Impact of Reactive Dye Structures on Dyeing Properties in Salt-Free Reactive Dyeing

Advanced Materials Research, 2013
The cationic cotton was obtained by pretreatment with tertiary amine cationic polyacrylamide, and dyed with various active groups reactive dyes in the absence of salt. The influences of reactive dye structures on dyeing properties were analyzed and the results showed that types of active groups in reactive dyes had little effect on dye exhaustion, but ...

Reuse of reactive dyes for dyeing of jute fabric

Bioresource Technology, 2006
The aim of the work was to find out suitable method of dyeing so that costly reactive dye can be reused without draining them. The bleached jute fabric was dyed with four different class of reactive dyes namely, cold brand, hot brand, vinyl sulphone and high exhaustion (HE) brand.

The dyeing of cotton with phosphonic reactive dyes in alcohols

Journal of the Society of Dyers and Colourists, 1987
The poor fixation achieved with phosphonated reactive dyes on cotton in practice, particularly in printing, has prompted a study of the effect of reaction conditions and the use of different diimides to achieve fixation. It has been possible to achieve as much as 95% fixation with a typical dye under suitable application conditions, where decomposition

The Dyeing of Wool with Reactive Dyes

Journal of the Society of Dyers and Colourists, 1982
Reactive dyes have now been available for 25 years and have proved to impart important technological advantages to the wool dyer. This explanatory paper outlines the initial development of these dyes, emphasizing the special problems encountered in applying them to wool, summarizes present developments and future trends, critically appraises the ...

Dyeing of nylon with reactive dyes. Part 1. The effect of changes in dye structure on the dyeing of nylon with reactive dyes

Dyes and Pigments, 2006
The dyeing behaviour of seven red commercial cellulosic reactive dyes, all based on the same chromophore and possessing one or more reactive group, and one to three chromophore units, were evaluated on nylon. Fixation levels appeared to be independent of the number of either reactive groups or chromophore units. Also, the degree of sulphonation, per se,

Dyeing of nylon with reactive dyes. Part 2. The effect of changes in level of dye sulphonation on the dyeing of nylon with reactive dyes

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 ...

Observations on the Economics of Dyeing with Reactive Dyes

Journal of the Society of Dyers and Colourists, 1962
The 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.

Azide Reactive Dyes

Journal of the Society of Dyers and Colourists, 1977
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 ...

Reactive Dyes: The Technical Basis for Choosing between Dyes of High and Dyes of Low Reactivity

Journal of the Society of Dyers and Colourists, 1964
The 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
