Embodiment 1

[0055] Such as figure 2 , in this embodiment, the first filler and the second filler are the same, and both are polymer materials 203 .

[0056] The manufacturing process of the composite core of the present embodiment comprises the following steps:

[0057] Step 1: The coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 are transported by traction and bonded to obtain the lower composite layer, which is transported to the first transfer wheel 105; specifically, the coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 is heat-sealed by the first heat-sealing device 102, and the bonding point 300 of the lower composite layer is formed after heat-sealing; the upper non-woven fabric 113 and the upper hot-air non-woven fabric 112 are transported by traction and bonded to obtain the upper composite layer, which is transported to the second transfer wheel 108; Specifically, the upper non-woven fabric 113 and the upper hot-air ...

Embodiment 2

[0062] Such as Figure 6 , the first filler and the second filler are a mixture of polymer material 203 and fluff pulp 310,

[0063] The manufacturing process of the composite core body of the present embodiment, such as Figure 5 , including the following steps:

[0064] Step 1: The coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 are transported by traction and bonded to obtain the lower composite layer, which is transported to the first transfer wheel 105; specifically, the coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 is heat-sealed by the first heat-sealing device 102, and the bonding point 300 of the lower composite layer is formed after heat-sealing; the upper non-woven fabric 113 and the upper hot-air non-woven fabric 112 are transported by traction and bonded to obtain the upper composite layer, which is transported to the second transfer wheel 108; Specifically, the upper non-woven fabric 113 and the ...

Embodiment 3

[0069] Such as Figure 8 , the first filler and the second filler both include a polymer material layer and a fluff pulp layer, and the polymer material layer is located on the upper layer of the fluff pulp layer.

[0070] The manufacturing process of the composite core body of the present embodiment, such as Figure 7 , including the following steps:

[0071] Step 1: The coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 are transported by traction and bonded to obtain the lower composite layer, which is transported to the first transfer wheel 105; specifically, the coated non-woven fabric 100 and the lower layer of hot-air non-woven fabric 101 is heat-sealed by the first heat-sealing device 102, and the bonding point 300 of the lower composite layer is formed after heat-sealing; the upper non-woven fabric 113 and the upper hot-air non-woven fabric 112 are transported by traction and bonded to obtain the upper composite layer, which is transporte...

Abstract

The invention relates to the technical field of disposable sanitary articles, in particular to a composite core and a manufacturing device and technology thereof. The composite core includes an uppercomposite layer and a lower composite layer, the upper composite layer at least comprises an upper surface layer and an upper lining layer which are mutually compounded, the lower composite layer at least comprises a lower surface layer and a lower lining layer which are mutually compounded, the space between the upper composite layer and the lower composite layer is filled with filler, the fillerincludes first filler paved in the upper lining layer and second filler paved in the lower lining layer, the composite core includes a number of diversion trenches, the lower lining layer, the lowersurface layer, the upper lining layer and the upper surface layer are compounded at the diversion trenches, there is no filler in the diversion trenches, the composite core has good diversion and diffusion performance, high in seepage velocity and small in reverse osmosis amount, super absorbent resin can permeate the three-dimensional space of a hot-air nonwoven fabric, the quality of composite core products is improved, and the comfort levels of the composite core products are improved when people use the composite core products.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to a composite core body and a manufacturing device and process thereof. Background technique [0002] Absorbent cores are used in many disposable hygiene products, such as diapers, maternity pads, medical surgical pads, sanitary napkins, pet pads, and even disposable table pads. [0003] Absorbent core is the most important component of disposable absorbent products. The performance of disposable absorbent products is mainly determined by absorbent core, such as water absorption, retention, diffusibility, etc. Consumers of current absorbent articles are demanding thinner absorbent articles. To meet these requirements, manufacturers are reducing the thickness of absorbent articles by making composite cores. In the prior art, most composite cores are made of an upper layer material, a middle layer of bulky non-woven fabric, and a lower layer material. The uppe...
