These and many more substances are made according to the teachings of DE 601 19 356 T2 used for tissue conditioning and this enclosed with a membrane which prevents the escape of liquids, but not the escape of gases. During operation of a dryer liquid evaporates due to the action of heat and can escape from the membrane casing and thus distribute itself in the dryer and in the laundry contained therein. Disadvantages of this type of laundry equipment are that no large volumes of equipment substances get on the laundry and that not all equipment is suitable for evaporation. For example, microcapsules and cyclodextrins should be distributed as a liquid.

  • Cyclodextrins are cyclic oligosaccharide compounds having a toroidal structure with a central cavity in which apolar organic compounds can be included. Because of this property, they are nowadays used, for example, in air freshener sprays. The cyclodextrin derivatives contained in these products bind the unpleasant odor-causing compounds. At the same time, they also serve as carriers of fragrances.
