In the production process of the sanitary towel, part of the product is polluted by bacteria due to factors such as environment, raw material processing and the like, but in the special product of the sanitary towel, the product needs to be disinfected in order to avoid infection of a user. At present, ethylene oxide is mainly used for disinfection in the industry, belongs to a broad-spectrum sterilizing agent, is in a gas state, can penetrate through articles with irregular shapes, destroys the internal structure of harmful bacteria, achieves the sterilization effect, and can kill various microorganisms including spores, tubercle bacillus, bacteria, viruses, fungi and the like at normal temperature. In addition, the articles sterilized by ethylene oxide can be wrapped and integrally packaged, and the aseptic state before use can be kept. The low-temperature disinfection process for ethylene oxide disinfection is quite common and popular in disposable nursing products, and has the process characteristics of low temperature, strong penetrating power, thorough sterilization and high safety, and the residual amount of ethylene oxide is less than or equal to 250 mu g/g when the products leave a factory in the national standard in order to prevent ethylene oxide gas from remaining in the products after ethylene oxide disinfection. The critical process parameters for ethylene oxide sterilizers are 4:
1. sterilization temperature;
2. relative Humidity (RH) at the end of the preconditioning phase;
EtO gas exposure time;
EtO concentration.
The above four seriously affect the sterilization effect, and different sterilization parameters need to be set for different products in the production process. In this regard, many domestic companies have studied the disinfection of sanitary napkins, for example:
the utility model discloses a sterilization and disinfection device on a sanitary towel production line, which is disclosed as CN 204484837U (published as 2015.07.22) in a Chinese patent library, and comprises a bracket, wherein a chain plate conveyor belt system is arranged on the bracket, a plurality of microwave cavities arranged in parallel are arranged in the middle of the upper end of the chain plate conveyor belt system, buffer bins are arranged on two sides of the microwave cavities arranged in parallel, a guide frame is arranged on one side of the buffer bin at an inlet, and a blower is arranged in the buffer bin at an outlet; an upper layer and a lower layer are arranged in the microwave cavity, the lower layer is a sterilization space, the upper layer is a ventilation and heat dissipation space, an axial flow fan is arranged in the upper layer ventilation and heat dissipation space, and a plurality of ultraviolet scanning sterilizing lamps arranged in parallel are arranged at the connecting layer of the sterilization space and the ventilation and heat dissipation space; the novel ultraviolet sterilization equipment is applied to a sanitary towel production line by adopting optimized structure distribution, and the sanitary towel is sterilized and disinfected, so that the production quality of the sanitary towel is improved.
