Diapers are composed of four main parts:

① Surface layer non-woven fabric

② Conductive layer special non-woven fabric

③ Absorbent layer: toilet paper + fluff pulp + SAP

④ Bottom PE film or PE film + non-woven fabric

In addition, it is supplemented by adhesive fixing structure and three-dimensional leak-proof structure.

Nowadays, high-quality diapers are mainly composed of wood pulp and polymer materials. The polymer materials have the function of absorbing water hundreds to thousands of times heavier than themselves. After the polymer material absorbs water to form a hydrogel, it will become harder and start to form a ball (commonly known as lump), and the addition of wood pulp can keep the diaper as flat and soft as possible.

高分子材料吸水形成水凝胶后，会变硬并开始形成球状（俗称团块），加入木浆可以使纸尿裤尽可能保持平整和柔软。
