The present disclosure provides a moisture-sensed deforming fabric which includes a base cloth and a moisture-sensed shrinking ink. The moisture-sensed shrinking ink is jetted on one of surfaces of the base cloth by a digital printing process, and the moisture-sensed shrinking ink forms a hydrophilic region on the surface of the base cloth.

Aspects of the present disclosure relate to a printable medium including a polyurethane dispersion. As an example, a printable medium may include a fabric base substrate, with an image-side and a back-side. A film-forming layer may be applied to the image-side of the fabric base substrate, including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion. An ink-receiving coating layer may be applied over the film-forming layer, including a crosslink agent.

An ink, having a viscosity of 2.5 to 15 centipoise at 25° C., for textile printing includes pigment; a water dispersible anionic polymeric resin; a water soluble zero volatile organic compound solvent with a boiling point of 250° C. or greater; a crosslinking agent; and water. The water dispersible polymeric resin has particles with a median volume weighted size of less than 150 nm and a 95.sup.th percentile volume weighted size of less than 250 nm. The water dispersible polymeric resin has an acid number value of 5 to 40, a resin film elongation of 500 to 1200%, and a film tensile strength of 10 to 60 mPa.

A treatment liquid composition contains a water-resistant agent selected from a polyamide epihalohydrin polymer and dimethylpyrazole-blocked isocyanate, and a polyamine compound.

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.
