An absorbent article having a topsheet, a backsheet, and an absorbent memberinterposed between the topsheetand the backsheetis disclosed. The absorbent memberhas a number of compressed partswhich are discrete from one another and concave on the backsheet facing side and/or the topsheet facing side. The compressed part is configured to increase in thickness on absorbing liquid. The compressed part is made up of a thinnest portionand a sloping portion. The sloping portion a gradually changes in thickness to connect to the thinnest portion

Absorbent article

A sheet which gives an absorbent article improved recovery from distortion is disclosed. The sheet has a recovery force of 0.7 cN or more in the cross direction, a compressive strength of 100 cN or less, and a basis weight of 20 g/mor more.

Sheet for absorbent article and absorbent article using the same

An absorbent article which comprises at least a liquid retentive absorbent member and a liquid impermeable antileakage layer, wherein the liquid retentive absorbent member has a bending stiffness of 0.05 to 1.0 gf.multidot.cm along its lateral direction and a compressive modulus of 2.times.10.sup.6 to 1.times.10.sup.8 dyne/cm.sup.2 along its lateral direction.

An absorbent article has a substantially elongated shape and includes a topsheet 2, a backsheet 3, and an absorbent member 4. The topsheet 2 includes a sheet member which has one surface 2a exhibiting hydrophobic properties and another surface 2b exhibiting hydrophilic properties. The one surface of the topsheet is a skin contactable surface, and the other surface faces the absorbent member 4. The backsheet serves as an anti-leakage sheet and is disposed at opposing longitudinal side portions of an upper surface of the absorbent article inwardly from side edges 1a of the absorbent member so that the backsheet forms a pair of hydrophobic areas A. Each of the hydrophobic areas A has a continuous or discontinuous sealed portion 10 formed by sealing the topsheet 2 and the backsheet 3 along each inner edge A' of each hydrophobic areas A. A body fluid retaining portion 20 is provided at a location lying outside of the sealed portion 10 on the skin contactable surface of the absorbent article. The body fluid retaining portion 10 is formed by folding the topsheet 2 so that the hydrophilic surface 2b forms the inside of the fold.

An absorbent article having a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent member interposed between the topsheet and backsheet, and a moisture absorbent material, wherein the amount of moisture absorption per unit area of the absorbent article is not less than 7.2.times.10.sup.-4 g/hr.cm.sup.2, and a total amount of moisture absorption of the absorbent article is not less than 0.10 g/hr in an environment of 35.degree. C./75% RH.
