In this specification, " retractility " refers to extending in the prescribed direction and releases the property shunk when elongation. Piece does not have retractility (for non-telescoping property) substantially in certain direction and refers to, even if applying pulling force on certain direction to the piece, The piece also hardly extends.For example, for the sample of 15 × width of length 5cm, by the sample tensilon (Tensilon) etc. material pull-test machines stretch in the longitudinal direction, the extension at break degree in sample fracture be 10% with In the case where lower, which does not have retractility substantially in length direction.Wherein, extension at break degree can be by (when fracture The sample length-sample the original length)/(the sample the original length) × 100 calculate.

At the position that can be contacted with the skin of wearer when wearing of diaper 1, configured with the parent that can absorb sweat The absorbing sweat piece 10 of water area.10 main purpose of absorbing sweat piece is the sweat for absorbing the section of wearer, such as Fig. 1, figure in diaper 1 Shown in 2 and Fig. 4, in veutro portion F (veutro chip part 3F) and the respective skin of drosal part R (dorsal sheet member 3R) with respect to surface side, It is configured at (more not shown) by the outer of longitudinal direction X than veutro portion F or drosal part R are divided into two-part imaginary line on longitudinal X Side, that is, waist opening portion side WH position is configured at the position of the skin near wearer of diaper 1 in the allocation position.It inhales Longer shape, specifically rectangle (band-like) on one direction when sweat piece 10 is formed as overlooking, make its length direction with Lateral Y is consistent, and the overall length throughout the respective transverse direction Y of veutro portion F and drosal part R configures.Absorbing sweat piece 10 is along the vertical of absorber 23 It is configured in a manner of overlapping to end 23a.Absorbing sweat piece 10 has away from the relatively near longitudinally outboard end waist opening portion WH 10a and the longitudinal medial end 10b relatively remote away from waist opening portion WH, two longitudinal end 10a, 10b prolong in parallel in the lateral direction y It stretches.The longitudinally outboard end 10a of absorbing sweat piece 10 is located at the longitudinal end 23a than absorber 23 by the position in the outside of longitudinal direction X, inhales The longitudinal medial end 10b of sweat piece 10 is positioned at the longitudinal end 23a than absorber 23 by the position of the inside of longitudinal direction X.

Fig. 5 indicates the section along longitudinal X of an end of longitudinal X of the veutro portion F of diaper 1.Hereinafter, about absorbing sweat Piece 10 is illustrated centered on the veutro portion F of diaper 1 sometimes, unless otherwise indicated, illustrates to be also applied for drosal part R.

As shown in Figure 4 and Figure 5, hydrophobic in the skin side than absorbing sweat piece 10 far from wearer, that is, non-skin with respect to surface side Property and not the hydrophobic flakes 11 of absorption of perspiration configured in a manner of the longitudinal end 23a across absorber 23 from absorber 23 to as The lateral extension 3E of the exterior body 3 (veutro chip part 3F, dorsal sheet member 3R) of stretchable sheet.11 main purpose of hydrophobic flakes is anti- It is only absorbed the body fluid such as the urine of the absorption of body 23 and escapes to external unfavorable condition along absorbing sweat piece 10, in diaper 1 as shown in Figure 1, Figure 2 With shown in Fig. 4, in veutro portion F (veutro chip part 3F) and the respective skin of drosal part R (dorsal sheet member 3R) with respect to surface side, dredge Water piece 11 is configured at (more not shown) by longitudinal than veutro portion F or drosal part R are divided into two-part imaginary line on longitudinal X The outside of X, that is, waist opening portion side WH position is overlappingly configured in the non-skin opposite face of the allocation position and absorbing sweat piece 10. Hydrophobic flakes 11 are formed as plan view shape identical with absorbing sweat piece 10, longer shape on direction when being formed as overlooking, specifically For be rectangle (band-like), keep its length direction consistent with transverse direction Y, throughout the respective transverse direction Y's of veutro portion F and drosal part R Overall length and configure.Hydrophobic flakes 11 are configured in a manner of overlapping along the longitudinal end 23a of absorber 23.Hydrophobic flakes 11 have Away from the relatively near longitudinally outboard end 11a of waist opening portion WH and the longitudinal medial end 11b relatively remote away from waist opening portion WH, Two longitudinal end 11a, 11b are extended parallel in the lateral direction y.The longitudinally outboard end 11a of hydrophobic flakes 11 is located at than absorber 23 Longitudinal end 23a by the position in the outside of longitudinal direction X, the longitudinal medial end 11b of hydrophobic flakes 11 is located at indulging than absorber 23 To end 23a by the position of the inside of longitudinal direction X.

