![]() Agricultural waste is taken from a 500 kilometer radius and processed for use as a replacement petroleum raw material. One key development is the company’s EarthColors®, a new range of dyes based on biosynthetic dyes manufactured near Barcelona, Spain. This involves creating efficiencies across the board in wet processing, but also using smart chemistry to change recipes rather than equipment. The “Archroma way” was devised to remove as many toxic impurities as possible from the dyeing process while also making savings on energy and water use. ![]() Removing Toxic ImpuritiesĪrchroma, established in 2013, is a global provider of specialist chemicals, serving the coatings, adhesives and sealants markets, as well as branded and performance textiles. ![]() The products have been adopted by various brands including Primark, which used the dyes in the EarthColors by Archroma loungewear collection - part of its Primark Cares line. Archroma uses agricultural waste- such as almond nut shells, rosemary leaves and bitter oranges - to create its EarthColors® dye range. Let’s look more closely at what each of these companies is doing, in turn. Archroma has created a limited palette of dyes derived from non-edible agricultural and herbal waste, capable of replacing petrol-based raw materials while Colorifix uses microorganisms to grow color based on natural DNA codes -including from plants, animals and insects - that can be applied to textiles without added chemicals.īoth innovations open up a myriad of possibilities for forward-thinking dyehouses that could potentially build elements of more natural dyeing into their existing operations. Both companies make use of natural hues but in very different ways. The first company is Switzerland-based Archroma the second is England-based Colorifix. They are not the only companies blazing a trail in this most fascinating of areas, but they are certainly two to watch, as their processes continue to be developed and refined. Two European companies are under the spotlight in this respect. The 20-page document covers examples of technology and innovation that can cut down on water and energy used in dyeing processes, as well as effluent created.īut it also examines the ways the textile industry can take influence from and harness the help that nature can provide in devising cleaner solutions for coloration. Since its release this past spring, the Society of Dyers and Colourists’ (SDC’s) latest white paper, “Destination low carbon: Global technology and innovation reducing the environmental footprint of textile coloration,” has sparked new conversations about what is possible.
