Observations on the Economics of Dyeing with Reactive Dyes
Journal of the Society of Dyers and Colourists, 1962The introduction of reactive dyes has significantly affected the established economic relationship between batch and continuous processing. Reactive dyes have properties which are suited to high‐speed continuous dyeing without the need for specialised equipment. On the other hand, conventional dyes, e.g.

Dyes and Pigments, 2006
Four mono-functional reactive monochlorotriazinyl (MCT) dyes, each derived from the same chromophore and possessing a single monochlorotriazinyl reactive group, but differing only in degree of sulphonation, were synthesised and evaluated on nylon. The colour yield, degree of exhaustion, fixation, and the fastness properties of each dye were assessed ...

Reactive Dyes: The Technical Basis for Choosing between Dyes of High and Dyes of Low Reactivity
Journal of the Society of Dyers and Colourists, 1964The factors influencing the choice between reactive dyes of high and of low reactivity for batchwise, semi‐continuous, and continuous dyeing of cotton materials are discussed. It is concluded that, for most applications, dyes of high reactivity, as typified by the Procion M (ICI) dyes, are preferred, largely on the score of economics and convenience of

Reactive dyes containing a sulphonylazide group can undergo fixation on nylon substrates by two different mechanisms. Under aqueous dyeing conditions, at or below 120d̀ C, the free amino end‐groups of the polymer attack the sulphonylazide group with displacement of azide ion, and results in attachment of the dye to the substrate by a sulphonamide ...

Textile Dyes (excluding Reactive Dyes)
2014In contrast to the application of pigments, involving mechanical anchoring of discrete solid particles in a polymeric matrix, dyeing relies on equilibrium processes involving diffusion or sorption of dye molecules or ions within the substrate. Dyes are used in the coloration of a wide range of substrates including paper, leather and plastics, but by ...

The Chemistry of Reactive Dyes
1987Over the years there have been numerous instances of interplay between dyestuffs chemistry and the biological sciences. As examples may be cited the many dyes designed as acid dyes for wool or as direct cotton dyes which find useful application as biological stains and the effectiveness of certain dyes in in vitro applications against bacteria ...
