[0124] Puncture resistance

[0125] The puncture resistance of three different samples (A, B and C) was measured according to ASTM designation D3763-02 and is shown in Table 1.

[0126] tensile strength

[0127] The puncture resistance of three different samples (A, B and C) was measured according to the method given above and is shown in Table 1.

[0128] elasticity

[0129] The elasticity of three different samples (A, B and C) was measured according to the method given above and is shown in Table 1.

[0130] Sample A is an elastic laminate according to WO03 / 047488 with 15 gsm PP spunbond nonwoven on both sides of a 40 gsm elastic film. The spunbond nonwoven used had an elongation at maximum load of 60%, which was less than the elasticity of the laminate. The low puncture resistance of this material means that it falls outside the scope of the present invention.

[0131] Sample B is an elastic laminate with 25 gsm PP / PE spunbond nonwoven on both sides of a 36 gsm elasti...

Abstract

A pant type absorbent article such as a pant diaper, a sanitary pant or incontinence pant, said article having a core region (3) comprising an absorbent core (2) and a chassis region (4) surrounding the core region. The article at least in part of the chassis region comprises a outer coversheet (10) in the form of an elastic laminate (11) having puncture resistance of at least 15N, wherein the laminate is composed of first and second layers of fibrous material (12a, 12b) and an elastic film layer (13) located between said first and second fibrous layers and in which at least one of the layersof fibrous material (12a, 12b) has an elongation at maximum load greater than the elasticity of the elastic laminate (11).

Description

technical field [0001] The present invention relates to a pant-type absorbent article, such as a pant diaper, sanitary pant or incontinence garment, having a core region comprising an absorbent core and a frame region surrounding the core region, said frame region comprising front, rear and waist regions, with the core region at least located in the crotch region of the article, a liquid-impermeable backsheet disposed at least in the core region on the garment-facing side of the absorbent core, and a permeable The liquid topsheet is arranged at least on that side of the absorbent core facing the wearer in the core region. Background technique [0002] An absorbent article having a defined core region and frame region is considered to be a comfortable fit for the wearer. For pant articles like pant diapers, hygiene shorts, or incontinence shorts, it is also desirable that the article be able to be pulled up and down on the wearer's buttocks so that the wearer or caregiver ca...
