[0025] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0026] Reference Figure 1 and 2 , Figure 1 It is a structural cross-sectional view of the breathable bottom membrane of some embodiments of the utility model; Figure 2This is a structural overlay diagram of the absorbent block of some embodiments of the present invention.

[0027] The utility model provides a breathable base film of a sanitary napkin, comprising a breathable base film body 1, wherein the breathable base film body 1 comprises, from top to bottom, an isolation layer 2, a non-woven fabric layer 3 and a cushioning layer 4, wherein the isolation layer 2 comprises a plurality of absorbent blocks 21, and the absorbent blocks 21 are arranged in a matrix and covered on the non-woven fabric layer 3 to form the isolation layer 2, and the cushioning layer 4 comprises a plurality of cushioning blocks 41 covering the bottom of the non-woven fabric layer 3.

[0028] When the sanitary napkin is in use, a certain gap can be created between the base film and the underwear by adding the cushion layer 4 to facilitate the circulation and entry of air. In this way, there is no need to set grooves under the same layer of film to create a gap for air entry, which would make it thinner and cause the risk of easy penetration. The isolation layer 2 is arranged in a matrix through multiple absorption blocks 21. When the sanitary napkin is produced, a gap can be created with the layer on the top of the isolation layer 2, so that a gap is also created inside the sanitary napkin, which is convenient for air circulation. At the same time, the absorption blocks 21 can also absorb and increase the overall absorption rate of the sanitary napkin.

[0029] According to some embodiments of the utility model, the absorbent blocks 21 are optionally honeycomb-shaped, which can increase the softness and prevent the absorbent blocks 21 from shrinking when squeezed, affecting the comfort level, and also facilitate the absorption of the absorbent blocks 21, which can be made of cotton.

[0030] According to some embodiments of the present invention, the padding block 41 is optionally located in a position corresponding to the absorbent block 21. In this way, the gaps between the padding block 41 and the absorbent block 21 at the top and bottom of the non-woven fabric layer 3 can be located in a position corresponding to each other, so that the gaps at the top and bottom of the non-woven fabric layer 3 are relatively thin, allowing air to enter for ventilation.

[0031] According to some embodiments of the utility model, optionally, a plurality of grooves 31 are provided at the bottom of the non-woven fabric layer 3, and the grooves 31 correspond to the positions of the padding blocks 41. In this way, the positions where the absorbent blocks 21 and the padding blocks 41 are located at the top and bottom of the non-woven fabric layer 3 are relatively thin, thereby increasing air permeability to a certain extent, and the diameter of the grooves 31 will not be larger than the padding blocks 41, thereby preventing the padding blocks 41 from sinking into them.

[0032] According to some embodiments of the present invention, the cushioning layer 4 is optionally made of hydrophilic nonwoven fabric. The grooves 31 arranged in this way will make the thinned position of the nonwoven fabric layer 3 easy to penetrate, and the use of hydrophilic nonwoven fabric is also conducive to preventing its penetration.

[0033] According to some embodiments of the utility model, optionally, a glue layer 5 is provided at the bottom of the padding block 41. A separation layer is provided at the bottom of the padding layer 4 so that the separation layer is torn off during use to expose the glue layer 5 provided on each padding block 41 so that it can be adhered to the inside for fixing.

[0034] According to some embodiments of the utility model, optionally, negative oxygen ions are provided in the absorbent block 21 to increase the antibacterial effect of the sanitary napkin.

[0035] It should be understood that the embodiments disclosed in the present invention are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features understood by ordinary technicians in the relevant field.
