<p>The invention relates to a foam element (7) made from a foam and particles (11) of at least one hydrophilic substance such as cellulose, superabsorbers. The foam element (7) containing the particles (11) has a reversible capacity to absorb moisture. A part of the particles (11) is completely embedded in the foam. Another part of the particles (11) is disposed protruding out from a surface (13) of the foam, such as cell walls (9) or cell webs (10). The foam without the hydrophilic substance has an absorption capacity of more than 2.8% by weight at an equilibrium moisture corresponding to a temperature of 23° C.</p> |
