The development of new functional textiles based on composite materials of natural fibres and nanomaterials have become of increasing interest within both academic and industrial sectors. The inherent properties of their all precursor components can be combined in a synergistic manner to create innovative multifunctional textiles. Wool is a first class textile, keratin the main constituent of wool fibres, is a complex protein comprising amino acids containing amine and sulphur functional groups, which have the potential to bind to nanoparticles. Nanoparticles can be immobilised on wool imparting their functionality such as optical, electronic and anti-microbial to the textiles. Professor James Johnston and his research group have captured the unique opportunity to use nanopalladium entities as novel colourants on wool fibres through their development and use of proprietary chemistry and nanotechnology. By varying the reaction conditions employed, the size of the palladium nanoparticles and the colour of the resultant metal nanopalladium-wool fibres can be controlled providing a range of coloured textiles. Antimicrobial testing of nanopalladium–wool fibres have showed a significant inhibition zone of bacteria around and underneath the fibres. Thus, nanopalladium-wool fibres provide the opportunity to develop new multi-functional textiles ideally suited for application in high end fabrics and fashions, and for applications requiring anti-microbial properties.
