Digital textile printing can save waste, water and CO2. Covestro and Kronos are working together on binders and polyurethane dispersions for inkjet textile printing.

Kronos inkjet textile printing
The water-based pigment concentrate Kronos 9900 Digital White is compatible with the INSQIN polyurethane binders from Covestro. The new development from Kronos also meets the requirements of inkjet applications for maximum stability in the bottle, in the drum, in the print head, during the spraying process and on the substrate (Image: Covestro / Kronos)

Covestro and Kronos are working together on solutions for digital inkjet printing on textiles. Tests have now shown that Covestro's water-based INSQIN portfolio is compatible with the white pigment dispersion Kronos 9900 Digital White. No significant sedimentation was observed and all formulations showed good stability even after four weeks of testing at 50 degrees.

Covestro has also developed a new polyurethane dispersion, Impranil DL 1606, which targets the problem of sagging - a quality issue resulting from the relatively high quantities of ink required for transfer printing (DTF printing). The anti-sagging properties of the new binder make it particularly suitable for white pigment inks in inkjet printing.
