Abstract

[Subject] To provide a body fluid absorbent article including a second sheet, which fulfills its own function, while the “sticking”, which would have been caused by the conventional second sheet, is prevented on the account of embossing.

[Means for Solving Problem] A body fluid absorbent article having a face sheet 1, a body fluid permeable member 20 including an assembly of fibers in tows, a body fluid retainable absorbent element AB in this order, and a face-side second sheet 10, which is interposed between the above face sheet 1 and the above body fluid permeable member 20 with such a positional relation that the above face-side second sheet 10 is at least partly superposed on the above body fluid permeable member 20; and embossing is carried out integrally on the above face sheet 1 and the above face-side second sheet 10 while embossing is not carried out on the above body fluid permeable member 20.

Claims

1. A body fluid absorbent article having a face sheet, a body fluid permeable member including an assembly of fibers in tows, and a body fluid retainable absorbent element in this order, comprising

a face-side second sheet, which is interposed between said face sheet and said body fluid permeable member with such a positional relation that said face-side second sheet is at least partly superposed on said body fluid permeable member;

and

said face sheet and said face-side second sheet, on which embossing is carried out integrally, and the above body fluid permeable member, on which embossing is not carried out.

2. A body fluid absorbent article as defined in claim 1, wherein both areas of said face-side second sheet and said fluid permeable member are smaller than the both areas of said face sheet and of said body fluid retainable absorbent element.

3. A body fluid absorbent article as defined in claim 1, wherein the constituent fiber of the assembly of fibers in tows is cellulose acetate fiber.

5. A body fluid absorbent article as defined in claim 2, wherein the constituent fiber of the assembly of fibers in tows is cellulose acetate fiber.

4. A producing method of a body fluid absorbent article having a face sheet, a body fluid permeable member including an assembly of fibers in tows, and a body fluid retainable absorbent element in this order,

wherein said article comprising a face-side second sheet, which is interposed between said face sheet and said body fluid permeable member with such a positional relation that said face-side second sheet is at least partly superposed on said body fluid permeable member, and

said method comprising steps of

carrying out embossing integrally on said face sheet and said face-side second sheet,

on the resultant embossed sheets, placing said body fluid permeable member, and placing said body fluid retainable absorbent element in this order.
