Abstract
A method is disclosed for cleaning textiles using cyclic dimethylsiloxanes as a cleaning fluid for removing soil spots. The useful siloxanes include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane.
Claims9
A method for cleaning textiles which comprises applying a liquid composition consisting essentially of about 100 percent by weight of a cyclic siloxane selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane to a textile soiled with oil, grease or sebum, and removing from the textile a combination comprising cyclic siloxane and oil, grease or sebum.
A method for cleaning textiles which comprises applying to a soiled textile a composition consisting essentially of
- (a) 30 to 70 percent by weight of a cyclic siloxane selected from the group consisting of octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane, and
- (b) 30 to 70 percent by weight of tetrachloroethylene;
- and
- removing from the textile a combination comprising soil, tetrachloroethylene and cyclic siloxane.
A method for cleaning textiles which comprises applying to a soiled textile a composition consisting essentially of
- (a) 30 to 70 percent by weight of octamethylcyclotetrasiloxane, and
- (b) 30 to 70 percent by weight of mineral spirits;
- and
- removing from the textile a combination comprising soil, mineral spirits and cyclic siloxane.
A method for cleaning textiles which comprises applying to a textile soiled with oil, grease or sebum, a composition consisting essentially of
- (a) an absorbent material selected from the group consisting of mineral particulates, organic particulates and synthetic porous polymers, and
- (b) an effective amount to aid soil removal of a solvent component comprising a cyclic siloxane selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane, wherein said absorbent material (a) is used at a level of about 5 to 40 weight percent based on said component (b) and wherein said cyclic siloxane comprises about 100 percent of said solvent component;
- and
- removing from the textile a combination comprising oil, grease or sebum, absorbent material and cyclic siloxane.
A method for cleaning textiles which comprises applying to a textile soiled with oil, grease or sebum, a composition consisting essentially of
- (a) a surfactant selected from the group consisting of anionic, nonionic, zwitterionic and ampholytic surfactants, and
- (b) an effective amount to aid soil removal of a solvent component comprising a cyclic siloxane selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane, wherein said surfactant constitutes from about 10 to 80 weight percent of said composition and said cyclic siloxane comprises about 100 percent of said solvent component;
- and removing from the textile a combination comprising oil, grease or sebum, surfactant and cyclic siloxane.
