ROLE OF ADDITIVES IN OPTIMISATION OF INKJET INKS FOR PRINTING OF TEXTILES
As of the few years ago, the Evonik Coating Additives laboratories are equipped with the ImageXpert drop watcher and the custom-made print station. The setup allows visualisation of the spreading behaviour of droplets soon after being fired from industrial printheads. The method developed on the described instrument allows the coverage ratio of the substrate by the ink to be quantified with respect to time, which gives way to determining differences between ink systems formulated with chemically different substrate wetting agents. In this talk, case studies that show how a selection of a wetting agent, and the pre-treatment of the substrate influence the kinetics of droplet spreading behaviour will be presented.

FROM VISION TO REALITY: BRIDGING GAPS IN DIGITAL TEXTILE PRINTING
Printing digitally on textiles without any effluent in a highly automated environment is currently a reality for just a few visionary companies. Business pragmatists in contrast might appear to be slow to cross the chasm and fully embrace the digital opportunity to the same degree. This talk sheds light on these pragmatists and some of their reasoning. Why ink types and sustainability play a crucial role will also be discussed, followed by examples where the industry has either already or still needs to bridge the gaps.

TURNING A DINOSAUR TEXTILE INDUSTRY INTO A CLEANTECH INDUSTRY
Within the textile sector, the single worst contributor to climate change is dyeing and finishing. By 2050, it is predicted that carbon emissions from dyeing and finishing textiles will rise threefold to more than two gigatonnes of CO2 annually, making it one of the most polluting industries on the planet. In addition, soaring energy costs combined with demands from brands and consumers to improve supply chain sustainability means the way textiles are dyed and finished needs to urgently change. This session explains how two disruptive digitally controlled dyeing and finishing products will enable a complete transformation of the textile industry. Endeavour dramatically reduces carbon emissions by cutting water used in the dyeing process by 95%, eliminating post-dye washing from the dyeing process. Novara finishing technology utilises digitally controlled nozzles to deliver precise high-value fabric enhancing finishes exactly where they are wanted while cutting water, chemicals, and energy.

VIVIDYE: REMOVABLE TEXTILE PRINTS
The Vividye innovation is a removable textile print that enables reuse of textiles. The innovation is strictly speaking a two piece system, including both the print and the removal of the print. It promotes consumer reuse, and influences behaviour change to utilise textile garments to their fullest lifespan before recycling. The print is developed to be functional in the exciting infrastructure of textile printing machines. The purpose of Vividye is to re-define printing on textile to re-integrate used textiles in the value chain, to increase the lifetime of clothes and provide opportunities for upcycling, while also enabling efficient material recycling when the textile is reaching end of life.

ACCELERATING THE SHIFT TOWARDS SUSTAINABLE PRINTING TECHNOLOGIES ACROSS TEXTILE MARKETS: POLYURETHANES AS AN ENABLING MATERIAL SOLUTION
To continue on its current trajectory towards a more sustainable industry, innovation is needed in the textile printing space. As a new and yet unproven disruptive technology, digital textile printing with pigment inks has gained attraction. However, the technology requires advanced material solutions and more often than not forces a re-evaluation of the suitability of standard raw materials employed. A material of choice for printed textiles are polyurethane raw materials due to their high flexibility, soft handfeel and excellent light fastness. Can this proven and highly versatile material class be successfully employed to solve the challenges of digital textile printing and hence accelerate the shift towards a more sustainable textile printing world? This question will be answered by highlighting a toolbox for the development of high performance pigment inks for multiple textile markets.

NOVEL AQUEOUS WHITE PIGMENT CONCENTRATE FOR INKJET APPLICATIONS
The share of digital printing technologies is significantly increasing with double digit growth numbers. There is an increasing necessity for white TiO2 pigments, primarily in textile and packaging applications. Especially in DTG and DTF textile applications, printing white based on KRONOS 9900 exhibits highest opacity and whiteness on dark substrates. KRONOS developed a novel aqueous white pigment dispersion which fulfills the highest level of technical requirements, such as a wide range of compatibility with various types of binders and additives in formulations, a short filtration time and an excellent storage stability of inkjet inks. The recently released white pigment concentrate is in compliance with Swiss Ordinance and Nestlé guidance regulatory.

