Paper diaper core and preparation method thereof

Abstract

The invention relates to a paper diaper core. The paper diaper core comprises an absorption core of a multi-layer structure, wherein an H-shaped flow guide groove (12) is formed in the absorption core (10), the absorption core (10) is of a five-layer structure and sequentially comprises a first wrapping layer, a first macromolecule layer, a fluffy cotton layer, a second macromolecule layer and a second wrapping layer, and the H-shaped flow guide groove (12) penetrates through the five-layer structure of the absorption core (10). The weight ratio of macromolecule water-absorbent resin particles of the first macromolecule layer to the macromolecule water-absorbent resin particles of the second macromolecule layer is 2:3. The paper diaper core is high in polymer utilization rate and low in cost, is provided with the special flow guide groove, can improve the flow guide efficiency and increase the polymer utilization rate, and overcomes the defects in the prior art.

Description

technical field [0001] The invention relates to a diaper core body and a preparation method thereof, which belong to the field of hygiene products for infants and young children. Background technique [0002] Diapers are disposable sanitary products composed of non-woven fabrics and absorbent cores, which are mainly used to absorb excreta such as urine. The part of diapers that absorbs urine is the absorbent core, and the absorbent core is one of the important components in the manufacture of disposable sanitary products such as diapers, sanitary napkins, and panty liners. Diaper cores in different regions of the world have different designs, mainly divided into fluff pulp cores and composite cores. [0003] In the prior art, diapers include a trouser body and an absorbent part. The absorbent part includes an upper surface layer, a lower surface layer, and an absorbent core disposed between the upper and lower surface layers. Usually, the absorbent core is cut into a certai...

AI Technical Summary

Problems solved by technology

Once the SAP in the diaper is blocked by gel, it will cause insufficient diffusion of the liquid in the diaper, which will affect the speed of urine infiltration. The chance of leakage is relatively high when used at night, and it may cause skin rash.

Because of polymer gel clogging, diapers with composite cores on the market usually have a low utilization rate of SAP, and urine cannot diffuse to both ends, resulting in waste

[0006] To sum up, the existing paper diapers have the following problems: (1) The gel of the superabsorbent resin is easy to cause clogging, which makes the liquid diffusion ability poor, thereby causing local moisture and causing the user's skin rash

(2) The utilization rate of SAP in both ends of the composite core is low, the use effect is poor, and there is a lot of material waste
