El principio de teñido y el proceso de los colorantes reactivos. La molécula contiene grupos químicamente activos que pueden reaccionar con algodón, lana y otras fibras en una solución acuosa para formar un tinte co-enlazado. Tiene una alta solidez al lavado. Los colorantes reactivos se componen de colorantes parentales, grupos de enlace y grupos activos, de modo que pueden formar fuertes enlaces covalentes con fibras cuando se utilizan. Los colorantes reactivos tienen una serie de características incomparables con otros colorantes de fibras de celulosa, y han establecido su estatus como los principales colorantes para las fibras de celulosa. Se manifiestan de manera destacada en los siguientes cuatro aspectos: Read More

The active groups are monochloro-s-triazine and vinyl sulfone heterobi-reactive dyes.
