An anti-stain absorption pad for underpants and an underpants including the same are provided. The absorption pad includes a waterproof layer, at least one absorption layer and two fixing structures; wherein the waterproof layer includes a main body and two inverse-folded parts respectively provided at two opposite sides of the main body; the at least one absorption layer is disposed on the main body, and the at least one absorption layer is used for absorbing a liquid; and the two fixing structures are respectively disposed at the two inverse-folded parts, and fix the two inverse-folded parts on the at least one absorption layer. Therefore, in the present invention, since the fixing structures are covered by the waterproof layer due to the structure of the inverse-folded parts, backflow and secondary leakage of menstrual blood can be avoided, thereby achieving a complete leakproof effect.

Absorbent laminates and multi-layer, folded absorbent cores comprising the absorbent laminates for use in absorbent articles are presented. Specifically, multi-layer, folded absorbent cores are presented that are formed from an absorbent laminate comprising an absorbent layer between two tissue layers, in which the absorbent core includes a central channel running longitudinally along the core and crenellations profiled along the thickness of the core and providing enhanced liquid distribution across the core surface area or profile and improved liquid absorption into the laminate.

An absorbent core for absorbent articles such as diapers. The core comprises a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The average basis weight of the absorbent material in the central absorbent zone is lower than the average basis weight of the absorbent material in the lateral absorbent zones.

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The absorbent core comprises at least one transversal folding line, preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.

Absorbent laminates and multi-layer, folded absorbent cores comprising the absorbent laminates for use in absorbent articles are presented. Specifically, multi-layer, folded absorbent cores are presented that are formed from an absorbent laminate comprising an absorbent layer between two tissue layers, in which the absorbent core includes a central channel running longitudinally along the core and crenellations profiled along the thickness of the core and providing enhanced liquid distribution across the core surface area or profile and improved liquid absorption into the laminate.

Absorbent laminates and folded multi-layer absorbent cores including one or more of the present absorbent laminates The present absorbent laminates comprise an absorbent layer between two laminate layers, at least one of which absorbent laminates including a spunlace nonwoven. Some of the present multi-layer absorbent cores are folded to define a channel running longitudinally along the core to enhance liquid distribution and absorption.

In a particular implementation, an absorbent article includes a chassis having opposing front and rear waist portions and a crotch portion extending longitudinally between the front and rear waist portions. The crotch portion is configured to conform about at least one of a wearer's groin area, perineum, and rear when the chassis is configured in a wearable configuration. The absorbent article also includes an absorbent core extending longitudinally along the crotch portion and including a laminate The laminate is longitudinally folded such that the absorbent core includes a lower layer spanning a portion of a lateral width of the absorbent core. The lower layer includes a first portion and a second portion. The absorbent core also includes a plurality of folded layers of the laminate disposed over the lower layer and configured to define one or more non-overlapping channels.

Disposable absorbent articles suitable for providing leakage protection for users that experience relatively small to relatively large discharges of fluids are described. The article includes a primary topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. The absorbent system includes a first absorbent core and a second absorbent core, and wherein the primary topsheet and at least the first absorbent core include a plurality of recessed areas.

Provided is an absorbent pad which prevents leakage of excess liquid excrement to the exterior. An absorbent pad sheet forms an absorbent pad from a liquid-permeable front sheet and a liquid permeable rear sheet, and absorbent polymer particles which absorb liquid excrement and which are provided between the front sheet and the rear sheet. The width in the width direction formed between both side parts folded to the inside is formed as 10-50% of the width of the absorbent pad in the width direction, and some of the absorbent polymer particles at the place at which folding to the inside occurs are made to penetrate the front sheet at the place at which folding to the inside occurs.

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The absorbent core comprises at least one transversal folding line, preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.
