Diapers, as a must-have "care tool" for mothers, have become one of the most concerned baby products for mothers because of their close proximity to baby skin and long-term use.

 

However, when faced with numerous diaper brands on the market, mothers are in endless distress. What kind of diapers are the most suitable for babies? Today, the editor will start with an in-depth analysis of the "core", one of the materials of diapers, to guide parents to choose diapers correctly.

 

 

The core key technology of diapers is the "core". The core absorption layer is composed of fluff pulp and water-absorbing crystals (abbreviated as SAP, also called polymers). Fluff pulp is made from trees and comes from natural materials, while SAP polymers are made from petroleum extracts and belong to petrochemical materials.

 

 

After absorbing a large amount of water quickly, the water-absorbing crystals expand into soft gel-like substances. The fluff pulp builds a three-dimensional internal space of the diaper with the help of fibers. It plays an important role in balancing water absorption in the entire process of water absorption and water locking. It can ensure that the water will not be completely absorbed by the local water-absorbing crystals instantly, causing the diaper to bulge, but gradually transition to the entire diaper to ensure balanced water absorption.

 

 

Many mothers equate thinness with breathability, blindly pursuing thin diapers, thinking that the thinner the better, and taking it for granted that the thinner the better. Let me ask, the plastic belt is very thin, but is it breathable?

 

 

In fact, the key to whether diapers are breathable or not is not the thickness, but whether the surface material and the material used in the absorption layer are breathable. It takes about 5g of fluff pulp to absorb 1g of water-absorbing crystals. Therefore, in order to make diapers thinner, in addition to reducing the total amount of absorbent layer materials, it is necessary to increase the proportion of water-absorbing crystals and reduce the proportion of fluff pulp, that is, to reduce the proportion of pure natural materials. The breathability of water-absorbing crystals is far inferior to that of fluff pulp.

 

Making diapers thin is the current global industry development trend, but this is actually for environmental protection considerations, not because the thinner the better. Therefore, don't blindly pursue "thinness". The breathability of diapers has no direct relationship with thickness. The key lies in whether the selected materials are breathable.

 

 

I believe that many mothers have seen such diaper evaluation experiments, but I would like to ask all mothers, if you have just washed your face with facial cleanser, without applying any skin care products, don't you feel that your skin is very dry and uncomfortable?

 

Since our skin needs to be moisturized, why do we require diapers to be as dry as possible? There must be mothers who ask, is it okay for diapers to be wet and damp? But in fact, diapers that are too dry or too wet are unhealthy for baby's skin.

 

Diapers must keep the baby's skin moist, which is similar to the state when we just wiped it with a towel after washing our hands. Diapers that are too wet can cause rashes, while those that are too dry can easily cause skin itching and allergies (some diapers are too dry and have to add moisturizer ingredients to relieve them to reduce the occurrence of allergies).

 

 

 

We mentioned above that water-absorbing crystals have a water absorption capacity far exceeding their own volume. During long-term use, unsaturated water-absorbing crystals can also absorb trace amounts of moisture from the skin. When there is enough fluff pulp around it to accumulate sufficient moisture, the water-absorbing crystals can continue to absorb moisture from the fluff pulp.

Therefore, a sufficient proportion of fluff pulp can protect the normal moisture of the baby's skin without excessive dryness. This is also the reason why some diaper brands add moisturizing moisturizers, just like we often need to apply body lotion in winter.

 

 

The baby never stops for a moment, either rolling around or kicking his legs. After taking off the diaper, wow, it's so flat! But... is this really good?

 

The fluff pulp fiber builds the internal space of the diaper, and the water-absorbing crystals become particles after absorbing water and swelling. What can keep these materials motionless? Smart mothers think about it, why can the diaper be so flat after the baby's large amount of activity? Have any careful mothers taken apart and looked at the diapers used by their babies?

 

 

This is because chemical ingredients are added to the diapers to "glue" the materials inside the diapers, so no matter how the baby moves, the used diapers are still flat. Although such diapers look very thin, they are not breathable. Many merchants actually sell them at a discount because of this advantage.

 

 

The ratio of fluff pulp and water-absorbing crystals in the core absorption layer of diapers is a very scientific value that requires precise calculation. High-end diaper brands also need to consider it from the perspective of dermatology and undergo skin pathology testing. Therefore, for diapers, the most important thing is not simply dryness and flatness or blind pursuit of thinness, but the ratio of fluff pulp and water-absorbing crystals in the core absorption layer.
