The incontinence articles of examples 1 to 12 and comparative examples 1 to 6 were each subjected to performance testing in the present invention, and the results of the performance testing are shown in Table 1.

The first test method comprises the following steps: the absorbent articles of examples and comparative examples were fed with a funnel, 80mL portions of 0.9% saline were fed at 0min and 10min, respectively, the time for completion of each absorption was recorded as absorption rate in s, the diffusion length of the first two times was recorded in cm, filter paper having a diameter of 11.00cm was used 5min after each feeding, and 3.5kg was pressed for 3 min, and the reverse osmosis amount was measured in g.

And a second test method: and randomly selecting 20 persons, wearing the incontinence articles for trial, and judging the antibacterial deodorizing effect and the cooling effect.

TABLE 1

From the above comparative data, it is seen that the incontinence articles of examples 1 to 3 have a faster liquid absorption rate, a lower reverse osmosis level, excellent antibacterial deodorizing effects when the liquid level is large, and excellent leakage-preventing effects (side leakage and back leakage prevention), and can give a cool and comfortable feeling to people; in example 4, when the amount of the super absorbent resin in the absorbent core is lower than the above range and the content of the dust-free paper and the bulky nonwoven is higher than the above range, the liquid absorption rate of the absorbent article is lowered, the reverse osmosis amount is increased, and the dryness of the top sheet is further affected; in example 5, when the absorbent core does not adopt the structure of the present invention, the liquid absorption rate of the absorbent article is also lowered and the amount of reverse osmosis is increased; in example 6, when the perforated structure of the first flow guiding layer is circular, the reverse osmosis amount of the flow guiding layer increases compared to the funnel shape, resulting in a decrease in dryness of the surface layer; in embodiments 8 and 9, when the first and second diversion layers are both hot air non-woven fabrics or one of the first and second diversion layers is hot air non-woven fabrics, both the liquid guiding performance and reverse osmosis performance of the diversion layers are deteriorated; in examples 10 and 11, if only the two sides in the longitudinal direction of the absorbent core are provided with the slits or only the two sides in the width direction of the absorbent core are provided with the slits, the liquid absorption speed, the choke effect and the antibacterial deodorizing effect of the absorbent core are adversely affected. In comparative example 1, when the absorbent core does not adopt the structure of the present invention but adopts a fluff pulp and super absorbent resin composite structure which is common in the market, deterioration of the absorbent performance, dry performance of the absorbent core is caused; when the absorption core in the comparative example 2 is not compounded with the antibacterial factor, the absorption speed of the absorption core is not greatly influenced, and the absorption core has no antibacterial and odor removing functions; in comparative example 3, when no nip is provided in the absorbent core and no antibacterial factor is compounded, the absorbent article prepared is not only slow in liquid absorption speed, but also has no leakage-proof function and antibacterial and deodorizing function.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the 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 scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention. The invention is not described in detail in a manner known to those skilled in the art.
