Furthermore, the first absorption layer 2 and the second absorption layer 3 are formed by sequentially overlapping a plurality of layers of breathable water absorption fabrics and sewing the breathable water absorption fabrics along the edges. The first absorption layer 2 and the second absorption layer 3 are made of soft skin-friendly water absorption cloth on the surface contacting with a human body, so that discomfort caused by skin friction is avoided, the absorption performance and the air permeability are good, and the problems of bacterial breeding caused by air impermeability, menstrual blood side leakage caused by water impermeability and the like are avoided. The first absorption layer 2 and the second absorption layer 3 are made of a plurality of layers of breathable water absorption cloth, and the first absorption layer 2 and the second absorption layer 3 are made of breathable water absorption cloth, so that the breathability and the absorptivity of the reusable combined sanitary towel are better. If the first absorption layer 2 and the second absorption layer 3 are made of cotton or other fillers, the phenomenon of caking and deformation and the like is easily caused after cleaning, the subsequent recycling of the reusable sanitary towel is influenced, the absorption effect is reduced, menstrual blood is not easily cleaned after being adsorbed on the fillers such as cotton, the cleaning is more convenient by adopting the cloth, the phenomena of caking, deformation and the like after cleaning can be avoided, the air permeability, the absorbability and the like can not be reduced in the recycling process, and the use effect is good. The first absorption layer 2 and the second absorption layer 3 are formed by being sequentially overlapped and sewn along the edge, stitches are tight and orderly, all thread ends and the like are hidden in the first absorption layer 2 and the second absorption layer 3, do not contact with a human body and do not rub the skin, and the comfort in the use process is ensured.

The waterproof breathable layer is made of TPU fabric with good breathability and waterproofness.

The surface of the bottom layer 1 contacting with the human body is evenly provided with air holes. Increasing the breathability of the bottom layer.

The length of the bottom layer 1 is 190-440 mm. The sanitary napkins are divided into daily use type sanitary napkins and lengthened night use type sanitary napkins because the sanitary napkins can not get up to replace during sleeping at night, and the menstrual blood is accumulated with time, and due to factors such as turning over, lying on side, changing sleeping postures, and the like, the sanitary napkins easily leak and stick to bed sheets or quilts, so that the sanitary napkins need to be used for a long time, and the sanitary napkins used for a long time in the daytime have the problems of resource waste, inconvenient movement and the like. When the length of the bottom layer 1 is 190-300 mm, the sizes of the first absorption layer 2 and the second absorption layer 3 are matched with that of the bottom layer 1, and the reusable combined sanitary towel is a daily-use sanitary towel and is used in daytime or when the menstrual blood amount is small; when the reusable combined sanitary napkin is used as a night sanitary napkin, the length of the bottom layer 1 is 300-440 mm, and the sizes of the first absorption layer 2 and the second absorption layer 3 are matched with that of the bottom layer 1, so that excessive blood overflow, side leakage and the like in the sleeping process are prevented. The length and thickness of the sanitary towel can be determined according to the self condition, the amount of menstrual blood and the like, and the sanitary towel with the length of daily use does not need to be used in the daytime and used at night.

Two ends of the bottom layer 1 in the length direction are arc-shaped with different widths. Because the wings are arranged at the position 8-20 mm above or below the horizontal central axis of the bottom layer 1, one end of the two ends of the bottom layer 1 in the length direction is closer to the wings, the end of the bottom layer 1 in the length direction closer to the wings is a front end, and the end of the bottom layer 1 in the length direction opposite to the front end, which is farther from the wings, is a tail end. When in use, the front end is arranged at one end close to the front of the human body, and the tail end is arranged at one end close to the hip of the human body. Since the menstrual blood flow-out portion is closer to the buttocks, the length of the tail end with respect to the flap is longer than the position of the tip end with respect to the flap, and the width of the tail end is wider than the width of the tip end, in order to prevent side leakage and improve absorption. When the reusable combined sanitary towel is used as a night sanitary towel, the protective wings are arranged at one quarter to one third of the length of the bottom layer 1, one end closer to the protective wings is a front end, and the other end farther away from the protective wings relative to the front end is a tail end. In order to prevent that menstruation blood overruns at night absorbs, side leakage etc, the utility model relates to when using sanitary towel night than the utility model discloses a when using sanitary towel the tail end compare with the length of flap is longer, the width of tail end compares the utility model relates to when using sanitary towel daily the width of tail end is big to reach better absorption effect.
