Double-layer Hot Air Through Diaper Nonwoven Fabric Raw Materials

1. Main application areas

(1) Baby diapers/pull-up pants
Top Sheet: Direct contact with baby skin, the softness and breathability of the hot air non-woven fabric reduce the risk of rash, and the high fluffiness enhances comfort.
Diversion layer: Some designs use hot air non-woven fabric to promote rapid liquid penetration and avoid reverse osmosis.
Waist circumference/side wings: Elastic hot air non-woven fabric provides a soft fit and prevents creases.
(2) Female hygiene products (sanitary napkins, pads)
Surface material: Hot air has no cilia and is skin friendly, suitable for sensitive skin. Some products enhance dryness and feel through embossing technology.
Back layer breathable film composite: used in combination with breathable film to balance leak prevention and breathability.
(3) Adult incontinence products
Absorbent core wrapping layer: The high-strength hot air non-woven fabric (such as SMS structure) prevents fiber shedding while maintaining breathability.
Stereoscopic enclosure: combined with elastic materials to prevent side leakage.
(4) Medical protective pads/bed pads
Disposable mattress surface: The antibacterial modified version of the hot air non-woven fabric can be used in medical scenarios, balancing comfort and hygiene.

2. Core advantages
Soft and fluffy: Fibers are bonded by hot air instead of chemical adhesives, making them more suitable for sensitive areas.
Good breathability: The porosity between fibers is higher than that of spunbond non-woven fabric, reducing the feeling of stuffiness.
Cost controllable: The production process is simple and suitable for large-scale production.
Customizability: By adjusting the fibers (such as ES fibers, polyester/viscose blends), the performance (water absorption, strength, etc.) can be changed.
