What are the differences in the thickness of absorbent materials for baby diapers?
Diapers are made of polymer water absorbent resin. The thickness of diapers is also different. The thin air permeability will be better, and the thick water absorption will be stronger.
What are the differences?
The function of infant diapers is to make babies safer and more comfortable. All kinds of diapers on the market are dazzling. We must be clear about the functions of various diapers and the similarities and differences in materials.
Diapers are basically made of high molecular absorption factor. The scientific name of water absorption factor and water locking factor is polymer water absorption resin. It is a new type of polymer, which can absorb water hundreds to thousands of times its weight. It is non-toxic, harmless, pollution-free, and has strong water absorption capacity. Under loading conditions, it can obtain high molecular weight polymer rarr through acrylic acid polymerization; High water retention rate, balanced absorption under load. The water absorption can not be simply extruded in a physical way, and can repeatedly release and absorb water.
The improvement of diaper quality is mainly due to the use of polymer water absorbent resin.
1. High water absorption: it can absorb non-ionic water hundreds or thousands of times its own weight.
2. Super water absorption: hundreds of kilograms of non-ionic water can be inhaled in 30 seconds per gram of super water absorption.
3. High water holding capacity: when the colloid after water absorption is under pressure, water will not be squeezed out easily.
4. High expansibility: after absorbing water, the super absorbent resin will expand hundreds of times rapidly.
5. Adsorption performance: the molecular structure of low crosslinked polyacrylate super absorbent resin contains carboxyl anion, which can be absorbed in the presence of ammonia and has obvious deodorization effect.
Usually, you can't wear pants until your child is one year old. After the baby can walk, it needs to be trained to urinate and urinate. At this time, it is more appropriate for the baby to wear pull-up pants, which is equivalent to wearing a thick pair of underwear for the baby, which can not only exercise the baby to walk, but also avoid peeing pants. Some people will think that the size of water absorption depends on the thin thickness of diapers. In fact, it is not. Many diapers on the market are relatively thin and contain a lot of water absorbent, which has strong suction. Some diapers are thicker, but there are more fluff pulp. This type of diapers will not increase the absorption rate, but will increase the thickness of diapers, and the absorption, softness and comfort will deteriorate accordingly. After children urinate, the urine can not be quickly absorbed by the permeable layer, and the small ass will be soaked in the urine and wet. The thicker the diapers, the more uncomfortable the baby will be. So for the thin thickness of diapers, it's better to be thinner and wear them more comfortably& nbsp;
The air permeability of diapers is mainly affected by material, structure, technology and other factors. The air permeability of diapers mainly depends on the air permeability of diapers, so timely replacement of diapers is the key to air permeability. Mothers who have many years of experience in purchasing sanitary napkins will take it for granted that the principle of diapers and sanitary napkins is the same. Therefore, when selecting diapers for their baby, the thinner the diapers, the better, so as to avoid the baby's red ass, inflammation and infection to the greatest extent. Although in terms of comfort, it must be thinner, more comfortable and breathable, and the baby can move more freely, it must depend on what the water absorption factor in the material is, how much it contains, and whether it is up to standard. As for mothers who think diapers are thicker, they feel the same way because they don't understand the material principle of diapers. In fact, thick diapers don't necessarily absorb water& nbsp;
Therefore, the choice of diapers depends on the details, not just on the thickness.
