The present invention relates to a method of sourcing orders for groups of products. , over a period of 3 to 4 hours; dissolving the ash obtained in distilled water at a ratio of 1:100 to form a solution, the obtained solution is filtered under vacuum, followed by filtration through milipor or semper filters to produce a filtrate and the filtrate is subjected to boiling evaporation to produce a liquid having a viscosity of 6. The plastic materials from which the molded bodies are manufactured particularly contain metal oxides having particle sizes from 5 to 100 nm at a content of 0. The hangers also have engagement means for temporarily connecting to one another. The liquid-permeable cover sheet has a central zone which is arranged essentially in the crotch portion of the article, and two end zones which are arranged at the end portions of the article, the liquid-permeable cover sheet being more hydrophilic in the central zone than in the end zones. These products may occur in liquid, gaseous or powder form and belong to the family of organic or halogenated organic compounds.
