A method for evaluating the permanency of channels in an absorbent core, the method comprising the steps of: - providing an absorbent core (28), optionally in an absorbent article (20), wherein the absorbent layer comprises a least one channel (26), preferably at least two channels, extending in the longitudinal direction; - providing a liquid (40); - pouring the liquid into the absorbent core so that the absorbent core absorbs at least some of the liquid; optionally squeezing of shaking the absorbent core; - cutting the absorbent core in the transversal direction; and - evaluating the presence or absence of channel bonds (27), and if channel bonds are present optionally evaluating the quality of the channel bonds. |
