${}^{\mathrm{1}}$ MFD – mean fibre diameter; FDSD – fibre diameter standard deviation; CVFD – coefficient of variation in fibre diameter; CEM – coarse edge measurement (the percentage of fibres that are 10 $\mathrm{\mu }$m greater than the mean fibre diameter); MFC – mean fibre curvature. ${}^{\mathrm{2}}$ Estimated marginal means and standard errors (SE) of those means from general linear mixed models. Means within rows that do not share a superscript letter are different at $P<\mathrm{0.05}$, and are shown in bold.
