Baby Diaper

Less Mess
Disposable diapers have a very strong absorbent lining that can absorb wetness up to almost 5 to 6 times your baby pees. These diapers are designed in a way that makes them absorb the maximum amount of wetness, yet create the least amount of mess.

Keeps Baby Dry and Safe
Disposable diapers can absorb wetness and grow to almost 5 times their own weight, yet keep your baby dry. The lining that is placed in the centre often contains gel components that are guaranteed to absorb the wetness and keep the surface dry for almost 5 to 6 hours. Wet or moist skin encourages bacteria to feed and is the perfect breeding ground for bacteria, virus and other germs. When your baby wears a diaper, the sensitive area remains dry and thus the growth of bacteria and other germs is prevented.

Easy to Use
If you have ever tried making a young baby or toddler wear a cloth nappy, you can understand how difficult it is to have your baby sit still while you place the nappy underneath. After that, you also have to make sure that the nappy is placed properly and your baby is still, so that you can tie it up properly. With a disposable diaper, you can simply wrap it around your baby, even if your baby is standing up, and secure it at the sides with the Velcro straps. Of course you can also use the pant style diapers, which are super popular due to their ease of use. All you have to do is make your baby wear them as if you are putting on a pair of pants, and that is it.

Uninterrupted Sleep
When your baby sleeps in a nappy at night, you will have to constantly wake up and check for any signs of wetness. Not only will this disturb your sleep, your baby will also wake up each time, and you may have to do the entire bedtime routine all over again. Wearing a diaper at night will ensure that your baby feels nice and dry and can get uninterrupted sleep.

Formation of the Absorbent Pad
The absorbent pad is formed on a movable conveyer belt that passes through a long "forming chamber." At various points in the chamber, pressurized nozzles spray either polymer particles or fibrous material onto the conveyor surface. The bottom of the conveyor is perforated, and as the pad material is sprayed onto the belt, a vacuum is applied from below so that the fibers are pulled down to form a flat pad. At least two methods have been employed to incorporate absorbent polymers into the pad. In one method the polymer is injected into the same feed stock that supplies the fibers. This method produces a pad that has absorbent polymer dispersed evenly throughout its entire length, width, and thickness. The problems associated with method are that loss of absorbent may occur because the fine particles are pulled through the perforations in the conveyor by the vacuum. It is therefore expensive and messy. This method also causes the pad to absorb unevenly since absorbent is lost from only one side and not the other. A second method of applying polymer and fiber involves application of the absorbent material onto the top surface of the pad after it has been formed. This method produces a pad which has absorbent material concentrated on its top side and does not have much absorbency throughout the pad. Another disadvantage is that a pad made in this way may lose some of the polymer applied to its surface. Furthermore, this approach tends to cause gel blocking, since all the absorbent is on the outside of the pad. The moisture gets trapped in this outer layer and does not have a chance to diffuse to the center. This blockage holds moisture against the skin and can lead to discomfort for the wearer. These problems are solved by controlling the mixture polymer and fibrous material. Multiple spray dispensers are used to apply several layers of polymer and fiber. As the fiber is drawn into the chamber and the bottom of the pad is formed, a portion of the polymer is added to the mix to form a layer of combined polymer and fiber. Then more pure fiber is pulled on top to give a sandwich effect. This formation creates a pad with the absorbent polymer confined to its center, surrounded by fibrous material. Gel blockage is not a problem because the polymer is concentrated at core of pad. It also solves the problem of particle loss since all the absorbent is surrounded by fibrous material. Finally, this process is more cost effective because it distributes the polymer just where it is needed.
After the pad has received a full dose of fiber and polymer, it proceeds down the conveyor path to a leveling roller near the outlet of the forming chamber. This roller removes a portion of the fiber at the top of the pad to make it a uniform thickness. The pad then moves by the conveyor through the outlet for subsequent operations to form the competed diaper.

Preparation of the Nonwoven
Sheets of nonwoven fabric are formed from plastic resin using the meltblown process as described above. These sheets are produced as a wide roll known as a "web," which is then cut to the appropriate width for use in diapers. There is a web for the top sheet and another for the bottom sheet. It should be noted that this step does not necessarily occur in sequence after pad formation because the nonwoven fabrics are often made in a separate location. When the manufacturer is ready to initiate diaper production these large bolts of fabric are connected to special roller equipment that feeds fabric to the assembly line.
At some point in the process, stretched elastic bands are attached to the backing sheet with adhesive. After the diaper is assembled, these elastic bands contract and gather the diaper together to ensure a snug fit and limit leakage.

Assembly of the Components
At this point in the process there are still three separate components, the absorbent pad, the top sheet, and the backing sheet. These three components are in long strips and must be joined together and cut into diaper-sized units. This is accomplished by feeding the absorbent pad onto a conveyor with the polyethylene bottom sheet. The polypropylene top sheet is then fed into place, and the compiled sheets are joined by gluing, heating, or ultrasonic welding. The long roll is then cut into individual diapers, folded, and packaged for shipping.

The Core Key of Infant Diapers is the "Core"
The traditional core is mixed with fluff pulp and polymer water-absorbent resin. The diversion effect is good, the absorption performance is excellent, the water absorption is fast, and the water retention capacity is large. Composite core, clean paper + single-layer polymer material + non-woven fabric + single-layer polymer material + clean paper. Ultra-thin, the polymer is a single layer, and the overall expansion can be kept flat after absorbing water, and there will be no faults and lumps. The third type is the semi-core, that is, the fluff pulp and water-absorbent resin are laid under the thin composite core. This kind of core claims to combine the advantages of the first two, but it is actually a core solution to reduce costs and reduce the difficulty of the technology. If the baby is more active, it will pile up together, and the water absorption surface will become smaller. There will also be lump problems.

Baby Diaper Raw Material
Any excellent product is inseparable from high-quality baby diaper raw material, and the same is true for high-quality diaper produced by trusted baby diaper manufacturer. Diapers are personal products, and the baby's skin is very delicate, which requires very high quality material for the diapers. At present, baby diaper wholesale on the market are mainly made of non-woven fabrics, fluff pulp or dust-free paper, polymer water-absorbing resin, Velcro, PE film, elastic threads and other materials.
●Non-woven fabrics: The surface layer of infant diapers is basically non-woven fabrics. Non-woven fabrics can improve the air permeability inside the diapers, discharge moisture and heat in time, effectively reduce the chance of diaper rash, and are soft and comfortable, which are not irritating to baby's skin.
●Clean paper: The raw material of clean paper is wood pulp fiber, which has unique physical properties, such as high elasticity, softness, excellent hand feeling, excellent drape, extremely high water absorption and good water retention performance.
●Fluff pulp: Fluff pulp is a kind of wood pulp fiber. The fiber structure has a large number of irregular voids. After processing, it has super hydrophilic properties and can hold a larger amount of water.
●Polymer: Polymer water-absorbent resin can absorb water hundreds of times heavier than itself, and has a strong water-holding capacity, also known as super-absorbent or high-water-retaining agent.
●PE film: PE protective film is the simplest macromolecule organic compound. It is mainly used as the bottom film of newborn baby diapers. It is characterized by being breathable and watertight.
