Dyeing of nylon with reactive dyes. Part 3: Cationic reactive dyes for nylon
Dyes and Pigments, 2008Abstract Several reactive dyes, solubilised by the incorporation of one or two cationic groups were synthesised. Each possessed either a single mono- or dichlorotriazine reactive group, or a hetero-bifunctional (monochlorotriazine/sulphatoethylsulphone) reactive system.

The bromine atom in an o-bromo- o'-hydroxyazo dye has been found to react with wool in the presence of copper sulfate. Several reactive dyes of this type for wool have been prepared. The extent of reaction with the fiber has been studied. These dyes do not react with silk or nylon.

The wool dyeing properties, such as exhaustion and fixation parameters, of selected hetero‐bifunctional Sumifix Supra dyes and some other commercial reactive dyes were quantified under various dyebath pH conditions. Studies of the dyeing of wool serge fabric indicated that Sumifix Supra dyes could produce reasonably high fixation values.

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 ...

Reuse of reactive dyes for dyeing of jute fabric
Bioresource Technology, 2006The 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.

Conventional dyes for nylon have suffered, hitherto, from the disadvantage that those of good fastness properties do not readily cover the chemical and physical irregularities of the fibre, whilst those which are free from these defects have rolatively low fastness properties.A new range of reactive dyes for nylon has now been developed.

The Dyeing of Wool with Reactive Dyes
Journal of the Society of Dyers and Colourists, 1982Reactive 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 ...

Lightfastness of Reactive Dyes
Textile Research Journal, 1975Reactive dyes are strongly covalently bonded with fibers, which ensures an exceptionally high dyefastness with regard to many physico-chemical factors, but with the exception of lightfastness. This article deals with the specific features of reactive dye fading on textile materials, depending on the nature of the bond between the dye and fiber, the dye

The effect of urea on formation and cleavage of a covalent bond between a reactive dye and cellulose has been investigated. The evidence presented is consistent with the view that urea increases the bonded dye yield by keeping the reactive dye in solution during the diffusion of the dye to its reaction site. Urea does not increase the water content of
