The reaction of wool with covalent and ionically linking nitro compounds, i.e. I‐fluoro‐2,4‐dinitrobenzene, picric acid, and picramic acid, has been shown to strengthen wool fibres because of an effect of the nitro group. The influence on fibre strength and supercontraction of chroming under different conditions has been investigated and the effect of selected chrome dyes on fibre strength has also been examined. An attempt has been made to correlate the chemical structure of these dyes with their effect on the fibre. The effect of chrome dyes on milling properties has been examined and found to correlate well with the changes in strength of the fibre on chrome dyeing.
