Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 107 words
An article of manufacture especially adapted for conditioning fabrics, comprising: a. an effective amount of a clay mixture selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay at a weight ratio of hydrophobic Laponite clay of from about 20:1 to about 1:20; said clay mixture being in releasable combination with; b. a water-insoluble dispensing means.
Claim 2
Dependent Claim 107 words
An article of manufacture especially adapted for conditioning fabrics, comprising: a. an effective amount of a clay mixture selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay at a weight ratio of hydrophobic Laponite clay of from about 20:1 to about 1:20; said clay mixture being in releasable combination with; b. a water-insoluble dispensing means.
Claim 3
Dependent Claim 31 words
An article according to claim 1 wherein the clay mixture comprises hydrophilic Laponite clay and smectite clay at a weight ratio of hydrophilic Laponite: smectite from about 1:10 to about 1:1.
Claim 4
Dependent Claim 30 words
An article according to claim 1 wherein the clay mixture hydrophilic Laponite and hydrophobic Laponite at a weight ratio of hydrophilic Laponite: hydrophobic Laponite from about 1:10 to about 1:1.
Claim 5
Dependent Claim 27 words
An article according to claim 1 wherein the clay mixture is in the form of an aqueous gel and wherein the dispensing means is a perforated pouch.
Claim 6
Dependent Claim 30 words
An article according to claim 1 wherein the clay mixture is in a substantially dry state and wherein the dispensing means is a paper or woven or non-woven cloth sheet.
Claim 7
Dependent Claim 19 words
An article according to claim 1, comprising, as an additional component, an effective amount of an organic fabric conditioner.
Claim 8
Dependent Claim 23 words
An article according to claim 6 wherein the organic fabric conditioner is a fatty-based material selected from quaternary ammonium salts and sorbitan esters.
Claim 9
Dependent Claim 93 words
A process for conditioning fabrics comprising applying thereto an effective amount of a clay mixture selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay, at a weight ratio of hydrophobic Laponite to smectite clay of from about 20:1 to about 1:20.
Claim 10
Dependent Claim 93 words
A process for conditioning fabrics comprising applying thereto an effective amount of a clay mixture selected from: mixtures of hydrophilic Laponite clay and hydrophobic Laponite clay, at a weight ratio of hydrophilic Laponite to hydrophobic Laponite of from about 20:1 to about 1:20; mixtures of hydrophilic Laponite clay and smectite clay, at a weight ratio of hydrophilic Laponite to smectite of from about 20:1 to about 1:20; and mixtures of hydrophobic Laponite clay and smectite clay, at a weight ratio of hydrophobic Laponite to smectite clay of from about 20:1 to about 1:20.
Claim 11
Dependent Claim 26 words
A process according to claim 8 which is carried out by tumbling damp fabrics in a clothes dryer with an effective amount of the clay mixture.
