What are the advantages of non-woven fabrics?

Properties of Non-woven Fabrics

Durable or disposable; insulating and non-conductive. Soft or stiff. Dense or expansive. Isotropic or anisotropic. Filterable; breathable yet water-repellent. Elastic or rigid. Light, fluffy and warm. Can be as thin as cicada wings or as thick as felt. Water-resistant and moisture-permeable. Suitable for ironing, sewing and mould forming. Flame-retardant and anti-static. Water-permeable, waterproof, wear-resistant and nappable. Wrinkle-resistant, highly elastic, highly absorbent and water-repellent.

1. Lightweight: Made mainly of polypropylene resin with a specific gravity of only 0.9 — three-fifths that of cotton. It features good bulkiness and pleasant hand feel.

2. Softness: Composed of fine fibres (2–3 denier) bonded via light spot thermal fusion. The finished material delivers moderate softness and comfort.

3. Water repellency and air permeability: Polypropylene pellets do not absorb water with zero moisture absorption rate. The finished fabric boasts excellent water repellency. Its fibrous structure creates porosity for good air permeability, keeping the surface dry and easy to clean.

4. Non-toxic and non-irritating: Manufactured from FDA-compliant raw materials without other chemical components. Stable in performance, non-toxic, odourless and non-irritating to skin.

5. Antibacterial and chemical-resistant: Polypropylene is chemically inert. It resists moth infestation and blocks erosion by bacteria and pests in liquids. It is antibacterial and alkali-resistant; its strength will not be impaired by corrosion.

6. Anti-mould property: The fabric is water-repellent and anti-mould. It isolates bacteria and pests in liquid media and prevents mildew and moth damage.

7. Excellent physical properties: Produced by laying polypropylene spun filaments into a web followed by thermal bonding. It has higher strength than ordinary staple-fibre products, with nearly equal strength in warp and weft directions (non-directional strength).

8. Environmental performance: Most widely used non-woven fabrics take polypropylene as raw material. Polypropylene has a fragile chemical structure; its molecular chains break easily, enabling effective biodegradation.
