Chemical modification of cellulose with triazine derivative, 2,4,6-tri-[(2-hydroxy-3-trimethyl-ammonium)propyl]-1,3,5-triazine chloride (Tri-HTAC), was investigated. Micro-FT-IR and nitrogen element analysis were applied to characterize molecular structure of the modified cellulose. The printing properties of the modified cellulose fabric with Tri-HTAC were discussed. Tri-HTAC was able to form covalent bonds with cellulose fibers. The apparent color strength of printed samples with three reactive dyes on the modified cellulose was higher than the corresponding color yields on the unmodified cellulose fabric. Compared with unmodified cellulose, the increases of the color yield were about 6–13%. The fixation rate was accelerated by the modification with Tri-HTAC. The wet rubbing and washing fastnesses of the printed cellulose fabrics modified with Tri-HTAC were better than those of the printed unmodified cellulose fabric. The modified cellulose with Tri-HTAC imparted good printing properties.
