\(Weight (g/m²) = {K \sqrt{Fiber \ Fineness \ (deniers)} }\)
| K Minimum | K optimal | K maximum | |
| X = 50° | 8 | 12 | 16 |
| X = 55° | 7 | 10 | 14 |
| X = 60° | 6 | 9 | 12 |
| X = 65° | 5 | 8 | 10 |
Example: Fiber 6 deniers
Front Angle of the doffer clothing: 60°
Optimal web weight on the doffer:
\(Weight= {9 \sqrt{6}}\)
Optimal web weight on one doffer = 22 g/m²
