Digital inkjet printing is a production technology with high potential in resource efficient processes, which features both flexibility and productivity. In this research, waterborne, fluorocarbon-free ink containing polysiloxane in the form of micro-emulsion is formulated for the application of water-repellent sportsand work wear. The physicochemical properties of the ink such as surface tension, rheological properties and particle size are characterized, and thereafter inkjet printed as solid square pattern (10 9 10 cm) on polyester and polyamide 66 fabrics. The water contact angle (WCA) of the functional surfaces is increased from \ 90°to ca. 140°after 10 inkjet printing passes. Moreover, the functional surface shows resistance to wash and abrasion. The WCA of functional surfaces is between 130°and 140°after 10 wash cycles, and is ca. 140°after 20000 revolutions of rubbing. The differences in construction of the textile as well as inkfilament interaction attribute to the different transportation behaviors of the ink on the textile, reflected in the durability of the functional layer on the textile. The functionalized textile preserves its key textile feature such as softness and breathability. Inkjet printing shows large potential in high-end applications such as customized functionalization of textiles in the domain of smart textiles.

“…Some of these droplets become charged as they pass through an electrostatic field before passing through a second electrostatic field, causing charged droplets to deflect towards the printing medium (Needham Coding, 2020). Polymer degradation has been observed as a result of bioink recycling during CIJ (Wheeler et al, 2014). This could have significant implication for scale up activities, including loss of a large amount of material and therefore this method should be carefully considered for large-scale activities.…”

“…97 Finally, Wheeler et al compared CIJ and DOD in terms of polymer degradation. 99 They concluded that, even though CIJ displayed the same strain rate magnitude, degradation occurred in the recirculation system of the ink and not in the nozzle. With its digital and versatile nature, a growing interest from industries, and direct evidence of polymer scission events, inkjet appears a key technology to deliver patterned mechanochemistry at an industrial scale.…”

Polymer mechanochemistry is an exciting, rapidly developing field; however, it lacks detailed studies on the link between lab-scale mechanical activation and how the chemistry will translate to the complex flows and forces experienced during fluid-based molding and additive manufacturing techniques. This is especially important for polymers, which are the functional material of choice for applications such as organic electronics, biological scaffolds, and drug-delivery coatings, because there is the highest likelihood of mechanical activation. This review examines the most recent development in force-sensitive molecules known as mechanophores by re-categorizing them by material phase and method of activation and discussing the forces involved in such flow systems and where activation may occur in relevant manufacturing processes. The overall finding of this review is that for real, practical, and scalable industrial applications of these exciting mechanochemical materials, there must be a concurrent study of the forces experienced and their effect on the detailed chemistry.
