It is an object of the present invention to provide a novel water-absorbing sheet that can meaningfully reduce the return amount even when introduction of a liquid occurs intermittently for several times (particularly, three or more times) under a situation with no load, and the amount of introduction of the liquid becomes large.

Disclosed is a water-absorbing sheet having a first base material, a second base material, and a water-absorbing layer positioned between the first base material and the second base material, wherein the first base material is a water-permeable sheet positioned on a side where a liquid to be absorbed is introduced, the water-absorbing layer has a first particulate water absorbent localized on a side of a surf ace of the first base material, the surface being arranged to face the second base material; and a second particulate water absorbent localized on a side of a surface of the second base material, the surface being arranged to face the first base material, an overall absorption amount of the second particulate water absorbent as represented by the following formula:

CRC g/g+0.44×AAP2.1 kPa g/g

is 48 g/g or more, and a water absorption time determined according to a vortex method is 35 seconds or more.

A disposable absorbent article is provided having an absorbent core located in a chassis and including absorbent particulate polymer material defining at least one cavity. The absorbent core may be substantially cellulose free or comprise a combination of particulate absorbent polymer material and wood pulp. Methods for making such an absorbent core and corresponding disposable absorbent article are also disclosed.

A woodpulp-free urine pad includes from top to bottom a top sheet, a perforated film layer, a core layer and a bottom layer, wherein the perforated film layer is made by perforating the surface of the waterproof material, the core layer comprises an upper adhesive layer, a lower adhesive layer and a water accepting layer which is mad of SAP polymeric particle between the upper and lower adhesive layers. The utility model has a strong ability to prevent liquid infiltration, and it removes away the wood pulp in the core layer to save a large amount of wood and to protect the environment. A production equipment for producing the woodpulp-free urine pad includes a feeding channel which is composed of a plurality of back-up rolls, follow the direction of forward motion of the feeding channel, there is sequentially provided with a material shelf of lower adhesive layers, an adding mechanism of water accepting layers, a material shelf of upper adhesive layers, a material shelf of bottom layers, a material shelf of top sheet and a cutting table, in order to facilitate the production of the woodpulp-free urine pad.

An absorbent article (20, 20′) comprising a topsheet (58), a backsheet (42,60), and an absorbent core (62), and at least one nonwoven-nonwoven adhesive bond other than a core stabilization bond, wherein the adhesive of the adhesive bond has a Toughness of at least 11 MJ/m.sup.3, a Yield Stress of at least 0.7 MPa. The adhesive may further have a storage modulus G′ of at least 7.5 MPa. These are as measured at 37° C. according to the methods described herein. The adhesive comprises at least 5% by weight of the adhesive of a tackifier.

The embodiments disclose an apparatus including a child sanitary napkin including a disposable child sanitary napkin underwear, wherein the child sanitary napkin includes a waterproof non porous outer layer, an adhered superabsorbent polymer layer, an odor absorbing activated charcoal pad layer with a soft cotton covering layer, an imprinted product barcode and an embedded RFID chip for tracking the child via a digital device cellular connection, wherein the child sanitary napkin includes a shape contoured to a female anatomical groin area, wherein the child sanitary napkin includes flared front and rear terminus areas to increase an adhesive bonding area, wherein the child sanitary napkin includes sizes conforming to children's clothing and age sizes, and age appropriate decorative images including stickers to apply to the child sanitary napkin outer surface.

The present disclosure is directed to an absorbent article comprising a liquid pervious topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and an outer cover forming at least part of a garment-facing surface of the absorbent article, the outer cover comprising a three-dimensional substrate, wherein the three-dimensional substrate comprises a first layer and a second layer, and a plurality of protrusions where the first layer is unbonded to the second layer, and wherein the absorbent article has a Qmax-wet of 1300 W/m.sup.2 or less as measured according to Qmax Test.

The present application discloses novel hot-melt adhesive formulations, with excellent processability, even in processes at high line-speed and at a relatively low temperature, the formulations suitable for strongly bonding substrates that have openings, holes, voids or pores, both macroscopic and microscopic ones, like perforated plastic films, both with bidimensional or tridimensional structure; fibrous substrates, both woven and non-woven; porous plastic films, and the like, all mentioned substrates being widely used for the manufacturing of absorbent hygienic articles. The hot-melt formulations include, as their main or even unique constituent, at least one polymer composition formed by two polyolefins, substantially non-stereospecific, as showed by the low value of their crystallization enthalpy at time zero, the polyolefins having average Number Molecular Weights Mn that do not differ for more than about 6,000 g/mole, being the single average Number Molecular Weights of said polyolefins ranging from about 3,000 g/mole and about 30,000 g/mole.
