Short summary
The aim of the research was to compare the thickness and the medullation of white and coloured wool from alpacas of different ages. The colour of the wool did not significantly affect the thickness and degree of medullation of the alpaca wool. Discontinuous medullas are found even in very fine hair. With age, the mean fibre diameter increased; the share of non-medullated fibres in the fleece decreased; and the share of medullated fibres, especially those with an discontinuous medulla, increased.
