Referring to fig. 1 to 3, a strong absorption sanitary napkin 1 without reverse osmosis comprises a surface layer 2, a flow guiding layer 3, an absorption core 4 and a breathable basement membrane 5 from top to bottom; the surface layer 2 is a mixture layer of bamboo fibers and polylactic acid fibers, the flow guide layer 3 is a water-repellent coarse denier hot air cloth, the absorption core body 4 is provided with a groove 41, and the groove 41 and the surface layer 2 are suspended.

In the sanitary napkin 1, the surface layer 2 is a mixture layer of bamboo fibers and polylactic acid fibers, and preferably, the bamboo fibers and the polylactic acid fibers are mixed in a ratio of 4: 1. In the production process, the directly prepared bamboo fibers and polylactic acid fibers are mixed, processed into a net by a carding machine and reinforced by a spunlace process to obtain the bamboo fiber surface layer containing polylactic acid, so that the prepared fibers well combine the advantages of the bamboo fibers and the advantages of the polylactic acid fibers, not only the antibacterial property of the bamboo fibers is kept, but also better fiber strength and product softness are realized. The sanitary towel surface layer 2 has the effects of bacteriostasis, dryness, softness, moisture absorption and quick drying. More preferably, the surface layer 2 is provided with a plurality of funnel-type small holes 21, the upper part of the caliber of each small hole 21 is large, and the lower part of the caliber of each small hole is small, so that the reverse osmosis of menstrual blood is prevented to a certain extent, and the surface layer is dry and comfortable.

This application is through attaching the thick denier hot-blast cloth that the water was refused to the one deck below surface course 2, and behind the menses infiltration core layer, liquid can't ooze out toward the surface course again, and the thick denier hot-blast cloth that this layer was refused water can play certain prevention effect. The hot-air cloth can rapidly absorb body fluid and guide the body fluid into the lower absorption core body 4 as uniformly as possible, thereby keeping the skin dry and preventing the body fluid from leaking laterally.

The absorbent core 4 is provided with grooves 41 by means of a wood pulp and a polymer applied in a targeted manner. The grooves 41 are provided at the periphery from which menstrual blood flows, i.e., at the middle of the absorbent core 4, so that menstrual blood rapidly permeates through the topsheet 2 into the absorbent core. The grooves 41 are arranged to provide a slight overhang distance between the absorbent core and the facing layer. Therefore, after the menstrual blood reaches the absorption core, the surface layer and the menstrual blood are in a completely separated state, so that the surface layer can quickly recover the dryness and the smoothness of the surface layer, and the arrangement of the grooves in the core can prevent the female from harming the moist and bacteria breeding of the sanitary towel during menstrual period.

Preferably, in another embodiment, as shown in fig. 4, the grooves 41 in the absorbent core 4 are boat-shaped, with the middle having the protrusions 42, and the periphery of the protrusions 42 having the depressions, which can dry the facing layer and prevent the side leakage of menstrual blood. Furthermore, the absorbent core is provided with a plurality of tapered holes 43, and after the menstrual blood reaches the absorbent core 4, the menstrual blood can rapidly permeate into the core structure by the diversion grooves.

Preferably, the sanitary towel 1 is provided with wings 11 on both sides, the periphery of the sanitary towel is sealed by hot pressing and high temperature, and the back of the breathable basement membrane is provided with gum and release paper.

The application provides a sanitary towel, including outer ventilative antibacterial surface course, middle anti-water conservancy diversion layer and the water absorption polymer core that has the recess to and the ventilative basement membrane of bottom, realize the purpose that the sanitary towel moisture absorption is fast, dry and comfortable not moist, not anti-oozing through changing sanitary towel structure and material.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
