UV curable invisible inks and UV Curable Hydrogels demonstrated at Techtextil

ChemStream was present at the TechTextil Fair in Frankfurt and shared the booth (3.1-A01) with the Textile Research Department of the College of Ghent (TO2C).
Els Mannekens (from ChemStream) demonstrated the digital printing of UV-curable ‘invisible’ inks on textile using an experimental printing setup that consisted of a piezo printing head filled with ‘invisible’ ink, a UV-curing LED lamp and a transporting belt. Two main messages were thereby transmitted to the public: the simplicity of UV-curing technology for digital printing (no after-treatment, fixing or drying processes are needed afterwards) and our expertise in the development of specialty inks and coatings.

Many visitors were attracted by the printing setup, the printed samples and the activity at the booth, and many learned about UV-curable printing technology for the first time.

UV curable invisible inks

The fact that the invisible prints become visible under black light was a pleasant surprise to many of them and triggered their own creative ideas. This concept could be useful against counterfeiting practices (for brand clothing, etc.), tracking & tracing purposes and for special features in nightlife surroundings (disco, theater, etc.)


The features of a new UV-curable hydrogel coating applied on yarns or tissues were also illustrated. This new hydrogel coating can absorb up to 500 times its own weight and can be reused due to a 100% reversibility.
