Effects of Particles on Drop Impingement

摘要

In traditional ink-jet-printing technology, dye-based inks are primarily used. To satisfy the demands of printing on textiles, there is a need for inks containing binder and pigment particles. While progress has been made in developing particle-laden inks for use in inkjet printers, little effort has been made to understand in detail the role of particles in the overall process. In fact there is little in the refereed literature about drop formation, impaction, and spreading phenomena for particle-laden liquids although these processes have been studied extensively in the past for pure liquids. A study of the spreading dynamics of a particle-laden drop impacting a surface will be presented.
