Hot Air Nonwoven Fabric

Product Overview

Hot air nonwoven fabric is produced by passing hot air through a layered web of fibers, which melts the low-melting-point component of the fibers and bonds them together. The resulting material is lightweight, elastic, and highly breathable, with a soft texture and uniform appearance.

Among them, ES (Ethylene-Propylene or Ethylene-Polyester) Nonwoven Fabric is made from bicomponent fibers such as PP+PE or PET+PE, while 100% Cotton Hot Air Nonwoven Fabric uses pure natural cotton fibers. Both types are safe for skin contact and suitable for a wide range of hygienic and medical applications.

Types of Hot Air Nonwoven Fabric

1. ES Hot Air Nonwoven Fabric (PP+PE or PET+PE)

   • Made from bicomponent fibers with a low-melting PE sheath and a PP or PET core.

   • Offers softness, uniform structure, and thermal bonding strength.

   • Commonly used in baby diapers, sanitary napkins, and mask inner layers.

2. 100% Cotton Hot Air Nonwoven Fabric

   • Made from pure natural cotton fibers, providing excellent moisture absorption, breathability, and skin comfort.

   • Fully biodegradable and eco-friendly, suitable for cosmetic and medical use, such as facial mask sheets, wipes, and pads.

   • Higher in cost compared to synthetic ES nonwoven fabrics due to the natural cotton content.

Production Process

1. Fiber Preparation:
   Fibers such as PP, PE, PET, or natural cotton are selected and blended.

2. Web Formation:
   Fibers are carded and laid evenly to form a smooth web.

3. Hot Air Bonding:
   Hot air passes through the fiber web to melt the low-melting fibers (like PE sheath) and bond the structure together.

4. Cooling and Finishing:
   The bonded fabric is cooled, softened, and wound into rolls.

5. Quality Inspection:
   Every roll undergoes strength, softness, and uniformity testing to ensure consistent performance.
