Abstract From the Canadian patent

An improved absorbent unit for a disposable diaper, or the like, wherein a fibrous batt is initially generally rectangularly shaped and is cut, so as to define side flaps which are folded over into overlapping relationship with one another in the central portion of the batt. A quantity of highly liquid-sorbent superabsorbent material is provided in discrete spaced-apart regions between upper and lower fibrous webs of the diaper batt, with a network of densified wicking embossments and at least one integral densified wicking layer provided for promoting efficient wicking and transport of liquid within the absorbent structure.
