Abstract
The invention relates to textile fibrous structures suitable for cleaning purposes and impregnated with surface-active agents, in which the textile fibrous structures are built up from water-insoluble high polymers with a content of carboxyl groups able to form salts, which are present substantially as free carboxyl groups, and the impregnation consists of at least one non-ionic surface-active agent from the group of water-soluble alkylene oxide derivatives, the turbidity or cloud point of which lies above 20.degree.C, as well as the method of production.
