A method of conferring soil release properties on woven or knit polyester fabrics comprising the steps of incorporating into the fabric, 0.2-10%, solids basis, by weight based on fiber of an aqueous composition of an addition polymer, which is soluble in an aqueous solution when in salt form, having mer units of one or both of the amine or amine salt units of the formulae: [Figure] wherein R2 and R3 are H or lower alkyl having 1 to 4 carbon atoms, or together form a cycloaliphatic or cycloaromatic ring having up to 6 carbon atoms, and Z is an addition polymer chain, and containing mer units from at least one monoethylenically unsaturated monomer having a group of the formula [Figure] there also being present in the polymer chain pendant －COOH groups in an amount corresponding to a mer ratio in an amount of amine and/or amine salt units: －COOH groups of between 100:1 and 1:1, and drying the polyester fabric. A woven or knit polyester fabric prepared by the method of claim 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11.
