Digital printing white ink patent

Polytech applies for digital printing White pigment ink patent

Based on our vision to expand the application areas of coating inks, Polytech has employed a new pigment dispersion technology to attempt dispersing more titanium dioxide pigments into our self-synthesized resin. The stable presence of white ink is a decisive step in broadening the application range of water-based coating digital printing inks.

 

For both direct-to-garment (DTG) and transfer printing, we require extremely stable white ink, with white ink playing an especially crucial role in DTG applications. As is well-known, the currently popular Brother system requires prolonged cyclic cleaning before and after printing, due to the unique properties of white ink.

 

There is a certain contradiction between the covering performance of white ink and its smooth printing performance, and finding the optimal balance has always been a focus of the Polytech team's efforts.

 

 
POLYTECH applies digital printing white ink patent 1 

 

After extensive research and exploration, we have developed our own proprietary white ink formulation and have applied for a patent. This invention discloses a white digital inkjet ink for dark fabrics, which is formulated using a nano titanium dioxide dispersion and a nano water-based adhesive emulsion as the main components. The nano titanium dioxide dispersion is an aqueous emulsion formed by dispersing titanium dioxide through ultrasonic nanotechnology, while the nano water-based adhesive emulsion is also an aqueous emulsion formed by subjecting the water-based adhesive emulsion to ultrasonic nanotechnology. This invention uses the nano titanium dioxide dispersion and the nano water-based adhesive emulsion as the primary components of the formulation, effectively improving the smoothness and stability of white ink printing, making filtration easy and convenient. It thereby addresses the frequent need to replace filter cartridges during white ink filtration, reducing production costs.
