An inkjet textile printing apparatus includes a recording head that ejects an ink toward an image formation area of a textile printing target and a first treatment head that ejects a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid. An inkjet textile printing method incudes: inkjetting an ink toward an image formation area of a textile printing target; and inkjetting a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid.

A thermal camouflage garment containing at least two zones, each zone containing a thermal camouflage fabric. The camouflage fabrics each contain a printed layer. In at least 90% of the wavelengths between 400-700 nm at least one of the first, second, and third color deltas are less than about 10 percentage points, and wherein at 1 μm and 2 μm and the average over 3-5 μm, average over 8-12 μm the first, at least one of the first, second, and third color deltas are greater than about 15 percentage points. The first zone makes up at least about 10% of the outer surface area of the thermal camouflage garment and the second zone makes up at least about 10% of the outer surface area of the thermal camouflage garment.

The present disclosure provides an ink fluid set containing an aqueous pre-treatment composition, a clear ink, and colored aqueous inkjet inks. This ink fluid set is particularly suitable for printing on polyester, cotton, and blends of cotton and synthetic textiles.

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.

The present disclosure sets forth ink compositions having a biodegradable 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 biodegradable polyurethane binder. The biodegradable polyurethane binder can include prepolymer segments including polymerized monomers of a diisocyanate and a diol. The diol can include to terminal 6-hydroxyhexanoate groups linked by an organic linking group. Chain extenders can connect the prepolymer segments. The chain extenders can include a polymerized diamine.

A white ink jet ink composition according to the present disclosure includes hollow resin particles, resin particles, and water. The hollow resin particles have a glass transition temperature of 120° C. or more, the resin particles are composed of an acrylic resin or a urethane resin, and the content of the resin particles is 5% by mass or more relative to the total mass of the ink composition.

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.

An example of a white inkjet ink includes a non-self-dispersed white pigment; an anionic cellulose; a polymeric binder; and an aqueous vehicle. The anionic cellulose is present in an amount ranging from about 0.01 wt% to about 5 wt% based on a total weight of the white inkjet ink. The white inkjet ink may be used in a textile printing kit.
