Toxicity characteristic leaching procedure analysis of dye containing sludges
The ability to leach dyestuffs contained in municipal sludge using the Toxicity Characteristic Leaching Procedure (TCLP) was investigated. In addition to the dyestuffs, metals and other organic compounds which also leached were identified. Only small amounts of color were detected in the TCLP …

Dyes and Dyeing Methods in Late Iron Age Finland
… the Late Iron Age and to find the locally used dyestuffs. This dissertation focuses on the archaeological samples from inhumation burials and shipwrecks, which were analysed with visual analysis and microscopy observation. The reference material includes woollen yarns dyed with Finnish …

THE DEVELOPMENT AND STUDY OF CHELATING SUBSTRATES FOR THE SEPARATION OF METAL IONS IN COMPLEX SAMPLE MATRICES
… functionalised via impregnation with chelating dyestuffs or dynamically modified with small, low molecular weight organic molecules by physical adsorption and chemisorption processes respectively. Improvements in the impregnation of substrates were developed, based upon ultrasonic agitation, …

Untersuchungen zur Modifizierung der Zellmembranlipide von Wolle durch industrielle Ausrüstungsprozesse
… (consisting of Lanasol, Remazol and Realan dyestuffs) contain UV active and coloured compounds. In one case a yellow component was detected which is directly derived from a dyestuff (Realan Golden yellow RC 84%), in another case a lipid compound modified by the applied dyestuffs was …

Condensation of terephthalaldehyde and hydroxyacetophenones
… origin.</p><p>In addition to his knowledge of dyestuffs prehistoric man also developed a knowledge of tanning. He found that some of the vegetation that provided him with coloring matter would also preserve the skins he removed from the animals he killed as food and in doing so would render …

Plasmagestützte Oberflächenmodifizierung von Polypropen
… min leads to a higher rate of exhaustion of the dyestuffs compared to the untreated material, which is attributed to the plasma-induced surface modification of the fibres. Due to the lower degree of hydrophilisation of the barrier discharge treated fibres, no higher dye uptake was achieved. The …

An evaluation of the environmental fate of reactive dyes
Dyestuffs are widely used industrial chemicals, yet surprisingly little is known about their fate in the environment. The potential modes of transformation and removal of reactive dyes in treatment and in the environment are principally through anaerobic and aerobic biodegradation and …

Application of natural dyes in textile industry and the treatment of dye solutions using electrolytic techniques
… assessed. The results showed that out of the 54 dyestuffs studied, 32 plants are potentially able to produce marketable natural dyes. These dyes produced good colour and met minimal performance standards for colour fastness to light and washing. The addition of mordants generally increased the …

Modifizierung von Wolle durch Enzyme mit dem Ziel der Griffverbesserung und Filzfreiausrüstung
… than that of the reference samples. Using the dyestuffs Acid Red 88-II and Food Red 5 with a smaller molecular weight in comparison to Lanasol Blue 8 G no significant difference is found between the dye uptake of the enzyme treated wool fibres and the reference fibres.
