A textile printing system can include an ink composition and a fabric substrate. The ink composition can include water, organic co-solvent, from 0.5 wt % to 10 wt % pigment, wherein the pigment has a dispersant associated with a surface thereof, and from 0.5 wt % to 20 wt % latex particles including styrene (meth)acrylic polymer having an acid number from 0 mg KOH/g to 60 mg KOH/g and a glass transition temperature from −30° C. to 50° C. The latex particles are uncrosslinked.

A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

A black ink composition for inkjet printing that contains a water-soluble organic solvent, a resin emulsion, a dispersing agent, and at least four types of sublimation dyes. At least three of the sublimation dye types are C.I. disperse yellow, C.I. disperse red, and C.I. disperse blue, and at least one of the sublimation dye types has a maximum absorption wavelength in the wavelength band of 640 nm to less than 680 nm as measured from a visible spectral absorption of a solution obtained by dissolving the dye in acetone. An ink set for inkjet printing that includes the black ink composition for inkjet printing, and a method for printing on hydrophobic fibers that uses the composition and the ink set.

A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

Highly saturated scarlet dye ink for a high-speed inkjet process and a method of preparing the highly saturated scarlet dye ink are disclosed. In particular, an ink composition according to the present invention includes a dye including a compound represented by Formula 1, and further includes, in addition to the dye, distilled water, a surfactant, and an additive. The ink composition develops a highly saturated scarlet color that is unable to be developed by existing inks for digital textile printing (DTP), and has high water solubility, excellent heat resistance, and light-fastness, and thus may be effectively used as dye and ink for a high-speed inkjet process. ##STR00001##
