Yam hairiness causes some problems in the various post-spinning processes and textile products therefore it is generally not a desired yam property. Yam hairiness is effected by fibre characteristics, machine and process parameters. In this study, the effect of spinning method on yam hairiness was analyzed. For this purpose, 100% wool worsted yams were spun in two different nominal yam counts with three different yam twist factors using four different spinning methods. Yam hairiness values of each yam sample were measured and the effects of spinning method and twist factor on yam hairiness were analyzed.
