In addition, the front portion of the first absorbent core layer 11 in the length direction is a second straight stripe-shaped structure 112. In this embodiment, the front portion of the sanitary napkin is relatively less prone to side leakage, the design of the second straight bar-shaped structure 112 can ensure absorption, and at the same time, the production cost of the sanitary napkin is reduced, and in this embodiment, the front portion of the second straight bar-shaped structure 112 and the front end of the first straight bar-shaped structure are both provided with arc-shaped structures, so that the beauty of the sanitary napkin can be enhanced, and the folding of the sanitary napkin can be facilitated.
Wherein, the width of the second straight stripe structure 112 is equal to the width of the first straight stripe structure. In this embodiment, the production of the sanitary napkin and the attachment of the first core absorbent layer 11 and the second core absorbent layer 12 can be facilitated, and the stability of the connection between the first core absorbent layer 11 and the second core absorbent layer 1 can be further increased, it should be noted that the width of the first core absorbent layer 11 and the width of the second core absorbent layer 12 are equal to each other, which is only the optimal choice in this embodiment, and the condition that the two are different in size is also within the protection scope of this embodiment.
The face sheet 3 is provided with a three-dimensional cuff 6 for preventing menstrual blood from leaking out from the side of the face sheet 3. In this embodiment, the three-dimensional enclosure 6 is provided with a plurality of layers of leakproof and breathable non-woven fabric, so that the leakage of menstrual blood from the side of the face layer 3 can be further prevented, and the breathable non-woven fabric can ensure that the skin of a user is kept dry and fresh, thereby further increasing the comfort of the user.
In addition, the three-dimensional guard 6 is arranged at one end of the surface layer 3 and extends to the bottom edge of the leakproof breathable basement membrane 4 along the side edge of the surface layer 3. In this embodiment, the three-dimensional protective enclosure 6 is bonded to the edge of the surface layer 3 and the edge of the leakproof breathable bottom film 4 respectively through hot melt adhesive, so that menstrual blood can be prevented from overflowing from the side due to the fact that menstrual blood cannot be absorbed by the absorption layer 1 in time.
Example 2
In the present embodiment, as shown in fig. 2, the other end of the three-dimensional barrier 6 is provided with a rubber band 7 for defining the three-dimensional barrier 6. In this embodiment, the top of the three-dimensional enclosure 6 can be made to better fit the human body, and menstrual blood can be prevented from leaking from the top of the three-dimensional enclosure 6.
Example 3
In this embodiment, as shown in fig. 2, a bamboo fiber layer 8 for bacteriostasis is provided between the second absorbent core layer and the leakproof breathable basement membrane 4. In this embodiment, the bamboo fibre in the bamboo fibrous layer 8 has the moisture absorption antibacterial action, and the aseptic environment of assurance sanitary towel that can be fine has avoided sanitary towel to breed the bacterium when using, has guaranteed that the healthy needs of user's skin explain that other protective layers that have antibacterial disinfection action that are similar to bamboo fibrous layer 8 are all among the protection scope of this embodiment.
