A polymer compound according to the invention comprises an acrylic acid copolymer composed of acrylic acid derivatives and/or methacrylic acid derivatives, containing: a) at least one acrylic acid derivative and/or methacrylic acid derivative substituted with a sulfonic acid group； b) at least one hydrophilically substituted acrylic acid derivative and/or methacrylic acid derivative； c) at least one lipophilically substituted acrylic acid derivative and/or methacrylic acid derivative； and d) at least one acrylic acid derivative and/or methacrylic acid derivative which acts as a crosslinking agent. In the method according to the invention for loading textile products with a low-molecular compound, a) a textile product is provided with a finishing layer whose accessible surface has a negative charge； and b) the textile product is brought together with an emulsion or active substance solution, for example by immersing the textile product in the emulsion/solution, or by spraying the emulsion/solution on the textile product. At least one low-molecular compound is contained in the dispersed phase of the emulsion, and the surface of the particles of the dispersed phase has a positive charge.
