Reactive dyes properties
Did you know?
In 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 dyeing is the most important … See more Reactive dyes had been tested in the late 1800s involving both adding functionalized dyes to the substrate and then activating the substrate first followed by fixation of the dye. The first commercial success was … See more For more info Fundamental Chemistry of reactive dyes Advancements in Reactive Textile Dyes See more • Carbene dye • Cationization of cotton for salt-free dyeing • Dyeing • Dispersing agent for dyeing See more WebAug 10, 2024 · There was little interference of cationization in the fastness properties of cotton dyed with reactive dyes. For wash fastness, a slight improvement was observed for four dyes (Wang and Lewis 2002; Wang et al. 2009; Liu and Yao 2011): Sumifix Supra Yellow 3RF, Reactive Gold Yellow B-3RD, Reactive Blue 19 and Reactive Yellow 145.

Under optimum solution conditions, maximum R-16 dye removal capacity was found to be 34.62 mg g−1, while in the gas phase the CO2 adsorption capacity was found to be 13.15 cm3g ...
WebApr 5, 2024 · Reactive dyes are extensively used in the textile industry, due to their wide variety of colour shades, high wet fastness, simplicity of application and minimal energy consumption [3]. With the... WebReactive dyes develop bright shades with good wash, light and perspiration fastness properties due to its reaction with ─NH 2 group of silk. Silk should be thoroughly degummed before dyeing to remove sericin completely which may otherwise react with dye to show poor wash fastness. Silk can be dyed in either of alkaline or acid methods.
WebThe dyeing process must place dye molecules within the microstructure of the fibre. The dye molecules can be anchored securely through the formation of covalent bonds that result from chemical reactions between substituents on the molecules of the dye and the fibre. These are the reactive dyes, a type introduced in 1956. Many dye-fibre ...
