The complete production process of one piece of diaper


Material selection determines the softness and dryness of diapers

Although the diaper is thin, in fact, it has 5 layers of structure. The selection of each layer of structure is crucial, it determines directly whether the diaper is soft and delicate in contact with the skin, can quickly absorb urine and keep the skin dry or not.


Hot Air Through 3D Pearl Topsheet surface: Reduced friction, fast absorption

As the first layer of close contact with the baby's skin, the touch and absorption effect of the surface layer are supposed to directly determine the baby's wearing experience.

Therefore, the material requirements for the topsheet surface layer are very high-level. Feeling soft and not stimulating skin is the bottom line. in addition, it must also do rapid urine diversion to reduce contact time between irritating excreta and baby butt.

In order to reduce the friction between the skin and the diaper topsheet surface layer effectively, we chose NEWBUSI large-particle embossing structure. If you Look closely, the surface looks like a 3D small pearl arranged, which is very smooth and touch really soft.

In addition, these small raised pearls have another important role in forming a "channel" for urine which is like a guide to direct the urine into each small groove evenly and seeping down quickly to the absorption layer.


The following is the slip infiltration test, which can directly show the absorption speed and absorption capacity of the product to the urine. When the test liquid which is modelled on urine, is poured down, it is absorbed quickly by the topsheet surface layer without a drop falling into the cup at the bottom.


Zoom in on the details, liquid gets absorbed wherever the it flows.



Super Absorbent Polymer core: fast absorption, not easy to reverse osmosis

The absorption core is the most important functional layer in the diaper, which shoulders the burden of eventually absorbing and storing urine. Therefore the requirements for it can be said to be the highest-level, and it must absorb quickly, absorb much, and not easy to reverse osmosis.

We chose the NEWBUSI second generation absorption core.

It has two layers of the main absorption part, which are respective fluffy absorber and absorption cotton core. The double-layer structure can effectively enhance the strength of the core, so that it is not easy to be broken and stratification.

In particular, the fluffy layer on the surface is specially made of polymer structure, which has fast absorption speed and high efficiency. And it can also be stacked in multiple layers to greatly increase the amount of absorption.


China's national standard requires that the first time absorption speed of diapers should be ≤ 50 s, and the second absorption time speed should be ≤ 100 s. After testing our diaper with NEWBUSI material, the first time absorption speed is only 19 s, the second time is only 31 s, much faster than the national standard requirements.





It is not only required to suck fast, the high-quality diaper core body should be non-reosmosis and non-reverse osmosis. The urine should be firmly locked in the absorption core to prevent it from oozing and irritating the baby's skin.

According to the test report, the reosmosis amount of this pull up pants is only 0.1g, and the penetration amount is only 0.3g, which is not easy to reverse osmosis, so that the baby's skin can keep dry and comfortable all the time.


High weight hot air laminated backsheet: delicate and soft, breathable and humid

If you want the overall feel of the diaper to be good, the material of the bottom can not be neglected. It should be not only leak-proof, but also breathable and moist, and it must be soft to touch.

Under such consideration, the hot air material of NEWBUSI is selected as the bottom layer. It is a kind of non-woven material with fine holes every where. The difference between water droplets and water vapor molecules is utilized to block water droplets in the diaper, and eliminate water vapor outside the diaper to achieve waterproof and breathable effect.

The hand touch feeling is also amazing, delicate and soft, can not help but stick with the cheek, too soft.

The bottom layer is delicate and soft which can be observed by eyes.



Details affect the comfort of the diaper

How to make the baby wear more comfortable?

Pengpeng cloud soft waist: not tight, gentle hug

Some babies may have this situation: find that the belly has red marks which is due to the waist circumference of the diaper is too tight, and the baby's belly is constricted.

In order to solve this problem, we have adopted the Pengpeng Cloud soft waist, whose inner layer is close to the baby's skin to securing the diaper effectively and providing a more comfortable fit. The outer layer is bubbly, and the hollow bubble layer is like a belt, which has a stronger pulling ability.



Laboratory lift effect:





With each time of stretch, the small bubbles expand greatly, and the ductility is very good



Double-layer leakproof design: not easy to leak wih any movements

Babies who are over 1 years old begin to develop big movements. They like to climb, walk, their meaty legs very like to swing. That causes a great challenge on the diaper's anti-leakage performance.

Whether the diaper will leak or not has big relationship with whether it is worn correctly. In order to prevent side leakage as much as possible, the double leak-proof design is adopted, and the softer and watertight NEWBUSI SMMSS non-woven material is added to the leg circumference of the lesbian pants.

The inspector pours a liquid simulating urine into the side circumference of the diaper, and it can be clearly seen that not a single drop of water has penetrated the anti-leakage layer.

Zoom in on the details, okay? Every drop of liquid is literally locked in his diaper.


Quality inspection

Experiments were carried out with copper sulfate solution

Test the diaper will separate out Super Absorbent Polymer or not.



After absorbing the copper sulfate liquid, the surface remains clear and refreshing:

On professional equipment. According to the dust standard map for detection:


In addition, there are many tests that cannot be described in detail due to space problems;

Check elastic tension:




To detect the retraction force of rubber bands after heat expansion:



Test the pH of your diaper

Ours are weakly acidic;



After testing in our factory laboratory, customers will also send the sample to the national authoritative testing agency for testing. After testing, no fluorescent agents, formaldehyde, can decompose carcinogenic aromatic amine dyes.



Coliform, Staphylococcus aureus, etc., are also not detected:



After many tests, get the achievement of a high-quality lesbian pants
