Problems solved by technology

[0002] The composite core of diapers is the most important part of disposable absorbent products. The performance of disposable absorbent products is mainly determined by the composite core, such as water absorption, retention, diffusibility, etc. The composite core is composed of the upper liquid-permeable sheet Material, the middle bulky non-woven fabric and the lower liquid-absorbent sheet, the existing polymer diaper composite core mainly has two forms: one is a composite core of fluffy non-woven fabric and polymer particles, which is easy to combine The other is to mix crushed wood pulp with polymer particles or powder, which is prone to dust and affects the working environment in the workshop

Embodiment 1

[0049] Please refer to Figure 1 to Figure 3 Shown, embodiment one of the present invention is:

[0050] A composite core body for diapers, the composite core body includes a surface layer 1, a wood pulp paper layer 2 and a waterproof layer 3 arranged sequentially from top to bottom;

[0051] The surface layer 1 includes a soft layer 11 and a hydrophilic non-woven layer 12, the soft layer 11 is arranged on the upper surface of the hydrophilic non-woven layer 12, and the soft layer 11 is provided with aromatic substances, The upper surface and the lower surface of the hydrophilic non-woven fabric layer 12 are provided with a plurality of strip-shaped and spaced glue-coating points 4, and the soft layer 11 passes through the glue-coating spots 4 and the hydrophilic non-woven fabric layer 12. The upper surface of the wood pulp paper layer 2 is connected to the lower surface of the hydrophilic non-woven fabric layer 12 through the glue point 4;

[0052] The wood pulp paper layer...

Embodiment 2

[0059] Please refer to Figure 1 to Figure 3 Shown, another embodiment two of the present invention is:

[0060] The present invention also provides a processing method for the composite core of diapers, which is applied to the composite core of diapers described in Example 1. The processing method includes the following steps:

[0061] Step 1, coating the lower surface of the surface layer 1 with a plurality of strip-shaped glue dots 4 arranged at intervals;

[0062] Step 2, process a plurality of parallel ditches 22 on the upper half of the wood pulp paper layer 2, transport the polymer water-absorbing particles 21 to the ditches 22 of the wood pulp paper layer 2 through the feeding syringe, and absorb the polymer water The particles 21 are arranged at intervals in the ditch 22;

[0063] Step 3, laying the surface layer 1 described in step 1 on the wood pulp paper layer 2 sprinkled with polymer water-absorbing particles 21 described in step 2, and the surface layer 1 and t...

Abstract

The invention relates to the technical field of paper diaper processing, and particularly relates to a paper diaper composite core and a processing method thereof. The composite core comprises a facelayer, a wood pulp paper layer and a waterproof layer which are orderly arranged from top to bottom; the face layer comprises a soft cotton layer and a hydrophilic non-woven cloth layer; the soft cotton layer is arranged at the upper surface of the hydrophilic non-woven cloth layer, and an aromatic substance is arranged on the soft cotton layer; the upper surface and the lower surface of the hydrophilic non-woven cloth layer are provided with multiple strip-shaped glue coating points arranged at intervals; the soft cotton layer is connected to the upper surface of the hydrophilic non-woven cloth layer through the glue coating point. The paper diaper composite core has the beneficial effects of being simple in structure design; through processing a channel on the upper half part of the upper surface of a wood pulp paper layer, a macromolecular water absorbing grain is prepared to be fiber or cloth face, the macromolecule water absorbing grains are paved in the channel at intervals; thusthe paper diaper composite core prevents the macromolecule water absorbing grains in the composite core from dropping out and generating powder dust easily; the composite core body is not easy to clot.
