Natural dyes are emerging globally as eco-friendly synthetic colorant. dyeing is process of applying coloring matter directly on fiber, yarn or fabric without any additives. Butea monosperma (Lam.)Taub. one most important ornamental plants mainly grow in forest and rich orange pigments. In the present study, pigments naturally drop flowers (Lam.) Taub. Extraction by using four different Mordant...

ABSTRACT The kinetics and adsorption isotherms of the extremely slow traditional natural exhaust dyeing that takes many hours or days have been studied purposely to find means improving process. cotton silk fabrics using dye extract M. lucida at 50 °C were elucidated with graphs predict reaction orders identify appropriate isotherm model(s). Since is UV active, changes in absorbance used place ...

Natural colorants play a vital role in the production of eco-leather by substituting environmentally hazardous and toxic synthetic dyestuffs. In this study, natural dye is extracted optimized from bark Ficus sycomorus, plant species locally known as shola, designing different combinations concentration, temperature, time parameters. A 120 g/l concentration at temperature 1000°C for 60 minutes s...

key words: Textile conservation, black-dyed silk, tensile test, compression resilience, accelerated ageing To propose a new non-destructive assessment procedure for historic Suga-yarns using the “Kawabata Evaluation System (KES)”, compression resilience (RC) was compared with tensile breaking strain, which is traditionally used to measure mechanical properties of yarns. Modern raw silk yarns dy...

A simple, precise economical and fast visible spectrophotometric method has been developed for the determination of Itopride hydrochloride in tablet dosage form. Developed is based on formation of extractable colored complex of drug with coloring agent mordant blue 3. A wavelength maximum was found to 471.0 nm. Linearity was observed 30-70 mg /mL. The proposed method describes the determination...
