An absorbent articleincluding a blood separating membercapable of separating blood into blood cells and plasma. The blood separating memberpreferably has pores with a diameter of 6 &#x3bc;m or smaller in a proportion of 20% to 90% in a pore size distribution measured in accordance with ASTM F361-86. A nonwoven fabric obtained by calendering a fiber aggregate can be used as the blood separating member.

Absorbent article

A stretch nonwoven fabriccontains inelastic fibers having a varied thickness along the length and elastic fibers. The nonwoven fabricpreferably includes an elastic fiber layerand a substantially inelastic, inelastic fiber layeron at least one side of the elastic fiber layer. The fibers with a varied thickness along the length are contained in the inelastic fiber layer. The nonwoven fabricis conveniently produced by (a) superposing a web containing low-drawn, inelastic fibers having an elongation of 80% to 800% on at least one side of a web containing elastic fibers, (b) subjecting the webs, while in a non-united state, to through-air technique to obtain a fibrous sheet having the webs united together by thermal bonding the fibers at their intersections, and (c) stretching the fibrous sheet in at least one direction to draw the low-drawn inelastic fibers, followed by releasing the sheet from the stretch.
