FIG. 1 is a schematic representation of the structure of a fibrous facing layer for an absorbent article provided with a differential hydrophilic gradient.
Fig. 2 is a schematic structural view of an absorbent article.
Detailed Description
Referring to fig. 1 and 2, the present invention is realized as follows: an absorbent product with a hydrophilic gradient difference comprises a liquid-permeable surface layer, a liquid-impermeable side leakage-proof layer 2, a liquid-impermeable bottom layer 3 and an absorbent layer 4. Specifically, the liquid-permeable top sheet is provided with a fibrous top sheet 1 for absorbent articles having a poor hydrophilic gradient, namely: the difference in the hydrophilic gradient is present between one side (top layer) of the fibrous top sheet 1 for absorbent articles, which is close to the human body, and the other side (bottom layer).
The difference in the hydrophilic gradient of the fibrous top sheet 1 for an absorbent article is carried out by: the fibrous top sheet for absorbent articles comprises a fibrous web top sheet 11 and a fibrous web bottom sheet 12, wherein a first hydrophilic coating layer 13 is provided on the fibrous web top sheet 11, and a second hydrophilic coating layer 14 is provided on the fibrous web bottom sheet 12, however, the coating thickness of the first hydrophilic coating layer 13 is smaller than that of the second hydrophilic coating layer 14, so that a hydrophilic gradient difference is formed between the first hydrophilic coating layer 13 and the second hydrophilic coating layer 14, and the fibrous top sheet 1 for absorbent articles provided with the hydrophilic gradient difference is obtained.
In a specific embodiment, in particular: the coating thickness of the first hydrophilic coating layer 13 is 0.01 to 0.1g/m2E.g. 0.03g/m2.
