摘要： A unitary sanitary disposable absorbent incontinence pad has an elongated absorbent member between a pervious cover topsheet and an impervious backsheet. The absorbent member includes an absorbent batt which contains a combination of cellulose fibers and thermally-bondable fibers. A melt-blown web is superimposed on the batt. A portion of each lateral side of the batt is slit and turned inwardly toward the center of the batt to form a pair of fluid-barriers or dams, creating a fluid channel therebetween. The melt-blown web lies between the dams on top of the batt. Preferably the melt-blown web includes inturned side edges which may create a second channel therebetween. The assembly of batt and web are particularly effective for moving fluid longitudinally in said pad and preventing leakage along the sides of the pad.

摘要： An absorbent disposable sanitary product such as a disposable baby diaper has an absorbent core and a multi-ply body-contacting topsheet. The construction of the diaper reduces raw material consumption and also waste at the source of manufacture and, therefore, is environmentally attractive. One of the plys of the topsheet contacts the body but not the core, and another contacts the absorbent core, as well as the body, with a space between the plys. The body-contacting ply has a plurality of upstanding cuffs which improve fecal containment, and the space between the plys reduces wet-back. The thickness of the multi-ply body-contacting topsheet is less than the thickness of conventional, single ply, nonwoven topsheets.

摘要： The present invention relates to a disposable absorbent article, such as a diaper or an incontinence guard, which includes an inner liquid-permeable casing sheet (1), which lies the closest to the wearer's body when the article is in use, an outer liquid-impermeable casing sheet (2), and an absorbent body (3) which is enclosed between the two casing sheets. According to the invention, the absorbent pad (3) includes, at least in the region thereof which forms the crotch part when the article is worn, a hose-like body (5) which is made of a shape-stable material and which is highly permeable to liquid. The hose-like body is positioned centrally and extends in the longitudinal direction of the article and borders on the inner casing layer and is surrounded by absorbent material (4, 6) at least on the side thereof remote from the inner casing sheet.

摘要： An absorbable core of a disposable absorption product, having an upper polyurethane foam layer which is liquid-permeable and a wrapping layer which is capable of absorbing liquid; the wrapping layer comprises an outer part and an inner part; the outer part is a first liquid-permeable sleeve body; the inner part is an accommodating cavity; a lower polyurethane foam layer and a particle layer are provided inside the accommodating cavity; the particle layer is distributed on an upper surface of the lower polyurethane foam layer and is formed by resin particles, organic acid particles and anhydrous bicarbonate particles mixed together. A disposable absorption product comprising said absorbable core is also provided. By integrating polyurethane polymer foam with superabsorbent polymer particles, organic acid particles and anhydrous bicarbonate particles, the absorbable core is good at absorbing and locking liquid, and provides soft and elastic supporting materials which provide great comfort to users.
