Despite efforts to improve the existing processes, textile industry is still considered a major pollutant due to the origin of dyes uses, number of polluting chemicals employed in textile dyeing and use of energy and water. Proposed project tackles challenges cellulose textile dyeing by exploiting the power of enzymes to design sustainable pre-treatment of cellulose fabrics, and by using plant-based flavonoid pigments as a new generation of purely nature-inspired dyes.Cellulose fibres are not only of huge importance for textile industry, but also in biohacking and bioplastic industry, although their processing still involves extensive chemical treatment which often leads to decreased quality and shorter shelf life.We propose use of enzymes to afford purely biological pre-treatment of fibres, which will improve dyeing and longevity of not only virgin but also recycled cellulose materials. Such enzymes together with gycosylated flavonoid (containing sugar within their structure) will be delivered within all-in-one bioengineered systems developed in Colorifx for industrial dyeing. To monitor pigment binding and the quality of industrial process, we will develop optical fibre based spectroscopic system of advanced analysis, which is adaptable to industrial scale.Use of engineered biology tools significantly decreases the usage of water, while use of flavonoids removes the need for synthetic dyes, which pose a significant burden in terms of resource and energy usage, and water and soil pollution. Proposed project aims not only to change the way cellulosic materials are treated and dyed, but will also provide a training platform for researchers to prepare them to take on the leadership roles in R&D and industry, that will result in faster and more efficient transition of global textile manufacturing towards more sustainable, greener processes.

尽管努力改善了现有过程，但由于染料的起源，纺织工业仍然被认为是主要污染物，并且在纺织品染色和能量和水的使用中采用的污染化学物质数量。拟议的项目通过利用酶设计可持续的纤维素织物预处理，并使用基于植物的类黄酮颜料作为新一代纯粹自然风味的染料来应对纤维素纺织品的挑战。纤维素纤维不仅对文本工业和生物型工业范围都非常重要。为了降低质量和较短的保质期。我们建议使用酶纯粹对纤维进行纯生物学预处理，这将不仅可以改善染色和寿命，而且还可以延长纤维化纤维，而且还可以改善纤维纤维的寿命。 这种酶与妇科基化类黄酮（其结构中的含糖）一起在Colorifx开发的用于工业染色的多合一生物工程系统中。为了监视色素结合和工业过程的质量，我们将开发基于光纤的高级分析光谱系统，该系统适应工业规模。使用工程生物学工具的使用大大降低了水的使用，而使用黄酮的使用可以消除对合成染料的需求，从而对资源和能源和能源和能源和水和土壤和水和土壤和水和土壤和土壤和污垢和水和土壤和水资源和土壤有很大的负担。拟议的项目不仅旨在改变纤维素材料的处理和染色方式，而且还将为研究人员提供一个培训平台，使他们准备在研发和行业中担当领导角色，这将导致全球纺织品制造业更快，更有效地过渡到更可持续的绿色，更绿色的过程。
