Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an absorbent article having excellent absorbability of an excretory substance including loose passage and hardly causing feces leakage.

SOLUTION: A diaper 1A includes an absorber 4, and a surface sheet 2 disposed on a skin-facing side of the absorber 4. The absorber 4 includes: an absorbent core 40 formed by stacking core-forming materials consisting principally of fiber materials; and a skin-side core wrap sheet 41 that covers the skin-facing side of the absorbent core 40 and consisting principally of a fiber material. The component fibers of a skin-facing-side surface layer of the absorbent core 40 have a larger average interfiber distance and a smaller contact angle with water than those of the skin-side core wrap sheet 41.

【課題】軟便をはじめとする排泄物の吸収性に優れ、便漏れを起こし難い吸収性物品を提供すること。
【解決手段】おむつ1Aは、吸収体4と該吸収体4の肌対向面側に配された表面シート2とを具備し、吸収体4が、繊維材料を主体とするコア形成材料が積繊されてなる吸収性コア40と、吸収性コア40の肌対向面を被覆し繊維材料を主体とする肌側コアラップシート41とを含んで構成されている。吸収性コア40の肌対向面側表層部は、肌側コアラップシート41に比して、構成繊維の平均繊維間距離が大きく且つ構成繊維の水との接触角が小さい。
