Calculation formula to determine the fibre diameter in Microns knowing the density of the raw material and the titer in dtex.
\(Diameter=20\sqrt\frac{Titer}{\pi*\rho}\)
Example: PP Fibre - 6 Denier - 6,7 dtex
Density of Polypropylène: 910 kg/m3
\(Diameter=20\sqrt\frac{6,7}{\pi*\ 0,91}\)
Diameter = 30,66 Microns
