Problems solved by technology

And the sanitary napkins in the prior art have the following disadvantages: 1. Women are easily infected during the menstrual period. In the prior art, some sanitary napkins have a bactericidal function, but after 24 hours of use, the bactericidal rate can be It reaches more than 99%, and in the actual use process of women, a piece of sanitary napkin is usually replaced within 4 hours. Therefore, the sanitary napkin in the prior art does not meet the sterilization requirements at all, especially does not have safe and rapid sterilization. function of

Embodiment 1

[0013] The screening of embodiment 1 antibacterial polypeptide obtains

[0014] Through the ginseng genome sequence obtained in the previous screening, small open reading frames with potential coding functions were found, and the corresponding amino acid sequences were translated from these small open reading frames, and antibacterial peptides were screened from them using three-dimensional structure analysis software, and the antibacterial peptides screened according to the prediction The peptide sequence was synthesized by solid-phase synthesis method, and the C-terminal was amidated, and the N-terminal did not contain methionine, and the antimicrobial peptide was prepared, and the corresponding functional verification was carried out. After screening, 22 antibacterial peptides were obtained, named WSJ- 1 to 22. Their sequences are respectively shown in SEQ ID NO: 1-22.

Embodiment 2

[0015] The effect verification of embodiment 2 antimicrobial peptides

[0016] The WSJ-1 polypeptide was dissolved in distilled water to a concentration of 2 mg / ml, and the antibacterial activity was detected by the agarose diffusion method. The strains used in the agarose diffusion method were Chlamydia trachomatis, Staphylococcus aureus, Neisseria gonorrhoeae, Leukorrhea, and Candida albicans. After the strains were revived, they were inoculated in the corresponding medium and cultured overnight, and then 50 microliters of the bacterial liquid were spread on the solid medium. After standing still and absorbing the bacteria-carrying liquid, add 10 microliters of polypeptide solution with a concentration of 2 mg / ml respectively. After culturing at 37°C for 16 hours, observe the presence and size of the inhibition zone. At the same time, observe whether the antibacterial zone changes within a week, and judge the length of antibacterial time. The results are shown in Table 1....

Embodiment 3

[0022] The preparation of embodiment 3 sanitary napkins

[0023] Immerse the multifunctional chip layer in an aqueous solution of polyethyleneimine, the concentration of polyethyleneimine in the aqueous solution is 5-10mg / ml, containing 0.14mol / LNaCl, reciprocating and oscillating for 40 minutes, and polymerization will be formed on the inner and outer surfaces of the new sheet. Object bottom layer; Place 100mL mass percent concentration then and be 0.01% 4, the methanol solution of 4'-diphenyldithiol was reacted for 5 hours, the chip layer after the reaction was vacuum-dried after fully soaking with methanol, and SeqIDNO: The antimicrobial peptide of 1 is reacted under the action of horseradish peroxidase and hydrogen peroxide respectively, and the chip layer of surface-bonded antibacterial peptide is obtained. The multi-functional chip layer is arranged under the non-woven fabric layer, the first dust-free paper is arranged under the multi-functional chip layer, and the poly...

Abstract

The invention discloses an antibacterial sanitary napkin, which comprises a non-woven fabric layer, a multi-functional chip layer, a first air-laid paper, a polymer absorbent paper, a second air-laid paper and a breathable PE film, wherein the multi-functional chip layer is coated with a bactericidal peptide layer. The sanitary napkin has an effect of killing bacteria in a short time. The product has the advantages of low cost and good effects and is worthy of large scale popularization and use.

Description

technical field [0001] The invention belongs to the field of disposable sanitary products, in particular to sanitary napkins for women. Background technique [0002] Due to endocrine effects during menstruation, women's body functions undergo various changes, resulting in reduced systemic and local resistance. If you do not pay attention to menstrual hygiene, it is easy to cause acute and chronic diseases, and even affect women's health and fertility. The role of sanitary napkins is to absorb menstrual blood and septum. Antibacterial sanitary napkins can keep the genitals clean, prevent gynecological diseases, and reduce skin itching, redness and swelling after using sanitary napkins. [0003] Sanitary napkin is a kind of absorbent material, the main material is cotton, non-woven fabric, pulp or high molecular polymer composite paper formed by the composite of the above materials, and the design of the side is mainly used to prevent Side leakage, because it will be at an a...