As shown in Figure 4 and Figure 5, the longitudinal medial end 10b of absorbing sweat piece 10 is located at the longitudinal medial end than hydrophobic flakes 11 11b by longitudinal direction X outside, i.e. close to waist opening portion WH position, hydrophobic flakes 11 as shown in Figure 2 vertical view when and 10 innings of absorbing sweat piece Portion's overlapping, and there is the medial extension 11E extended from the longitudinal medial end 10b of absorbing sweat piece 10 to the inside of longitudinal X.

Moreover, as shown in Figure 2 and Figure 5, in diaper 1, if being with region of the absorbing sweat piece 10 on longitudinal X positioned at same position Region A, it sets with the medial extension 11E of hydrophobic flakes 11 in the case where being located at the region of same position on longitudinal X as region B, The elongation stress of region B transverse direction Y compared with the A of region is larger.The elongation stress and diaper 1 of lateral Y tightens degree to wearer Correlation, the elongation stress of lateral Y is bigger be it is tighter.Therefore, the correlation of the elongation stress of lateral Y is region as described above A < region B compared with the region A for configuring absorbing sweat piece 10, is abutted and is not had on longitudinal X with region A in diaper 1 The region B for configuring absorbing sweat piece 10 and being configured with hydrophobic flakes 11 (medial extension 11E) tightens wearer strongly.Elongation stress It is measured by following methods.

The measurement method > of < elongation stress

Diaper 1 is unfolded and is extended to planar, along the straight line parallel with the lateral Y of diaper 1, cuts out above-mentioned area respectively Domain A1, A2, B are as measurement sample.Not only include exterior body 3 when being cut out, but also will include absorbent main body 2 etc. The whole cutting of diaper 1.Use (share) in the both ends (against the inside of side seal portion S) that the length direction (lateral Y) of sample will be measured The chuck of the Tensilon universal testing machine (RTC-1210A) of ORIENTEC corporation is clamped, and makes to measure sample with 300mm/ The speed of min measures the stress of measurement sample at this time in elongated lengthwise.Specifically, setting exterior body 3 Inside dimensions (a pair of of side seal portion S, S using elastomeric element 33 and in the state that the piece 31,32 of exterior body 3 is not shunk it Between length) be 100 (such as 350mm) in the case where, make to measure fabric elongation to the length for being equivalent to 80 (such as 280mm) Afterwards, stress of the tensile load (cN) as measurement sample when it will be made to be contracted to the length for being equivalent to 71 (such as 250mm). The unit that stress, the i.e. respective stress of above-mentioned zone A1, A2, B of measurement sample passes through the length direction (lateral Y) with each region Length converts, and is calculated as mean stress.

Furthermore as the stress of measurement sample (above-mentioned zone A1, A2, B) as described above, it is specified that setting the inside of exterior material body The reasons why restoring force when being equivalent to 71 length when having a size of 100 is because wearing the shorts type diaper as diaper 1 Main child abdominal circumference length and diaper inside dimensions be comparably 71% or so.The length of abdominal circumference described herein is Refer to, the variation of the perimeter of abdominal circumference when considering the postural change of child, the average value for the abdominal circumference that when stance and sitting posture measures.

