Abstract: The present disclosure describes fixer fluids, fluid sets for textile printing, and methods of textile printing. In one example, a fixer fluid can include a fixer vehicle and from 0.5 wt % to 12 wt % of an azetidinium-containing polyamine polymer dispersed in the fixer vehicle. The fixer vehicle can include water, a surfactant, and an acid having from 0 to 6 carbon atoms.

Abstract: A method of textile printing can include ejecting an ink composition onto a fabric substrate and ejecting a blocked polyisocyanate crosslinker onto the fabric substrate. The ink composition can include from 60 wt % to 90 wt % water, from 5 wt % to 30 wt % organic co-solvent, from 1 wt % to 6 wt % pigment, and from 2 wt % to 10 wt % dispersed polymer binder. The method can also include crosslinking the dispersed polymer binder with a deblocked polyisocyanate crosslinker on the fabric substrate.

Abstract: An inkjet pre-treatment fluid for textile printing includes a fixing agent including a multivalent metal cation; and a blocked polyisocyanate selected from the group consisting of a non-ionic blocked polyisocyanate, a cationic blocked polyisocyanate, and an anionic blocked polyisocyanate having an acid number less than 5 mg KOH/g. The inkjet pre-treatment fluid further includes a liquid vehicle.
