Claims
- 1. A fabric-modifier comprising dimensionally stable gelled sheet consisting essentially of about 15-30% water, about 40-60% of a water-miscible organic solvent selected from the group consisting of a polyethylene glycol, a lower alkanol, a glycol ether, a pyrrolidinone and mixtures thereof, and an amount of a fatty acid salt effective to form a dimensionally gelled stable sheet, having uniformly distributed therein an effective amount of a fabric-modifying agent selected from the group consisting of a quaternary ammonium salt, an imidazolinium salt, a stearyl amine salt, a nonionic surfactant, an amphoteric surfactant and mixtures thereof; wherein said sheet leaves an insignificant residue in a rotary hot air dryer following a laundry drying cycle.
- 2. The fabric modifier of claim 1 wherein the organic solvent comprises a glycol ether.
- 3. The fabric modifier of claim 2 wherein the glycol ether comprises 2-ethanol.
- 4. A fabric modifier comprising a gelled sheet formed by a process comprising:
- (a) forming a uniform liquid dispersion consisting essentially of an effective amount of a fabric-modifying agent selected from the group consisting of a quaternary ammonium salt, an imidazolinium salt, a stearyl amine salt, a nonionic surfactant, an amphoteric surfactant and mixtures thereof, and about 7-20% of a fatty acid salt in about 15-30% water and about 40-60% of a water-miscible organic solvent selected from the group consisting of a polyethylene glycol, a lower alkanol, a glycol ether, a pyrrolidinone and mixtures thereof; and
- (b) forming the dispersion into a dimensionally stable gelled sheet; wherein said sheet leaves an insignificant residue in a rotary hot air dryer following a laundry drying cycle.
- 5. The fabric modifier of claim 4 wherein the dispersion further comprises an effective amount of fragrance.
- 6. The fabric modifier of claim 4 wherein the gelling agent is an alkali metal fatty acid salt which is formed in the dispersion by neutralizing a fatty acid with an alkali metal hydroxide.
- 7. A method for depositing a fabric-modifying agent on fabrics in a rotary hot air dryer comprising placing the fabric modifier of claim 1 or claim 4 in which the dryer with the wet fabrics, and operating the dryer to dry the fabrics.
