Title
(EN) Absorptive article and method of producing absorbent element
(ZH) 吸收性物品和吸收单元的制造方法
Abstract
(EN)
To achieve a sufficient antibacterial performance without damaging absorptivity by using filament masses as an absorbent element. [MEANS FOR SOLVING PROBLEMS] A paper diaper having an upper layer absorbent (56A) located in the top sheet (30) side and a lower layer absorbent adjacent to the bottom of the upper layer absorbent as an absorbent element which receives a liquid having permeated through the top sheet (30) in the face to be used, wherein the absorbent element (50) comprises the upper layer absorbent (56A), which has a filament mass made up of a number of filaments (52) continuing along the anteroposterior direction of the article, and a lower layer absorbent element (56B), which has a short fiber mass made up of a number of short fibers (55) gathering at random and antibacterial particles (51) dispersed therein, located adjacent to the upper layer absorbent.
