Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
73 words
An article of manufacture adapted for providing fabric softening within an automatic clothes dryer, said article comprising: (a) a fabric softening amount of a softening composition containing a formic acid salt of a long chain primary amine softener component , said long chain having from about 12 to 22 carbon atoms; and (b) a dispensing means which provides for release of said softening composition within an automatic laundry dryer at dryer operating temperatures.
Claim 2
Dependent Claim
73 words
An article of manufacture adapted for providing fabric softening within an automatic clothes dryer, said article comprising: (a) a fabric softening amount of a softening composition containing a formic acid salt of a long chain primary amine softener component , said long chain having from about 12 to 22 carbon atoms; and (b) a dispensing means which provides for release of said softening composition within an automatic laundry dryer at dryer operating temperatures.
Claim 3
Dependent Claim
23 words
An article according to claim 1 wherein the long chain group on the primary amine has from about 16 to 22 carbon atoms.
Claim 4
Dependent Claim
41 words
An article according to claim 1 wherein the softening composition contains from about 50% to 100% by weight of the formic acid salt material and additionally contains another softener/antistat agent comprising from about 0% to 5% by weight of the composition.
Claim 5
Dependent Claim
17 words
An article according to claim 3 wherein the additional softener/antistat agent is ditallow dimethyl ammonium methyl sulfate.
Claim 6
Dependent Claim
26 words
An article according to claim 3 wherein the additional softener/antistat agent is sorbitan monostearate or a mixture of sorbitan monostearate and ditallow dimethyl ammonium methyl sulfate.
Claim 7
Dependent Claim
25 words
An article according to claim 1 wherein the dispensing means comprises a flexible substrate in a sheet configuration having the softening composition releasably affixed thereto.
Claim 8
Dependent Claim
48 words
An article according to claim 6 wherein the flexible substrate has an absorbent capacity of from about 2 to 25 and wherein the softening composition is impregnated into the substrate to provide a weight ratio of softening composition to dry substrate ranging from about 10:1 to about 0.5:1
Claim 9
Dependent Claim
33 words
An article according to claim 7 wherein the substrate is a woven or nonwoven cellulosic, polyester or polyester/cellulosic cloth or paper and has an absorbent capacity of from about 2 to about 15.
Claim 10
Dependent Claim
25 words
An article according to claim 7 wherein the substrate is a foamed plastic sheet having an absorbent capacity of from about 15 to about 25.
Claim 11
Dependent Claim
14 words
An article according to claim 1 wherein the dispensing means is an aerosol device.
Claim 12
Independent Claim
64 words
A method for imparting a softening and antistatic effect to fabrics in an automatic laundry dryer comprising commingling pieces of damp fabrics by tumbling said fabrics under heat in an automatic clothes dryer with an effective amount of a fabric softening composition comprising a formic acid salt of a long chain primary amine, said long chain having from about 12 to 22 carbon atoms.
Claim 13
Independent Claim
64 words
A method for imparting a softening and antistatic effect to fabrics in an automatic laundry dryer comprising commingling pieces of damp fabrics by tumbling said fabrics under heat in an automatic clothes dryer with an effective amount of a fabric softening composition comprising a formic acid salt of a long chain primary amine, said long chain having from about 12 to 22 carbon atoms.
Claim 14
Dependent Claim
22 words
The method of claim 11 wherein the long chain group on the primary amine has from about 16 to 22 carbon atoms.
Claim 15
Dependent Claim
35 words
The method of claim 11 wherein the softening composition contains from about 50% to about 100% of the formic acid salt and additionally contains from about 0% to about 50% of another fabric softener/antistat agent.
Claim 16
Dependent Claim
17 words
The method of claim 13 wherein the additional fabric softener/antistat agent is ditallow dimethyl ammonium methyl sulfate.
Claim 17
Dependent Claim
25 words
The method of claim 13 wherein the additional fabric softener/antistat is sorbitan monostearate or a mixture of sorbitan monostearate and ditallow dimethyl ammonium methyl sulfate.
Claim 18
Dependent Claim
25 words
The method of claim 11 wherein the composition is dispensed within the dryer from a flexible substrate sheet having the softener composition releasably affixed thereto.
Claim 19
Dependent Claim
55 words
The method of claim 16 wherein the dispensing means comprises a flexible substrate in sheet configuration having an absorbent capacity of from about 2 to about 25 and wherein the softening composition is impregnated into the substrate to provide a weight ratio of softening composition to dry substrate ranging from about 10:1 to about 0.5:1.
Claim 20
Dependent Claim
32 words
The method of claim 17 wherein the substrate is a woven or nonwoven cellulosic, polyester or polyester/cellulosic cloth or paper and has an absorbent capacity of from about 2 to about 15.
Claim 21
Dependent Claim
24 words
The method of claim 17 wherein the substrate is a foamed plastic sheet having an absorbent capacity of from about 15 to about 25.
Claim 22
Dependent Claim
19 words
The method of claim 11 wherein the softener/antistat composition is dispensed into the dryer from an aerosol dispensing device.
Claim 23
Independent Claim
69 words
A method for imparting a softening and antistatic effect to fabrics during the rinse cycle of an automatic clothes washer comprising adding to the washer at the start of the rinse cycle a flexible substrate having an effective amount of a fabric softening composition comprising a formic acid salt of a long chain primary amine releasably attached thereto, said long chain having from about 12 to 22 carbon atoms.
