Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
A particulate textile fiber or fabric cleaning composition, having a high affinity for textile soil normally resistant to vacuum removal and adapted for distribution without dusting to natural or synthetic textile fibers or fabric and for expeditious removal therefrom, which comprises: (a) from about 5 to 50% by weight of an aqueous volatile solvent in amounts sufficient to control dusting and to provide uniformity in said particulate composition; (b) from about 10 to 95% by weight of an inert, highly absorbent carrier in sufficient amounts to cooperate in removing textile soil and to form a central wetted core; and (c) from about 15 to 90% by weight of a natural or synthetic aluminosilicate zeolite in sufficient amounts to effectively remove textile fiber or fabric soil, said zeolite formulated to become anchored to said central core to resist dusting.
Claim 2
Dependent Claim
138 words
A particulate textile fiber or fabric cleaning composition, having a high affinity for textile soil normally resistant to vacuum removal and adapted for distribution without dusting to natural or synthetic textile fibers or fabric and for expeditious removal therefrom, which comprises: (a) from about 5 to 50% by weight of an aqueous volatile solvent in amounts sufficient to control dusting and to provide uniformity in said particulate composition; (b) from about 10 to 95% by weight of an inert, highly absorbent carrier in sufficient amounts to cooperate in removing textile soil and to form a central wetted core; and (c) from about 15 to 90% by weight of a natural or synthetic aluminosilicate zeolite in sufficient amounts to effectively remove textile fiber or fabric soil, said zeolite formulated to become anchored to said central core to resist dusting.
Claim 3
Dependent Claim
31 words
The composition of claim 1 wherein the volatile solvent is from abut 15-30 percent by weight of deionized water and from 3 to 7% by weight of an organic volatile solvent.
Claim 4
Dependent Claim
34 words
The composition of claim 1 wherein the absorbent carrier is a cellulose or textile fiber from about 100-140 microns in length and employed in amounts from about 25-40 percent by weight of the composition.
Claim 5
Dependent Claim
27 words
The composition of claim 1 in which the zeolite is a synthetic, sodium A zeolite employed in amounts from about 20-50 percent by weight of the composition.
Claim 6
Dependent Claim
17 words
The composition of claim 1 including from about 5 to 15 percent by weight of a brightener.
Claim 7
Dependent Claim
18 words
The composition of claim 1 wherein the textile fiber is in the form of a carpet or rug.
Claim 8
Dependent Claim
16 words
The composition of claim 1 wherein the composition includes from 4 to 30% of a propellent.
Claim 9
Dependent Claim
44 words
A process of cleansing which comprises applying to a textile fiber in the form of a carpet or similar surface, the composition of claim 1, allowing the composition to stand for a time sufficient to cleanse the textile fabric and thereafter, removing said composition.
