Definitions
- Textile printing methods often include rotary and/or flat-screen printing.
- Inkjet printing is a non-impact printing method that utilizes electronic signals to control and direct droplets or a stream of ink to be deposited on media.
- FIG. 1 is a schematic illustration of example multi-fluid kits and example textile printing kits, each of which includes an example of a pretreatment fluid and an example of a white inkjet ink;
- FIG. 2 is a flow diagram illustrating an example printing method
- Fig. 3 is a schematic diagram of an example of a printing system
- Figs. 4A through Fig. 4C are black and white reproductions of originally colored photographs of comparative prints (Fig. 4A and Fig. 4B) and an example print (Fig. 4C) on a first polyester fabric, illustrating a reduction in dye migration for the example print;
- Figs. 5A through Fig. 5C are black and white reproductions of originally colored photographs of comparative prints (Fig. 5A and Fig. 5B) and an example print (Fig. 5C) on a second polyester fabric, illustrating a reduction in dye migration for the example print.
- the textile is a major industry, and printing on textiles, such as cotton, polyester, etc., has been evolving to include digital printing methods.
- Some digital printing methods enable direct to garment (or other textile) printing.
- White ink is one of the most heavily used inks in direct to garment printing. More than two-thirds of the direct to garment printing that is performed utilizes a white ink on a colored textile.
- Obtaining white images with desirable opacity has proven to be challenging, in part because different textile fabrics introduce different obstacles that can affect the white print. As an example, cotton fabrics are more likely than polyester fabrics to have fibrillation (e.g., hair-like fibers sticking out of the fabric surface).
- polyester fabrics are more likely than cotton fabrics to have dye migration (e.g., dye from the underlying textile migrates out of the fabric surface when exposed to heat).
- Dye migration can color the white print.
- Systems that are designed for printing on polyester fabrics and reducing dye migration are limiting because they are not suitable for other textiles and they are cost prohibitive for the average consumer.
- a multi-fluid kit that is particularly suitable for obtaining white images, which may have desirable opacity, durability (i.e., washfastness), and quality.
- the multi-fluid kit include at least a pretreatment fluid and a white inkjet ink.
- Some examples of the multi-fluid kit also include a fixer fluid.
- the pretreatment fluid includes urethane water repellant, which has been found to improve opacity and image quality on both cotton and polyester textile fabrics.
- the urethane water repellant forms a film that imparts some hydrophobicity to the textile fabric.
- the urethane water repellant allows the pigment of the white inkjet ink to be fixed at or near the surface of the textile fabric, which improves the opacity of the white image that is formed.
- the film may be able to hold the hair-like fibers of the cotton textile fabric, which reduces fibrillation and improves image quality.
- the fluids in the multi-fluid set may be efficiently cured at relatively low temperatures in an oven, which can reduce migration of the dye from the polyester textile fabric to the surface of the textile fabric, which, in turn, reduces coloration of the white print.
- the opacity may be measured in terms of L* i.e. , lightness, of a white print generated on a colored textile fabric.
- L* is measured in the CIELAB color space, and may be measured using any suitable color measurement instrument (such as those available from HunterLab or X-Rite).
- the white inkjet ink when printed on the colored textile fabric pretreated with the pretreatment fluid and the fixer fluid disclosed herein, may generate prints that have a desirable L* value.
- the durability of a print on a textile fabric may be assessed by its ability to retain color after being exposed to washing. This is also known as washfastness. Washfastness can be measured in terms of a change in L* before and after washing.
- the fluid(s) and/or white inkjet ink disclosed herein may include different components with different acid numbers.
- the term “acid number” refers to the mass of potassium hydroxide (KOH) in milligrams that is used to neutralize one (1 ) gram of a particular substance. The test for determining the acid number of a particular substance may vary, depending on the substance.
- a known amount of a sample of the binder may be dispersed in water and the aqueous dispersion may be titrated with a polyelectrolyte titrant of a known concentration.
- a current detector for colloidal charge measurement may be used.
- An example of a current detector is the Mutek PCD-05 Smart Particle Charge Detector (available from BTG). The current detector measures colloidal substances in an aqueous sample by detecting the streaming potential as the sample is titrated with the polyelectrolyte titrant to the point of zero charge.
- a suitable polyelectrolyte titrant is poly(diallyldimethylammonium chloride) (i.e., PolyDADMAC). It is to be understood that any suitable test for a particular component may be used.
- wt% active refers to the loading of an active component of a dispersion or other formulation that is present in the pretreatment fluid, the fixer fluid, or the white inkjet ink.
- the white pigment may be present in a water-based formulation (e.g., a stock solution or dispersion) before being incorporated into the white inkjet ink.
- the wt% actives of the white pigment accounts for the loading (as a weight percent) of the white pigment that is present in the white inkjet ink, and does not account for the weight of the other components (e.g., water, etc.) that are present in the formulation with the white pigment.
- the term “wt%,” without the term actives, refers to either the loading (in the pretreatment fluid, the fixer fluid, or the white inkjet ink) of a 100% active component that does not include other non-active components therein.
- molecular weight refers to weight average molecular weight (Mw), the units of which are g/mol or Daltons.
- the viscosity measurements set forth herein represent those measured by a viscometer at a particular temperature and at a particular shear rate (s' 1 ) or at a particular speed.
- the temperature and shear rate or temperature and speed are identified with individual values.
- Viscosity may be measured, for example, by a Brookfield viscometer or another suitable instrument.

- a range from about 3 wt% active to about 40 wt% active should be interpreted to include not only the explicitly recited limits of from about 3 wt% active to about 40 wt% active, but also to include individual values, such as about 4.15 wt% active, about 12.5 wt% active, 14.0 wt% active, 26.77 wt% active, 38 wt% active, 39.33 wt% active, etc., and subranges, such as from about 5 wt% active to about 15 wt% active, from about 3 wt% active to about 25 wt% active, from about 10 wt% active to about 20 wt% active, etc.
- “about” is utilized to describe a value, this is meant to encompass minor variations (
