Definitions
- the present invention provides a breathable absorbent article such as a sanitary napkin, an incontinence pad and particularly a panty liner for use in an undergarment.
- the absorbent article has a breathable backsheet which comprises a garment facing surface. On the garment facing surface is an adhesive to adhere the article to the undergarment.
- the article may optionally comprise protective side-flaps which during use are folded around the side edges in the crotch region of the undergarment so as to improve soiling protection for the undergarment.
- the absorbent article also comprises the other typical components of such articles namely an absorbent core and a liquid pervious wearer facing surface which is preferably provided by a liquid pervious topsheet.
- the absorbent article comprises a breathable backsheet which usually provides the garment facing surface of the absorbent article. If topsheet and backsheet are present the absorbent core is enclosed by them on the wearer and on the garment side respectively.
- the absorbent article as a whole needs to provide exceptional flexibility.
- the flexibility is measured by the modified ASTM method D1388 as described herein below in longitudinal direction.
- the expression “flexibility” is also referred to as “drapability” due to the particular method. It should be understood that stiffness is characteristic of the opposite behaviour of a material.
- the flexibility should be in the range of 1300 to 5000, preferably from 2000 to 3500, most preferably 2000 to 3000, mg x cm.
- the inner layer comprises a hydrophobic gas-permeable micro- or macro-apertured, polymeric film, it preferably has a directional liquid transport phenomena.
- the film has a first and a second liquid transport direction which are opposite to each other.
- the first liquid transport direction is from the outer layer towards the absorbent core. Liquid transport in the first direction is larger than liquid transport in the second direction when measured under an identical pressure drop across the apertured film.
- Figure 2 shows the garment facing surface of a sanitary napkin having protective side flaps according to an alternative embodiment of the present invention.
- pantyliners pantyliners. It is however equally well applicable to sanitary napkins or adult incontinence articles which are worn in an undergarment and are joint to the undergarment during wearing of the absorbent article .
- Absorbent articles according to the present invention comprise typically three main components: a liquid pervious topsheet, a breathable backsheet and an absorbent core.
- the absorbent core is enclosed by the backsheet and the topsheet and the article is worn such that the exposed surface of the topsheet faces the wearer of the absorbent article while the exposed surface of the backsheet faces the undergarment to which the article is joint by a panty-fastening attachment means.
- this is an adhesive but could also be a mechanical attachment.
- the storage layer comprises from about 15 to 100% absorbent gelling materials and from 0 to about 85% carrier.
- the storage layer comprises from about 30 to 100 %, most preferably from about 60 to 100% absorbent gelling materials and from 0 to about 70 %, most preferably from 0 to about 40 %, carrier.
- the apertures in the macroscopically expanded apertured film of the inner layer are larger than about 0.5 mm. It is also possible to have combinations of micro-apertures and macro-apertures. For leakage prevention reasons it is however preferred to have more micro-apertures than macro-apertures.
- the minimum hydraulic diameter of the apertures in the film should be as small as possible while still providing sufficient gas permeability without hydraulic blockage of the apertures.
- a hydraulic diameter of as little as 2 to 5 micro meter for micro- apertures and up to 700 micro meters for larger apertures has been found possible in the context of the present invention.
- Hydraulic diameter for non circular apertures is the diameter that a circular aperture with the same cross section would have. Diameter is always determined in the plane of smallest cross section of an aperture.
- the layers of the breathable backsheet are not joined to each other in the area coextensive with the absorbent core.
- Particularly inner and outer layers can be thermally laminated or soldered to each other in only some spots for integrity reasons but remain unattached across at least 50% of the area coextensive with the absorbent core.
- the flexibility test is only one way of measuring a sample's flexibility and is believed to be one of the components which users of absorbent articles often refer to as softness. This measurement method should be followed as closely as possible and should not be confused with the multidirectional flexibility described in US 5,009,653. Even so testing of samples in only the longitudinal direction is described and necessary for the present invention it is also possible for very wide or exceptionally flexible articles to measure flexibility in the transverse direction. In general, a single sample strip should be tested only one time. The two sides of the sample should be tested on different sample strips. Likewise, sample strips for use in this test must be very carefully handled to prevent folds, wrinkles, bends, etc. This test is intended to be used on articles before they have been folded or bent for packaging by the manufacturer.
