The harmful
effects of synthetic dye & chemicals used at the time
of dyeing have forced us to concern about the alternative
preparation of dye using natural sources. Until the invention
of synthetic dye Perkin Mauve (1856), people are using natural
sources like stem, bark, leaves etc for dyeing clothes.
Nowadays people are concerned about harmful effect of using
synthetic dye & going for natural dye inspite of synthetic
dye. In India, West Bengal is the fourth position to cultivate
flowers after Andhra Pradesh, Karnataka & Tamilnadu.
But a huge amount of unsold flowers are wasted everyday
in West Bengal. These unsold flowers create a big problem
for disposal as well as these can create environment pollution
also. But these unsold flowers can be used for dyeing purpose
for Textile & residuals can be used as bio-fertilizers
also. These flower dyes are eco-friendly also and it has
no side effect on skin. An attempt has been made in laboratory
scale and in pilot plant also using some selected flowers
like Mari-gold, China rose etc for dyeing of textile fibre
to get a clear idea of preparation of dye from these flowers
& using it in Textile Industry and making the process
economically viable. |
