An aqueous dispersion free of fluorochemicals comprising (A) at least one copolymer obtained by polymerization of the following monomers a) at least one fluorine-free (meth)acrylate ester of a C-Calcohol, b) at least one fluorine-free (meth)acrylate ester of a C-Calcohol, c) at least one monomer selected from the group of vinyl chloride and vinylidene chloride, and, optionally, d) at least one monomer selected from the group of 2-hydroxyethyl(meth)acrylate and 3-chloro-2-hydroxyethyl(meth)acrylate, (B) at least one component selected from the group of a paraffin wax, (C) at least one surfactant, and (D) water, wherein the monomers a) and b) of copolymer (A) are distinct, and the copolymer (A) does not contain any polymerized units of styrene or &#x3b1;-methylstyrene, is useful for the finishing of natural and synthetic textile fabrics to endow the said fabrics with excellent water repellent properties.

Fluorine-free aqueous dispersions for the finishing of textile fabrics

Gaseous or volatile substances which are either themselves odor-active or components of odor-active mixtures of substances are applied to fabrics. The amount of these substances adsorbed by the textiles is then determined. It is then determined what amount of these substances is desorbed again by the textiles upon storage. Comparison of the results which are obtained on textiles which had been finished beforehand with textile auxiliaries with the results of non-finished textiles enables statements to be made regarding odor-inhibiting properties of textile auxiliaries.
