Systems, methods, and apparatuses for forming a multi-function core for a dressing are described. The multi-function core includes a contact layer configured to be positioned adjacent to a tissue site, a wicking layer adjacent to the contact layer, an ion exchange layer adjacent to the wicking layer, an absorbing layer adjacent to the ion exchange layer, a blocking layer adjacent to the absorbing layer, and an odor-absorbing layer adjacent to the blocking layer. The contact layer, the wicking layer, the ion exchange layer, the absorbing layer, the blocking layer, and the odor-absorbing layer are coextensive and formed from a plurality of fibers disposed in a fibrous web. Methods of manufacturing the multi-function core are also described. 170-. (canceled)71. A method for providing negative-pressure therapy to a tissue site , the method comprising: placing a sealing member over the tissue interface and sealing the sealing member to tissue surrounding the tissue site to form a sealed space;', 'fluidly coupling a negative-pressure source to the sealed space;', a contact layer configured to be positioned adjacent to the tissue interface;', 'a fluid dispersion layer coupled to the contact layer;', 'an ion exchange layer coupled to the fluid dispersion layer;', 'a liquid retention layer coupled to the ion exchange layer;', 'a liquid blocking layer coupled to the liquid retention layer;', 'an odor removal layer coupled to the liquid blocking layer; and, 'positioning a fluid management apparatus between the tissue interface and the sealing member, the fluid management apparatus comprising, 'operating the negative-pressure source to draw fluid from the sealed space through the fluid management apparatus and generate a negative pressure in the sealed space., 'positioning a tissue interface adjacent to the tissue site;'}72. The method of claim 71 , wherein the fluid dispersion layer claim 71 , the ion exchange layer claim 71 , the liquid retention layer claim 71 , the liquid ...
