A Dutch company has unveiled what it believes to be the first commercial dyeing machine to replace water with supercritical carbon dioxide—a pressurized form of the gas with unusual liquid-like properties. Heated up to 31 degrees Celsius (88 degrees Fahrenheit) and pressurized to 74 bar, CO2 takes on the characteristics of both a liquid and a gas, allowing for the dissolution of compounds such as dyes. For DyeCoo Textile System’s purposes, scCO2 is heated to 120 degrees Celsius (248 degrees Fahrenheit) and pressurized to 250 bar. Behaving as both a solvent and a solute, the supercharged carbon dioxide penetrates textile fibers and disperses the preloaded dyes without extra chemical agents.

    How long it will take to commercilize this technique to save our earth from the toxication of water.I want this technology to popularize for use at large to replace the conventional method of dyeing. I belong to a city which is using the water & contaminating the ground water to such a level that it will be of no use for the coming generation. I am proud of you that you have developed soch a technology for dyeing so that the generation will not be ashemed of us. You have done miraculous work by inventing this method of dyeing.
    Thanks a lot

    I am preparing presentations for garment dyeing for a seminar in Mexico. What potential does this have for applying cotton dyes such as reactives, directs or sulfurs and recovering unused dyes?
