Sanitary napkins are composed of outer covering materials, inner absorbent layers, leak-proof bottom films, etc. They are external physiological hygiene products for women to use during menstruation, formed by special packaging machines. Sanitary napkins, in terms of product structure, are mainly divided into three layers: The first layer is the surface layer, mainly made of non-woven fabric or perforated film, which serves to penetrate and isolate. The second layer is the absorption layer, which is accomplished by fluff pulp or dust-free paper for absorption. To enhance the absorption capacity of the product, some products are added with high-molecular water-absorbing resin. The third layer is the base layer, mainly made of polyethylene film, which can prevent leakage. Its back is coated with hot-melt adhesive, which serves a fixing function. Different classifications of sanitary napkins: By length, they are divided into daily-use, night-use and extended. According to the surface texture, it can be divided into dry mesh surface and cotton mesh surface. Sanitary napkins can be classified into regular sanitary napkins and medicated health care sanitary napkins, etc. Female friends can choose according to their menstrual flow and adaptability.
At present, due to the wide variety of sanitary napkins on the market and the uneven quality of products, consumers should pay attention to the following five aspects when purchasing and using them.
First, pay attention to distinguishing the appearance. The outer packaging of sanitary napkins should have the following markings: hygiene license number, production date, shelf life or validity period, standard number implemented, enterprise name and address, etc. The sealing of each outer package and individual small package should be smooth without any air leakage. A good sanitary napkin should have a clean surface, uniform thickness and undamaged sealing. In addition, in terms of hand feel, good sanitary napkins are made of highly absorbent and fluffy fluff, so they are light and soft. Try to choose sanitary napkins that have been produced recently.
The second is to choose high-quality products from large enterprises. The production environment of large sanitary napkin enterprises is relatively good, and their management is strict. They strictly monitor the physical properties and hygiene indicators. Choosing to use sanitary napkins from these large enterprises can relatively ensure safety. When purchasing sanitary napkins offline, it is best to choose large shopping malls or supermarkets. Large shopping malls and supermarkets have fast goods circulation, short storage time for sanitary napkins, good storage environment, and guaranteed hygiene and quality. When buying online, try to recognize official flagship stores or third-party supervised online platforms to prevent purchasing counterfeit or substandard products.
The third is to use sanitary napkins scientifically. A woman's menstrual period can be divided into three stages, and different types of sanitary napkins can be chosen and used according to these three stages. When the menstrual flow is heavy, the wing guard type should be used during the day and the night safety type at night. The standard type can be used in daily life. Ultra-thin or sanitary pads can be used before and after menstruation. This combination choice is, on the one hand, for safety and comfort, and on the other hand, to save on menstrual expenses.
Fourth, when choosing sanitary napkins, one should pay attention to their own feelings. At present, there are many types of sanitary napkins, including cotton-faced, mesh, scented and medicated sanitary napkins, etc. Generally speaking, the dry mesh surface sanitary napkins use a chemical fiber material called "perforated membrane", which is characterized by a relatively fast water permeability rate. However, chemical fibers may increase the risk of allergies. The cotton mesh surface is mostly made of non-woven fabric, which is extracted from cotton and is more natural and soft, suitable for the vast majority of women. In general, cotton-faced sanitary napkins absorb water quickly. The anti-seepage performance of the mesh surface is good. Appropriate medicated sanitary napkins have health care functions, etc. Therefore, you should choose the most suitable type for yourself based on your actual usage experience. Different sanitary napkins should be chosen for different seasons and usage needs. For instance, if you need to travel or take a long vehicle ride, it is advisable to use sanitary napkins with a dry surface to accelerate the absorption of menstrual blood, reduce the feeling of dampness and stuffiness, and lower the risk of infection. In relatively hot seasons, when the air is humid and hot and the human body sweats more, it is even more necessary to change the used sanitary napkins in time to keep the body comfortable. Women with a constitution prone to allergies should use medicated sanitary napkins with caution, as they may cause skin allergies, itching in the private parts and other symptoms.
Fifth, preventing "re-pollution" is of vital importance. Because human hands carry a large number of bacteria, when opening sanitary napkins, try not to touch the surface of the sanitary napkins with your hands to avoid secondary contamination. It is best to wash your hands before use.
