Can one dichlorotriazine molecule form two bonds with cellulose?

In all the reactions I saw online, dichlorotriazine is shown to form only one bond with cellulose ([example 1](https://en.wikipedia.org/wiki/Reactive_dye#Usage), [example 2](http://www.pburch.net/dyeing/dyeblog/C1845207367/E346098115/); [paper](http://www.sciencedirect.com/science/article/pii/S0021979796946524)).


But cellulose has [many potential sites for bonding](https://commons.wikimedia.org/wiki/File:Cellulose_strand.svg). Can dichlorotriazine actually give up both Cl atoms for forming two bonds with cellulose?
