| Summary: | The present invention generally relates to apparatuses and methods employed in the home for laundering clothing and fabrics. More particularly, it relates to a new and improved method and apparatus for home laundering of a fabric load using a wash liquor comprising a multi-phase mixture of a substantially inert working fluid and at least one washing additive.
Methods and apparatuses for washing fabric loads without water or using water only as a co-solvent are disclosed. One method of non-aqueous clothes washing includes the steps of disposing clothing in a wash container, delivering a wash liquor to the fabric load, the wash liquor comprising a substantially non-reactive, non-aqueous, non-oleophilic, apolar working fluid and at least one washing additive, applying mechanical energy to the clothing and wash liquor for a sufficient amount of time to provide fabric cleaning and, thereafter, substantially removing the wash liquor from the fabric load. The working fluid may be selected from the group consisting of perfluorocarbons, hydrofluoroethers, fluoronated hydrocarbons and fluoroinerts. |
