Embodiment 1

[0028] Reference figure 2 , An absorbent paper comprising a first dust-free paper layer 1, a non-woven fabric layer 2 located in the middle layer, and a second dust-free paper layer 3 located in the lower layer. The first dust-free paper layer The paper layer 1 and the second dust-free paper layer 3 are hot-melt bonded along the two sides of the non-woven fabric layer 2 to form an edge 4.

[0029] The hot melt bonding is carried out using the following equipment: Figure 4 , An absorbent paper cutting equipment, comprising a frame 5, on which a paper feed roller 6, a tension roller 7, an ultrasonic cutting machine and a winding device are sequentially arranged. Reference Figure 5 with 6 The ultrasonic cutting machine includes an ultrasonic generator 8, a cutting platform 9, a number of air cylinders 10 and cutting blades 11, and a drive motor. The ultrasonic generator 8 is arranged under the cutting platform 9, and the air cylinder 10 and the cutting blade 11 They are all loca...

Embodiment 2

[0038] Reference image 3 , An absorbent paper comprising a first dust-free paper layer 1, a non-woven fabric layer 2 located in the middle layer, and a second dust-free paper layer 3 located in the lower layer. The first dust-free paper layer The paper layer 1 and the second dust-free paper layer 3 are connected along both sides of the non-woven fabric layer to form a hem 4. The first dust-free paper layer 1, the second dust-free paper layer 3, and the wrapping edge 4 form an integrated structure covering the dust-free layer.

Abstract

The invention relates to water absorption paper. The water absorption paper comprises a first dustless paper layer positioned in an upper layer, a non-woven cloth layer positioned in a middle layer and a second dustless paper layer positioned in a lower layer, wherein the dustless paper is prepared by mixing 60-80% of wood pulp fiber with 20-40% of ES (Ethylene-Propylene Side By Side) fiber by weight according to a dry method of paper-making; and the first dustless paper layer and the second dustless paper layer are hotly molten and bonded along the two sides of the non-woven cloth layer so as to form covered edges. According to the water absorption paper, the first dustless paper layer and the second dustless paper layer are connected along the two sides of the non-woven cloth layer so as to form covered edges, so that the non-woven cloth is closed. Therefore, high molecular particles on the non-woven cloth cannot be leaked out, so that the use effect is improved, the 'diaper rash' due to the high molecular components is avoided, and the resource waste is reduced.

Description

Technical field [0001] The invention relates to an absorbent paper. Background technique [0002] Women's pads, sanitary napkins, disposable diapers, incontinence pads and other daily necessities usually use a kind of absorbent paper containing polymer materials. The traditional absorbent paper structure is like figure 1 As shown, it is a three-layer structure, the upper and lower layers are made of dust-free paper, and the middle layer is made of more than one layer of non-woven fabric, and the non-woven fabric is sprinkled with polymer absorbent particles. Since the upper and lower layers of dust-free paper are not enclosed, the polymer particles on the non-woven fabric will spill out during use, affecting the use effect and causing a large waste of resources. [0003] More seriously, when the absorbent paper is used as a diaper for children, the spilled polymer components will migrate to the surface of the finished product, irritating the skin and causing redness in the botto...
