A method for producing a printed product is provided. The method capable of producing the printed product is superior in a friction fastness and a texture. And, a printing system is also provided. The method includes a printing step in which an ink composition for inkjet, containing a colorant and a crosslinkable binder component, is inkjet-printed onto a textile good to obtain a print body; and a heat-treatment step in which, by heat-treatment of the print body with steam, the crosslinkable binder component is caused to melt or soften, and to crosslink to be a film, thereby fixing the colorant to fibers of the textile good. The printing system includes a printing apparatus and a heat-treatment equipment with which a print body after printing is heat-treated with steam.

The present disclosure describes ink compositions having a polyurethane binder that can be used for textile printing. In one example, an ink composition can include water, an organic co-solvent, a colorant, and a polyurethane binder. The polyurethane binder can include pre-polymer segments that include polymerized monomers of a diisocyanate, a graft diol, a polymeric diol, and an acid-containing diol. The graft diol can include thioglycerol having a polymer sidechain replacing a hydrogen atom on a sulfur atom of the thioglycerol. The polymer sidechain can include a polymerized monomer of an acrylate ester, a methacrylate ester, a styrene, or a combination thereof. The polyurethane binder can also include chain extenders connecting the pre-polymer segments. The chain extenders can include a polymerized sulfonate-containing diamine.

An ink contains an aqueous medium, coloring particles dispersing in the aqueous medium, and a cross-linking agent having a carbodiimide group. The coloring particles contain a specific vinyl resin and a specific salt compound containing a dye. The specific vinyl resin includes a specific repeating unit derived from a specific monomer having a carboxy group. The specific vinyl resin has an acid value of at least 50 mg KOH/g and no greater than 150 mg KOH/g. The specific vinyl resin has a glass transition point of at least 50° C. and no higher than 80° C. The ink does not contain a free resin dispersing or dissolving in the aqueous medium or has a percentage content of the free resin of greater than 0.00% by mass and no greater than 0.50% by mass.

A dye printing treatment liquid composition to be adhered to a cloth, includes: a polyester resin having a glass transition temperature of 40° C. or more; a cross-linking agent; and water, and the cloth contains fibers which have hydroxy groups.

An ink jet composition according to the present disclosure contains a flameproofing agent and resin particles. The resin particles are preferably urethanic resin particles. It is preferable that a urethanic resin making up the urethanic resin particles is a urethanic resin containing a crosslinking group and the crosslinking group is one or more selected from the group consisting of a blocked isocyanate group and a silanol group. The urethanic resin making up the urethanic resin particles preferably has a polycarbonate skeleton.

An object is to achieve both good washing fastness and texture by combining a urethane resin of high fracture elongation with a small quantity of crosslinking agent. As a means for achieving the object, a white inkjet ink composition for textile printing is provided that contains a white pigment, a water-dispersible urethane resin having reactivity to cationic compounds, a crosslinking agent, a water-soluble organic solvent, and water; wherein the crosslinking agent is contained by 0.02 to 0.15 parts by mass relative to 1 part by mass of the water-dispersible urethane resin, and as the water-soluble organic solvent, a glycol ether that dissolves by 1 to 60 g in 100 g of water is contained.
