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.

Material Future 实验室有兴趣与 CTT 集团合作，开发一种使用可持续方法用新型细菌染料对纺织品进行染色的新方法。众所周知，纺织品的湿法加工（例如漂白、染色和洗涤）会产生污染，因为该过程中使用了大量的水、能源和化学品。天然染料作为一种减少湿法工艺中对化石燃料和化学品依赖的解决方案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，由于大量的土地和水资源需求，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以成为化石燃料染料的有效替代品，以提高纺织湿法工艺的可持续性。与传统染色相比，该染色方法将使用很少的水或不使用水，并且能源消耗将减少。与各个合作伙伴合作，染色产品的已知弱点将得到优化，以在耐摩擦、耐洗和耐光牢度方面与传统染色产品的性能相媲美。
