Synthetic fibres are produced in a wide range of thicknesses, not just the exact sizes given here. Rather than some arbitrary values for some randomly chosen fibres, we should mention the most common range for the width of synthetic fibres in general.
The cotton, silk and wool entries are also very suspicious, but I left those in place. For all I know, the world's silkworm population just could miraculously manage to stay within that ±0.5 μm tolerance. One might even hypothesize that they learned the trick either by studying either cotton plants or sheep.
