Abstract:
Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.
