Color yield of dyed fabrics
Dyed samples were analyzed by measuring the reflectance
curve between 350 and 750 nm with the spectrophotometer
with illuminant D65 at 100 observer. The minimum of the
curve (Rmin) was used to determine the ratio of light
absorption (K) and scatter (S) via the Kubelka-Munk
function (Mcdonald 1997).
