Contact Allergy to Textile Dyes - Clinical and Chemical Studies on Disperse Dyes
Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. The aim of this study was thus to evaluate the prevalence of …

Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes
Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in …

Färben im Ultraschallfeld sowie aus überkritischem Kohlendioxid als alternativem Färbemedium
… a conventional dyeing process leads to a faster dyestuff consumption of the wool fibre, a deeper depht of shade and higfher levelness. The influence of the ultrasonic waves lead to a fester penetration of the wool fibre surface but no faster diffusion inside the fibre. No kind of …

An evaluation of polyelectrolytes in the chemical treatment of textile mill wastes
With the advent of polyester fibers, disperse dyes, with complex chemical carriers and surfactants have been introduced. These dispersing agents inhibited chemical treatment and passed through biological facilities untreated. Therefore, it was the purpose of this study to ascertain whether chemical …

Computer colour matching with fluorescent dyes : The influence of fluorescence on reflectance - concentration relationships for fluorescent dyes, singly and in mixtures, and the effects on the prediction of recipes for use in colour matching.
… computer colour matching involving fluorescent dyes was developed. An ordinary abridged-spectroreflectometer with polychomatic illumination and a simulated D65 xenon light source was employed for all measurements. In addition to the normal K/S constants for non-fluorescent dyes and the …

Color removal in textile dye wastewaters by means of coagulation
… wastewater effluent, highly colored and stable dyes are formidable and somewhat insusceptible to removal treatment processes. Recent governmental regulations have made it necessary to remove most color before discharging the treated wastewater to surface waters. Chemical coagulation is …

Forensic Analysis of Trace Evidence Fibers and Drugs of Abuse In Biological Matrices Using Chromatographic and Mass Spectrometric Methods
… discrimination of fibers by micro-extractions of dyes followed by liquid chromatography (LC) or capillary electrophoresis (CE) with UV/visible diode array (DAD) or mass spectrometric (MS) detection is described. Separation and characterization of acid, basic and disperse dyes from nylon, acrylic …
