Diapers are one of the essential baby products for modern parents, and the surface nonwoven fabric of diapers is a vital component. The surface nonwoven fabric directly contacts the baby's skin and has an important impact on comfort, breathability and moisture absorption. This blog will focus on the two main nonwoven fabric options for diaper surfaces: spunbond nonwoven farbic and hot air through nonwoven, so as to provide parents with more understanding and purchase guidance.
1. Production process:
-Spunbond nonwoven fabric:
Spunbond nonwoven fabric, also known as hot rolled nonwoven fabric, is made by spinning, hot rolling and cold rolling after mixing fiber staple fibers with adhesives. This process usually requires the use of petrochemical fibers as raw materials, such as polypropylene (PP) and polyester (PET). The production process of spunbond nonwoven fabric is relatively simple and low cost.
-Hot air through nonwoven fabric:
Hot air through nonwoven fabric is made by melt spinning process. In this process, the high-temperature molten polymer is sprayed into a high-speed airflow and quickly solidifies in the air to form a fiber web. This manufacturing process allows hot air non-woven fabrics to use a variety of raw materials, such as polypropylene, polyester, polyethylene, etc. Compared with spunbond non-woven fabrics, the production process of hot air non-woven fabrics is more complicated and the production cost is higher.
2. Comparison of characteristics:
1) Characteristics of spunbond nonwoven fabrics:
- Breathability: Spunbond nonwoven fabrics have good breathability, which can reduce moisture inside diapers and keep baby's skin dry.
- Softness: Spunbond nonwoven fabrics are soft to the touch and highly comfortable, suitable for baby's delicate skin.
- Hygroscopicity: Spunbond nonwoven fabrics have a certain degree of hygroscopicity, which can quickly disperse urine and reduce baby's discomfort.
2) Characteristics of hot air through nonwoven fabrics:
- Super strong breathability: The fiber diameter of hot air through nonwoven fabrics is thinner and has good breathability, which can effectively prevent stuffiness and odor inside diapers.
- High strength: Hot air through nonwoven fabrics have high tensile strength and tear strength, making diapers stronger and firmer.
- Fast moisture absorption: Hot air through nonwoven fabrics have larger fiber gaps and faster moisture absorption, which can quickly disperse urine and keep the baby's skin dry.
3. Price comparison:
Due to differences in production processes and characteristics, there are certain differences in prices between spunbond nonwoven fabrics and hot air nonwoven fabrics. Generally speaking, the price of spunbond nonwoven fabrics is relatively low, which is suitable for consumers who pursue cost-effectiveness. The price of hot air through nonwoven fabrics is higher, but it also brings better breathability and comfort, which is suitable for consumers who pay attention to quality and performance.
Whether choosing spunbond nonwoven fabrics or hot air through nonwoven fabrics as the surface nonwoven fabrics of diapers, they have their unique advantages. Spunbond nonwoven fabrics are suitable for consumers who pursue economical and affordable, providing good breathability and moisture absorption. Hot air through nonwoven fabrics are better in breathability, comfort and moisture absorption speed, which is suitable for consumers who pay attention to product quality and performance. When buying diapers, you can choose the right type according to your needs and budget. At the same time, it is recommended to check the product label before buying to understand the specific type and characteristics of non-woven fabrics, so as to choose the most suitable diapers for your baby.
