imogo Dye-Max Digital Spray Dyeing

imogo AB is a Swedish innovation company based in Limhamn that started in 2018 around a new process for dyeing textile materials. It targets the heavy use of water, chemicals and energy in conventional exhaust dyeing such as jet dyeing, which also produces large volumes of wastewater.

Dye-Max applies a low-viscosity dye dispersion to fabric inside a closed chamber through high-performance spray valves, with precision nozzles in removable spray cassettes and the patented Pro Speed valve controlling the applied volume. It works with a liquor ratio below 1 litre per kilo of fabric, can dye one or both sides, handles woven and knit fabric, and in most cases replaces a padder on stenter or continuous dyeing lines. The product family also includes Mini-Max for lab recipe testing, F-Max for spray finishing and B-Max for spray bleaching. Buyers are textile dyehouses and fabric mills.

• Closed-chamber spray dyeing: dye dispersion is sprayed onto fabric in a closed chamber with exhaust and filtration.
• Pro Speed valve: patented valve controls applied volume for precise and repeatable application.
• Removable spray cassettes: tool-free exchange in under a minute with nozzle cleaning for quick colour changes.
• Industrial specifications: fabric widths of 1800, 2200 and 2600 mm at 5 to 50 m/min process speed.
• Line integration: fits stenter lines and most continuous dyeing lines, or runs as spray batch production.
• Product family: Mini-Max lab unit, F-Max spray finishing and B-Max spray bleaching.

Vietnamese knit and woven dyehouses could retrofit Dye-Max onto stenter lines to cut water and wastewater treatment loads. Fabric mills supplying European brands could use spray dyeing and spray finishing to meet buyer water-reduction targets. Mills in industrial zones with wastewater discharge limits could add capacity without enlarging treatment plants.

imogo states that Dye-Max, compared with jet dyeing, cuts water, energy and chemical use by up to 90% each and dye use by up to 30%, with a liquor ratio below 1 litre per kilo of fabric. Spray cassettes can be swapped without tools in under a minute, shortening colour changeovers. The unit can be integrated into existing stenter and continuous lines, limiting new capital investment.

Dyeing and finishing are among the most water- and energy-intensive steps in textile production, and brands are pushing suppliers to cut water, chemicals and emissions. Vietnam's dyehouses face stricter wastewater standards and limited capacity in industrial zones, while brand programmes such as H&M Group's are piloting low-water dyeing with Asian suppliers.

imogo AB was founded in 2018 and is headquartered in Limhamn, Sweden; the former domain imogo.se redirects to imogo.com. Partners shown include ACG Kinna Automatic and the Swedish School of Textiles. In October 2024 H&M Group announced a Dye-Max pilot at its Bangladeshi supplier Chorka Textile, where installation began in September 2025. imogo entered the Turkish market in January 2024.
