Direct Inkjet Single Sided Hydrophobic Finishing of Textiles
Abstract:Recent advances in the study of digital printhead-ink-substrate interaction, coupled with developments in printhead technology, have widened the tolerance for inkjet printing non-ideal fluids. A broader range of rheological profiles can now be jetted reliably, offering new commercial opportunities, particularly for digitally printing textiles. This advancement goes beyond just decoration, scope now exists to deposit a wide range of functional materials, including those already used in conventional processes, offering the prospect of new concepts and possibilities. As such, there is now greater emphasis on the development of inks that can functionalise textile substrates by inkjet deposition.
In this work, we have formulated inks incorporating fluorocarbon, based on C8 and C6 chemistry, to demonstrate that by combining the right chemistry with suitable components, many commercially available materials can be formulated into a reliable inkjet fluid. We have also studied the effect of digital hydrophobic finish on both sides of the printed fabric, and quantified this hydrophobic effect by measuring the contact angle and spray rating test. Wash durability and comfort relevant properties were also assessed. This data has improved our understanding of digital textile finishing and its unique benefits.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
