The AHRC funded Laser Enhanced Biotechnology for Textile Design (LEBIOTEX, Grant Ref: AH/J002666/1, 30 June 2012 to 29 June 2015) project resulted in the realisation of a method for dyeing and patterning textile surfaces in one step using CO2 laser technology. This technique is termed 'peri-dyeing' and involves applying dye locally to the surface of a textile substrate followed by laser irradiation. The dye diffusion and reaction takes place at the point of laser interaction. The novel technique offers digital design opportunities allowing multi-tonal, multi-colour, photographic and precise linear details with high levels of customisation on both natural and synthetic fibre fabrics (e.g. wool, polyester, nylon). Customised colouration on both fabric and assembled garments, including across seams, enables remote, on-demand, non-contact processing of finished products and offers the potential for fixation of chemicals other than dye (e.g. fire retardants, anti-bacterial) to achieve localised surface modification and functionality. The technique has the potential to make significant savings in energy, water and dye use in comparison with conventional textile colouration and patterning processes. The peri-dyeing process suggests alternative manufacturing and distribution flows that may allow for a more precise, responsive approach to market demands potentially reducing waste stock and enabling a more efficient distribution of goods. The aim of the proposed follow-on project is to identify and pursue new opportunities to implement and exploit the peri-dyeing technique within different textile sectors, focusing on the potential to apply peri-dyeing directly to garments, fashion and upholstery fabrics. This will enable localised and on-demand surface colouration, three-dimensional patterning and surface modification for both aesthetic appearance and functionality, alongside environmental and cost benefits. The emphasis on working directly with textile industry partners in four different sectors will significantly enhance the impact of the recent LEBIOTEX research.
