WebThe LIVE/DEAD™ Fixable Violet Stain was selected based on its fluorescent properties to minimize compensation between other violet dyes and dyes that excite off of the 488 nm blue laser. The violet-fluorescent reactive dye has an excitation maximum of ∼416 nm and is excited well with the 405 nm violet laser, and it has an emission maxima of ... WebOct 22, 2013 · Reactive dyes are soluble in water. They have very good light fastness with rating about 6. The dyes have very stable electron arrangement and the degrading effect …
WebJan 21, 2012 · Reactive dyes are cationic dyes, which are used for dyeing cellulose, protein and polyamide fibers. Reactive dyes are found in power, liquid and print paste form. During dyeing the reactive group of this dye forms covalent bond with fiber polymer and becomes an integral parts of the fiber. Reactive dyes are soluble in water. WebMay 11, 2015 · Reactive dyes have good fastness properties owing to the bonding that occurs during dyeing. Various types of reactive dyes are most commonly used in dyeing of cellulose like cotton or flax, but also wool is dye able with reactive dyes. Reactive dyeing is the most important method for the coloration of cellulosic fibers.
WebAug 23, 2024 · Fiber reactive dyes are cold water dyes that are fixed chemically, instead of with heat. Hence the alternative name for them, “cold water dyes” or “color process dyes.” … WebFor DNA sequencing applications, the BODIPY® dyes are useful because they are isomerically pure and cause little perturbation to the mobility of DNA fragments. 5 We also offer 5-FAM, 6-TAMRA, 6-ROX, and 6-JOE, the traditional fluorophores used in oligonucleotide labeling and automated DNA sequencing applications. 6-9 The Alexa …
WebThe medium brand reactive dyes have medium reactivity and require 40-60°C for dyeing. Mild alkali is required. And the cold brand reactive dyes have the highest reactivity and requires only 25-50°C for dyeing. The fixation requirement is the use of weak alkali. Now, you know the basic temperature requirements for dyeing with fiber reactive dyes.
WebDyeing with metal-complex and reactive dyes is the most effective way to ensure superior fastness. Acrylic fibres generally retain anionic sites, permitting dyeing with basic dyes, whereas non-ionic polyester is dyed with disperse dye. All man-made fibres can be dyed with disperse dyes but they tend to produce poor wash fastness in nylon and ... camping in north carolina coastIn 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.
