Abstract:
In order to solve the problems of large water consumption, power consumption and wastewater emissions in conventional aqueous dyeing process, anhydrous dyeing engineering production of polyester bobbins was conducted by employing a 1000 L multiple supercritical CO2 fluid dyeing system with independent intellectual property. Based on the developed multiple supercritical CO2 fluid dyeing plant, a dyeing process in supercritical fluid was introduced systematically. Furthermore, the anhydrous dyeing process for polyester bobbins was carried out in supercritical CO2 fluid using a uniquely designed bobbin dyeing kettle. The result show that the dyed polyester bobbins with high color depth and good levelness are obtained by employing the 1000 L multiple supercritical CO2 fluid dyeing plant. In addition, washing colorfastness, the rubbing colorfastness and light colorfastness of the dyed bobbins were rated more than 4-5, 4-5 and 6, respectively.
Key words: dyeing, supercritical carbon dioxide, disperse dye, engineering, polyester bobbins
