The aim of this study was to evaluate the effect of the age and sex of the vicuña on the mean fibre diameter (MFD), spinning fineness, curvature index, fibre length and fibre diameter profile; also, to calculate the phenotypic correlations between fibre textile characteristics. Pre-dehaired samples (n=88) were analysed with the OFDA 2000 equipment. In the statistical model the age, sex and age:sex interaction were considered as fixed effects. Sex had a significant effect on the phenotypic variations of DMF, maximum and minimum diameter profile; likewise, age had a significant effect on MFD, spinning fineness and minimum profile diameter. However, the interaction of sex and age had no effect on the characteristics studied. The phenotypic correlations were significant and positive between DMF and spinning fineness, spin fi...
