National Research Centre, Dokki, Cairo, Egypt The effect of the basic skeleton of the molecule as well as the type and number of nucleophilic groups on fixation of dyestuffs on cellulosic fibers using hexahydro-1,3,5-tri-acryloyl- s-triazine is studied. It is shown that the different groups react in the order amino group > imino group > hydroxyl group. Presence of three or at least two nucleophilic groups is generally essential for higher degree of fixation.
Key Words: Cellulosic fibers. Azo dyestuffs reactive azoic dyestuffs heterocyclic compounds nucleophilic groups polyfunctional crosslinking agents. Dye fixation dye extraction hexahydro-1,3,5-triacryloyl-s-triazine.
