Disclosed is a hygienic product for menstrual periods and a manufacturing method thereof. Cores (4, 15, 21) of the hygienic product for menstrual periods made of a water-absorbing material are wrapped with an outer sleeve (8) made of a water-proof material, and can be put into the vagina partly or completely. The cores (4, 15, 21) absorb menstrual blood in the vagina though an opening or an open pore (14, 24) on the outer sleeve (8). The outer sleeve (8) is soft and flexible, is comfortable to use, and does not cause the walls of the vagina to lose water and dry out. The part left outside of the vagina is small and does not have the problems of ventilation, side leakage and impeding movement. The cores (4, 15, 21) have an electronic chip (30) inserted therein, which, after becoming soaked with menstrual blood, can automatically send signals to an intelligent terminal of a user, so as to remind the user to replace the hygienic product in time. The manufacturing method of the hygienic product for menstrual periods uses a hydrophilic material to make the cores (4, 15, 21). A limiting pin (5) is pasted onto the surface of the cores (4, 15, 21). The cores (4, 15, 21) are put into a forming mold of the outer sleeve which is injected with a liquid impermeable material, heated and solidified. The manufacturing method can also comprise embedding micro-electronic chips (28, 30) into the cores (4, 15, 21).Linvention concerne un produit hygiénique destiné aux menstruations et son procédé de fabrication.
