Problems solved by technology

[0002] Sanitary napkins are sanitary products used by women during menstruation. There are many sanitary napkin products on the market at present. During menstruation, women's resistance will be reduced, and menstrual blood will also have some strange smell. The uterine waste that is not excreted in the uterus during menstruation cannot be disposed of. It will easily cause bacteria to grow in women's private parts, causing a series of gynecological diseases. Most of the antibacterial sanitary napkins on the market produce some chemical bactericides to achieve the bactericidal effect, but these chemical bactericides are not only poor in bactericidal effect, but also It also produces allergies, and long-term use will also destroy the balance of colonies in women's private parts
[0003] In response to this problem, the applicant developed an antibacterial liquid, applied it to pearl non-woven fabrics, and used the pearl non-woven fabrics to prepare sanitary napkins with long-lasting antibacterial and antibacterial properties, and applied for related patents, patent No. CN111749014A, this kind of sanitary napkin has good antibacterial effect, and has no effect on the performance of textiles and no harmful substances are produced, and is environmentally friendly and safe. However, it is found during use that its antibacterial performance will decrease The reduction may be due to the fact that the temperature of the sanitary napkin during use is slightly higher than the usual temperature, which reduces the antibacterial performance; during use, according to consumer feedback, sometimes there will be side leakage, mainly because the non-woven fabric general hydrophilicity

preparation example Construction

[0043] In one embodiment, the preparation method of the modified chitosan A comprises the following steps:

[0044] (1) Tributylmethylammonium bis(trifluoromethanesulfonyl)imide salt is heated to 40° C., and then chitosan is added to stir and react for 2 hours to obtain feed A1;

[0045] (2) add glutaraldehyde and stir 30min after waiting for material A1 to be cooled to room temperature to obtain material A2;

[0046] (3) The material A2 was ultrasonicated for 15 minutes to obtain the modified chitosan A.

[0047] The pearl non-woven fabric in the present invention is the pearl non-woven fabric of PP material, but because the pearl non-woven fabric of PP material does not contain hydrophilic groups, the hydrophilicity of the pearl non-woven fabric is poor, and the use of this When a sanitary napkin is prepared from a pearl non-woven fabric, the solution causes side leakage and other phenomena. At present, many sanitary napkins on the market have the phenomenon. It is used in...
