing products based on the immobilisation of nanoparticles on textile fibres has recently received a growing interest both from academic and industrial sectors. These products impart unrivalled properties, especially antibacterial activity, to the treated fabrics. In the last few decades there has been growing interest in reducing the availability of commercial textile containing chemical antibacterial agents due to the environmental pollution, poisonous nature, and irritant property; so the new types of safe and commodious biocidal materials need to be replaced with these chemical agents. A wide range of nano-structures such as nanosilvers can be immobilised on fibres, which brings antibacterial properties to the final clothing product. This review introduces the application of nanosilvers in antibacterial coating of textiles in details up to 2008.
