The invention relates to the use of molded bodies as dust-binding means in vacuum cleaners. The molded bodies according to the invention have length/width/height dimensions ranging from 1 mm to 3 cm, at least one dimension being larger than 5.5 mm, and are produced by treating (a) an open-cell foam material having a density ranging from 5 to 500 kg/m3 and a mean pore diameter ranging from 1 µm to 1 mm (b) with an aqueous formulation of at least one compound having at least one hemiaminal group or aminal group per molecule or at least one copolymer which contains at least one OH group- or .beta.-dicarbonyl group- or epoxy group-containing comonomer polymerized into it, (c) and a shaping step.

L'invention concerne l'utilisation de corps moulés dont les dimensions, longueur, largeur, hauteur, sont comprises dans chaque cas entre 1 mm et 3 cm, au moins une dimension étant supérieure à 5,5 mm, obtenus (a) par traitement de la mousse à alvéoles ouvertes dont la masse volumique est comprise entre 5 et 500 kg/m3 et le diamètre moyen des pores est compris entre 1 µm et 1 mm; (b) par mise en contact avec une formulation aqueuse d'au moins un composé avec un groupe semi-aminal ou aminal par molécule ou au moins un copolymère, qui contient au moins un comonomère comprenant des groupes hydroxyles ou des groupes .beta.-dicarboxyliques ou des groupes époxydes; (c) et pour finir par une étape de façonnage pour en faire un agent antipoussière à placer dans des aspirateurs.
