Embodiment 1

[0037] as attached figure 1 , figure 2 and image 3 As shown, the composite absorbent core 1 of this embodiment consists of a first covering layer 8 located at the top of the composite absorbent core 1, a second covering layer 10 located at the bottom of the composite absorbent core 1, and connected to the first covering layer 8. An absorbent core layer 9 is formed between a cover layer and a second cover layer, wherein the first cover layer 8 can be selected to have a square grammage of 10-30 g / m 2 The dust-free paper layer, the second covering layer 10 is 10-30g / m2 with a square gram weight 2 Dust-free paper layer or air-through non-woven layer.

[0038] In the central area of ​​the top of the composite absorbent core 1, there are two wavy embossments 4 and 5 extending to both ends in the longitudinal direction of the composite absorbent core as strip embossments. The wavy embossments 4, The wave-shaped embossing 5 is sunken from the first covering layer along the thick...

Embodiment 2

[0045] as attached Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, wavy embossings are respectively provided as strip embossings in the central areas of the top and bottom of the composite absorbent core 1, including:

[0046] 1) In the central area of ​​the top of the composite absorbent core 1, there are respectively arranged two ridges extending along the longitudinal direction of the composite absorbent core to both ends, and the peaks and troughs are respectively arranged opposite to each other, and are distributed axially symmetrically along the longitudinal centerline of the composite absorbent core. Wave embossing 4, wave embossing 5, wave embossing 4, wave embossing 5 respectively from the first cover layer, the second cover layer from the inside along the thickness direction of the composite absorbent core.

[0047] 2) In the central area of ​​the bottom of the composite absorbent core 1, there are respectively ...

Embodiment 3

[0050] as attached figure 1 , figure 2 , image 3 As shown, this embodiment is based on the strip embossing technical solution of embodiment 1. In this embodiment, the proximal edge 2 and the proximal edge 3 in the transverse width direction of the composite absorbent core 1 are respectively provided with The longitudinal direction of the composite absorbent core extends to both ends of the side seals 22, side seals 32, the side seals 22, side seals 32 respectively connect the absorbent core layer 9 with the adjacent first covering layer 8 or / and the second covering layer 10 are connected in a side seal. in:

[0051] 1) The side seals 22 are formed by a plurality of short embossings 21 arranged at intervals along the longitudinal direction of the composite core at the proximal edge 2 of the composite core 1, and one end 211 of the short embossing 21 is connected to the composite core. The longitudinal side edge 101 communicates to form an opening, while the other end 21...

Abstract

The invention relates to a compound absorption core. The compound absorption core comprises a first coverage layer, a second coverage layer and an absorption core body layer which is connected betweenthe first coverage layer and the second coverage layer, and the compound absorption core is structurally characterized in that a plurality of enhanced absorption flow guide bodies which extend to thetwo ends in the longitudinal direction of the compound absorption core are arranged on the compound absorption core, so that the strength and the diffusion absorption performance of a core body of the compound absorption core are improved. Each enhanced absorption flow guide body is linearly embossed, so that the absorption core body layer is in enhanced connection with the adjacent first coverage layer or / and the second coverage layer. Side seal bodies which extend to the two ends in the longitudinal direction of the compound absorption core are arranged at the position, close to the two near-side edges, in the transverse width direction of the compound absorption core, the side seal bodies make the absorption core body layer in side seal connection with the adjacent first coverage layeror / and the second coverage layer respectively. The compound absorption core has excellent strength, flow guide diffusivity and absorption performance.

Description

technical field [0001] The invention relates to the field of disposable absorbent products, in particular a composite absorbent core. Background technique [0002] Generally speaking, baby absorbent products include baby diapers, disposable diapers, pull-out cups, etc., all of which are composed of multiple layers of materials, including inner surface materials, absorbent materials, etc. Along with the raising of people's living standard, because baby diaper has the advantage of being easy to carry, clean and hygienic, therefore, the application of baby diaper is more and more extensive. Baby absorbent products pay more and more attention to comfort and practicality, and the application of baby absorbent products facilitates people to raise babies. [0003] Due to the use of traditional technology, the diapers are relatively thick and heavy, which brings inconvenience to infants and young children's activities, and it is easy to lump and break after long-term use, so it is ...
