  • Patent number: 9611577
    Abstract: The present invention provides a method for cleaning fabric articles which comprises the steps of: washing the fabric articles with a cleaning solvent in a rotatable drum; rotating the drum at a high spin speed for a high spin period of time after the performance of said washing step; and heating the fabric articles for at least a period of time during the performance of said rotating step. During the heating step, at least some of the cleaning solvent is removed from the fabric articles in both liquid and vapor phases. Heating the fabric articles decreases attractive forces between the liquid phase cleaning solvent and the fabric articles, facilitating the separation and hence removal of additional quantities of the cleaning solvent from the fabric articles.
