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.

A unitary storage layer for an absorbent article, being formed by at least two sub-layers in which a first outermost sub-layer forms said first surface and includes cellulose pulp fibers and cross linked cellulose fibers and includes less than 5% of SAP by weight of the sub-layer, and a second sub layer which includes cellulose pulp fibers and SAP and is immediately adjacent to said first sub-layer.

The diaper of the present invention is a fixed flat cloth diaper. The diaper is ‘fixed’, because an outer layer of the diaper resembles the final format of a flat, rectangular cloth diaper having been folded origami style into a shape suitable for donning on a wearer by a user. The outer layer functions primarily to retain the diaper upon the wearer and has a stomach panel for obtaining a good closure of the diaper on the wearer. The diaper is ‘flat’, because an inner layer of the diaper is attached to the outer layer, and the inner layer is a flat, rectangular shape which is customizable for absorbency and can be folded into a flat insert configuration of the user's choice prior to donning the diaper on the wearer. The inner layer functions primarily to absorb waste (urine and feces) excreted by the wearer.

The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing and positioning particulate materials in a desired pattern onto a moving carrier layer. The method allows accurate forming of a pattern of particulate material clusters at high production speed having improved attachment properties, with reduced raw material usage and relative low cost. The present invention foresees in the need for improved thin, flexible, lightweight absorbent structure having optimal absorption, distribution and retention.

An absorbent core comprising a front portion; a back portion; a middle portion positioned between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core being a multi-layer core comprising at least two distinct core layers, wherein a first core layer comprises a first concentration of super absorbent polymer therein and a second core layer comprises a second concentration of super absorbent polymer therein said first and second concentrations being different, wherein at least said first core layer comprises one or more channels, said channel(s) being continuous and interconnected at least along the length and the width of said core such that at least two channel portions extending along said length are in fluid communication via a connecting channel portion positioned proximal to said back portion.

An embodiment of the undergarment can include an undergarment liner comprising a top layer; a bottom layer; an absorption layer; and a garment adhesive layer. The top layer can be oriented as the upper most layer and is the layer that comes in contact with the wearer of the liner. The absorption layer is oriented between the top layer and the bottom layer. The garment adhesive layer can comprise a coupling surface and an adhesion surface. The coupling surface opposes adhesion surface. The undergarment liner also comprises a first perforation line that extends through each layer and subdivides the undergarment liner into a plurality of subsections.
