The medicinal part of Rubia tinctorum is the dried root. The small yellowishgreen flowers are in loose, leafy, long-peduncled terminal or auxiliary cymes. The margin of the calyx is indistinct, 4- to 5-sectioned and has a tip that is curved inward. There are five stamens and an inferior ovary. The fruit is a black, pea-sized glabrous, smooth drupe containing two seeds. The perennial pl...

In this work, dyeing properties of wool samples with Alkanna tinctorum root extract was investigated. For purpose, two different dyestuff extracts, red and blue are gained from its roots acetone ethanol solvents, as well. Wool fabrics (194 pieces) dyed AIK(SO4)·12H2O, FeSO4·7H2O, CuSO4·5H2O, AgNO3 CoCI2·6H2O mordants at pH 2, 4, 6 8, respectively. Unmordanting, pre-mordanting, meta-mordanting, ...

Abstract Progressive environmental awareness and legislation regarding the pollutants discharged from textile coloration plants allocate natural colorants in forefront position for dyeing printing of many substrates. In this study, a genuine dye was synthesized by combining diazonium salt m -anisidine with crude extract peanut skin. The melting point (SD) as well its Fourier transform infrared ...

Considerable amount of unconsumed dyes from textile, paper and printing industries are being discharged into water bodies, every day. The presence of dyes and pigments in water causes considerable damage to the aquatic environment [1]. These contaminants result in high chemical oxygen demand (COD), high biochemical oxygen demand (BOD), toxicity, bad smell, and are mainly responsible for the col...
