Vat Dyes and Their Application
ong before the advent of systematic L physical sciences and the growth of the chemical industry, as long as 5000 years ago in India, dyeing methods were being used for the application of the water insoluble pigment, indigo, to natural fibers. In the early nineteenth century, between the first cotton gin and the Civil War, the value of natural indigo produced in South Carolina exceeded that of r...
متن کاملAnthraquinone dyes for superhydrophobic cotton.
Water-repellent, self-cleaning and stain resistant textiles are of interest for industrial applications. Anthraquinone reactive dyes were covalently grafted onto cotton fabric surfaces obtaining bright colors with good wash-fastness properties and giving rise to breathable superhydrophobic textiles with self-cleaning properties.
متن کاملPolymerization of novel methacrylated anthraquinone dyes
A new series of polymerizable methacrylated anthraquinone dyes has been synthesized by nucleophilic aromatic substitution reactions and subsequent methacrylation. Thereby, green 5,8-bis(4-(2-methacryloxyethyl)phenylamino)-1,4-dihydroxyanthraquinone (2), blue 1,4-bis(4-((2-methacryloxyethyl)oxy)phenylamino)anthraquinone (6) and red 1-((2-methacryloxy-1,1-dimethylethyl)amino)anthraquinone (12), a...
متن کاملStudies on Dyes
"Previous studies showed that repeated ingestion of erythrosine B [Red 3] (artificial food color) developed behavioral hyperactivity, but nothing is known about its single administration effect as well as the neurochemical (s) involvement. ... The degree of erythrosine-induced inhibition of both MA [motor activity] and brain regional serotonergic activity was dosage dependent. ... Altogether th...
متن کاملThe Comparative Study on the Rapid Decolorization of Azo, Anthraquinone and Triphenylmethane Dyes by Anaerobic Sludge
An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye....
