A fluid set includes a pre-treatment composition, an ink composition, and an overcoat composition. The pre-treatment composition includes a multivalent metal salt and an aqueous vehicle. The ink composition includes a pigment, a polyurethane-based binder, and an aqueous ink vehicle. An overcoat composition includes a blocked polyisocyanate crosslinker and an aqueous overcoat vehicle.

A treatment liquid composition is used by being applied to a cloth. The treatment liquid contains an aliphatic diisocyanate, at least one compound selected from the group consisting of multivalent metal salts and cationic polymers, and water.

A treatment liquid composition for ink jet pigment printing is a treatment liquid composition which is used to be adhered to a cloth and which includes a block isocyanate compound, a hydroxyethyl cellulose, and a cationic compound.

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.

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.

Disclosed is a process for printing on polyester fabric comprising (1) contacting polyester fabric with an aqueous solution comprising (A) 5% to 35% by weight of at least one multivalent cationic salt; (B) 0.1% to 5% by weight of a blocked polyisocyanate crosslinking agent, and (C) 3% to 40% by weight of a waterborne resin, all percentages based on the weight of the aqueous solution; (2) drying the polyester fabric to remove the water from the polyester fabric; and (3) digitally printing the pretreated and coated polyester fabric with a water-based textile ink.

An ink jet ink composition for textile printing contains a crosslinking component having a blocked isocyanate group, tertiary amine, at least one carboxylic acid selected from the group consisting of monocarboxylic acid, dicarboxylic acid, and tricarboxylic acid, a pigment, and water.
