Abstract
Waterfast ink jet printing onto textiles is performed by treating the textiles with a polymer or copolymer of epihalohydrin prior to the ink jet printing process. A softener such as a tetraalkylammonium salt may also be used, as may be a cationic binder.
Claims17
A method of making a printed textile comprising the steps of:
- contacting said textile with a solution having total dispersed solid content of approximately 8% to approximately 35% by weight comprising (1) approximately 4% to approximately 25% weight solids epihalohydrin copolymerized with polyalkylene polyamine and (2) approximately 4% to approximately 10% weight solids softener comprising a quaternary ammonium salt in a ratio of approximately 1:1 to approximately 2.5:1 epihalohydrin copolymerized with polyalkylene polyamine to quaternary ammonium salt;
- drying said textile so as to form an ink acceptor layer on a surface of said textile;
- and
- ejecting ink droplets onto said surface of said textile.

A method of printing fabric comprising:
- coating said fabric with a solution comprising (1) a polymer or copolymer comprising an epihalohydrin or its precursors and a polyalkylene polyamine, (2) a softener comprising a tetraalkylammonium salt, and (3) an additional cationic binder different from both said polymer or copolymer of epihalohydrin or its precursors and a polyalkylene polyamine and from said tetraalkylammonium softener to form a coated fabric;
- and
- ejecting droplets of ink onto said coated fabric with an inkjet printer.
A method of printing on fabric comprising:
- treating the fabric with a solution comprising a polymer or copolymer comprising an epihalohydrin or its precursors and a polyalkylene polyamine;
- and a softener comprising an tetraalkylammonium salt;
- ejecting ink droplets onto said coated fabric with ink from an ink jet printer to print a pattern on said fabric;
- and
- repeating the step of ejecting droplets of ink onto said coated fabric to re-print said pattern on said fabric.

A method of printing on polyester fabric comprising:
- treating the polyester fabric with a solution comprising a polymer or copolymer comprising an epihalohydrin or its precursors and a polyalkylene polyamine and a tannin salt to form a coated polyester fabric;
- and
- printing on said coated polyester fabric with an ink jet printer.
A method of making a printed textile comprising:
- immersing said textile in a solution consisting essentially of (1) solvent, (2) a polymer or copolymer comprising an epihalohydrin or its precursors, and (3) a tetraalkylammonium salt softener;
- drying said textile;
- and
- ejecting ink droplets onto said textile.
