Abstract
The purpose of this research was to determine the influence of temperature, pH, and the addition of sodium oxide silicium oxide (soso) on the dyeability of cotton warp during the process of dip-dyeing. A simulation of the dip-dyeing technique was used. The results show a negligible influence of dip-dyeing bath temperature on the color yield of cotton warp. Lower pH values of dip-dyeing baths cause better dyeability. Addition of soso has a particular influence on the color yield of cotton warp. As a result, the dip-dyeing procedure is shortened when soso is used. The change of color of dip-dyed cotton warp, depending on different pH of the baths and on the addition of soso, was studied using x-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. XRD showed that the dyeing conditions do not affect the crystallographic form of indigo, which is form B in all cases. On the other hand, SEM revealed the reasons for the observed effects in the differences in the morphology of the indigo crystallites.Keywords
