[0015] The present application will be further described in conjunction with the drawings and specific embodiments.

[0016] As Figures 1-4 shown, the disposable absorbent article 1 of the present application has a longitudinal direction Y same as a length direction and a transverse direction X same as a width direction; the absorbent article has a skin side close to skin and a non-skin side away from skin when used. The absorbent article 1 comprises a liquid-permeable surface layer 11, a liquid-impermeable bottom layer 14 and an absorbent core 13 between the liquid-permeable surface layer 11 and the liquid-impermeable bottom layer 14.

[0017] A functional layer 123 is arranged between the absorbent core 13 and the liquid-permeable surface layer 11, the functional layer 123 is a solid or semi-solid functional material, the functional material is a skin care essence or a perfume, any known suitable material can be used, the functional layer has any one of the effects of covering odor, adsorbing odor and skin care.

[0018] Embodiment 1

[0019] The first water-soluble layer 121 is arranged between the functional layer 123 and the liquid-permeable surface layer 11. The first water-soluble layer is a material known in the art, which is composed of plant starch, gelatin and soft phospholipid. The water-soluble layer is soluble in water and stable in structure without water. By covering the functional layer 123 with the first water-soluble layer 121, the functional material is less likely to evaporate, and the loss of the functional material can be reduced. When excrements infiltrate, the water-soluble layer dissolves and releases the functional material, so that the functional material can better play its role. The first water-soluble layer completely covers the functional material and the skin side, and the width and length of the first water-soluble layer are both greater than those of the functional layer. The transverse width of the first water-soluble layer is 1 / 3-1 / 2 of the transverse width of the absorbent core.

[0020] Embodiment 2

[0021] To further reduce the evaporation of the functional layer, a second water-soluble layer 122 is arranged on the non-skin side of the functional layer 123, i.e. between the functional layer 123 and the absorbent core 13. The second water-soluble layer 122 has the same size and material as the first water-soluble layer 121, and the effect of inhibiting evaporation is improved. The functional material is arranged on the water-soluble layer, so that the risk of possible pollution of unnecessary areas caused by directly applying the functional material to the components of the absorbent article during production can be avoided.

[0022] Embodiment 3

[0023] The second water-soluble layer 122 and the first water-soluble layer 121 can be formed by the same water-soluble layer. After the functional layer 123 is arranged on the skin side of the water-soluble layer, the transverse sides of the water-soluble layer are folded onto the skin side of the functional layer 123.

[0024] Although the present application is specifically shown and described in connection with the preferred embodiments, those skilled in the art will appreciate that various modifications in form and detail can be made without departing from the spirit and scope of the application as defined in the appended claims.
