The prior paper diaper only can absorb urine and can not absorb blood clots during menstruation, so that the blood clots can not be absorbed in the using process of a user, and discomfort is caused. The invention changes the structure of the diaper to meet the nursing requirement of incontinence for women in menstrual cycle. The surface layer of the paper diaper is changed into the porous permeable layer with larger aperture, so that the menstrual blood can be better diffused downwards without remaining on the surface layer. Meanwhile, the core structure adopts a composite core, the deodorizing and antibacterial hydrogel freeze-drying material can absorb peculiar smell and deodorize, and the deodorant and antibacterial hydrogel freeze-drying material also has a good antibacterial effect, so that a user is more comfortable, and does not feel sultry and uncomfortable in the menstrual period. The bottom is a breathable basement membrane, so that the stuffiness feeling generated by a user in use is reduced.

The paper diaper often has peculiar smell in the using process, and the uncomfortable feeling of a user can be increased if the paper diaper is not removed in time. The yucca extract can inhibit the decomposition of urea in urine, so as to avoid the generation of peculiar smell from the source, and the volatilization characteristic of the plant essential oil has good deodorization effect on urine and menstrual blood. However, the plant essential oil is easy to volatilize and lose before the paper diaper is used, the plant essential oil is embedded in a polymer film prepared from the yucca extract and the chitosan quaternary ammonium salt by utilizing a microcapsule technology, the surface of the plant extract is condensed into microcapsules through electrostatic interaction of negative carboxyl groups in the yucca extract modified by maleic anhydride and positive quaternary ammonium groups in the chitosan quaternary ammonium salt, and then polyvinyl alcohol is added to form hydrogel, so that the binding tightness of the microcapsules is improved. And the addition of acrylamide and vinylpyrrolidone can promote the double crosslinking of hydrogel formation, and the reticular crosslinking structure can enhance the barrier property to urine or menstrual blood while improving the water absorption.
In addition, the freeze-dried hydrogel is crushed and then is in the form of freeze-dried powder, so that the absorption of urine or menstrual blood can be enhanced, the yucca extract contains both water-soluble groups and fat-soluble groups, so that the yucca extract has good binding property with the plant essential oil, and the microcapsule can be dissolved to release the plant essential oil in the using process of the paper diaper, and can slow down the release of the plant essential oil and improve the durability in use. And the tourmaline powder emulsion dipped in the tourmaline powder emulsion can carry ions, so that the tourmaline powder emulsion has antibacterial activity.
