摘要:
The present invention relates to absorbent articles which provide improved protection against skin overhydration. A particularly preferred embodiment of an absorbent article of the present invention comprises a body contacting surface having a skin care composition thereon that, when at least a portion of the composition is transferred to a wearer's skin by normal body motion or body heat, the material is effective in providing a skin condition benefit and a liquid impermeable, breathable backsheet having a mass vapor transmission rate value (MVTR) of at least about 1300 g/m.sup.2 /24 hr and an absorbent core having a post acquisition collagen rewet method value (PACORM) with a PACORM:MVTR ratio is less than 0.05 mg/(g/m.sup.2 /24 hr).

摘要:
The present invention relates to absorbent structures for disposable absorbent articles containing absorbent hydrogel particles. Particularly, the invention relates to absorbent structures having the absorbent hydrogel particles distributed such that essentially only particles of less than 105 micrometers are distributed in a dusting layer which, in a disposable absorbent article is adjacent the backsheet side of the absorbent article, and particles of 105 micrometers or larger are distributed in a primary layer.
摘要:
Disposable absorbent article such as a feminine hygiene pad, and adult incontinence article or a baby diaper having a minimised tendency for creating negative skin occlusion which might create over-hydration of the skin by exhibiting a low Breathability Value as impacted by the vapour permeability of backsheet materials and the respective areas as covered by such materials.
摘要:
A disposable absorbent article comprising a backsheet, a topsheet, a fluid acquisition/distribution region and at least on fluid storage region, said article having a total product acquisition performance of more than 3.75 ml/sec in the first gush and more than 0.5 ml/sec in the fourth gush and an in bag stack height of less than 9.9 mm, characterized in that said topsheet allows to retain no more them 0.25 g of fluid as measured by the topsheet-on-acquisition-material-wetness test, and that said acquisition/distribution region has a drip capacity of at least 5.0 grams of fluid per gram of material.
摘要:
An absorbent composite structure suitable for absorbing aqueous body fluids is provided which includes a substrate having two surfaces, a plurality of hydrogel-forming polymer particles and a chemical cross-linking agent capable of bonding to both the substrate and the hydrogel-forming particles. In at least a substantial portion of the structure, the majority of the hydrogel-forming polymer particles are connected by the chemical cross-linking agent directly to at least one of the substrate surfaces. The absorbent composite structure can be incorporated into an absorbent article. A method of making the absorbent composite structure is also disclosed.
摘要:
A diaper or other absorbent article may include an absorbent body comprising in sequence from the top (the surface adjacent the wearer's body). An upper assembly (2, 3, 4, 5) comprising an acquisition layer (3) formed of first fibrous material substantially free of superabsorbent material, a superabsorbent layer (5) consisting substantially only of first superabsorbent material having a Gel Layer Permeability value of at least about 4 ml/cm.sup.2 /sec and which is present in an amount of about 20 g/m.sup.2 to 320 g/m.sup.2, a storage assembly (6, 7, 8) that includes second superabsorbent material (7) having an absorption against pressure of at least 15 g/g at 50 g/cm.sup.2 and which comprises an upper storage layer (6) and a lower storage layer (7) containing at least 70% by weight of the total amount of second superabsorbent in the upper and lower storage layers and which has a thickness which is the same as or less than the thickness of the upper storage layer (6).

摘要:
Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a Saline Flow Conductivity (SFC) value of at least about 30.times.10.sup.-7 cm.sup.3 sec/g; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) a basis weight of at least about 10 gsm. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel-continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.
