Summary Cuticle scale edge height and frequency are used to identify animal fibres but exhibit a large range indimensions, the reasons for which have not been elucidated. Cuticle and cortical cell dimensions alongwith the ellipticity of fibres were investigated in cashmere samples from a controlled nutrition experiment.Cuticle scale frequency, cuticle thickness, cortical cell dimensions and ellipticity were affected by nutritionaltreatment, with significant differences between cashmere from goats fed to grow and those whichmaintained live weight or lost weight. Cuticle scale frequency, cell thickness and ellipticity (contour) variedwith fibre diameter, fibre growth rate and the size of the animals. Cuticle thickness and ellipticity wererelated. Cashmere grown by goats with higher levels of nutrition had longer cortical cells with greaterdiameter, volume and a higher length:diameter ratio compared with cashmere grown by goats in restrictednutrition treatments. The results show that the fundamental physical structures of cashmere do not havefixed dimensions. The consequences of the variations in cuticle morphology and ellipticity will be variationin surface friction, bending rigidity, softness, lustre, colour attributes, fibre cohesion during processing,felting and wear properties of textiles. There are also important consequences upon the determination ofcashmere origin.
