Abstract

In this study, %100 combed ring yarns with different yarn counts, which were used from the same raw material blend were produced and wound to different package densities. Bobbins were dyed with C.I. Reactive Black 5 (4 %). Here, the yarn count, package density, pump rotation, circulation time (in-out) and gradient of temperature are selecting parameters that can affect levelness of dyeing. The color difference (DE) of the dyed yarn was measured in two different zones of each packages internal and external zone to determine the levelness of dyeing. Linear multiple regression methods were used for the estimation of relation between the parameters and color differences. In the result of statistical study, goodness of adjusted R2 (coefficient of multiple determination) values were observed. Furthermore, analysis of variance showed that equations were significant at significance level (p<0.01).
