The invention provides a sanitary absorption article, which comprises a liquid-permeable surface layer 101, a diversion layer 102, an absorption layer 103 and a breathable bottom layer 104 which are sequentially arranged from top to bottom as shown in figure 1;
the liquid-permeable surface layer 101 is a fine denier non-woven fabric added with shea butter essence; the single-filament fineness of the fine-denier non-woven fabric is 1-3 deniers;
the flow guide layer 102 is formed by compounding a PE film with a perforated structure and non-woven fabrics;
the absorption layer 103 is a foam layer or super absorbent resin absorbent paper.
It should be noted that the drawings of the present invention are provided for illustrative purposes only, and the scale of the components in the drawings is not necessarily consistent with the actual product.
In fig. 1 and 2 of the present invention, the structural layers are peeled off from each other in order to clearly illustrate the positional relationship between the structural layers of the present invention, and it should be understood that the structural layers of the present invention are in close and/or partial close contact with each other.
According to some preferred embodiments, as shown in fig. 2, both sides of the liquid-permeable surface layer 101 are provided with a tridimensional containment 105 that is higher than the liquid-permeable surface layer and comprises an inner containment (a) and an outer containment (B).
In the present invention, the outer leg cuff of the liquid-permeable top sheet 101 includes a liquid-permeable top sheet and a breathable back sheet, and at least two elastic bands are combined with the inner leg cuff.
In the invention, the two sides of the liquid-permeable surface layer are provided with the three-dimensional fencing, so that the liquid can be effectively prevented from leaking laterally.
According to some preferred embodiments, the liquid-permeable top sheet 101 is at least one selected from the group consisting of a through-air nonwoven fabric, a spunbond nonwoven fabric, a pure cotton nonwoven fabric, and bamboo fibers.

According to some more preferred embodiments, the liquid-permeable top sheet 101 is a through-air nonwoven.
According to some preferred embodiments, the content of the shea butter essence in the liquid-permeable top layer 101 is 0.05 to 5% (e.g., may be 0.05%, 0.1%, 0.3%, 0.5%, 0.6%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, or 5%) based on the total weight of the liquid-permeable top layer.
It should be noted that the shea butter essence (namely, the content of the shea butter is 100%) is added to the liquid-permeable surface layer, and the shea butter is mainly because the shea butter is closest to each index of sebum secretion oil of a human body, contains rich non-saponification components, contains phytol and VE, has super-strong antioxidant effect and excellent repairing anti-inflammatory effect, can prevent skin from drying and cracking, is mild and non-irritant, and further has the effects of skin care, inflammation diminishing and bacteriostasis.
