Hot air-through nonwoven fabric is a type of nonwoven material produced by bonding fibers using hot air penetration. Here are its key uses and features:

Uses

1. Hygiene Products

u Baby diapers, sanitary napkins, and adult incontinence products (soft, absorbent, and breathable).

u Disposable wipes and dry/wet tissues.

2. Medical Applications

u Surgical gowns, masks, and medical drapes (lightweight and lint-free).

u Wound dressings and antibacterial pads.

3. Apparel & Home Textiles

u Insulation layers in clothing, quilts, or pillows (excellent thermal retention).

u Mattress padding and furniture upholstery (provides cushioning).

4. Filtration

u Air and liquid filters (porous structure traps particles effectively).

5. Industrial

u Wiping cloths, protective covers, and packaging materials.

Features

1. Softness & Comfort

Loftier and fluffier than spunbond or meltblown nonwovens, ideal for skin contact.

2. Breathability

High air permeability due to the porous structure.

3. Absorbency

Excellent liquid retention, often used in hygiene products.

4. Eco-Friendly

Can be made from biodegradable fibers (e.g., PLA) or recycled materials.

5. No Chemical Binders

Fibers are bonded thermally (e.g., using ES bicomponent fibers), reducing chemical residues.

6. Customizable

Adjustable thickness, density, and texture for specific applications.

Advantages Over Other Nonwovens

Cost-Effective: Faster production compared to needle-punched or hydroentangled fabrics.

Versatility: Combines softness with durability, suitable for disposable and reusable products.
