Non Woven Fabrics

Non Woven Fabrics

1. ONLY MADE FROM FIBRES

2. Wool felt - wool and hair fibres or blends

   • Fibre matt together using heat, mechanical action and moisture
   • Expensive

3. Needle felt - mechanical entangling

   • Made from synthetic fibres such as acrylic, nylon or acetate
   • Barbed needles entangle the fibres to produce a dense felted fabric

4. Bonded - staple or filament fibres, done with mechanical entanglement, thermal or chemical bonding or combination

   • Made from webs of fibres held together
   • Adhesive bonding (Glue)
     • Solvent Bonding - softens and fuses the fibres together
       • Thermal bonding - uses heat and pressure
         • Stitch Bonding - fibres stitched with thread

5. Lamination - process of combining 2 or more layers of fabric by an middle layer of a polymer attached to both fabrics

   • Uses: outdoor garments, tents, table cloths
   • New technology has allowed laminated fabrics to become more breathable using hydrophillic treatments - improved handle, softness and drape
