Influence of Components on the Properties of Pigment Inks for Textiles
Abstract:For inkjet printing, pigment inks are suitable for all kinds of fibre, the printing procedure is simple without both pretreatment and after-treatment. In the future, the research and development of pigment ink will be the main trend of the inkjet printing technology. In this paper, the influence of polyhydric alcohol, surfactant, de-foaming agent on ink performance, such as viscosity, surface tension and so on, was analyzed. The com- patibility of polyhydric alcohols such as 1, 3-propanediol, diethylene glycol, 1, 6-hexylene glycol, glycerine with pigment ink has been researched, and effect of the amount of polyhydric alcohols on the viscosity and surface tension of ink was discussed. The function of surfactants OP-7,OP-10 and OP-15 in ink has been analyzed, the results show that surfactant OP-7 and OP-10 could decrease the surface tension of inks below 30mN/m when the amount used about 1.0% or lower by weight. The efficiency of reducing surface tension falls down in the sequence of the surfactants OP-7, OP-10 and OP-15. The effect of the amount of surfactant on the viscosity was not very significant. The defoaming effect of n-butyl alcohol on pigment ink has also researched in this paper.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
