Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
139 words
A method of producing a random faded effect on cloth or a made-up garment which is in a wet or dry condition comprising the steps: (a) impregnating granules of a coarse, permeable material having a high absorption characteristic with a bleaching agent; (b) placing the impregnated granules and the cloth or garment, said cloth or garment being in a wet or dry condition, together in a rotatable drum; (c) bleaching said cloth or garment in a dry state by dry-tumbling the cloth or garment and the granules together by rotating the drum for a period of time to produce a random faded effect on the cloth or garment; (d) recovering or disposing of the granules following their separation from the randomly faded cloth or garment; and (e) neutralizing any residual bleaching agent held in the cloth or garment .
Claim 2
Independent Claim
139 words
A method of producing a random faded effect on cloth or a made-up garment which is in a wet or dry condition comprising the steps: (a) impregnating granules of a coarse, permeable material having a high absorption characteristic with a bleaching agent; (b) placing the impregnated granules and the cloth or garment, said cloth or garment being in a wet or dry condition, together in a rotatable drum; (c) bleaching said cloth or garment in a dry state by dry-tumbling the cloth or garment and the granules together by rotating the drum for a period of time to produce a random faded effect on the cloth or garment; (d) recovering or disposing of the granules following their separation from the randomly faded cloth or garment; and (e) neutralizing any residual bleaching agent held in the cloth or garment .
Claim 3
Dependent Claim
19 words
Method as in claim 1, wherein the granules are pumice, and the bleaching agent is a hypochlorite in solution.
Claim 4
Dependent Claim
22 words
Method as in claim 1, wherein the granules are a coarse paper-based material, and the bleaching agent is a hypochlorite in solution.
Claim 5
Dependent Claim
127 words
Method as in claim 1, wherein the period of time during which the granules and the cloth or garment are tumbled together is commensurate with the strength and the desired appearance of the faded cloth or garment, and wherein the granules produce a dual fading action that is a mechanical action due to the haphazard and abrasive contact between the coarse surface of the granules and the fibers of the cloth or garment, and a chemical action by reason of the contact between the cloth or garment and the bleaching agent with which the granules are impregnated, the dual fading action creating a visual effect of irregular patches or areas of dissimilar color shading distributed at random over the entire expanse of the treated cloth or garment.
Claim 6
Dependent Claim
26 words
A cloth or garment obtained by the method of claim 1, wherein the cloth or garment has non-uniform, irregular patches or areas of dissimilar color shading.
Claim 7
Independent Claim
103 words
A method of producing a random faded effect on cloth fabric or a made-up garment which is in a wet or dry condition comprising: (a) disposing the fabric or garment which is in said wet or dry condition in a chamber in dry contact with granules of a coarse, permeable material, said granules having been impregnated with a bleaching agent; (b) bleaching said cloth or garment in a dry state by dry-tumbling said fabric or garment and granules together for a period of time sufficient to randomly fade the fabric or garment; and (c) separating the faded fabric or garment from the granules.
Claim 8
Independent Claim
103 words
A method of producing a random faded effect on cloth fabric or a made-up garment which is in a wet or dry condition comprising: (a) disposing the fabric or garment which is in said wet or dry condition in a chamber in dry contact with granules of a coarse, permeable material, said granules having been impregnated with a bleaching agent; (b) bleaching said cloth or garment in a dry state by dry-tumbling said fabric or garment and granules together for a period of time sufficient to randomly fade the fabric or garment; and (c) separating the faded fabric or garment from the granules.
Claim 9
Dependent Claim
18 words
The method of claim 6 further comprising: (d) removing residual bleaching agent contained in the fabric or garment.
Claim 10
Dependent Claim
14 words
The method of claim 7, wherein the removal is effected during a wash cycle.
Claim 11
Dependent Claim
18 words
The method of claim 7, wherein the removal comprises neutralizing said residual bleaching agent with a neutralizing agent.
Claim 12
Dependent Claim
11 words
The method of claim 6, wherein said granules comprise pumice stones.
Claim 13
Dependent Claim
12 words
The method of claim 6, wherein said bleaching agent is a hypochlorite.
Claim 14
Dependent Claim
11 words
The method of claim 11, wherein said hypochlorite is sodium hypochlorite.
Claim 15
Dependent Claim
16 words
The method of claim 6, wherein said fabric or garment is initially in a dry condition.
Claim 16
Dependent Claim
11 words
The faded made-up garmet produced by the method of claim 6.
Claim 17
Dependent Claim
11 words
The method of claim 2, wherein said hypochlorite is sodium hypochlorite.

Claim 19
Dependent Claim
12 words
The method of claim 6, wherein said bleaching agent is a liquid.
Claim 20
Dependent Claim
11 words
The method of claim 11, wherein said hypochlorite is in solution.
