Problems solved by technology

At present, there are many kinds of sanitary napkins with antibacterial and bactericidal effects, but the effect on women's care is uneven, and there are many sanitary products with poor antibacterial effects or even opposite effects.
[0004] Disclosed in the Chinese patent application 201010523910.X is a kind of warming sanitary napkin, which can produce a sense of warmth and has a layered structure with a top layer and a bottom layer. The mixed solution of ginsenoside produces a warm feeling when it comes into contact with the human body, and it is transmitted to the female uterus through the human body, which can continuously warm the uterus and relieve female dysmenorrhea. However, no attention has been paid to the strong reproduction of bacteria in female sanitary napkins during menstruation, which will affect the human body health problems
A sanitary napkin with health care function is disclosed in Chinese patent application 201711032479.7, which is characterized in that the extract of Chinese medicinal materials with antibacterial and health care effects is infiltrated into the core layer of the sanitary napkin. Sanitary napkins are contaminated and mildewed; the sanitary napkin disclosed in this application can remove peculiar smell when women use it, and has health care functions such as antibacterial, relieving dysmenorrhea, eliminating breast tenderness, and removing vaginal inflammation, but its water absorption and air permeability are poor. , but also does not have a warming effect
However, the main function of the sanitary napkin prepared by this application is only for sterilization, and has no effects such as keeping warm. Simultaneously, its comfort cannot be guaranteed, so there are still limitations.
[0005] So far, sanitary napkins have problems such as single function and uneven product quality. Therefore, there is an urgent need for a sanitary napkin preparation process, so that the prepared sanitary napkins have multiple functions, such as producing warmth, comfort, no stuffiness and dampness. At the same time, the sanitary napkin has strong water absorption, high air permeability, good sealing performance, safety guarantee, and good function of inhibiting the growth of bacteria and fungi

Abstract

The invention provides a sanitary towel preparing process, and relates to the technical field of hygienic products. A sanitary towel prepared through the process mainly comprises a water absorbing layer, a medicine layer, a fabric layer, a negative ion functional chip, an isolation layer, an aluminum-plated thin film sealed inner bag and a food-grade aluminum foil film outer bag. The water absorbing layer is prepared by cooling composite fibers, forming a net, conducting adhering, reinforcing, edge cutting and winding and filling in a super-water-absorbability material. The medicine layer is prepared by melting polyethylene and adding polyvinylpyrrolidone, ginger oil, vanillyl butyl ether, coco-betaine glyceride and edible decaldehyde-ethanol to be evenly stirred. The finally-obtained sanitary towel can generate warm feeling, has the effects of being comfortable, free of stuffy feeling and moist feeling, is high in water absorbability, high in breathability and good in sealing performance, gives the safety guarantees and has the good function of restraining the growth of bacteria and fungi.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a preparation process of sanitary napkins. Background technique [0002] Sanitary napkins have been popular in the Chinese market since the 1980s, and are widely accepted by women because of their convenience and ease of use. In western developed countries, women's sanitary napkins, as an important sanitary product, are managed by special departments and must be sold in special channels such as pharmacies, which can effectively avoid the pollution of sanitary napkins in the process of logistics and sales. But so far, my country has not reached such standards. Sanitary napkins have only been changed in terms of appearance design, while the phenomenon of common sanitary napkins carrying bacteria is very common, and they will suffer from secondary pollution in many links from production to consumption. There are great safety and health risks. [0003] Sanitary napkin is a...
