<p>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 transporting moisture 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) are connected together in areal relationship by needling (16) to give an air-permeable composite 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 from the 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 transport to 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).</p> |
