Definition and characteristics of spunbond nonwoven fabric
Spunbond non-woven fabric is a type of non-woven textile that is made from high molecular weight compounds and short fibers through physical, chemical, and heat treatment processes. Compared with traditional woven textiles, non-woven fabrics have the following characteristics:
1. Spunbond non-woven fabric does not require spinning or weaving, with high production efficiency and low cost;
2. Spunbond non-woven fabrics can use different types of fibers, such as polypropylene, polyester, nylon, etc., and be processed to produce products with various properties;
3. Spunbond non-woven fabric is lightweight, breathable, and soft, and can be combined with other materials for use.
The role of spunbond non-woven fabric in sanitary napkins
1. Dry and comfortable: The surface of the sanitary pad is made of non-woven fabric, which can quickly transfer urine (blood) to the main absorption layer of the sanitary pad, keeping the surface of the sanitary pad dry and making women feel more comfortable.
2. Breathability: Spunbond non-woven fabric has good breathability, which can prevent odor and bacterial growth. At the same time, its breathability also helps to reduce the dampness in women’s private parts and lower the risk of developing genital diseases.
3. Fixed absorption layer: In sanitary napkins, spunbond non-woven fabric also serves as a fixed absorption layer. The absorbent layer is usually made of materials with strong water absorption, such as cotton, wood pulp, etc. This material with strong water absorption but insufficient softness requires the support of non-woven fabric to maintain the shape and stability of sanitary napkins.
Classification and application of non-woven fabric in sanitary napkins
Non woven fabric, as a multifunctional material, can be widely used in sanitary napkins. According to different purposes, in addition to spunbond non-woven fabrics, there are also various types as follows:
1. Hot air non-woven fabric: This non-woven fabric is commonly used on the surface of sanitary napkins. It uses polyolefin fibers, which are bonded after heating treatment, with a smooth, uniform surface and high softness.
2. Water jet non-woven fabric: This type of non-woven fabric is commonly used in the main absorbent layer of sanitary napkins. It uses various fibers such as polyester, polyamide, cotton, etc., which are made by high-speed water spraying and have the characteristics of strong absorption and good softness.
3. Melt blown non-woven fabric: This non-woven fabric is commonly used in the production of thinner products such as pads, daily and night sanitary napkins. It adopts hot melt technology, which melts the material and blows it during the spinning process, and has the characteristics of high strength, lightness, and good filtering effect.
Conclusion
In summary, non-woven fabric plays a very important role in sanitary napkins, as it can maintain dryness, breathability, and softness, while also fixing the absorbent layer of sanitary napkins. When choosing sanitary pads, female friends can choose the one that suits them according to their own needs to ensure their health and comfort.
