ABSTRACT:
Liquid carbon dioxide, in combination with agitation and, optionally, with process enhancers, such as surfactants, and solvents, such as water, is used to remove contaminants from garments or fabrics. Both apparatus and process are disclosed. Carbon dioxide-cleaned garments are rendered free of odor, require no drying, and the cost per unit solvent (by weight) is a fraction of that of conventional solvents.
