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.

 

Key Features

• Soft and Fluffy Texture: Smooth surface and excellent drape for comfort.

• Excellent Breathability: Open structure allows air circulation, preventing heat buildup.

• Chemical-Free Bonding: Hot air bonding uses no adhesives, ensuring safety and purity.

• High Uniformity and Strength: Even fiber distribution for stable physical performance.

• Skin-Friendly and Hypoallergenic: Perfect for hygiene and medical products.

• Eco-Friendly Options: Available in biodegradable cotton or eco-modified ES fibers.

 

Product Advantages of Hot Air Nonwoven Fabric

Hot air nonwoven fabric is produced by bonding fibers through controlled hot air circulation, allowing low-melting-point fibers to fuse without the use of chemical binders or high mechanical pressure. This process creates a fabric with a three-dimensional, fluffy structure, offering excellent softness, bulk, and breathability.

Compared with mechanically bonded or thermally calendered nonwovens, hot air nonwoven fabric maintains high loft and elasticity, making it particularly suitable for applications where comfort and cushioning are essential. The absence of hard bonding points also contributes to a smooth hand feel and uniform appearance.

For manufacturers, hot air nonwoven fabric offers a balance between lightweight structure, stable bonding, and gentle surface contact, especially in hygiene and comfort-focused products.

 

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.

 

Hot Air Nonwoven vs. Other Bonding Technologies – Application-Based Selection

Hot air nonwoven fabric is often compared with thermal-bonded or spunbond nonwoven materials, but each serves a different purpose.

Hot air nonwoven fabric is preferred when:

• Softness and bulk are primary requirements
• Products require cushioning or elastic recovery
• Skin comfort is more important than high tensile strength

Other bonding technologies may be more suitable where high strength, thin structure, or abrasion resistance is required. Hot air nonwoven fabric focuses on comfort-oriented performance, making it a strategic choice rather than a general replacement.

Understanding this distinction helps customers select the right material for the right function.

 

Functional Treatments & Structural Customization Options

Hot air nonwoven fabric can be customized to meet different functional and processing needs:

• Hydrophilic or hydrophobic treatment
• Soft-touch or skin-contact finishing
• Elastic fiber blending for enhanced resilience
• Customized basis weight and thickness
• Color, width, and roll format options
• Breathability and loft control

Weboss supports customers by fine-tuning fiber composition and bonding conditions to achieve targeted performance outcomes.

 

Common Applications of Hot Air Nonwoven Fabric

Thanks to its softness and bulk structure, hot air nonwoven fabric is widely used in:

• Hygiene products (diapers, sanitary napkins, adult care products)
• Absorbent core cover layers
• Medical and healthcare disposables
• Cushioning and padding materials
• Comfort layers in composite nonwoven structures
• Protective packaging and insulation layers

Its role is often to provide comfort, cushioning, and breathability rather than structural strength.

Specifications

FAQ—Frequently Asked Questions

Q1: What is the difference between hot air nonwoven fabric and other nonwovens?
A1: Hot air nonwoven fabric is bonded by hot air rather than glue or water jets, resulting in better softness and fluffiness.

Q2: What are the main types of hot air nonwoven fabric?
A2: There are two main types: ES hot air nonwoven (PP+PE or PET+PE) and 100% cotton hot air nonwoven fabric. The cotton type is softer and more eco-friendly but slightly higher in cost.

Q3: Is the fabric safe for direct skin contact?
A3: Yes. All materials are non-toxic, hypoallergenic, and tested for skin safety, making them suitable for baby and cosmetic products.

Q4: Can the GSM and width be customized?
A4: Yes, we provide customizable weight, width, and pattern designs based on customer requirements.

Q5: Do you support OEM or customized production?
A5: Yes. Shanghai Weboss New Material Technology Co., Ltd. offers OEM/ODM production, flexible order quantities, and international shipping service.
