To provide a liquid-absorbent, air-permeable sanitary napkin capable of effectively preventing leaching of menstrual blood on the premise of securing a good air-permeable state and greatly reducing the thickness.SOLUTION: The skin-contact drying layer 1, the air permeable liquid storage core layer 2, the SMS anti-water repellent nonwoven fabric layer 3 which is a polymer composite SMS nonwoven fabric layer and the bottom layer 4 are superimposed, and the skin-contacting dry layer 1 Is positioned on the absorption surface of the permeable liquid storage core layer 2, the SMS anti-water repellent nonwoven fabric layer 3 is positioned on the back surface of the permeable liquid storage core layer 2, and the bottom layer 4 is positioned on the absorption surface of the SMS anti-water repellent nonwoven fabric layer 4 It is located in the air. The SMS anti-water repellent nonwoven fabric layer 3 is positioned on the back surface of the permeable liquid storage core layer 2, thereby achieving the object of waterproofing, effectively preventing leakage of menstrual blood, waterproofing, blood blocking, permeation The thickness was greatly reduced by the premise that the three people coexisted, and the thickness was greatly reduced with a large liquid absorption amount, and the amount of menstrual blood absorption by the large absorption amount was improved.BACKGROUND OF THE INVENTION【課題】良好な透気状態を確保する前提で経血の浸出を効果的に阻止できると共に、厚さを大幅に低減することができる、液吸収性透気性生理用ナプキンを提供する。【解決手段】肌当接乾燥層1、透気性液貯蔵コア層2、高分子複合SMS不織布層であるSMS防血撥水不織布層3及び底層4を重ねて構成され、肌当接乾燥層1が透気性液貯蔵コア層2の吸収面に位置し、SMS防血撥水不織布層3が透気性液貯蔵コア層2の裏面に位置し、底層4がSMS防血撥水不織布層4の透気面に位置する。SMS防血撥水不織布層3が透気性液貯蔵コア層2の裏面に位置することで、防水の目的を達成すると共に、経血の漏れ出しを効果的に阻止し、防水、血阻止、透気といった三者が共存する前提で、厚さを大幅に低減し、また、大きい液吸収量で厚さを大幅に低減すると共に、大吸収量による経血吸収量を向上させた。【選択図】図1
