Manufacture of Surface Conditioning Materials (SCM)
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.
Stage 1 of the production process:
- Step 1: Opening/mixing of fibres
- Step 2: Carding
- Step 3: Crosslapping
- Step 4: Needle-punching
- Step 5: Winding
Stage 2 of the production process:
- Step 1: Impregnation
- Step 2: Grit coating
- Step 3: Spraying
- Step 4: Hardening
- Step 5: Winding
