Nonwoven abrasives – production

Production

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/curing
  • Step 8: rolling up
  • Step 9: impregnating
