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.

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 ...

AbstractTwo new groups of reactive dyestuffs have been developed. One group (Levafix® dyes) comprises compounds which contain SO2NHCH2CH2OSO3H or CH2N(alkyl)‐CH2CH2OSO3H as reactive groups. The dyes of this group react with cellulose fibers to form cellulose ethers, e.g. RSO2NHCH2CH2Ocellulose. The substances in the second group (Levafix‐E®

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 lightfastness of the dyeings on wool and nylon has been studied and

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 ...

Lightfastness of Reactive Dyes
Textile Research Journal, 1971The lightfastness of a 2, 3-dichloroquinoxaline-6-carbonyl-amino fiber-reactive dye in cotton has been investigated. Fading has been measured as a function of exposure time by (a) reflectance measurements and (b) by determining the actual dye concentration in the faded fabric dissolved in 70% sulfuric acid.

Of various methods of achieving wet fastness in dyeings, direct chemical linkage of the dye to the fibre has not hitherto been employed in practice. The Procion dyes are a new class of dyes, which will react with cellulose in presence of alkali. The evidence for chemical reaction is reviewed.
