    摘要： The invention pertains to a foam material for absorption of aqueous liquids, a manufacturing method and an advantageous use of such a foam material, and an absorbent disposable article comprising such a foam material. The foam material is hydrophilic and primarily intended for use in absorbent disposable articles such as baby diapers, incontinence protectors and products for feminine hygiene. However, the foam material according to the invention is also suited for use in other absorbent articles, such as in different wiping materials, bandage materials and other similar products. The chemical structure of a surfactant, which is utilized as a combined emulsifying and hydrophilizing agent when manufacturing the foam material according to the invention, makes it possible to retain a sufficient proportion of the foam surfactant in the foam material even after repeated wettings, something which renders the foam material highly, permanently hydrophilic.

    摘要翻译： 本发明涉及用于吸收水性液体的泡沫材料，这种泡沫材料的制造方法和有利用途，以及包含这种泡沫材料的吸收性一次性制品。 泡沫材料是亲水性的，主要用于吸收性一次性制品，例如婴儿尿布，失禁保护剂和用于女性卫生的产品。 然而，根据本发明的泡沫材料也适用于其它吸收制品，例如不同的擦拭材料，绷带材料和其它类似的产品。 当制造根据本发明的泡沫材料时用作组合乳化剂和亲水剂的表面活性剂的化学结构使得即使在反复润湿之后也可以将足够比例的泡沫表面活性剂保留在泡沫材料中， 使泡沫材料具有高度永久的亲水性。

    摘要： An absorbent article comprises a liquid impermeable backsheet and an absorbent core. The backsheet is not overlaid by the core in at least one margin section. The article also comprises at least one ventilation component 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 0.5 kPa is at least 1 mm. The porosity of the ventilation material is >80%. The ratio between the thickness of the ventilation material measured at 5 kPa and the thickness of the ventilation material measured at 0.5 kPa 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.
