Abstract

When used in a washing machine, a particulate detergent packed in portions in a flexible bag of a flat, water-permeable textile material leads to an improved detergency performance and/or saving of detergent by comparison with the conventional addition of detergent via the dispensing compartment of the washing machine if the bag material satisfies certain criteria in regard to the nature of the fibers used for its production and, optionally, the permeability to air and the adsorption capacity of the bag material, the geometric dimensions of the bag and its filling level.
