Method of making absorbent core structures with undulations

摘要

A method of making an absorbent core structure includes meltspinning at least one layer of fibrous material. At least one valley is formed separating at least two peaks in substantially parallel rows in the layer of fibrous material. A first portion of the first layer of fibrous material is folded over a second portion of the first layer of fibrous material. A least part of the first layer of fibrous material is densified.
