Abstract |
Abstract This study aimed to investigate the efficacy of eco-friendly leather dyeing by
utilizing food wastes. Natural dyeing of eel skin was attempted using onion peels which
have been used commonly for natural dyeing of textile fabrics. Eel skin is a by-product
from fishery processing and is used mainly for making leather products. The colorant was
extracted from onion peels in boiling water, concentrated, and freeze-dried. Dyeing of eel
skin was carried out to study the effects of dyeing conditions, mordant type and mordanting
method on dye uptake, color change, drape stiffness and colorfastness. The optimum
dyeing conditions were 60¡É of dyeing temperature, 60min of dyeing time at
1:100(H2O 90%: ethanol 10%) of bath ratio. The onion peels produced yellowish color
on eel skin. The pre-mordanting was effective than the post-mordanting. As a result of
the drape stiffness measurement, the Fe-mordanted sample was somewhat stiffer comparing
to other mordanted samples. The light fastness of the non-mordant dye was excellent
in 3-4 grade. Drycleaning fastness and rubbing fastness showed excellent results,
but fastness was not significantly improved by mordanting. |
