Abstract
Abstract The invention relates to textile fibrous structures impregnated with nonionic surface active agents and suitable for cleaning purposes, in which the textile fibrous structures are built up from water-insoluble high polymers with a content of carboxyl groups, which are mostly present in the form of the alkali metal salts or ammonium salts or as salts of organic ammonium bases, and the impregnation comprises at least one nonionic surface-active agent from the group of the alkylene oxide derivatives, the turbidity or cloud point of which lies below 80°C, as well as the method of preparation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A textile fibrous structure impregnated with nonionic surface-active agent and suitable for cleaning purposes comprising a water-insoluble high polymer textile fibrous structure having a content of salt-forming carboxyl groups in such an amount that there is at least 1 mVal of salt-forming carboxyl groups per gram of said structure, and said carboxyl groups being present substantially as a salt selected from the group consisting of an alkali metal salt, an ammonium salt, a salt of an organic ammonium base, and mixtures thereof, said structure containing from 0.05% to 20% of its weight of an impregnant comprising at least one water-soluble nonionic polyalkoxylated surface-active agent having a turbidity point below 80°C.
Claim 2
Dependent Claim
110 words
A textile fibrous structure impregnated with nonionic surface-active agent and suitable for cleaning purposes comprising a water-insoluble high polymer textile fibrous structure having a content of salt-forming carboxyl groups in such an amount that there is at least 1 mVal of salt-forming carboxyl groups per gram of said structure, and said carboxyl groups being present substantially as a salt selected from the group consisting of an alkali metal salt, an ammonium salt, a salt of an organic ammonium base, and mixtures thereof, said structure containing from 0.05% to 20% of its weight of an impregnant comprising at least one water-soluble nonionic polyalkoxylated surface-active agent having a turbidity point below 80°C.
Claim 3
Dependent Claim
26 words
The textile fibrous structure of claim 1, in which the alkoxy units of said water-soluble nonionic polyalkoxylated surface-active agent contain from 2 to 4 carbon atoms.
Claim 4
Dependent Claim
35 words
The textile fibrous structure of claim 1, in which, the proportion of carbon atoms in the hydrocarbon moiety of said agent to the number of alkoxy units in said agent is from 5:1 to 3:2.
Claim 5
Dependent Claim
15 words
The textile fibrous structure of claim 1, in which said agent is a polyethoxylated agent.
Claim 6
Dependent Claim
25 words
The textile fibrous structure of claim 1, in which there are more than 2 mVal of said salt-forming carboxyl groups per gram of said structure.
Claim 7
Dependent Claim
21 words
The textile fibrous structure of claim 1, in which the turbidity point of said nonionic polyalkoxylated surface-active agent lies below 80°C.
Claim 8
Dependent Claim
15 words
The textile fibrous structure of claim 6, in which said turbidity point lies below 50°C.
Claim 9
Dependent Claim
32 words
The textile fibrous structure of claim 1, in which said nonionic polyalkoxylated surface-active agent is an ethoxylated primary fatty alcohol containing 10 to 24 carbon atoms and 2 to 10 ethoxy units.
Claim 10
Dependent Claim
18 words
The textile fibrous structure of claim 8, in which said fatty alcohol contained 12 to 20 carbon atoms.
Claim 11
Dependent Claim
34 words
The textile fibrous structure of claim 1, in which agent is an ethoxylated phenol carrying a straight-chain alkyl substituent containing 6 to 15 carbon atoms, said ethoxylated phenol containing 2 to 10 ethoxy units.
Claim 12
Dependent Claim
18 words
The textile fibrous structure of claim 10, in which said alkyl substituent contains 8 to 12 carbon atoms.
Claim 13
Dependent Claim
21 words
The textile fibrous structure of claim 1, in which said impregnant comprises from 0.5% to 10% by weight of said structure.
Claim 14
Dependent Claim
21 words
