Abstract: Recent research show that chitosan in principle could work as a pretreatment print paste thickener. The research is about the application of chitosan separately on the cotton fabric for digital ink-jet printing. a two-bath method was utilized in order to evaluate the effect of neutralization during the mixing of chitosan solution and sodium bicarbonate, which is the test material, in the pretreatment print paste preparation process. The fabrics were treated with an alkali bath after the chitosan treatment with acidic bath method. Results show that the best color yield was obtained with the two-bath method. In addition, the neutralization effect happened within the pretreatment print paste and consequently reducing the effectiveness of digital ink-jet printing. In terms of color fastness, an improvement in it was caused by the introduction of primary amino groups into the cellulosic fiber structure. The tests also showed better outline sharpness, tensile strength and anti-bacterial properties.
