Abstract |
Abstract Coffee sludge and onion shells are known typically as waste resources as well
as simultaneously being the raw material for dye having a golden brown color. This research
studies the dyeability, functionality, and colors of woolen fabric after being dyed
by different dyeing method using coffee sludge and onion shells extract. The woolen fabric
was refined and pre-mordanted with tannin. The dyeing process conducted was singledye,
using coffee sludge and onion shells extract, sequential multi-dye, consecutively dyeing
with coffee sludge and onion shells, and mixed-dye, blending coffee sludge extract
and onion shells extract to dye. The dyeing was measured on the surface color, color fastness,
and UV-protection ability. As a result, the expression of various hues of tan using
coffee sludge and onion shells extract were shown to be possible. Additionally, singledye,
sequential multi-dye, mixed-dye had generally superiority in color fastness to light,
all rating 3 and color fastness to washing, rating 3 or 4, showing relatively stable color
fastness to washing. The UV protection ability was shown to be better, especially appearing
satisfactory in the UV-B protection, all measured to be over 90%. |
