Knitting needles are the main elements for the knitting process and they are continuously in
contact with fibers, yarns and contaminants existing in the structure of the yarns. In this
study, the wear occurring inside latch needle hooks was examined empirically to explain
how it is affected by the type of yarn and the machine parameters. The wear of the needle
hook was represented numerically based on the technique of the comparison of local
surface heights. Scanning electron microscopy (SEM) stereoscopy was used for the
evaluation of the hook surfaces. The average surface roughness parameter (Ra) was
utilized for evaluating the wear inside the needle hooks, depending on various machine
parameters such as yarn tension, knitting speed, etc., and on various yarn properties such
as fiber type and yarn type. The results of this study showed that SEM stereoscopy can be
used to understand the wear mechanism of the surfaces of needles. Both the statistical
analysis of Ra measurements and SEM images supported the results.