In diaper 1 with above such structure, veutro portion F and the respective skin of drosal part R with respect to surface side, with The corresponding position of the section of wearer, with ability of sweat absorption absorbing sweat piece 10 be configured at diaper 1 near wearer's The position of skin, in addition, exterior body 3 (the veutro chip part 3F, back side band part as stretchable sheet on transverse direction Y with retractility Part 3R), the skin one than absorber 23 (absorbent main body 2) far from wearer is respectively arranged in veutro portion F and drosal part R Side, therefore, when diaper 1 is worn, by tightening caused by the convergent force as exterior body 3, absorbing sweat piece 10 and skin stickiness are good It abuts well, can quickly absorb the sweat distributed from skin and it is made to evapotranspire.

In addition, in this way, absorbing sweat piece 10 is configured at be capable of position corresponding with the section of wearer as a result, urine The absorbing sweat piece 10 of cloth 1 is configured in a manner of the longitudinal end 23a across absorber 23 as shown in Fig. 2, Fig. 4 and Fig. 5, it is assumed that Do not configure hydrophobic flakes 11 and absorbing sweat piece 10 while directly being contacted with absorbent main body 2 with the longitudinal direction across absorber 23 In the case that the mode of end 23a configures, when the absorbing sweat piece 10 is contacted using the convergent force of exterior body 3 with the skin of wearer When, it is absorbed the body fluid such as the urine of the absorption of body 23 and is possible to flow out from longitudinal end 23a and escape to diaper 1 along absorbing sweat piece 10 Outside.But in diaper 1, hydrophobic flakes 11 are in the opposite face weight that the non-skin opposite face of absorbing sweat piece 10 is with absorbent main body 2 It configures foldedly, and is configured to the exterior body 3 as stretchable sheet in a manner of the longitudinal end 23a across absorber 23 from absorber 23 Lateral extension 3E, even if therefore such as body fluid from longitudinal end 23a flow out, the diffusion of the body fluid of the outflow in the surface direction Also inhibited by hydrophobic flakes 11, the unfavorable condition that the body fluid can be effectively prevent to contact with absorbing sweat piece 10 and flow along it.

Furthermore in diaper 1, the longitudinal medial end 10b of absorbing sweat piece 10 is located at the longitudinal medial end 11b than hydrophobic flakes 11 By the position in the outside of longitudinal X, hydrophobic flakes 11 have prolongs from the longitudinal medial end 10b to the inside that the inside of longitudinal X extends Extending portion 11E, thus the longitudinal end 23a as the absorber 23 in the outflow source of liquid nearby becomes with it is covered by hydrophobic flakes 11 State, therefore can effectively prevent being absorbed leakage caused by the liquid outflow of the absorption of body 23.

In addition, absorbing sweat piece 10 may cause to damage when being close to strongly with the skin of the wearer of diaper 1 to skin, still As described above, the correlation of the elongation stress of the respective transverse direction Y of veutro portion F and drosal part R becomes the area region A < in diaper 1 Domain B, the region A configured with absorbing sweat piece 10 is pressed relatively weakly in skin side as a result, is not configured absorbing sweat piece 10 and is configured with The region B of the medial extension 11E of hydrophobic flakes 11 is pressed strongly relatively in skin side, therefore the absorbing sweat piece 10 and flesh of region A Skin mildly abuts and is not easy to cause to damage to skin, on the other hand, the medial extension 11E and flesh of the hydrophobic flakes 11 of region B Skin is abutted with the intensity of appropriateness, and the liquid flowed out from the longitudinal end 23a of absorber 23 can be effectively prevent to be attached to skin Unfavorable condition.Near the medial extension 11E of the hydrophobic flakes 11 of region B, it is configured with and is located in region A than the hydrophobic flakes 11 Medial extension 11E close to wearer skin position absorbing sweat piece 10, therefore even if region B beam strongly to a certain degree Tightly, the medial extension 11E of the hydrophobic flakes 11 will not be can cause the intensity of damage to abut with skin to skin.

Diaper 1 combines above-mentioned function and effect, and absorbing sweat piece 10 mildly abuts with skin and rapidly absorbs sweat, and not It is also easy to produce and is absorbed the unfavorable condition that the body fluid that body 23 absorbs escapes to outside along absorbing sweat piece 10, can be realized " to skin Mildness ".
