Claims
- 1. A fabric modifier comprising a 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 glycol ether, a pyrrolidinone, an alkanol and mixtures thereof, and an effective gel-forming amount of an alkali-metal stearate, having uniformly distributed thereon an effective amount of a fabric softening agent selected from the group consisting of a cationic quaternary ammonium salt, an imidazolinium salt, a stearyl amine salt, a tertiary phosphine oxide, a tertiary amine oxide, a nonionic surfactant, an ethoxylated alcohol sulfate, a sodium alkyl sulfate, an alkyl sulfonate, a sodium alkyl benzene sulfonate, a sodium alkyl glyceryl ether sulfonate, a potassium alkyl glyceryl ether sulfonate, an amphoteric tertiary ammonium compound, a zwitterionic quaternary ammonium compound and mixtures thereof; so that an insignificant residue of said sheet remains in a rotary hot air dryer following the 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-[(2-ethoxy)ethoxy]ethanol.
- 4. The fabric modifier of claim 2 wherein the alkali metal stearate is sodium stearate.
- 5. The modifier of claim 1 wherein the fabric softening agent comprises an imidazolinium salt.
- 6. The modifier of claim 5 wherein the fabric softening agent comprises tallow imidazolinium methosulfate.
- 7. The modifier of claim 1 wherein the fabric softening agent comprises a cationic quaternary ammonium salt.
- 8. The modifier of claim 7 wherein the fabric softening agent comprises a [di(C.sub.8 -C.sub.24)alkyl]dimethylammonium salt.
- 9. The modifier of claim 8 wherein the fabric softening agent comprises (dihydrogenated-tallow)dimethyl ammonium methosulfate.
- 10. The modifier of claim 7 wherein the fabric softening agent comprises ditallow diamido methosulfate.
- 11. The modifier of claims 5 or 7 wherein the sheet further comprises a nonionic surfactant.
- 12. The modifier of claim 11 wherein the surfactant comprises a fatty acid amide or a fatty acid alkanolamide.
- 13. The modifier of claim 1 which further comprises fragrance.
- 14. 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 softening agent selected from the group consisting of a cationic quaternary ammonium salt, an imidazolinium salt, a stearyl amine salt, a tertiary phosphine oxide, a tertiary amine oxide, a nonionic surfactant, an ethoxylated alcohol sulfate, a sodium alkyl sulfate, an alkyl sulfonate, a sodium alkyl benzene sulfonate, a sodium alkyl glyceryl ether sulfonate, a potassium alkyl glycerol ether sulfonate, an amphoteric tertiary ammonium compound, a zwitterionic quaternary ammonium compound and mixtures thereof, and about 7-20% of an alkali metal stearate in about 40-60% of a water-miscible organic solvent selected from the group consisting of a glycol ether, a pyrrolidinone, an alkanol and mixtures thereof, and about 15-30% water;
- (b) forming said mixture into a dimensionally-stable gelled sheet; so that an insignificant residue of the sheet remains in a rotary hot air dryer following the drying cycle.
- 15. The fabric modifier of claim 14 wherein the organic solvent is a glycol ether.
- 16. The modifier of claim 14 wherein the dispersion further comprises fragrance.
- 17. The modifier of claim 14 wherein the alkali metal stearate is formed in the dispersion by neutralizing stearic acid with an alkali metal hydroxide.
- 18. The modifier of claim 14 wherein the alkali metal hydroxide is NaOH.
- 19. The modifier of claim 14 wherein the dispersion comprises about 2.5-25% of a quaternary ammonium salt or an imidazolinium salt.
- 20. The modifier of claim 19 wherein the dispersion further comprises about 1-10% of a nonionic surfactant.
- 21. 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 14 in the dryer with the wet fabrics, and operating the dryer to dry the fabrics.
