“While humans have used water to dye fabrics for more than 2,000 years, today water is an increasingly scarce resource that needs to be conserved.
Ultraphor® KCB represents Archroma’s first entry into the CO2 dyeing field, and the company is looking to introduce further coloration and finishing effects in the future. Tong Siang has extensively tested Ultraphor® and is successfully using it in bulk production, with the resulting products meeting Tong Siang’s customers’ demanding needs related to colour, performance and environmental friendliness. Ultraphor® KCB is a high-quality concentrate manufactured at Archroma’s dedicated OBA plant in Germany, and is proven to be ideally suited for this water free, CO2 dyeing technology.

Archroma’s range of optical brightening agents (OBAs) for polyester – the Ultraphor® series – is a perfect solution to meet this need. With increased scrutiny by consumers and environmentalists alike, textile manufacturers are eagerly seeking new, sustainable dyeing techniques that do not harm the environment. The technology uses 100 per cent pure dyes with more than 98 per cent uptake, and uses no process chemicals and no water, and produces no waste water. The CO2 is reclaimed from existing industrial processes, recycling 95 per cent of it in a closed-loop system. In this state, CO2 has a very high solvent power, allowing the dye to dissolve and be transported easily and deeply into fibres, creating bright whites and vibrant colours. When pressurised, CO2 becomes “supercritical” (SC-CO2), a phase between a liquid and a gas. Textiles produced by Tong Siang, using this technology, are branded as DryDye® fabrics. The technology in question is based on carbon dioxide instead of water, and was developed and patented by Dutch process engineering company DyeCoo Textile Systems B.V. Thailand- based Tong Siang, a member of the Yeh Group, is making these products using what is considered by the industry as the world’s first water-free and process chemical-free dyeing solution. has chosen to use Archroma’s Ultraphor® KCB optical brightening agent to colour its white, highperformance sportswear. Archroma, a global leader in colour and specialty chemicals, recently announced that Tong Siang Co.
