Abstract
An absorbent core comprises an elongate liquid holding formation with a peripheral edge. The liquid holding formation has a surface formed with at least one channel extending longitudinally in the core for distributing liquid lengthwise along the core. The channel has longitudinally opposite ends spaced longitudinally inward from the peripheral edge of the liquid holding formation to inhibit the flow of liquid in the channels past the peripheral edge of the liquid holding formation.
