The Development of New Disperse Dye Inks for Inkjet Textile Printing
نویسندگان
چکیده
Disperse dye inks are used in the inkjet textile printing of polyester fabrics. We aimed at developing a black disperse dye ink consisting of yellow, magenta, and cyan dyes that met the exacting requirements of safety, image durability, and storage stability. One difficulty we met was dye particles tending to aggregate/agglomerate, leading to sedimentation and the threat of head clogging and/or inferior color reproduction. We discovered that rapid adsorption and desorption exchange of dispersants and the wetting ability of the dyes’ surfaces appeared to control the system's stability. Based on this, we succeeded in developing a stable black disperse dye ink.
