We claim the ornamental design for an absorbent strip for incorporation into diaper or sanitary napkin, as shown and described.
FIG. 1 is a perspective view of an absorbent strip for incorporation into diaper or sanitary napkin;
FIG. 2 is a front view of the absorbent strip, the rear view being symmetrical to the front view;
FIG. 3 is a top plan view of the absorbent strip, the bottom view being identical to the top plan view;

FIG. 5 is an enlarged sectional view of the same absorbent strip, taken along lines 5-5 in FIG. 2.
The broken lines showing the outer contour of the absorbent strip in FIGS. 1-5 are for illustrative purposes only and form no part of the claimed design.
