PROBLEM TO BE SOLVED: To provide a liquid-absorbing breathable sanitary pad which not only can effectively prevent the leakage of menstrual blood under the premise of guaranteeing a good breathable condition, but also can greatly reduce the thickness of the sanitary pad under the premise of greatly improving the comfort level in using the sanitary pad.SOLUTION: The sanitary pad comprises a skin-friendly dry layer 1, a breathable liquid-storage core layer 2, an SMS blood-resistant water-repellent non-woven fabric layer 3, and a bottom layer 4 in an overlapped manner. The skin-friendly dry layer 1 is located in the absorption surface of the breathable liquid-storage core layer 2, the SMS blood-resistant water-repellent non-woven fabric layer 3 is located in the back of the breathable liquid-storage core layer 2, and the bottom layer 4 is located in the breathable surface of the SMS blood-resistant water-repellent non-woven fabric layer 3. The SMS blood-resistant water-repellent non-woven fabric layer 3 is designed in the back of the breathable liquid-storage core layer 2, which achieves the object of water-proof, and effectively prevents the leakage of menstrual blood, so as to greatly reduce the thickness of a sanitary pad product under the premise of achieving the object of coexistence of water resistance, blood resistance, and breathability. Further, a polymer compound SMS non-woven fabric layer is designed, which greatly reduces the thickness of the sanitary pad with large liquid absorption amount, and increases the absorption amount to the menstrual blood with the large absorption amount.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】良好な透気状態を有すること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、使用上の快適度を大幅に向上させる前提で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こと。【解決手段】肌当接乾燥層1、透気性液貯蔵コア層2、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3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の裏面に設計され、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目的を実現する前提で
