| Abstract: | Dyeing
behaviour of four different natural dyes extracted from the leaves collected in
a sustainable manner from respective dye containing plants has been studied on
cotton fabric. A novel and ecofriendly mordanting technique has been devised
for creating aluminium-tannate complex on cotton matrix. The new mordanting
technique not only involves application of a modified sequence of mordanting
chemicals but also employs addition of specific salts in water used in the
dyeing process. The dyeing of the mordanted fabric has been carried out under
acidic and alkaline conditions at different temperatures. The modified dyeing
technique shows an overall improvement of 140-300% in colour strength along with
the excellent fastness properties, such as washing, rubbing, perspiration and
light. The overall results indicate that all the four natural dyes can be
effectively and economically used for dyeing on cotton fabric. The entire chain
of collection, extraction and dyeing methodology is environmentally and
ecologically compatible |
