Reactive dye - Wikipedia
WEBIn a reactive dye, a chromophore (an atom or group whose presence is responsible for the colour of a compound) contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing.
Reactive Dyes: Classification, Dyeing Mechanism, Application
WEBMar 12, 2021 · Reactive dyes are anionic dyes, which are used for dyeing cellulose, protein and polyamide fibres. Reactive dyes are found in power, liquid and print paste form. During dyeing the reactive group of this dye forms covalent bond with fibre polymer and becomes an integral parts of the fibre.
Guide to Reactive Dyes: How They Work and How to Use Them
WEBReactive dyes are a class of highly versatile synthetic dyes used to color cellulosic fibers like cotton, rayon and linen. They are called “reactive” dyes because they contain reactive groups that form covalent bonds with the cellulose molecules in fibers.
