In some embodiments, the absorbent layer 3 is formed by forming a PP wood pulp spunlace 110 from a PP spunbond composite wood pulp spunlace, and attaching the super absorbent resin 120 to one side of the PP wood pulp spunlace 110. In the embodiment of the invention, the absorbent layer 3 is made of PP wood pulp spunlace non-woven fabric covered with super absorbent resin, the PP wood pulp spunlace non-woven fabric can be the combination of PP spun-bonded fabric and wood pulp spunlace non-woven fabric, and the super absorbent resin is arranged on one side (outer surface) of the PP wood pulp spunlace non-woven fabric. Wherein the super absorbent resin is attached to the PP wood pulp spunlace nonwoven fabric, for example, the super absorbent resin can be sprinkled on the outer surface of the PP wood pulp spunlace nonwoven fabric through a scattering bucket. Of course, in other embodiments, the super absorbent resin may be combined with the PP wood pulp spunlace nonwoven fabric in other manners, which is not limited in the embodiment of the present invention, as long as the super absorbent resin is stably disposed on the PP wood pulp spunlace nonwoven fabric. Further, as shown in fig. 1 or fig. 3, the PP wood pulp spunlace 110 in the absorbent layer 3 may be closer to the top sheet 2, and the super absorbent resin 120 in the absorbent layer 3 may be closer to the back sheet 4.
From this, through adopting PP wood pulp water thorn non-woven fabrics and super absorbent resin to combine the absorbent layer who forms mutually, increased the imbibition volume of anti-galactorrhea pad, the absorbing capacity is strong, the absorption rate is fast to guaranteed the dry and comfortable nature of anti-galactorrhea pad, still improved the comfort level that the anti-galactorrhea pad was worn, increased the market competitiveness of product.
It is to be understood that the shape and size of the absorber layer are not particularly limited by the embodiments of the present invention, and may be formed in various shapes and have desired sizes as needed. For example, the absorber layer can be circular in shape or designed to have various shapes according to actual needs. For example, the diameter of the absorber layer may be smaller than the diameter of the base layer, or the diameter of the absorber layer may be equal to the diameter of the base layer, in terms of size; further, the PP wood pulp spunlace nonwoven in the absorbent layer has a diameter equal to or slightly smaller than the diameter of the backsheet.
In some embodiments, the superabsorbent resin 120 is distributed on the PP wood pulp spunlace 110 in a gradient manner, and the grammage of the superabsorbent resin gradually decreases along the center-to-edge direction of the PP wood pulp spunlace. For example, as shown in fig. 4, in the embodiment of the present invention, the superabsorbent resin 120 is arranged on the PP wood pulp spunlace 110 in a divergent manner, and further, may be distributed in a gradient manner, and the grammage of the superabsorbent resin 120 gradually decreases along the direction from the geometric center of the PP wood pulp spunlace 110 to the edge of the PP wood pulp spunlace 110.
