Problems solved by technology

[0002] Hygienic products such as breast pad diapers or sanitary napkins used by breast-feeding women in the prior art include a hydrophilic layer, an absorbing layer and a water-repellent layer (also called a waterproof layer) that are sequentially laminated; the hydrophilic layer and the repellent layer The surrounding of the water layer is bonded to accommodate the absorbent layer between the hydrophilic layer and the water-repellent layer; the absorbent layer mainly includes polymer water-absorbent resin (SAP for short) wrapped by non-woven fabric, and its disadvantages are: the hydrophilic layer The space between the waterproof layer and the waterproof layer is small, so that the SAP in the absorbent layer has insufficient space to expand after absorbing water, resulting in the SAP being unable to fully absorb water, making it far from reaching the saturated state of water absorption, and then manufacturers can only add more SAP to make larger products Size to meet the requirements of water absorption, resulting in the waste of related raw materials and SAP, and also put a certain pressure on environmental protection

Embodiment 1

[0028] Such as Figure 3-4 As shown, the hygienic article with better water absorption performance in this embodiment is a breast pad, which includes a hydrophilic layer 1, an absorbent layer 2, and a waterproof layer 3 that are sequentially stacked. The hydrophilic layer 1 and the waterproof layer 3 are symmetrical up and down, and the surrounding The edges are connected by hot pressing roller fusion or ultrasonic welding to form a fusion ring 4 .

[0029] A pair of folded layers 5 are arranged on both sides of the waterproof layer 3 , and the two ends of the folded layers are connected to the hydrophilic layer 1 and the surrounding edges of the waterproof layer 3 through hot pressing roller fusion or ultrasonic welding. The folded layer is formed by turning outward once (such as Figure 12 ), can also be folded inward once (such as Figure 4 ).

[0030] Preferably, one or more points on the folded layer of the waterproof layer 3 are bonded or ultrasonically welded on the ...

Embodiment 2

[0033] On the basis of Embodiment 1, the breast pad in this embodiment has the following modifications:

[0034] Such as Figure 6-8 , the center of the hydrophilic layer 1 and / or waterproof layer 3 is provided with a folded layer 5 .

[0035] Another implementation is, as in Figure 9 , the center of the waterproof layer 3 is provided with a folded layer 5 , and the two sides of the hydrophilic layer 1 are provided with a pair of folded layers 5 . Fold layer 5 inside out.

[0036] Another implementation is, as in Figure 10 , a pair of folded layers 5 on both sides of the hydrophilic layer 1 are everted.

Embodiment 3

[0038] On the basis of Embodiment 1 or 2, the difference of this embodiment is: the sanitary product of this embodiment is a diaper or a sanitary napkin.

Abstract

The invention relates to a high-water-absorbency hygienic product with folding layers, specifically to a breast pad, or a baby diaper, or a sanitary towel. The high-water-absorbency hygienic product with the folding layers comprises a hydrophilic layer, an absorbing layer and a waterproof layer which are sequentially laminated, both sides of the hydrophilic layer and / or the waterproof layer are provided with a pair of the folding layers, or the middle of the hydrophilic layer and / or the waterproof layer is provided with one folding layer; the absorbing layer can outwards expand the folding layers after absorbing a certain amount of water so as to provide super absorbent polymer (SAP) inside the absorbing layer with sufficient expansion space, then the SAP can fully absorb water to reach asaturated state, and further the SAP can be made full use of or can be applied less when absorbing an identical amount of water. Tests show that, compared with the prior art, the h high-water-absorbency hygienic product with a folding layer can improve the water absorbency by 15% under the condition of 10% less application of the SAP.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a sanitary product including breast pads, diapers, sanitary napkins and the like.
