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
