Why does the outer layer of diapers have a wet feeling when tearing down?

The outer breathable layer of diapers is made of special materials, which can lock urinating while releasing heat and moisture. The entire layer is covered with small holes that are invisible to the naked eye. These holes are allowed to pass the water such as water vapor, but completely block the channels such as liquid such as urination. So when the surface of the diapers feels humid, it is not the leakage of the urine, but the heat and moisture that has been released. Sometimes it may also have the smell of infant urine or poop. By increasing the breathability of diapers and preventing humidity, your baby will feel dry and comfortable!
