Jun 04, 2020
The main material of the sanitary napkin is cotton, non-woven fabric, paper pulp or polymer composite formed by the above materials. The side design is mainly used to prevent side leakage, because it will be used with the sanitary napkin At a certain angle, it is easier to rub against the leg base 2113, so the sanitary napkins with soft sides are more popular with women.
The adhesive of the sanitary napkin is impervious to water, which can keep the menstrual blood in the sanitary napkin. It is used to absorb the menstrual blood that flows out from the vagina during the menstrual period.
According to the national standard, sanitary napkins can be divided into three categories according to the surface material:
1. Dry mesh sanitary napkin
Refers to the sanitary napkin surface layer made 5261 using a variety of perforated film as the original sanitary napkin, which is mainly polyethylene, commonly known as PE film;
2. Cotton and soft sanitary napkins
Refers to the sanitary napkin made of various non-woven fabrics for the surface layer of the sanitary napkin, which is mainly polypropylene, commonly known as PP
3. Pure cotton sanitary napkins
Refers to the sanitary napkin made of pure cotton material for the surface layer of the sanitary napkin, which is mainly pure cotton non-woven fabric
The structure of sanitary napkins can be divided into surface layer, absorbent core and bottom layer
The layers of materials are bonded with hot melt adhesive.
The surface layer is the part that directly contacts the skin. Its material 4102 is soft. The surface weave and indentation can affect the reverse osmosis effect (dryness) of the sanitary napkin.
PE perforated membrane surface layer and cotton surface layer are the two most commonly used materials. PE surface layer with micro-porous design can make menstrual blood not easy to seep and make users feel dry, but the material is hard and some users will cause Allergic reactions; due to the improved cotton absorbency design, and the availability of perforated and composite materials, the market share in recent years has gradually been higher than that of PE sanitary napkins.
The inner layer is mainly composed of cotton, non-woven fabric, paper 1653 pulp or a composite of high-molecular polymer and high-molecular polymer composite paper, used to absorb the outflow of menstrual blood. The design of the side is mainly used to prevent side leakage, because it will show an angle with the sanitary napkin body during use, and it is easier to have friction with the groin. Therefore, the soft side sanitary napkin is more popular with women. The backing of sanitary napkins is impervious to material and can retain menstrual blood in the sanitary napkins. In the 70s and 80s, self-adhesive adhesives were developed to facilitate the fixing of sanitary napkins on underpants.
