Archroma, a global leader in colour and specialty chemicals, recently announced that Tong Siang Co. Ltd. has chosen to use Archroma’s Ultraphor® KCB optical brightening agent to colour its white, high-performance sportswear. 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. 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. Textiles produced by Tong Siang, using this technology, are branded as DryDye® fabrics.
