Embodiment 1

[0026] as attached figure 1 , figure 2 As shown, the disposable absorbent product with anti-bottom penetration and high air permeability of this embodiment includes a liquid-permeable top layer 106, a liquid-impermeable side leakage prevention layer 103, a liquid-impermeable bottom layer 101, and a liquid-permeable top layer and The absorbent core 102 between the liquid impervious backsheets. The absorbent core 102 is formed by connecting the superabsorbent resin layer 4 , the fluffy cotton layer 5 and the superabsorbent resin layer 4 from top to bottom.

[0027] as attached figure 2 , image 3 and Figure 4 As shown, the structural characteristics of the anti-bottom permeation and highly breathable disposable absorbent product of this embodiment are: first, a fluff pulp layer 104 is arranged on the absorbent core 102, and its thickness is 0.2-5 mm, and is passed through a spiral The hot-melt adhesive layer 105 is connected as a whole with the absorbent core 102; second...

Embodiment 2

[0031] In order to overcome the problem of looseness between the fibers in the existing fluff pulp layer, this embodiment selects fluff pulp fibers that can be super-compressed in the existing materials, so that the fluff pulp layer has the strength of longitudinal drafting, and it is compatible with The strength of the bond between the cover or absorbent core. Embossing is provided on one or both sides of the fluff pulp layer, and the shape of the embossing can be diamond-shaped embossing, heart-shaped embossing, or star-shaped embossing, so that the thickness of the fluff pulp layer is 0.5 -1.5mm.

[0032] as attached image 3 As shown, this embodiment removes the permanent upper cover layer or / and lower cover layer in the existing composite absorbent core, and replaces the upper cover layer or / and lower cover layer with an ultra-thin fluff pulp layer 104, and then wraps Layer 2, such as air-through nonwoven fabric, hot-rolled nonwoven fabric, spunbonded nonwoven fabric or...

Embodiment 3

[0034] In this example, on the basis of Example 1 or Example 2, the composite absorbent core in the disposable absorbent product with anti-bottom penetration and high air permeability is further improved. as attached Figure 5 As shown, the composite absorbent core of this embodiment is composed of two layers of fluff pulp layer and two layers of absorbent core, wherein the fluff pulp layer is arranged on the absorbent core, and its structure is: the fluff pulp layer 104, the absorbent core The layer 102, the fluff pulp layer 104, and the absorbent core layer 102 are stacked from top to bottom, connected as a whole by a spiral hot-melt adhesive layer, and wrapped with the wrapping layer 2 in the circumferential direction.

[0035] In this embodiment, the wave-like fluffy cotton layer 5 is used as the skeleton structure of the absorbent core. In a specific embodiment, as attached Figure 5 As shown, each absorbent core 102 is formed by connecting superabsorbent resin 4 , wavy...

Abstract

The invention relates to a rapid-guide-absorption and anti-return-permeation disposable absorption product. The rapid-guide-absorption and anti-return-permeation disposable absorption product comprises a liquid-permeability top layer, a non-liquid-permeability anti-side-leakage layer, a non-liquid-permeability bottom layer and an absorption core arranged between the liquid-permeability top layer and the non-liquid-permeability bottom layer; the absorption core is formed by connecting a super absorbent resin layer, a fluffy cotton layer and a super absorbent resin layer from top to bottom respectively, and a fluff pulp layer with the thickness of 0.2 mm to 5 mm is arranged above the absorption core, and is integrated with the absorption core through a spiral hot melt glue layer; the fluffycotton layer is the wavy fluffy cotton layer. The rapid-guide-absorption and anti-return-permeation disposable absorption product has the advantages that rapid absorption is achieved, temporary liquidstorage is achieved, rapid infiltration can also be conducted, common urine leakage and red buttock phenomena of an existing disposable absorption product can be effectively avoided, the return-permeation amount of the disposable absorption product in the using process is also avoided, the dry and comfortable performance is improved, and using experiences of the disposable absorption product areimproved.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to a disposable absorbent product with rapid diversion absorption and anti-rewet. Background technique [0002] Infants and other people who cannot take care of themselves often need to wear disposable absorbent products, such as diapers, diapers, sanitary napkins, pull-up pants, etc., the purpose of which is to store excrement and make these excrement and the wearer's body , clothing, bedding, etc., while the absorption medium of disposable absorbent products is the absorbent core, and the traditional absorbent core is made of fluff pulp fibers and superabsorbent resin particles. However, although the traditional absorbent core has the advantage of fast absorption, it also has the serious problem of liquid rewet at the same time, so it is gradually replaced by the composite absorbent core with excellent rewet performance. [0003] At present, the composite com...
