ORAL We have developed a new proprietary nanotechnology and product suite of high value textiles involving the use of nanogold and nanosilver as colourants and functional components in wool. This innovatively links the high value and prestige of gold and silver with high value textiles and fashion apparel through nanoscience and technology. Gold and silver in bulk form exhibit metallic colours. However, when their particle size is reduced to nano dimensions they exhibit different colours due surface plasmon effects. The colours depend on the size and shape of the nano entities and do not fade like traditional organic dyes. The nanogold and nanosilver entities are formed by the controlled reduction of the Au3+ ion to Au0 and of the Ag+ ion to Ag0 respectively, on the surface and within the wool fibre. An attractive range of colours are available. The products contain only pure wool and pure gold or silver, making them environmentally attractive. Also, nanosilver and nanogold wool exhibit effective anti-microbial properties. This exciting new technology and product suite is a world leading innovation. It offers new business opportunities for the high value fashion apparel, carpets and functional textiles markets where high quality and environmental attractiveness are product hallmarks.
