DISPOSABLE ARTICLE OF WEAR |
摘要 |
A disposable wearing article adapted to prevent indicators from being transferred to a liquid-absorbent structure and to make the indicators develop the color reaction quickly in response to a discharge of body exudates. A disposable diaper 1 has a topsheet 11, a backsheet 12 and a liquid-absorbent structure 20 interposed between these top- and backsheets 11, 12. A surface of a first backsheet 13 facing the liquid-absorbent structure 20 is formed with indicators 15. The indicators 15 contain a hot-melt polymer, an indicator agent adapted to develop a color reaction and a plasticizing oil. The liquid-absorbent structure 20 has a liquid-absorbent core 21, a liquid-diffusive wrapping sheet 22 adapted to wrap the core 21. A hydrophilic bottom sheet 40 is interposed between a bottom surface 21b of the core 21 and a bottom surface region 24 of the wrapping sheet 22. A dimension W1 in the transverse direction X of the bottom sheet 40 is larger than a dimension W2 of a region 15a in which the indicators 15 are formed and smaller than a dimension W3 in the transverse direction X of the core 21. |
