摘要：PCT No. PCT/DE96/02174 Sec. 371 Date Jul. 11, 1997 Sec. 102(e) Date Jul. 11,1997 PCT Filed Nov. 12, 1996 PCT Pub. No. WO97/18157 PCT Pub. Date May 22,

1997Described is a surface element (10) which is provided for controlledly transportingmoisture and for the storage of moisture and which has an air-permeable carrier (14)provided with an adsorbent. The surface element (10) also has an absorbent, moisture-storing fleece layer (12), wherein the adsorber carrier (14) and the fleece layer (12) areconnected together in areal relationship by needling (16) to give an air-permeablecomposite material (22; 22'). The needling (16) is oriented from the fleece layer (12)towards the adsorber carrier (14). The fiber barbs (18) of the needling (16) extend fromthe fleece layer (12) to the adsorber carrier (14) and through the adsorber carrier (14).The fiber barbs (18) provide a wick action for the moisture, whereby moisture transportto the fleece layer (12) is optimized. Particularly upon saturation of the fleece layer (12)excess moisture is stored in the adsorbent of the adsorber carrier (14).
