Synthesis and characterization of aqueous UV-curable binder for ink preparation in ink-jet printing and pigment dyeing of fabrics

An aqueous UV-curable binder of polyurethane acrylate based on glycerol ethoxylate-co-propoxylate triol has been prepared for ink preparation in ink-jet printing and pigment dyeing of cotton, viscose, wool, polyester and nylon 66 fabrics. Polyurethane acrylate oligomers have been prepared from isophorone diisocyanate, glycerol ethoxylate-co-propoxylate triol and hydroxy ethyl acrylate using dibutyl tin dilaurate as a catalyst. The results show that the binder can be used safely in preparing ink for ink-jet printing and/or for dyeing by padding technique for all types of fabrics with pigment dyes.
