In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

The invention provides a dry, bacteriostatic and odor-removing adult diaper in a first aspect, which comprises a diaper main body, for example, as shown in fig. 1, the diaper main body sequentially comprises a surface layer, a bacteriostatic and odor-removing filter core layer, an absorption core layer (also referred to as an intermediate absorption core layer) and a bottom film layer from top to bottom; the surface layer is provided with a flow guide embossing (not shown in figure 1); the antibacterial odor-removing filter core layer is formed by wrapping super absorbent resin, honeysuckle powder and wormwood powder by non-woven fabrics; the absorption core layer consists of an absorption layer and a wrapping layer wrapping the absorption layer, the absorption layer comprises a first absorption layer and a second absorption layer, and the first absorption layer is closer to the bacteriostatic odor-removing filter core layer than the second absorption layer; the first absorption layer is a high-water-absorption resin layer formed by high-water-absorption resin, and the second absorption layer is a mixed layer formed by mixing fluff pulp and the high-water-absorption resin; the superabsorbent polymer contained in the first absorbent layer accounts for 6 to 15% (e.g., 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, or 15%) of the total mass of the absorbent layer, the superabsorbent polymer contained in the second absorbent layer accounts for 11 to 20% (e.g., 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15%, 15.5%, 16%, 16.5%, 17%, 17.5%, 18%, 18.5%, 19%, 19.5%, or 20%) of the total mass of the absorbent layer, and the fluff pulp contained in the second absorbent layer accounts for 65 to 75% (e.g., 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, or 75%) of the total mass of the absorbent layer. The wrapping layer is not particularly required in the present invention, and for example, the absorbent layer may be fully wrapped or half wrapped with the wrapping layer, and for example, a half wrapping method as shown in fig. 1 may be employed in consideration of cost.

Present adult diaper is with two cotton core structures (little cotton core and big cotton core) many, and what comparatively dry and comfortable is that contain the polymer in little cotton core (going up cotton core), for saving the big cotton core of cost does not have the polymer, and more polymers are put in and are gone up the cotton core purpose: the local absorption capacity is increased, the high molecules are utilized to the maximum, the upper-layer core body is very easy to agglomerate and break in the using process of the adult paper diaper due to the fact that the upper-layer high molecule content is high (generally higher than 30%), and the existing adult paper diaper generally has the problem of poor dryness and comfort due to the fact that the urine quantity of a user is large and the using time is long.

The adult diapers manufactured in examples 1 to 10 were subjected to performance tests, and the results of the performance tests are shown in table 1.

The performance test method comprises the following steps: adding liquid into an iron ring by using a funnel, taking 150mL three parts of 0.9% saline, adding liquid at 0min, 10min and 35min respectively, recording the time of completion of each absorption as an absorption speed in unit of s, recording the diffusion length of the previous two times in unit of cm, testing the moisture sensation by using 10cm x 10cm absorbent paper at 15min, recording the weight increment of the absorbent paper as the moisture sensation in unit of g, and testing the reverse osmosis amount in unit of g by using 5kg of filter paper with the diameter of 15.00cm at 25min and 50 min.

The odor removing test method comprises the following steps: randomly 30 persons were found to perform the odor test, and the data results were counted, and the results are shown in table 2.

Table 1: the results of the performance test of the adult diapers of examples 1 to 10.

Table 2: the results of the odor removing effect test of the adult diapers of examples 1 to 10.

According to the results in tables 1 and 2, it can be seen by comprehensive analysis and comparison of data that the adult diaper prepared in example 1 has the fastest absorption speed, better dryness and the best odor removing effect. In addition, according to the results of the embodiment 1 and the embodiment 2, the invention unexpectedly discovers that the arrangement of the bacteriostatic odor-removing filter core layer not only has good bacteriostatic odor-removing effect, but also can effectively increase the liquid absorption speed and the diffusion length of the adult paper diaper to a certain extent, and effectively reduce the damp feeling and the reverse osmosis amount of the adult paper diaper, and the technical effect is obtained by the arrangement of the bacteriostatic odor-removing filter core layer in the invention. In the invention, comparing the embodiment 1 with the embodiments 4 to 7, it can be seen that in the bacteriostatic odor-removing filter core layer, only when the super absorbent resin is 0.3 to 10 parts, the honeysuckle powder is 0.2 to 5 parts, and the wormwood powder is 0.2 to 5 parts, the bacteriostatic odor-removing filter core layer can enable the bacteriostatic odor-removing effect to be optimal while not affecting comprehensive performances such as liquid absorption performance, dry performance and the like of the dry bacteriostatic odor-removing adult paper diaper. In the present invention, comparing example 1 with examples 8 to 9, it can be seen that the structure of the absorbent core layer in the present invention is configured such that the total mass of the super absorbent resin contained in the first absorbent layer is controlled to 6 to 15%, the total mass of the super absorbent resin contained in the second absorbent layer is controlled to 11 to 20%, and the total mass of the fluff pulp contained in the second absorbent layer is controlled to 65 to 75%, and the super absorbent resin content contained in the first absorbent layer is less than the super absorbent resin content contained in the second absorbent layer, so that the dry, bacteriostatic and odor-removing adult diaper having the best overall performance such as low reverse osmosis, liquid absorption performance, diffusion performance, and dry and refreshing properties can be obtained. In the invention, comparing the embodiment 1 with the embodiment 10, compared with the diversion embossing in the prior art, the diversion embossing formed by the embossing roller with the bulges with the specific width and the specific intervals among the bulges has better diversion effect, improves the infiltration speed of liquid and the effect of quickly spreading the liquid, increases the utilization rate of super absorbent resin, improves the absorption speed of the adult diaper, and obviously reduces the reverse osmosis amount and the damp feeling.
