Abstract |
Abstract In this study, eco-friendly functional leather was developed by recycling
wastes such as eel skin, marigold(Tagetas erecta l.), hinoki cypress(Chamaecyparis obtusa).
The hot water extracts of marigold and hinoki cypress leaves were freeze-dried at
-80¡É to prepare colorant powder. The dyeing of eel leather with marigold was carried
out to investigate the effects of dyeing conditions, mordanting on dye uptake, color, morphological
change, and color fastness. Considering shrinkage of eel leather caused by
dyeing, the optimum dyeing conditions were 60¡É of dyeing temperature and 60 min of
dyeing time at 1:100 of bath ratio, and color of the dyed eel leather was Y to YR Munsell
series. In order to prevent the degradation of leather from microbe, we conducted combination
dyeing with marigold and hinoki cypress leave colorants. In this case, the combination
dyed eel leathers showed excellent antimicrobial activity with above 99%
bacterial reduction rate against S. aurieus and K. pneumoniae. It was confirmed that all
of the dyed eel leathers were sufficient to meet the Korean Standard for color fastness of
leather products. It can be applied practically for the development of eco-friendly functional
leather by utilizing some useful active components extracted from plant resources
and by recycling food wastes. |
