What is the difference between wood pulp core and composite core?

First of all, the wood pulp core is thick and can absorb very much, while the composite paper core is not so absorbent. For example, it is no problem for a baby to pee in a good composite paper core urine trouser pocket for 2-3 times, but it is thin. Usually, the thickness of the composite paper core diaper is only half of that of wood pulp. Of course, this is related to the parenting philosophy of different countries. Raise children in free range, choose those with good absorption performance, and raise children in captivity. A child is equipped with several adults. Different starting points and national conditions led to the invention of composite paper cores by the Chinese.
