Two technologies are promissing for the future of textile pigmentary
printing. On the one hand, the non—polluting UV or EB technology which
is already used to cure pigrnentary prints, particulary for reduce energy
consumption, speed up this fabric finishing process and improve fastness
of the prints. And on the other hand, the ink—jet technology for textile
printing which is developing quickly and presents great avantages in
comparison with screen printing 6,7 : no more screen to engrave and stock,
so more flexibility and greater variety in color for the same pattern,
no design limitation and quick response (instantaneous pattern and color
change—over thanks to print capability directly from computer aided design
system memory).
That's why aqueous pigmented UV — and EB — curable printing inks have
been developed for textile continuous deviated ink—jet printing. This
paper discusses the copolymerization of the two binder systems selected
for the ink formulations for textile pigmentary printing.
