Generally speaking, there are two kinds of diaper cores on the market, one is cotton core and the other is polymer core. Cotton core has fast infusion and fast absorption, the disadvantage is that it does not pack enough water. Polymer core, packing enough water, but the infusion and absorption speed is relatively slow. Composite core is a mixture of the advantages of two materials, with infusion speed, water absorption speed, packaging water volume and integrated core structure, fully meet the needs of walking stage babies. The role of composite core: break the traditional process, choose special composite materials, core absorption faster, stronger, not easy to break. Fully meet the needs of walking infants. Composite core production process: the first layer of dust-free paper, the second layer of polymer absorbent beads, the third layer of fluffy non-woven fabric, the fourth layer of polymer, the fifth layer of dust-free paper. Generally speaking, the diapers on the market are a combination of polymer and fluffy pulp, which are more likely to break, and the dust-free paper and polymer structure is not easy to break.

The third generation core is a composite core, and its structure is similar to sheet lamination. The composite core is relatively flat after absorbing water, without lumps and continuous layers.

Usually, dust-free paper and porous fluffy nonwovens are coated with a coating layer, then sap is spread between the porous fluffy nonwovens, and then each layer is bonded with hot-melt adhesive.
