Polyester Nonwoven Fabric
Introduction:
Polyester nonwoven fabric is a type of material made from polyester fibers (mainly polyethylene terephthalate, PET) that are bonded together by physical or chemical methods rather than being woven or knitted.
Unlike traditional textiles, it does not require spinning or weaving processes, making it cost-effective and versatile.
Manufacturing Processes：
Common production methods include:
| Type | Process Principle | Characteristics |
|---|---|---|
| Needle-punched Nonwoven | Fibers are mechanically entangled by barbed needles | Thick, durable, breathable |
| Thermal-bonded Nonwoven | Heat rollers melt and bond fibers together | Smooth surface, high strength |
| Spunbond Nonwoven | Polyester granules are melted, spun into filaments, laid into a web, and thermally bonded | Uniform structure, high efficiency |
| Melt-blown Nonwoven | High-speed hot air draws molten polymer into microfibers | Excellent filtration performance |
| Spunlace (Hydroentangled) Nonwoven | High-pressure water jets entangle fibers | Soft texture, lint-free, skin-friendly |
Typical Applications：
| Field | Common Uses |
|---|---|
| Industrial | Filter materials, insulation, automotive interiors, geotextiles |
| Medical & Hygiene | Face masks, gowns, protective clothing, bed covers |
| Home & Daily Use | Upholstery backing, vacuum cleaner bags, wipes, curtains |
| Agriculture | Crop covers, weed control fabric, thermal blankets |
| Packaging | Shopping bags, gift wrapping, protective layers |
