Diapers are essential baby consumables for parents and mothers today. They are more breathable and hygroscopic than diapers, and are not prone to diaper rash and do not have to worry about breeding bacteria. The most important thing in a diaper is the core, which directly determines the quality of the diaper's water absorption and breathability. Here are the pros and cons of each of the four types of absorbent paper.

1. Wood pulp core-absorbent paper

The wood pulp core is formed by mixing wood pulp and polymer water-absorbent resin without delamination.


This type of diaper uses wood pulp fibers to guide urine into the core, and then locks the urine through the strong water locking performance of the polymer material (also called  absorbent paper ) itself, so that the surface of the diaper can absorb a certain amount of water. Stay dry after the amount of urine.


Due to the existence of wooden oars, there is always no way to solve some of the faults. However, due to the excellent combing performance of wood pulp fiber for urine, it is widely used in some international big brand diaper products.

2. Dual core-absorbent paper

This kind of structure is similar to sheet lamination ( absorbent paper and wood pulp layer are like lamination of sheets of flat paper, plus non woven fabric). The laminated structure makes the diaper not as loose in structure as the composite structure of polymer and wood pulp, and optimizes the structural design while increasing the water absorption.


The wood pulp layer combs and guides the urine into the core body through the wood pulp fibers, and then absorbs it through the polymer water-absorbing primer layer. The double-layer water absorption capacity is strong and the water absorption capacity is large.


Because of the laminated structure and non-woven fabric, this diaper will be soft.

3. Glue core-absorbent paper

The glue core is formed by mixing hot melt adhesive, non woven fabric and polymer  absorbent paper, and has layers.


It contains a large amount of macromolecules to ensure the absorption capacity of the diaper. After absorbing water, it expands as a whole. Due to the existence of adhesive bonding, it will not be flat and lumpy, and it can maintain its original shape after absorbing liquid.


Because the diaper swells as a whole after absorbing water, it has poor air permeability after absorbing water, and excessive heat and humidity will make the baby's buttocks uncomfortable. Factories with insufficient technical capabilities will leave behind the smell of glue or the diapers will harden after absorbing water, resulting in higher production costs.

4. Braided core-absorbent paper

This type of diaper is woven with breathable, flexible and moisture-proof materials, supplemented by high quality wood pulp to form a specific structure, and then filled with absorbent paper, and a special surface layer is used on the outside.


The non laminated woven core is very thin, and the filled polymer water absorbing primer has a remarkable effect on water absorption and moisture resistance. The specific weaving structure will not cause lumps of faults after water absorption and swelling, and the diversion effect is good.


Compared with the second generation and third-generation diapers, the prominent advantage of this diaper is the higher cost.

Water absorption: ★★★★

Breathability: ★★★★★

Softness: ★★★★☆

Qituo fault: ★★★★


The core is called the "heart" of the diaper. Understanding the pros and cons of the above four types of absorbent paper, and choosing the right diaper according to your own needs is the best choice for parents and mothers.
