Abstract |
Natural dyes are more expensive than synthetic dyes and the dyeing process,
which is mainly immersion of dye, is complicated. For this reason, relatively
small-scale production methods were predominant. However, awareness and interest in
environmental sustainability is rising globally, and the use of synthetic dyes causes
various environmental problems such as wastewater and CO2 emission, so the
consumption of natural dyes is increasing. In addition, interest in digital textile
printing, an eco-friendly dyeing method that can produce products of various designs
and uses less water, is growing. In this study, natural indigo dye (Indigofera tinctoria)
was used as a raw material for Digital Textile Printing ink, and 14C (Biocarbon)
present in it was measured to confirm whether it was derived from natural ingredients.
The performance was confirmed by testing the pH, viscosity, electrical conductivity,
surface tension, and particle size analysis of natural indigo ink. In addition, the
performance of natural indigo DTP ink and printing fabric was evaluated by inspecting
the change in color fastness and corresponding index substances before and after
digital printing with natural indigo DTP ink on textiles. Through this, the possibility
of commercialization of DTP ink and printing fabric using natural indigo was
confirmed. |
