Abstract: 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.

Abstract: In an example of a textile printing method, a thermally curable ink composition is applied on a fabric substrate. The thermally curable ink composition includes from about 1 wt % active to about 6 wt % active of a pigment that absorbs ultraviolet radiation, infrared radiation, or a combination thereof, based on a total weight of the thermally curable ink composition; from about 2 wt % active to about 20 wt % active of a polymeric binder, based on the total weight of the thermally curable ink composition; and an aqueous ink vehicle. In the method, the pigment of the thermally curable ink composition is selectively heated on the fabric substrate by exposing the fabric substrate to an emission wavelength from a narrow wavelength light source for a total exposure time of 3 seconds or less. The selective heating thermally fixes the pigment to the fabric substrate.

Abstract: A fixer composition includes a polyamine; a phosphate ester surfactant; a co-solvent; and a balance of water. The polyamine is selected from the group consisting of an azetidinium-containing polyamine, an epoxide-containing polyamine, and combinations thereof. The co-solvent contains two hydroxyl groups and an aliphatic chain between the two hydroxyl groups, the aliphatic chain containing three carbon atoms. The fixer composition may be used in combination with an inkjet ink and may be included in a fluid set and/or a textile printing kit.

Abstract: In an example of a method for printing on a textile, a print is generated by thermal inkjet printing a thermal inkjet ink on a cotton fabric. The thermal inkjet ink consists of a pigment, a single dispersant and binder resin, a vehicle, and a balance of water. The single dispersant and binder resin is a styrene acrylic resin having an acid number greater than 100 mg KOH/g and a weight average molecular weight less than 50,000. The vehicle includes a co-solvent, an anti-kogation agent, a humectant, a surfactant, a biocide, or combinations thereof. The print is generated without a post-printing curing process.
