hot air nonwoven fabric

Hot air nonwoven fabric, belonging to a type of non-woven fabric, has become an indispensable material for diapers due to its high fluffiness, good elasticity, soft hand feel, strong warmth retention, and good breathability. It is generally used for the surface or bottom layer of diapers. 1.Application of bottom layer of diapers The function of the bottom layer of diapers is to prevent urine from seeping out, so the material used for the bottom layer not only needs to have the characteristics of anti-seepage, low fuzzing, and good strength, but also needs to have a fabric like soft touch and wear resistance. Due to its soft and fluffy characteristics, hydrophobic airthrough nonwoven can be used as a bottom layer for diapers when combined with PE film. Therefore, in recent years, many diaper products have switched to using hot air non-woven fabric as the bottom layer. Hot air non-woven fabric is made of ES short fibers and greatly reduces pilling by adding ironing rollers and other processes, becoming a new choice for diaper bottom layer materials. 2.Application of surface layer of diapers There are generally two types of surface materials: adhesive non-woven fabric and hot air non-woven fabric. Hydrophilic airthrough nonwoven is more suitable as a surface material for diapers due to its high fluffiness, good elasticity, soft hand feel, strong warmth retention, and excellent breathability and permeability. It can not only effectively penetrate water, but also prevent urine from refluxing, improving the comfort of babies.

white hot air plain hydrophilic nonwoven fabric is an ideal material widely used in key areas such as the surface or absorbent layer of sanitary napkins. White hot air plain non-woven fabric is a new type of fiber network structure material made of high polymer materials such as polypropylene and processed through special processes. After the fibers are combed into a web, this material uses hot air from a drying device to penetrate the web, allowing it to be heated and bonded to form non-woven fabric. Due to its special production process, hot air non-woven fabric has the characteristics of softness, comfort, water absorption and moisture removal, strong stability, and hygiene and environmental protection.     In sanitary napkins, the application of white hot air plain hydrophilic non-woven fabric is mainly reflected in the following aspects: Firstly, its soft and comfortable characteristics make sanitary napkins more comfortable to wear, without causing excessive friction and irritation to the skin. This material has fine fiber fineness and a soft touch, which can provide women with a better wearing experience. Secondly, airthrough hydrophilic nonwoven fabric has good moisture absorption and breathability. Sanitary napkins need to be able to quickly absorb menstrual blood and keep the outside dry to reduce discomfort. This non-woven fabric material can quickly absorb and lock in blood while maintaining breathability, helping the skin breathe and reducing the irritation of secretions to the skin. This moisture absorbing and dehumidifying function allows sanitary napkins to remain dry and comfortable for a long time during use.     In addition, the white hot air plain hydrophilic non-woven fabric has strong stability and will not deform due to water or other factors. This ensures that sanitary napkins can maintain their original shape during use and will not deform due to moisture absorption, thereby affecting their effectiveness. In addition to the above advantages, hot air nonwoven fabric also has the characteristics of high fluffiness and good elasticity. This enables sanitary napkins to better adapt to the needs of different women in the design and manufacturing process, providing a more personalized user experience.  

Spunbond nonwoven fabric, hot air nonwoven fabric and thermal bond nonwoven fabric can all be used as the topsheet materials of diapers, and they each have different advantages and disadvantages. The following is a detailed analysis of these three materials:   1. Spunbond nonwoven fabric Advantages: Spunbond nonwoven fabric has high strength, good elongation at break and tear strength, which makes diapers less likely to break during use. Spunbond nonwoven fabric is relatively thin, which helps to reduce the overall weight of diapers and improve the comfort of wearing. Disadvantages: Compared with hot air nonwoven fabric, spunbond nonwoven fabric is slightly inferior in softness and breathability, which may cause a certain friction to the baby's delicate skin and affect breathability. 2. Hot air nonwoven fabric Advantages: Hot air nonwoven fabric has high fluffiness and elasticity, which makes the surface of diapers fit the baby's skin better and provide better comfort and wrapping. Hot air non-woven fabrics are soft to the touch and will not cause excessive friction on the baby's skin. At the same time, they have good warmth retention and are suitable for use in colder environments. Hot air non-woven fabrics have good air permeability and water permeability, which helps keep the inside of the diaper dry and reduce the risk of red bottom. Disadvantages: Low strength and easy deformation: The strength of hot air non-woven fabrics is relatively low and it is easy to deform during pulling, so more frequent changes may be required to maintain the integrity of the diaper.   3. Thermal bond non woven fabric   Advantages: The production process of thermal bond non woven fabric is relatively mature and the cost is low, so the price is relatively affordable. Disadvantages: Hard feel and average breathability: Compared with hot air non-woven fabrics, thermal bond non woven fabric may feel slightly harder and have average breathability, which may not be suitable for babies with high comfort requirements. (Note: Thermal bond non woven fabric is relatively rarely used on the topsheet of baby diapers, and are more commonly used in the medical and health fields. The reason for mentioning them here is to provide comprehensive information.)   Summary: When choosing the surface material of diapers, you need to consider factors such as the baby's skin condition, activity level, and seasonal changes. If the baby has delicate skin and requires high comfort, you can choose hot-air non-woven fabrics as the surface of diapers; if the baby has a large amount of activity and needs stronger mechanical support, you can choose spunbond non-woven fabrics as the surface of diapers. At the same time, you also need to pay attention to the frequency of diaper changes and cleaning care to keep the baby's skin healthy and comfortable.
