Description

technical field

[0001] The invention relates to the field of sanitary products, in particular to an absorbent core of an absorbent product and a manufacturing process thereof. Background technique

[0002] Absorbent articles such as paper diapers and sanitary napkins are commonly used sanitary products. Generally, such absorbent articles consist of three main parts: a surface cover, an absorbent core, and a base fabric. The surface coating layer can also be called a coating layer or a water-permeable surface layer.
