Abstract

Provided is an absorbent article, wherein the surface sheet, which contains non-heat-meltable fibers, does not peel off easily. The sanitary napkin (1) comprises: a surface sheet (20); a back sheet (30); a body fluid absorbent (40) that is positioned between the surface and back sheets (20, 30); a heat-meltable sheet (50) that is positioned between the surface sheet (20) and the absorbent (40); and a pair of side sheets (60) that are positioned on the skin-facing surface of the surface sheet (20). The heat-meltable sheet (50) and the side sheets (60) are formed using synthetic fiber that contains thermoplastic resin. The surface sheet (20) is formed using cotton fiber, which is a natural fiber. Multiple openings (21), which penetrate in the thickness direction thereof, are formed. The side sheets (60) are attached so as to overlap and cover the two side edges (20a) of the surface sheet (20). Adhesive sections (71) are formed between the surface sheet (20) and the side sheets (60). Welded sections (72) resulting from heating and pressurization are formed between the side sheets (60) and the heat-meltable sheet (50). Portions of the adhesive sections (71) and the welded sections (72) overlap each other.

Description

technical field [0001] The present invention relates to absorbent articles, and more specifically, to absorbent articles such as sanitary napkins, pantiliners, diapers, and disposable diapers having a top sheet containing natural fibers. Background technique [0002] Conventionally, a sanitary napkin is known as an absorbent article including a top sheet, a back sheet, and an absorbent body sandwiched between the top sheet and the back sheet. For example, Patent Document 1 discloses a sanitary napkin comprising: a top sheet formed of cotton fibers; a back sheet formed of synthetic resin; an absorbent body composed of fluffy pulp or rigid pulp; Hot-melt adhesive fibrous sheet between body and surface sheet. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2009-148328 (JP2009-148328A) [0005] In the absorbent article described in the aforementioned Patent Document 1, the back sheet and the top sheet are joined by an adhesive on the ou...
