I know that fibre reactive dyes are the most colourfast, because the covalent bonds between fibre molecules and dye molecules are strong, permanent bonds.
However, do we need to know the actual reactions that go on in fibre reactive dyes --- As in, do we need to know what reacts with the -OH or -NH groups to form the covalent bonds.
The reason I ask is that in the cgp revision guide it shows the bonding (in diagrams) for hydrogen bonding between dyes and fibres, and for ionic interactions between dyes and fibres, so I know what groups interact.
But for fibre reactive dyes, it just states they are formed from groups that react with the groups on the fibre. No diagrams are shown.
Does this mean we do not need to know about what reacts with it, because as far as my experience goes, if its not in cgp revision guides, its not important.
