A slow release agent absorbent dressing particularly comprises a wound-contacting layer covered with tapered apertures. The bottom surface of said tapered apertures contacts a wound area to discharge exudate from the wound area and transmit exudate via a guiding layer to an absorbent layer. Said absorbent layer formed of high-molecular polymeric fibers is mixed with a certain concentration of water-soluble agents, such as antiseptic agents, enzymes and growth factor agents, in a suitable amount. After exudate is into the absorbent layer, said polymeric fibers expand forming into the shape of gel to avoid exudate flowing backward to the wound area. Also, a translucent evaporating layer having numerous micro pores for air venting is above the absorbent layer and the peripheral edges are joined together in the form of a sealed structure by heat-sealing to stop side escape of exudate, which is more effective in preventing the wound area from secondary infection.
