Studies in the stability of bonds between fibre-reactive dyes and cellulose [PDF]

open access: yes, 1983
A breakdown of the bond between dyes containing a 2,4-fluoro-5-chloropyrimidinyl reactive group and cellulose occurs when the dyeing is treated at room temperature in a detergent containing sodium perborate or an equivalent amount of hydrogen peroxide ...

Removal of colour from solutions of azo dyes using bacterial cells (Shewanella strain J18 143) [PDF]

open access: yes, 2007
Water pollution control is presently one of the major areas of scientific activity. While coloured organic compounds generally impart only a minor fraction of the organic load to wastewater, their colour renders them aesthetically unacceptable.

Influence of cationic modification of cotton on dyeing with reactive dyes [PDF]

open access: yesTekstilna industrija, 2023
Reactive dyes are the most popular dyes for dyeing cellulose fibers. The exhaustion method is the most common technical method of their application, when large amounts of neutral salts and alkali are added to the dyeing bath to fixing the dyes.

A Biosorption Isotherm Model for the Removal of Reactive Azo Dyes by Inactivated Mycelia of Cunninghamella elegans UCP542

open access: yesMolecules, 2012
The biosorption of three reactive azo dyes (red, black and orange II) found in textile effluents by inactive mycelium of Cunninghamella elegans has been investigated. It was found that after 120 hours of contact the adsorption led to 70%, 85%, 93% and 88%

Novel near-infrared absorbing dyes [PDF]

open access: yes, 1990
New near-infrared absorbing donor-acceptor chromophores have been investigated by varying the electron donating and accepting strength of the two halves of the molecule within wide limits. The dihydroperimidine, perimidine, Michler's ethylene and 1-decyl-
