The present invention discloses and claims an absorbent article which utilizes an absorbent portion that includes superabsorbent yarn as part of the absorbent portion, such that liquid is wicked to the perimeter or select regions of the absorbent portion, or the perimeter of the absorbent article itself, taking full advantage of either the depth, width, length or combination of dimensions of the absorbent portion, or absorbent article. The superabsorbent yarn can be one or more of several types, including encapsulated yarn, multilayered encapsulated yarn, coated yarn and sliver-formed yarn as long as such yarn includes at least two components, those being a superabsorbent polymer and a second material which promotes distribution of liquid along the yarn length. In alternatives of the invention, such absorbent article utilizing the superabsorbent yarn provides passive visual signals to consumers, of article saturation levels prior to leakage.
