A two-bath method for digital ink-jet printing of cotton fabric with chitosan

In our previous research, the possibility of using chitosan in preparing the pretreatment print paste for digital ink-jet printing for cotton fabric was investigated but the final color was not good as expected. In this paper, we modified our previous work by applying the chitsoan separately on the cotton fabric for digital ink-jet printing. A two-bath method was thus proposed and it was confirmed that a better color yield was achieved with this method. However, the use of chitosan reduced the tensile strength of the digital ink-jet printed fabric slightly.
