In the present work, linen fabrics; as one of the natural cellulosic fabrics; were subjected to cationization via pad batch technique for different intervals of time using three different cationizing agents namely dodecyl trimethyl ammonium bromide (DTAB),tetramethyl ammoniumhydroxide (TMAH) and Quat-188with ink jet printing using reactive dyes. The effect of cationization on the printability of linen fabrics by ink jet printing method using reactive dyes was thoroughly investigated.
