The present invention relates to a reusable sanitary napkin having excellent breathability and waterproofness. More specifically, the present invention has a superabsorbent fiber as a central absorbing means, and these fibers are wrapped with a cotton, a moisture-permeable and waterproof fiber, and wings are formed on both sides of the longitudinal direction. Fastening means are formed at both ends thereof to be easily fixed and maintained on the panties, and also to an eco-friendly reusable sanitary napkin that is easy to carry.

In general, sanitary napkins are widely used for the purpose of absorbing and treating women's menstrual blood, vaginal secretions, urine secretions of infants and adults, and the like, such as sanitary napkins, panty liners, diapers, and tampons. By the way, such a sanitary napkin is composed of a cover in contact with the skin, a non-woven fabric such as absorbent cotton, an absorbent sheet containing a polymer absorbent and a liquid impermeable cover. Although disposable sanitary napkins are convenient to use, they consist of an absorbent sheet and a liquid impermeable cover, which can cause odors from physiological substances as well as cause skin irritation when the blood stays in the absorbent layer for a long time. It can also cause various gynecological disorders. In addition, there are various side effects such as causing dysmenorrhea due to dioxin, bleach, etc. when using a conventional disposable sanitary napkin.

Therefore, in order to solve this problem, a reusable sanitary napkin made of natural cotton has been proposed. For example, Korean Utility Model Application No. 2004-0016333 describes, "The lower coating layer of the pure cotton woven cotton and the lower coating layer. A fixing base disposed on the sealing cloth and having a good breathability, and an upper coating layer of the pure cotton fabric disposed on the waterproof cloth and woven into a pure cotton, and having fixing means formed on both sides to be coupled to each other; Sanitary napkin is characterized in that it consists of a plurality of absorbent portion of the cotton fabric is sewn to be fixed to the woven cotton pure cotton, "Korean Utility Model Application No. 2005-0043504" in the sanitary napkin, The outer skin which fixed snap is attached to the wing parts of both sides, and the auxiliary absorbent fabric sew on the lower surface in the center Er, the inner skin of which the inner edge of the outer skin is sewn; the outer skin, the secondary absorbent fabric, and the inner skin are dyed natural fibers woven or knitted from natural materials with natural dyes, and the silver nanomaterial It is a natural fiber fabric coated with a coating, and the outer surface made of the natural fiber fabric is silver nano-processed natural fiber sanitary napkin, characterized in that the water-repellent treatment.

However, the above-mentioned devise solves the disadvantages of disposable sanitary napkins and has certain advantages, but it completely solves the convenience of carrying and the insufficient absorption and maintenance characteristics of menstrual blood, which is a problem raised in reusable sanitary napkins of cotton materials. It did not exist. Moreover, the above-mentioned conventional design describes that a waterproof fabric or a water-repellent outer sheath with excellent ventilation is used, but the specific configuration thereof is not clearly described, and thus, it does not provide sufficient breathability and moisture permeability and thus waterproofness. In the case of a large number of leaks outside the sanitary napkin or the moisture permeability and breathability, there was a disadvantage that does not completely solve the weakness of the skin.

Therefore, the present inventors, as a result of earnestly research to solve various problems in the above-described conventional sanitary napkins, devised the sanitary napkin configuration of the present invention to complete the present invention.

Accordingly, an object of the present invention is to provide a recyclable sanitary napkin made of natural fibers having a property of sufficiently absorbing and maintaining a large amount of menstrual blood and having excellent waterproofness with moisture permeability and breathability.
