Problems solved by technology

Although improvements in automatic washing machines and in cleaning agent formulations are steadily being made, as a general rule, conventional home laundering methods consume considerable amounts of water, energy, and time.
Water-based methods are not suitable for some natural fiber fabrics, such as silks, woolens and linens, so that whole classes of garments and fabrics cannot be home laundered, but instead, must be sent out for professional dry cleaning.
The hard spin cycles tend to c...

Abstract

The invention relates to a non-aqueous washing machine, methods of using the machine, methods of washing, and recycling.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The invention relates to a non-aqueous laundering machine, methods of using the machine, methods of washing, drying and reclamation. BACKGROUND OF THE INVENTION [0002] The present invention generally relates to apparati, methods, and chemistries employed in the home for laundering clothing and fabrics. More particularly, it relates to a new and improved method, apparatus, and chemistry for home laundering of a fabric load using a wash liquor comprising a multi-phase mixture of a substantially inert working fluid (IWF) and at least one washing adjuvant. [0003] As used herein, the terms “substantially non-reactive” or “substantially inert” when used to describe a component of a wash liquor or washing fluid, means a non-solvent, non-detersive fluid that under ordinary or normal washing conditions, e.g. at pressures of 0 Pa to 0.5×106 Pa and temperatures of from about 1° C. to about 100° C., does not appreciably react with the fibers of the fabric...
