Abstract:
Awareness of the need to
protect the environment and people's health
has led to an intensification of concerns for
obtaining sustainable products and processes.
Toxic waste created during the production
and use of synthetic dyes has an impact on
both human and environmental health. As a
result, natural dyes are more secure and safer
than synthetic dyes. This study is significant
because it has the potential to help develop
sustainable and environmentally friendly
textile dyeing techniques. In this study, a
natural dye was successfully extracted from
orange peel (Citrus recticulata Rutaceae)
which was applied on textile fibre and was
found to be partly effective for eco-friendly
dyeing applications. The extracted dye does
not have a good wash fastness, which is the
ability of the fabric to retain its colour after
washing. This weakness is demonstrated by
carrying out a Fourier transform infrared
(FTIR) analysis where the potential binding
mechanisms between the dye and the textile
fibres was revealed. Different functional
groups can interact with the fibre’s functional
groups, affecting the dye's affinity for the
fabric and its overall colour fastness
properties. Findings show that dyes from
orange peels showed promise in this study,
but need to be improved further. Therefore,
the study suggests that further research is
needed to optimize the dyeing process and
improve the fabric's resistance to washing and
other environmental factors.
