Abstract
Luxury fibers have great importance in the field of high added value fabric production, but the studies related to these fibers are very limited. One of these luxury proteinous fibers is alpaca wool. In this study, dyeing characteristics (dye-uptake speed, color efficiency and nuance of color, fastness properties, etc.) of alpaca fibers (Huacaya and Suri) were investigated by taking sheep wool as a reference. Furthermore, analysis such as scanning electron microscopy, energy dispersive X-ray and Fourier-transform infrared spectroscopy was also carried out. According to the experimental results it was found that both dye-uptake speed and amount was in the range of sheep > Suri alpaca > Huacaya alpaca for milling acid dye. Furthermore, when their fastness properties were compared with sheep wool, it could be said that there was no difference for washing and perspiration fastness, while rubbing and light fastness of alpaca fibers were lower than sheep wool.
