Abstract

Process for the optical bleaching of fibrous materials, with dispersion bleaches, characterized in that optical bleach baths containing the dispersion bleacher are used in the form of a solution in a colorless organic liquid, which is not miscible with water, whose point of boiling is above 150ºC and in which the optical brighteners, at room temperature, have a minimum solubility of 0.3 g. Per liter. (Machine-translation by Google Translate, not legally binding)
