This research mainly treats the color process of carbon polyester fiber which is effected by nanoized titanium dioxide material and the thermal printing, and investigated coloration, dyeing fastness to light fastness, rubbing fastness, washing fastness and resist germ of carbon polyester fiber. In this experiment, it is the point of fineness of fiber in the Sublimation process of the ink jet printing technology, and the appearance colouring density of commercial inks is affected by printing paper on inks, not particle size. appearance colouring density before nanoized titanium dioxide deal with fiber material is better than after, but light fastness, rubbing fastness, washing fastness are not.
