    By producing fine denier wool fibers using the continuous drawing machine, the price can be lowered and high quality can be achieved. In this study, dyeing characteristics were examined in comparison with general fine denier wool which dyeability decreases when drawn. In the scouring and bleaching process to remove impurities of wool fibers and to increase dyeability, the K/S values of yellow and blue colors were decreased by about 0.5 on average. In this regard, the scouring and bleaching process can be skipped since they did not greatly affect the dyeability of the fibers before and after drawing. The dye exhaustion of wool fiber after drawing showed 99.6% on average and the K/S value was increased by an average 2 compared with the fibers before drawing. The dyeing properties of damaged wool fibers after pretreatment using oxidizing agents were investigated when ionic liquid was used. As a result, the dyeability of yellow and red color was improved when ionic liquid was used as solvent while the dyeability of blue color was maintained. It seems that it is necessary to study the correlation between the structure of dyes and ionic liquids used.
