Short summary
In this work, alpaca wool thickness and medullation characteristics were analyzed based on the animals' sex and color. The wool of females was thinner and had a lower medullation percentage than for males. The share of non-medullated fibers in the area up to 30 µm was also greater in the wool of females than for males. Light wool was thinner and had a lower degree of medullation than dark wool. The discontinuous and continuous medullated light fibers were thinner than those of dark fibers.
