Development and optimization of the dyeing process with sustainable dyes. Towards a greener and UV stable dyed textile

材料未来实验室有兴趣与CTT集团合作，开发一种使用可持续方法的新型细菌染料颜料为纺织品染色的新方法。众所周知，纺织品的湿工艺，如漂白、染色和洗涤，会造成污染，因为在这个过程中使用了大量的水、能源和化学品。天然染料作为一种解决方案，在湿法生产过程中减少对化石燃料和化学品的依赖，引起了人们的极大兴趣。过去，靛蓝染料是从植物中提取的。然而，由于需要大量的土地和水，植物基染料的生产受到限制。MF实验室在生物反应器中生产的细菌基染料可有效替代化石燃料染料，提高纺织湿法工艺的可持续性。与传统的染色方法相比，这种染色方法只需要很少的水或不需要水，而且能耗也会降低。与不同的合作伙伴合作，将对染色产品的弱点进行优化，以在耐磨损、耐洗涤和耐光照方面与传统染色产品的性能相媲美。

Material Future lab is interested in collaborating with CTT Group to develop a new method of dyeingtextiles with a new bacterial dye pigment using sustainable methods. Wet processes in textiles, such asbleaching, dyeing and washing are known to be polluting due to the high amount of water, energy andchemicals used in the process. Natural dyes are of great interest as a solution to reduce the dependenceon fossil fuels and chemicals in the wet process. In the past, indigo dye was extracted from plants forexample. However, plant-based dyes production is limited due to massive land and water requirements.Bacteria-based dye produced in bioreactor by MF lab can be an efficient alternative to fossil fuel dye toimprove the sustainability of textile wet process. The dyeing method will use little or no water and theenergy consumption will be reduced compared to conventional dyeing. Working with various partners,the identified weakness of the dyed product will be optimized to rival the performance of conventionaldyed products in terms of fastness to crocking, washing and light.
