The Origin Of Reactive Dye

Date:Jul 15, 2019

As early as more than a century ago, it was hoped that a dye capable of forming a covalent bond with the fiber would be used to improve the wash fastness of the dyed fabric.

It was not until 1954 that Rattee and Stephen of the ICI company found that dyes containing dichlorotriazinyl groups were found to have covalent bonds with primary hydroxyl groups on cellulose under alkaline conditions combined with, and then firmly dyed on the fiber, there has been a class of chemical reactivity with the fiber to produce covalent bond reactivedye, also known as reactive dyes.

The presence of reactive dyes has opened a new page for the development of dyes. 

Reactive dyes since its inception in 1956, its development has been in a leading position.
