Embodiment 1

[0042] Such as Figure 1-2 As shown, a preparation method of a composite absorbent core, the composite absorbent core includes an upper layer material, a middle layer material and a lower layer material stacked in sequence, the upper layer material includes a first carrier layer 13, a second carrier layer 14, and the A diversion structure between the carrier layer 13 and the second carrier layer 14, the diversion structure includes several first strip-shaped wood pulp layers 11 arranged in sequence along the horizontal direction, and the width of the first strip-shaped wood pulp layer 11 is 10 mm, corresponding to The spacing of the adjacent two first strip-shaped wood pulp layers 11 is 10mm, and the first resin layer 12 is covered on several first strip-shaped wood pulp layers 11, and the spreading width of the first resin layer 12 is 8mm; Including the absorbent base layer 21, the absorbent base layer 21 is a fluffy non-woven fabric, composed of 70% three-dimensional hollow ...

Embodiment 2

[0051] The difference between Embodiment 2 and Embodiment 1 lies in: the specific selection of each material layer, see Table 2 below for details.

[0052] Table 2 The material list of the composite absorbent core of Example 2

[0053]

[0054]

[0055] All the other are identical with specific embodiment 1.

Embodiment 3

[0057] The difference between embodiment 3 and embodiment 1 is that: in the upper material, the width of the first strip-shaped wood pulp layer is 15mm, and the distance between two adjacent first strip-shaped wood pulp layers is 25mm, and the first resin The spreading width of the layer is 18mm; in the material of the lower layer, the width of the second strip-shaped wood pulp layer is 30mm, and the distance between two adjacent second strip-shaped wood pulp layers is 20mm.

[0058] All the other are identical with specific embodiment 1.

Abstract

The invention discloses a composite absorption core and a preparation method thereof. The composite absorption core comprises an upper-layer material, a middle-layer material and a lower-layer material which are sequentially stacked, wherein a flow guide structure is arranged in the upper-layer material and comprises a plurality of first strip-shaped wood pulp layers which are sequentially arranged in the horizontal direction, and first resin layers are arranged on the first strip-shaped wood pulp layers; the middle layer material comprises an absorption base layer, and at least one second resin layer is arranged on the absorption base layer; and the lower layer material comprises a plurality of second strip-shaped wood pulp layers which are sequentially arranged in the horizontal direction. The composite absorption core is novel and stable in structure, good in flow guide effect and excellent in liquid conduction capacity, and the use comfort is greatly improved. The composite absorption core provided by the invention can be applied to hygienic products, including infant paper diapers, pull-ups, sanitary towels, menstrual period pants, adult paper diapers, incontinence pants and urine isolation pads.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to a composite absorbent core and its preparation method and application. Background technique [0002] Disposable sanitary products such as sanitary napkins, baby diapers, adult diapers, baby pull-up pants, adult pull-up pants, etc., generally have a multi-layer structure, and the absorption area mainly includes the surface covering layer (surface layer, acquisition layer), absorbent core and backsheet. The quality of the absorbent core has a crucial impact on the quality of the product. The production method of the absorbent core of common products is as follows: After the wood pulp is pulverized by a pulverizer, it is then mixed with polymers in the forming chamber to form, and finally molded into a core through a template. The structure of the product obtained by this core production method is simple, only wood pulp and polymers are mixed, although it can ...
