DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] Embodiment 1: refers to FIGS. 1-3. a liquid-absorbing breathable blood-resistant no-leakage sanitary pad consists of skin-friendly dry layer 1, breathable liquid storage core layer 2, SMS blood-resistant water-repellent non-woven fabric layer 3, and bottom layer 4 in an overlapped manner; wherein skin-friendly dry layer 1 is located in the absorption surface of breathable liquid storage core layer 2. SMS blood-resistant water-repellent non-woven fabric layer 3 is located in the back of breathable liquid storage core layer 2, and bottom layer 4 is located in the breathable surface of SMS blood-resistant water-repellent non-woven fabric layer 3. SMS blood-resistant water-repellent non-woven fabric layer 3 consists of a layer of SMS blood-resistant water-repellent non-woven fabric or multiple layers of SMS blood-resistant water-repellent non-woven fabrics in an overlapped manner. The bottom surface of bottom layer 4 is sprayed with back adhesive tapes 5 at intervals. The two sides of bottom layer 4 are sprayed with wing adhesive tapes 5 at intervals. Skin-friendly layer 1 may be a spunlaced non-woven fabric or a perforated non-woven fabric, or a perforated film. The manufacturing method of the liquid-absorbing breathable blood-resistant no-leakage sanitary pad is the prior art, and is not described in details by text herein.

[0011] Breathable liquid storage core layer 2 consists of high polymer resin layer 201 and dust-free paper 202 in an overlapped manner, and high polymer resin layer 201 is on dust-free paper 202. The top surface of breathable liquid storage core layer 2 is skin-friendly dry layer 1 and SMS blood-resistant water-repellent non-woven fabric layer 3. That is, SMS blood-resistant water-repellent non-woven fabric layer 3 is located in the back of dust-free paper 202 in breathable liquid storage core layer 2.

[0012] The gram weight of the SMS blood-resistant water-repellent non-woven fabric is 14 to 200 g/m.sup.2.

[0013] Embodiment 2: on the basis of the embodiment 1, SMS blood-resistant water-repellent non-woven fabric layer 3 is the polymer compound SMS non-woven fabric layer. The polymer compound SMS non-woven fabric layer consists of the first layer of SMS blood-resistant water-repellent compound non-woven fabric 301 and high polymer resin layer 302, and the second layer of SMS blood-resistant water-repellent compound non-woven fabric 303 in an overlapped manner, wherein high polymer resin layer 302 is located between the first layer of SMS blood-resistant water-repellent compound non-woven fabric 301 and the second layer of SMS blood-resistant water-repellent compound non-woven fabric 302, and the forming manner of high polymer resin layer 302 can be shaped by laying, and can also be shaped by spraying or spraying coating.

[0014] Embodiment 3: on the basis of the embodiment 2, because the dust-free paper has high elastic force, is soft, and has excellent hand feeling and vertical sense, and has extremely high hygroscopicity and good water holding capacity, the present application can use the dust-free paper to replace high polymer resin layer 302, and the dust-free paper is located between the first layer of SMS blood-resistant water-repellent compound non-woven fabric 301 and the second layer of SMS blood-resistant water-repellent compound non-woven fabric 302, so that a trace of the menstrual blood exuded from breathable liquid storage core layer 2 is absorbed by the dust-free paper that will lock in the trace of the exuded menstrual blood to prevent further extravasation.
