Technical Field

[0001] The utility model relates to the technical field of sanitary products, and more specifically, to an improved SAP breathable and water-absorbent paper core. Background Art

[0002] Diapers are commonly used daily necessities for babies, and are another name for disposable diapers, paper diapers or pull-up pants. A dry diaper can keep a baby sleeping soundly throughout the night. Because of its strong water absorption, it is commonly known as "disposable diaper". The absorbent paper core of a diaper contains super absorbent polymer (abbreviation: polymer SAP), and its water absorption and water storage capacity are astonishing.

[0003] The existing water-absorbent paper core has poor air permeability, is prone to breeding bacteria, causing itching of the buttocks, and urgently needs improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide an improved SAP breathable and water-absorbent paper core in order to solve the above technical problems.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

The upper surface of the hot air non-woven fabric layer is provided with protrusions and water seepage holes, and the protrusions and water seepage holes are arranged in a uniform and staggered manner.

[0007] Structural principle: The gaps formed between the protrusions increase the air flow to improve air permeability, keep it dry and avoid skin itching. The arrangement of the water seepage holes facilitates the rapid diversion of liquid to be absorbed, improving the absorption efficiency of the water-absorbent paper core.

[0008] A fragrance layer is arranged between the water-absorbing layer and the coated dust-free paper.

[0009] The fragrance layer includes a reticulated expanded non-woven fabric and tea powder, and the tea powder is arranged in the reticulated gaps of the reticulated expanded non-woven fabric. The tea powder can bring a fresh smell, and also has anti-inflammatory and antibacterial effects, avoiding the generation of peculiar smell.

[0010] The water-absorbing layer includes hydrophilic ES fibers and super absorbent polymer uniformly distributed on the hydrophilic ES fibers. The hydrophilic ES fibers have good hydrophilicity, high strength and good elasticity. The arrangement of the water-absorbing layer has good water absorption.

[0011] The water-locking layer includes cellulose fibers and superabsorbent resin uniformly distributed on the cellulose fibers. The cellulose fibers have good water-locking property, and the setting of the water-locking layer improves the water absorption performance of the absorbent paper core.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, gaps are formed between the protrusions to increase the air flow, improve the air permeability, keep it dry, and avoid skin itching. The arrangement of the water seepage holes facilitates the rapid diversion and absorption of liquid, improving the absorption efficiency of the absorbent paper core; the tea powder can bring a fragrant smell and also has anti-inflammatory and antibacterial effects, avoiding the generation of peculiar smell.
