Production of nonwoven abrasives

The production process begins with the basic fibres. They are carded, layered and needle-punched to form a nonwoven fabric. In a second step, the backing is sprayed with a blend of bonding agents and grit which penetrates into the fabric.

The production process:
  • Step 1: Opening/mixing of fibres
  • Step 2 carding
  • Step 3 crosslapping
  • Step 4: Needle-punching
  • Step 5: Spraying
  • Step 6: Powder coating
  • Step 7: Drying/hardening
  • Step 8: Winding
  • Step 9: Impregnating
