example

[0192] The following are examples of materials of the ventilation material that can be used for the ventilation member according to the present invention.

[0193] Ventilation material A :

[0194]Cushioning fabric consisting of 100% polyester (AirX, article no.5683, 3mm, Tyex)

[0195] M=1.4731g

[0196] ρ fiber =1.37g / cm 3

[0197] A m =25cm 2

[0198] t 0.5kPa =10.79mm

[0199] 1 5kPa =10.30mm

[0200] The porosity and thickness calculated using the aforementioned equations for material A give the following values:

[0201] ε 0.5kPa =.0.96

[0202] t 5kPa / t 0.5kPa =0.95

[0203] ventilation material B :

[0204] Padding fabric consisting of 100% polyester (AirX, article no.5911, 10mm, Tyex)

[0205] M=0.5451g

[0206] ρ fiber =1.37g / cm 3

[0207] A m =25cm 2

[0208] t 0.5kPa =3.06mm

[0209] t 5kPa =2.88mm

[0210] The porosity and thickness calculated for material B using the aforementioned equations give the following values:

[0211] ε...

Abstract

The invention relates to an absorbent article (1) comprising a liquid impermeable backsheet (8) and an absorbent core (9). The backsheet is not overlaid by the core in at least one margin section (1 1, 12, 13). The article comprises also at least one ventilation component (14, 15, 21 ) constituted by a ventilation material. Each ventilation component is positioned overlaying the backsheet and exclusively localized within one or more margin sections. The thickness of the ventilation material measured at 0.5kPa is at least 1 mm. The porosity of the ventilation material is >80%. The ratio between the thickness of the ventilation material measured at 5kPa and the thickness of the ventilation material measured at 0.5kPa is >0.5. Each ventilation component is arranged such that an associated spacing is created between the wearer's skin and the backsheet when the absorbent article is worn.

Description

technical field [0001] The present invention relates to absorbent articles such as diapers, sanitary napkins, incontinence guards or pantiliners, which include one or more ventilation members, each of which is constructed of a ventilation material and is positioned on only one side of the absorbent article. or within multiple boundary sections. Background technique [0002] Many different types of absorbent articles (such as diapers, sanitary napkins, incontinence guards and pantiliners) are known on the market today. The most important function of these absorbent articles is to absorb and contain bodily exudates like urine, feces and menstrual blood. However, the absorbent article also needs to be comfortable for the wearer. [0003] One factor that affects the comfort of an absorbent article is the environment (ie temperature and absolute humidity) within the absorbent article during use. Environments of warmth and relatively high absolute humidity can make the wearer u...
