Development of SAGES dyes for commercial applications on cellulose applications.

该项目是SAGES和克兰菲尔德大学的合作项目。该项目的重点是测试和开发三种不同的方法，用于纤维素染色工艺的预处理阶段。SAGES是一家纺织行业的初创企业，从食物垃圾中提取天然染料。这些染料是一种天然的，循环的解决方案，工业上目前使用的有害合成染料。本项目选择了5种染料颜色进行进一步开发：粉红色、黄色、蓝色、绿色、深紫色。_**合成染料的问题 **_虽然染料自古以来就为人类所知，但直到十九世纪后期才开始制造合成形式，引发了一系列人类健康问题，包括膀胱癌的高发病率，\[Christie，2007\]以及皮炎和中枢神经系统紊乱等疾病\[Khan & Malik，时装业现在是世界上第二大污染行业，“80%的总排放量”是由染色过程中产生的液体废物引起的[Lellis，2019]。有毒化学品和重金属被用作预处理，使废水难以有效净化。这在中国、孟加拉国、泰国和印度尼西亚等仍然主导染色行业的国家是一个主要问题。天然纺织染料如茜草根和靛蓝似乎是一个明显的解决方案，但由于它们的颜色不一致，而且容易褪色，因此很少在商业上使用。此外，他们需要农田，否则可以用于粮食，种植他们所需的原材料。SAGES染料解决了这些问题，存在于染色行业通过创造天然染料：1.产生最少甚至没有液体废物2。是充满活力和抗褪色3.使用环保的固色剂和提取方法4.将食物垃圾作为资源

This project is a collaboration between SAGES and Cranfield University. The project focuses testing and developing three different methods for the pre-treatment stage of the cellulose dyeing process.SAGES is a textiles industry start up making natural dyes from food waste. These dyes are a natural, circular solution to the harmful synthetic dyes the industry currently uses. 5 dye colours have been selected for further development in this project Pink, Yellow, Blue, Green, Dark Purple._**The problem of synthetic dyes**_Although dyes have been known to mankind since ancient times , it was not until the late nineteenth century that synthetic forms began to be manufactured, causing a range of human health issues including high incidence of bladder cancer, \[Christie, 2007\] and diseases such as dermatitis and disorders of the central nervous system \[Khan & Malik,2018\].The Fashion Industry is now the second most polluting industry in the world and '80% of the total emissions' are caused by the liquid waste created during the dyeing process \[Lellis,2019\]. Toxic chemicals and heavy metals are used as pre-treatments and make it difficult for waste effluent to be effectively cleaned. This is a major problem in countries which still dominate the dyeing industry like China, Bangladesh, Thailand and Indonesia.Natural textile dyes such as madder root and indigo can seem to be an obvious solution however these are rarely used commercially due to their inconsistencies in colour, and tendency to fade. In addition, they require farmland which could otherwise be used for food, to grow the raw materials they require.SAGES dyes solve these problems that exist within the dyeing industry by creating natural dyes that:1. Create minimal to no liquid waste2. Are vibrant and resistant to fading3. Use an environmentally friendly fixing agent and extraction methods4. Use food waste as a resource
