Method and apparatus for ink jet printing on textiles

This invention describes a method for printing multi-colored designs directly onto fabric using inkjet technology. It employs a special ink that is first partially hardened by ultraviolet light, and then fully cured by heat, ensuring very few unreacted chemicals remain in the printed fabric to meet strict safety standards. The patent specifically describes integrating this printing process into a quilting machine.

Why it matters: Filed before the widespread adoption of efficient UV LED curing technology. Modern UV LEDs offer more precise, energy-efficient, and compact curing, potentially simplifying the two-step process and improving safety.
