Abstract
Abstract A detergent composition, suitable to clean a dyeing machine, comprises (a) a water-soluble or water-dispersible polymer of an unsaturated carboxylic acid monomer or a polymerizable derivative thereof and (b-1) an alkylene oxide adduct of an aliphatic compound or an aromatic compound, (b-2) a sulfonate of a monocyclic compound or a condensed polycyclic compound or (b-3) an aliphatic aldehyde condensate of said sulfonate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
In a method for removing residual dyes and water impurity residues comprising contacting the surfaces of a dyeing machine with a detergent composition, the improvement wherein said detergent composition comprises (a) a water-soluble or water-dispersible polymer of an unsaturated carboxylic acid monomer or a polymerizable derivative thereof and at least one of (b-1) an alkylene oxide adduct of an aliphatic compound or an aromatic compound, (b-2) a sulfonate of a monocyclic compound or a condensed polycyclic compound or (b-3) an aliphatic aldehyde condensate of said sulfonate.
Claim 2
Dependent Claim
86 words
In a method for removing residual dyes and water impurity residues comprising contacting the surfaces of a dyeing machine with a detergent composition, the improvement wherein said detergent composition comprises (a) a water-soluble or water-dispersible polymer of an unsaturated carboxylic acid monomer or a polymerizable derivative thereof and at least one of (b-1) an alkylene oxide adduct of an aliphatic compound or an aromatic compound, (b-2) a sulfonate of a monocyclic compound or a condensed polycyclic compound or (b-3) an aliphatic aldehyde condensate of said sulfonate.
Claim 3
Dependent Claim
20 words
The method of claim 1, wherein said detergent composition comprises (a), (b-1) and one of (b-2) and (b-3) in combination.
Claim 4
Dependent Claim
18 words
The method of claim 1, wherein said polymer (a) is a copolymer of said two or more monomers.
Claim 5
Dependent Claim
29 words
The method of claim 1 wherein said derivative is an alkyl(C1 to C4) ester, an alkali metal salt, an ammonium salt or an organic amine salt of said acid.
Claim 6
Dependent Claim
17 words
The method of claim 1, wherein said polymer is a copolymer of said monomer and another monomer.
Claim 7
Dependent Claim
18 words
The method of claim 1, wherein said polymer an average has a molecular weight of 1,000 to 10,000.
Claim 8
Dependent Claim
25 words
The method fo claim 1, wherein said condensate is an alkali metal salt, an alkaline earth metal salt or an alkanolamine salt, and is water-soluble.
Claim 9
Dependent Claim
43 words
The method of claim 1, wherein said condensate is a formaldehyde condensate of a naphthalenesulfonic acid slat, a formaldehyde condensate of a ligninsulfonic acid salt or a formaldehyde condensate of an alkylnaphthalenesulfonate salt having 1 to 8 carbon atoms in the alkyl group.
Claim 10
Dependent Claim
63 words
The method of claim 1, wherein the weight ratio of (a) to (b-1), (b---2) and/or (b-3) ranges from 1/99 to 99/1, said (a) is contained in an amount of at least 1 percent by weight and the total amount of (a), (b-1), (b-2) and (b-3) ranges from 0.01 to 20 g as a solid per 1 liter of water, the balance being water.
Claim 11
Dependent Claim
46 words
A method as claimed in claim 1 which comprises washing the surfaces of said dyeing machine with an aqueous solution of said detergent composition, said aqueous solution containing from 0.01 to 20 g of said detergent composition, calculated as the solids, per liter of said solution.
Claim 12
Dependent Claim
27 words
A method as claimed in claim 10 in which said aqueous solution consists essentially of (a) plus (b-1), (b-2) and/or (b-3), a reducing agent and an alkali.
Claim 13
Dependent Claim
48 words
A method as claimed in claim 10 in which the walls of said dyeing machine have deposited thereon scales of the residues of a previous dyeing procedure, and wherein said aqueous solution is placed in said dyeing machine and is stirred to remove said scales from said walls.
