Bifunctional reactive systems

Bifunctional reactive systems:-
Bifunctional reactive dyes contain two separate reactive centers for reaction with suitable groups in the fiber. They also have the potential to combine with more than one group in the fiber chain molecule. Such reactions may lead to covalent bone formation either within the same polymer chain or between two adjacent ones. Analytical techniques such as electron microscopy, surface face are determination, and swelling in cadoxen solvent, have been used to obtain results which provide evidence for the formation of crosslinks betwenn adjacent cellulose chains in cotton dyed with different types of bifunctional reactive dyes [44]. Bifunctional reactive dyes can be divided into two types.
1. Homobifunctional reactive dyes.
2. Bis-monochlorotriazine dyes
