XX 60S replacement Nuoe NR610S is coming, core diapers can not be separated from him, you know

In the past, Nuoer Bio showed the significance of Nuoer Bio's initial dryness, medium-term dryness and long-term dryness in the use of diapers, performance points and initial, medium-term and long-term dryness, and emphasized that for the fluff-free structure diapers, If you want to achieve the best experience in the use of diapers, you need to consider the entire process of use of the core diaper. For any diaper to achieve the best experience, it is necessary to consider the entire use of the diaper, but the functionality of some velvet structure diapers due to the presence of a large amount of fluff pulp, in the core diaper needs to be carefully considered. In general, the design concept of the fluff pulp diaper and the core diaper is different. The optimization of the performance of the core diaper needs to be re-started from the most basic function of the diaper source.

The main content of this paper is to introduce the biggest difference in the principle of liquid absorption between core diapers and fluff pulp diapers, and how to achieve the same function of different absorbing principles. The trend of thinning of diapers has spawned core diapers. The difference in structure and material selection between core diapers and fluff pulp diapers determines the difference in the principle of liquid absorption. The biggest difference is that there is not a large amount of fluff pulp present in the core diapers ( There is also a small amount of wood pulp in the dust-free paper, but no matter the form or quantity, it can not play the role of a large amount of wood pulp in the wood pulp diaper. The difference between the two principles of liquid absorption is mainly reflected in the initial stage of liquid absorption, and it needs to start from the function of wood pulp.

In the 1990s and at the beginning of this century, the company introduced the principle of the initial pipetting principle of diapers in the 1990s and the beginning of this century, and can summarize the role of fluff pulp in the initial pipetting.

Figure 2. Description of the effect of wood pulp on P&G's 2002 patent

In Fig. 1, it is described that the flow rate of urine can reach 15 to 20 ml per minute, and when the flow rate of urine significantly exceeds the absorption speed of the absorbent body, leakage of urine may occur. Figure 2 indicates that in wood pulp diapers, the absorption speed of the water absorbing resin is generally lower than that of the urine. The wood pulp acts as a "temporary reservoir", and the urine is temporarily stored until the water absorbing resin will completely urinate. After smoking.

Therefore, in wood pulp diapers, wood pulp plays an important role in the initial stage of diaper absorption. However, in the core diaper, this "temporary reservoir" does not exist substantially, and the wood pulp diaper absorbs the initial wood pulp. The function, in the core diaper, needs to be completely completed by the water absorbing resin, and the absorption speed of the water absorbing resin is fast enough to match the flow rate of the urine. This reason causes the performance of the suitable water absorbing resin in the domestic core diaper to be significantly different from the performance of the water absorbing resin in the foreign fluff pulp diaper. At the same time, this is also the reason for the birth of Nuoer Bio NR610S.

Nuoer Bio's NR610S, with its superior initial liquid absorption capacity, significantly reduces the initial tidal sensation of the diaper and significantly reduces the possibility of diapers leaking. The initial aspiration and anti-leakage ability of the diaper is well reflected in the initial dryness test in the Nuoer Biodiaper Test Company Standard.Nuoer Bio combines the core of Japan*Daya and Japan* friends in the core diaper, Japan*Daya and Nuoer Bio NR610S, and the core upper and lower layers of Japan*Daiya core diapers carry the Nuoer bio diaper company standard diaper The test of dryness, the test results are shown in Figure 3.

The results show that the Nuoer NR610S brings a significantly better initial dryness to the diaper than the Japanese *Da absorbent resin, which is close to the Japanese* 60S. There are two problems in the initial dryness reaction of the diaper. One is how fast the diaper absorbs quickly in the early stage, and on the other hand, whether the absorption speed of SAP in the diaper can reach the moment of fixing the urine without leaking urine. NR610S makes the core diapers have excellent initial dryness and significantly reduces the risk of leaking urine. If the absorption curve is used to indicate the initial aspiration process of the diaper, the three combinations will have significant differences, and the second most popular aspiration. The curve is shown in Figure 4.

Nuoer NR610S reduces the initial tidal sensation of diapers by the instantaneous absorption capacity of saline and urine, and makes the initial tidal sensation of diapers quickly return to the stimuli threshold limit that does not cause discomfort to the baby, reducing the possibility of red buttocks. . At the same time, the rapid absorption capacity of the diaper on the urine reduces the urine to the three-dimensional protection, the oil migration on the surface of the non-woven fabric, and the test of the rubber band and the rubber band, which significantly reduces the risk of leaking urine.

In addition, the NR610S's instantaneous absorption capacity of urine significantly improves the initial absorption of the diaper, and optimizes the distribution of urine in the diaper, which is also beneficial for the mid-stage dryness (intermediate back bleed) of the diaper. The mid-return bleed of all Japan*Daiya core diapers, the upper Japanese*Daiya lower Japanese* friend core diapers, and the upper Japanese*Daya lower Nuoer NR610S diapers are shown in Figure 5.

Regardless of the initial liquid absorption curve of the diaper, the initial dryness of the diaper, and the mid-term dryness, the Noor NR610S has reached the level of Japan's 60S. In addition, for the Japanese * Friends 60S, its real advantage is the absorption capacity of saline or urine, rather than the mass of pure water absorption, the latter is very misleading, and the former is the choice of many core diapers The real reason for the 60S. Through the long-term research on the mechanism of liquid absorption in core diapers, Nuoer Bio has developed a NR610S instant-absorbing polymer that is extremely close to the level of Japan's 60S.

On the whole, NR610S is a good product developed by Nuoer Bio from the function of diapers, which has outstanding performance and significantly improved the experience of core diapers. It can significantly reduce the risk of leakage of diapers and improve dryness.
