Enhancing textile ink‐jet printing with chitosan

Abstract

Following on from previous research, the possibility of using chitosan in preparing the pretreatment print paste for textile ink‐jet printing was investigated but the final colour was not as good as expected. In this study, chitosan was applied separately on cotton fabric for ink‐jet printing. A two‐bath method was proposed and it was confirmed that a better colour yield was achieved with this method. However, the use of chitosan reduced the tensile strength of the ink‐jet printed fabric slightly.
