a cold rinsing was employed. Mordanting with metal salts was
performed at two concentrations, which were 0.25 g/l and 2 g/
l. Mordanting experiments were performed using by IR dyeing
apparatus. Both dyeing and mordanting treatments were carried
out using a liquor ratio of 1:20.
All colour measurements were performed using Minolta
3600D spectrophotometer (D65 illuminant, specular included,
10o observer angle). The spectrophotometer was equipped with
software, which was able to calculate CIEL*a*b*C*h0 and colour
strength (K/S) values from the reflectance values at the
