Wherein, the good use experience is judged as the good bacteriostatic and odor-removing effect.

TABLE 1

The comparison data show that compared with comparative examples 1-3, the animal blood absorption speed is higher, the reverse osmosis amount is lower, the surface layer is drier and comfortable, and the bacteria inhibition and the odor removal can be effectively realized in the examples 1-5; in comparative example 1, however, the absorption speed was slow and significant reverse osmosis occurred without the funnel member; in the comparative example 2, when the antibacterial factor is not added in the absorption layer, the number of people with good antibacterial and odor removing effects is obviously reduced; in comparative example 3, when the funnel part was not provided and the bacteriostatic factor was not added, the absorption performance was deteriorated, the reverse osmosis amount was increased, and the bacteriostatic and odor-removing effects were poor; in comparative example 4, when the absorbent material is prepared by mixing commercially available fluff pulp and super absorbent resin, and has no bacteriostatic factor and no funnel part, both the absorption performance and the bacteriostatic performance are poor; in comparative example 5, the surface layer was spun-bonded nonwoven fabric, and no perforation structure was provided, and when no funnel part and no bacteriostatic factor were present, not only the absorption performance was poor, but also no bacteriostatic effect was exhibited.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention. The invention has not been described in detail and is in part known to those of skill in the art.
