摘要:
An absorbent article having improved fit and comfort. The absorbent core is designed such that fluid is moved substantially from the crotch region to the waist regions. Preferred absorbent covers have an acquisition region, a distribution region, and a storage region.
摘要:
An absorbent article having an ultimate fluid storage region and a fluid distribution region, positioned between the ultimate storage region and the garment oriented surface of the article, in fluid communication with the ultimate fluid storage region, the ultimate fluid storage region includes a material which has: (1) a Capillary Sorption Desorption Capacity at 100 cm (CSDC 100) of at least 10 g/g; (2) a Capillary Sorption Desorption Capacity at 0 cm (CSDC 0) higher than the CSDC 100; (3) a Loosely Bound Liquid Capacity (LBLC); and (4) a Capillary Sorption Desorption Release Height when 50% of the LBLC are released (CSDRH 50) less than 60 cm. Further, the liquid distribution layer material has a Capillary Sorption Absorption Height at 30% of its maximum capacity (CSAH 30) of at least 35 cm. Disuibution material can be foam materials, particularly those derived from high internal phase water-in-oil emulsions.
摘要:
The present invention relates to an absorbent article, such as for use in hygienic applications, which has an ultimate fluid storage region, and a fluid distribution region positioned between the ultimate storage region and the garment oriented surface of the article, which is in fluid communication with the ultimate fluid storage region, whereby the ultimate fluid storage region comprises material which has a Capillary Sorption Desorption Capacity at 100 cm (CSDC 100) of at least 10 g/g. Further, the liquid distribution layer comprises material having a Capillary Sorption Absorption Height at 30% of its maximum capacity (CSAH 30) of at least 25 cm. The total article provides a reduced tendency for rewetting. Particularly suitable distribution material for the present invention can be foam materials, preferably polymeric foam derived from high internal phase water-in-oil emulsions.

The present invention is a liquid transport member with significantly improved liquid handling capability, which has at least one bulk region and a wall region that completely circumscribes said bulk region, and which comprises a membrane port region and an open port region, whereby the bulk region has an average fluid permeability kb which is higher than the average fluid permeability kp of the membrane port region.
摘要:
It is one aspect of the present invention to provide a liquid handling member which combines high liquid suction capability with a high permeability. It is another aspect of the present invention to provide liquid handling member which combines a high liquid suction capability with a fast 80 percent capacity absorption time. The present invention further provides devices for handling body liquids which comprise the liquid handling member of the present invention such as for example baby diapers, training pants, sanitary napkins, adult incontinence devices, bed mats, and the like.
摘要:
The present invention is a liquid transport member with significantly improved liquid handling capability, which has at least one bulk or inner region with a high average permeability, completely circumscribed by a wall region. The wall region further comprises at least one port region with a lower permeability than the inner region, and with a ratio of its permeability to its thickness of at least 10−7 m.

Disclosed are absorbent cores for inclusion in absorbent articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent cores are designed to be relatively narrow in the crotch region of the article, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear regions of the article.The invention particularly relates to an absorbent article comprising an absorbent core wherein the absorbent core has a crotch width when dry and when wet of not more than about 7 cm, and wherein the crotch region of the absorbent core has a capacity of not more than about 40% of the absorbent core's total absorbent capacity.
摘要:
A method of producing absorbent articles, comprising: suspending particles in a gas carrier to form suspended particles; creating a series of pulses from the suspended particles, wherein each pulse in the series of pulses is created by: accumulating at least some of the suspended particles in a pulsing chamber to form accumulated particles on a rotary separator, and releasing at least some of the accumulated particles by rotating the rotary separator to create each pulse; and suctioning each pulse from the series of pulses onto a forming surface for the absorbent articles.
摘要:
The present invention is a method of and an apparatus for creating a pulsed stream of particles in a carrier means, such as air. A pre-metered stream of particles is accumulated in a pulsing chamber of a pulsing means by interrupting the stream of particles by a separator means, which interrupts the flow for a certain portion of the pulse period. The accumulated particles are then removed from the pulsing means by suction, such as by using an ejector. The invention is further directed to a kit or pack of individual absorbent articles which can be produced using the method and the apparatus.
