Industrial Exploitation of Laser-Dyeing Processes for Apparel and Furnishing Textiles Markets

AHRC资助的激光增强生物技术用于纺织品设计（LEBIOTEX, Grant Ref: AH/ j002666 / 1,2012年6月30日至2015年6月29日）项目实现了一种使用CO2激光技术一步染色和图案纺织品表面的方法。这种技术被称为“局部染色”，包括将染料局部涂在纺织品基材表面，然后进行激光照射。染料的扩散和反应发生在激光相互作用点。这项新技术提供了数字设计机会，可以在天然和合成纤维织物（如羊毛、聚酯、尼龙）上实现多色调、多色彩、摄影和精确的线性细节的高水平定制。在织物和成衣上定制着色，包括跨缝，实现了成品的远程、按需、非接触式加工，并提供了除染料以外的化学物质（例如阻燃剂、抗菌剂）的固定潜力，以实现局部表面改性和功能。与传统的纺织品染色和图案工艺相比，该技术具有显著节约能源、水和染料使用的潜力。预染过程提出了另一种生产和分配流程，可能允许对市场需求采取更精确、更迅速的办法，从而可能减少废物库存，并使货物分配更有效。拟议的后续项目的目的是确定和寻求新的机会，在不同的纺织部门内实施和利用预染技术，重点是将预染技术直接应用于服装、时装和室内装饰织物的潜力。这将实现本地化和按需表面着色、三维图案和表面修改，既美观又实用，同时还具有环境和成本效益。强调与四个不同部门的纺织工业合作伙伴直接合作，将大大提高最近LEBIOTEX研究的影响。

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.
