Sustainable denim brand Triarchy has launched its first collection using WTRLSS digital dyeing technology, which the company estimates can reduce water consumption in dyeing and finishing by 99.9% compared with conventional methods. The collection comprises five garments across three colourways, including a photographic cowhide pattern applied to a pair of jeans and a jacket.

Conventional denim production typically involves multiple dyeing and wet-finishing stages, including washing, bleaching, sanding and rinsing. According to Triarchy, these processes can consume approximately 75 litres of water per pair of jeans. WTRLSS instead uses proprietary software and MultiActiv chemistry to digitally bond colour into the fibre in a single pass, without pretreatment or wash-off.

Designed wash effects, including vintage fading and worn-in details, are applied to flat fabric pieces before cutting and sewing. The companies estimate that the process reduces water use from around 75 litres to approximately two tablespoons and cuts energy consumption by up to 90%. Triarchy conducts a final rinse before shipping the garments.

Beyond resource savings, the technology could offer brands greater flexibility in design and production planning. Triarchy co-founder Adam Taubenfligel said the process enables complex patterns and multiple colour effects to be developed on the same fabric, potentially reducing the need to commit to colours months in advance and allowing production to respond more closely to demand.
