Background
The origin of tampons can be traced to the beginning of the 20 th century, when women have limited choices of sanitary products in their physiology, and cloth, cotton or other materials are commonly used to address menstrual afflictions. At the beginning of the 1900 s, more modern catamenial devices began to appear on the market with the arousal of female consciousness and concerns about health. In 1919, the U.S. nurse, archur h.mcgolan, invented an earliest tampon. The product adopts a strip cotton material, can be inserted through vagina, and provides better comfort and concealment for women.
The material of the sanitary cotton sliver is mainly cotton, artificial fiber or a mixture of the cotton and the artificial fiber, the sanitary cotton sliver has the same size as 1 cm to 1.9 cm in diameter, and cotton threads (pull ropes) are attached to the tail end of the sanitary cotton sliver. The arc degree of the tip of the sanitary cotton sliver is different from one brand to another, so that a user can choose according to the use habit of the user. Tampons have been an integral part of the current market over centuries as a convenient, comfortable feminine hygiene product. The sanitary cotton sliver not only improves the life quality of women in the physiological period, but also promotes the promotion of public health consciousness and the attention of society to the health problem of women to a certain extent.

Dissolving chitosan in acetic acid solution, heating in water bath, fully stirring until the chitosan is completely dissolved to obtain chitosan solution, then adding N, N-methylene bisacrylamide, performing ultrasonic dispersion, then adding polyaspartic acid, ammonium persulfate and tetramethyl ethylenediamine, stirring for reaction to obtain hydrogel, dipping the hydrogel into non-woven fabric, and then drying to obtain the modified non-woven fabric.
Preferably, the mass ratio of the chitosan to the polyaspartic acid to the N, N-methylene bisacrylamide is (10-30)/(20-40)/(1-2).
Preferably, the temperature of the water bath heating is 45-55 ℃.
Preferably, in the step S1, the mass ratio of the cotton fiber to the modified fiber is (50-75): (20-40).
