Abstract
In order to counteract the electrolyte sensitivity of synthetic thickeners they are used together with natural thickeners. These mixtures are in turn associated with other problems which in many cases can lead to an impairment of the appearance of the goods in dyeings of polyester fibers with disperse dyestuffs. According to the invention these problems can be bypassed if the thickener dispersions, in addition to the thickener mixtures of synthetic and natural products, contain as the continuous phase solvents from the series of the alkyloxypropylates.
