Problems solved by technology

[0003] In recent years, with the continuous research and development of nano-antibacterial agents, new nano-antibacterial agents have been applied in the field of sanitary napkins. Among them, the application of nano-silver antibacterial agents is more common. It belongs to the category of inorganic nano-antibacterial agents and has good antibacterial performance. There are many related research reports. For example: the international invention patent "Tampon impregnated with nano-particles of two metals" (GB 2500305 (A)), the Chinese invention patent "a nano-silver far-infrared negative ion magnetic therapy sanitary napkin and pad" (CN102600021A), "a Production method of antibacterial non-woven fabrics and non-woven products" (CN 102191681A), "Nano Tampons" (CN 1539511A) and utility model patents "Liquid Nano Silver Antibacterial Sanitary Napkin" (CN 202859470U), "Nano Silver Antibacterial Hygiene Towels" (CN 202724123U), etc., have applied nano-silver materials to the field of sanitary napkins or tampons, and achieved good antibacterial effects. Ion precipitation produces pigmentation, and silver ions are likely to cause adverse effects on the environment and human health
The Chinese invention patent "A Nano Photocatalyst Antibacterial Sanitary Napkin" (CN 105268012 A) mainly uses titanium dioxide sol to spray non-woven fabrics, and the use environment of sanitary napkins is almost a dark environment, which greatly limits its catalytic effect. , simple spraying adhesion is not strong, there is a problem of titanium dioxide precipitation

Abstract

The invention discloses release-free antibacterial sanitary cotton, a preparation method and application and belongs to the technical field of sanitation supplies. According to the invention, under the synergistic effects of soluble metal salt, a crystal inducer, a crystal mineralizer, a crystal modifier and a crystal stabilizer and by controlling reaction conditions, nano microcrystal dispersions with the microcrystal size less than 5nm are obtained, then the nano microcrystal dispersions are effectively implanted into loose cotton fibers treated by weak base under certain conditions, crystals continuously grow and set under the heating condition, surface residues are removed, and then carding and combing processes are carried out by virtue of a cotton sliver carding machine, so that antibacterial sanitary cotton is prepared; and then compression molding is carried out, so that a sterilized sanitary cotton sliver is obtained. The sanitary cotton and the sanitary cotton sliver product which are provided by the invention have an efficient sterilization function, and no metal ion is released, thereby being safe and environment-friendly; and especially the sanitary cotton has obvious sterilization and antibacterial effects and can alleviate gynecological inflammation to a certain degree when being used as the sanitary cotton sliver.

Description

technical field [0001] The invention relates to the preparation and application of a tampon with no precipitation antibacterial function and belongs to the field of medical and sanitary products. Background technique [0002] Catheter-type tampons are favored by many people because they do not affect clothing and sports during use. European and American women use them more. In the United States, 42% of women use tampons. Because Asians do not like suppositories habitually, tampons are rarely used among women in Asian countries. In China, only 2% of women use tampons. The reason is that many women feel that tampons are not hygienic and worry about the introduction of bacteria into the uterus and cause infection, which may even lead to toxic shock syndrome. Because the tampon is in close contact with the vaginal epithelial cells, the body's resistance may be reduced. Due to the long interval between replacements, the endometrium is dry and cracked due to the absorption of the...
