Abstract
A supercritical CO 2 dry cleaning system is developed in the research center of Supercritical Fluid Technology, Tohoku University. Carbon dioxide becomes supercritical at a temperature of 31° C and a pressure of 7.3 MPa, a condition mild enough to handle clothes. The diffusion characteristics of supercritical CO 2 are close to that of gases, enabling the substance to penetrate to every corner of the fabric. It is observed that the system without a drying step gives less damage as well as better feeling of the fabric after cleaning with supercritical carbon dioxide.
