Embodiment 1

[0022] refer to figure 2 , a kind of water-absorbing paper, said water-absorbing paper comprises the first dust-free paper layer 1 on the upper layer, the non-woven fabric layer 2 on the middle layer and the second dust-free paper layer 3 on the lower layer, said first dust-free paper layer The paper layer 1 and the second dust-free paper layer 3 are hot-melt bonded along both sides of the non-woven fabric layer 2 to form an edge wrapping 4 .

[0023] Described hot-melt bonding adopts following equipment to carry out: with reference to Figure 4 , a water-absorbing paper cutting equipment, including a frame 5, the frame is sequentially provided with a paper feed roller 6, a tension roller 7, an ultrasonic cutting machine and a winding device. refer to Figure 5 and 6 , the ultrasonic cutter includes an ultrasonic generator 8, a cutting platform 9, several cylinders 10 and cutters 11, and a drive motor, and the ultrasonic generator 8 is arranged below the cutting platform 9...

Embodiment 2

[0032] refer to image 3 , a kind of water-absorbing paper, said water-absorbing paper comprises the first dust-free paper layer 1 on the upper layer, the non-woven fabric layer 2 on the middle layer and the second dust-free paper layer 3 on the lower layer, said 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 an edge 4 . The first dust-free paper layer 1 , the second dust-free paper layer 3 and the edge wrapping 4 form an integral structure covering the paper-free dust 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] Feminine 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 as follows: figure 1 As shown, it is a three-layer structure. The upper and lower layers use dust-free paper, and the middle layer uses more than one layer of non-woven fabric, and the non-woven fabric is sprinkled with polymer water-absorbing particles. Since the upper and lower layers of dust-free paper are not closed, 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] What's more serious is that when this kind of absorbent paper is used as a child's diaper, the spilled polymer components will migrate to the surface of the finished product, irritating the skin and causing r...
