Abstract
Abstract The disclosure relates to fabric-stiffening compositions comprising a fabric-stiffening agent (such as starch), an organic solvent with high penetrating ability, and an emulsifiable wax. These compositions may also contain additional components, such as a water-soluble polyalkylene glycol, a salt of a water-soluble amine and a fatty acid, or a silicone. These compositions can also be pressurized.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
15 words
A composition as defined by claim 1 wherein said propellant is emulsified in said composition.
Claim 2
Dependent Claim
193 words
A process for stiffening fabric, which process comprises spraying onto said fabric a composition comprising an aqueous dispersion of (A) from about 0.5 percent to about 6 percent, by weight, of at least one waterdispersible starch; (B) from about 0.5 percent to about 10 percent, by weight, of at least one isoparaffinic hydrocarbon solvent which has a boiling point from about 240* to about 410*F., high penetrating ability, is substantially immiscible in water, and is emulsified in said composition; (C) from about 0.1 percent to about 5 percent, by weight, of at least one predominantly hydrocarbon aliphatic emulsifiable water-insoluble wax selected from the group consisting of carnauba, palm, candelilla, sugar cane, japan, esparato, fir bark, beeswax, spermaceti, Chinese insect, shellac, polyethylene, copolymers of ethylene and propylene, and copolymers of ethylene and acrylic acid waxes; (D) from about 0.2 percent to about 3 percent, by weight, of at least one salt of a watersoluble amine and a fatty acid having from about 12 to about 22 carbon atoms; and (E) from about 0.1 percent to about 2 percent, by weight, of a water-soluble polyalkylene glycol having two to three carbon atoms per alkylene group.
Claim 3
Dependent Claim
15 words
A process as defined by claim 3 wherein said solvent is emulsified in said composition.
