ABSORBENT ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/102744
Kind Code:
A1
Abstract:
[Problem] To provide an absorbent article that includes a top sheet which has an excellent irregular-shape maintaining property and in which decrease in absorption rate does not tend to occur. [Solution] This problem is solved by an absorbent article which includes a non-woven fabric top sheet (22) that has multiple dome-shaped projections (31) arranged projecting on the obverse surface with the spaces between adjacent projections (31) being grooves (32). The absorbent article is characterized in that through holes (80) that pass through the top sheet (22) in the thickness (22t) direction are formed spaced circumferentially of the projections (31), circumferential edges (81) of the through holes (80) are high-density parts where constituent fibers of the non-woven fabric were pushed from locations becoming the through holes (80) toward the circumferences of the through holes (80), portions of the circumferential edges of the projections (31) are formed of portions of the circumferential edges (81) of the through holes (80), and the portion of the top sheet (22) excluding the circumferential edges (81) of the through holes (80) has a difference between the maximum and minimum values of the apparent thickness (22t) that is 0 to 50% of the maximum value.
