ABSORBENT ARTICLE WITH ACTIVATABLE MATERIAL

Material webs suitable for use in conjunction with disposable absorbent articles are disclosed herein. The material webs comprise a melt additive that when subjected to thermal energy may be encouraged to bloom across the entirety of the web or in localized areas of the web where localized thermal energy is applied.

Absorbent article

An objective is to provide an absorbent article that can prevent backflow and can reduce water retention in a front sheet as much as possible. In an incontinence pad 1 for use with a medium or larger volume that absorbs 20 cc or a larger volume of urine, a front sheet 3 is formed by coating a water repellent on a spunlace nonwoven fabric that is made of 100 wt. % of cotton fiber. On a skin facing surface side, in a plan view, recess part lines 20, 21 of a diamond-shaped lattice pattern are formed from many first recess part lines 20 that go along a predetermined inclination angle direction and are formed with a constant gap in the pad longitudinal direction and many second recess part lines 21 that go along the inclination angle direction obtained by reversing the first recess part lines 20 in a width direction by the pad longitudinal direction and are formed with a constant gap in the pad longitudinal direction, partition areas 22 of a diamond-shaped lattice shape partitioned by these recess part lines 20, 21 are arranged adjacently in the longitudinal direction and the width direction. Furthermore, many open holes 10 penetrating through both sides are formed at least at an excretion hole corresponding part H.
