Earthcolors x G-Star Raw: Naturally Dyed Denim

A partnership between Swiss chemicals group Archroma and Dutch fashion brand G-Star Raw has resulted in a capsule collection of naturally dyed denim jeans – an initiative that promotes more sustainable alternatives to synthetic textile dyeing.

Available in green, brown and blue, the jeans are dyed with Archroma’s Earthcolors. These high-performance natural dyes are synthesised from non-edible agricultural or herbal industry plant waste, such as leaves or nutshells. Made using up to 100% natural waste material, the dyes can be used without generating any toxic wastewater. For more on responsible and innovative dye processes, see Considered Colour.

Earthcolors feature seven warm, earthen tones, including a brown made using almond shells and a sandy yellow made using residue from bitter oranges. The dyes are currently suitable for cellulosic fibres such as cotton, viscose and linen, with dyes for other fibres in development.

A rising awareness of the harmful effects of industrial dyeing pollutants is causing brands to consider eco-friendly manufacturing processes. At present, many colours are made using petroleum or sulfur dye, and most blue jeans are dyed with synthetic indigo – processes that damage the environment due to chemicals and pollutants in the wastewater.

Other clothing brands such as Patagonia and Kathmandu have also partnered with Archroma to bring natural, sustainably dyed products to market. See our A/W 19/20 Colour Direction Sacred Earth for more on raw and natural colour.
