Embodiment Construction

[0026] Hereinafter, a tape-type disposable diaper as an embodiment of the absorbent article according to the present invention will be described with reference to the drawings. Such as figure 1 As shown, the belt-type disposable diaper 1 according to the present embodiment includes an absorbent body 12 that absorbs excrement of a wearer and an exterior body 13 that holds the absorbent body 12 at a predetermined position of the wearer. Other examples of absorbent articles include such as Figure 4 Shown are a pant-type disposable diaper, a split-type disposable diaper, and a disposable sanitary short.

[0027] Such as figure 2 As shown, the exterior body 13 includes: an inner layer sheet 131 positioned on the skin side, an outer layer sheet 132 positioned on the non-skin side or outside, and a cellulose-containing fiber sheet 133 arranged between the inner layer sheet 131 and the outer layer sheet 132 . Each of the inner layer sheet 131 and the outer layer sheet 132 is mad...

Abstract

This absorbent article is provided with an absorbent body and an outer body for holding the absorbent body. The outer body comprises one of the structures (A) to (C) described below, and the difference in total light transmittance in the thickness direction when absorbing moisture as opposed to when dry is 5% or more. The color of the outer body according to the Munsell color system satisfies one of (a) to (c) indicated below. Structure (A): a structure provided with an inner layer sheet located on the skin side of a wearer and comprising thermoplastic fibers, an outer layer sheet located on the non-skin side and comprising thermoplastic fibers, and a cellulose fiber-containing sheet arranged between the inner layer sheet and the outer layer sheet. Structure (B): a structure provided with an inner layer sheet located on the skin side of a wearer and comprising thermoplastic fibers, an outer layer sheet located on the non-skin side and comprising thermoplastic fibers, and a cellulose fiber-containing sheet arranged further toward the skin side of the wearer than the inner layer sheet. Structure (C): a structure provided with an inner layer sheet located on the skin side of a wearer and comprising a thermoplastic fiber part and a cellulose fiber part, and an outer layer sheet located on the non-skin side and comprising thermoplastic fibers. (a) The lightness is N 9.0 (white). (b) The hue is R (red), YR (yellow-red), or Y (yellow), the lightness is V8 or less, and the chroma is C3 or higher. (c) The hue is GY (yellow-green), G (green), BG (blue-green), B (blue), PB (purple-blue), P (purple), or RP (red-purple).

Description

technical field [0001] The present invention relates to absorbent articles. Background technique [0002] Absorbent articles such as disposable diapers include an absorbent body that absorbs excrement and an exterior body that holds the absorbent body at a predetermined position of a wearer. The outer body includes a nonwoven sheet mainly formed of hydrophobic fibers in order to prevent leakage of excrement in various situations. However, leakage may occur due to changes in the wearer's posture. Therefore, various disposable diapers having a function of notifying that the diaper is wet due to excrement have been proposed. For example, absorbent bodies comprising pH indicators which change color when urine reaches the surface opposite the wearer's contact side, and absorbent bodies comprising chemicals which change color when wetted with water are known. [0003] There is also proposed a disposable diaper in which a liquid-diffusing fiber sheet for absorbing leaked excreme...
