Abstract

Pigment printing process for flame-retardant, low-flammability or nonflammable fibers On being printed with conventional pigment print pastes low-flammability fibers lose their flame-retardant properties in the areas covered with the print paste. It was therefore necessary to find a binder system which itself has low-flammability properties. By using polymers and/or copolymers of vinylidene chloride as pigment binder system the low flammability of such special types of fiber is not impaired.
