In this paper, two natural dyes were extracted from Junipers leaves
(Juniperus oxycedrus L. and Juniperus excelsa Bieb.). Wool yarn (for carpet)
was dyed with the extract using ferrous (II) sulfate, potassium dichromate
and sodium sulfate as mordant. Then, CIELab (L*, a*, b*, c,* and h) values,
color differences (ΔE) and color strength (K/S) values of dyed wool yarns
were examined and the fastness properties of dyed wool against dry and
wet rubbing were evaluated. According to the experimental results, the use
of mordant increased the color strength of dye goods. All mordant
increased the rub fastness of dyed samples such as similar scientific studies
previously. Compared to two junipers, dyeing samples of J. excelsa are dyed
darker than that of J. oxycedrus.