SMART PRINTING FOR SMART PRODUCTS: USING CONDUCTIVE SCREEN PRINTING AND FUSED DEPOSITION MODELLING ON TEXTILES TO CREATE SMART TEXTILES
Additive manufacturing technologies allow for creation of smart textile products by combining textile and non-textile components and thus extending range of functions. By using conductive screen-printing technology with conductive pastes textiles with integrated electrical intelligent functions are created. By this functional printing and creating electronics circuit boards on textiles it is possible to create unique and innovative human-machine interaction with solutions for monitoring, detection, lighting, heating, data exchange, etc. Using different material combinations by use of fused deposition modelling, the development and obtaining textiles materials with unique hybrid features is possible. An example of this are 4D textiles that can change their form and function over time to adapt to their environment and the needs of their users. This change is generated by the complex interaction between hybrid materials and the use of external stimuli.

FUNCTIONALISATION OF TEXTILE SURFACES USING DIGITAL PRINTING TECHNOLOGIES
Textile finishing improves performance of textile substrates by implementing functions such as water repellency, UV-protection, flame-retardancy etc. in the textile substrate. The traditional application is done in full width using padding equipment. This technology is very high in consumption of chemicals as well as it is not flexible as demanded for the production of small orders. In contrast, digital printing technology enables saving of chemicals, because the finishing chemicals are applied only to the areas that are needed for the finished textile. Inkjet printing has significantly developed within the last few years and now represents a future oriented and very fast and flexible application technology. The development and availability of functional inks provides a new way in finishing and functionalisation of textile materials using digital printing technology. A number of newly developed functional inks will be presented as well as their possibilities and limitations in digital functionalisation. A vision of digital finishing will be presented and the potential of creating very new textile products such like digital printed smart textiles (and others) will be shown.

KEYNOTE: COURAGE! A PLEA FOR A GOOD FUTURE
For more than 40 years we have known where our way of life is leading us. What have we done in all that time? The shameful answer: nothing! Now that the impacts are approaching in the form of catastrophes and climate change is becoming tangible for everyone, we are slowly getting an inkling of how radical the change will be for all of us. The challenges for which solutions have to be found are gigantic. That can be frightening. But fear has always been a bad advisor. It paralyses and prevents us from seeing the huge opportunities that arise from transformation. The existing systems are changing socially, politically and economically towards green and social ones. The transformation is gaining momentum. And that is a good thing. Because we can all only gain. The speaker makes a plea for transformation and takes you on a hopeful journey to a world worth living in tomorrow.

KEYNOTE: GLOBAL ORGANIC TEXTILE STANDARD: FOR THE PEOPLE AND THE PLANET
GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria. Having one common standard means textile processors and manufacturers can export their fabrics and garments with one organic certification that is accepted in all major markets. This transparency also gives consumers the power to choose truly organic products sourced from green supply chains. GOTS does not only support better production but also creates the valuable and so often missing link between producers, buyers and consumers. The presentation will give insights about the implementation of GOTS criteria, their contribution to sustainable development and essential connections along the supply chain.

HOW CAN INKJET PRINTING HAVE AN IMPACT ON REACHING OUR SUSTAINABLE GOALS
The textile industry is one of the biggest industries in the world. The production of textiles has continuously shifted to places which are cheap in terms of production costs, while the brand owners are based and headquartered somewhere else. In those countries, where most of our textiles are produced, the regulations for a clean, safe and healthy production are not on the same level as we have them here in Europe. Furthermore, there is a lot of clean water needed to obtain a nice-looking garment, while the source of fresh water in those countries is very limited as well. Druckprozess has dedicated a lot of effort to answer the question of how can a disruptive technology like inkjet tackle those circumstances. There are two answers, one for the decorative printing and one for the chemical treatment of fabrics.

UNDERSTANDING TEXTILE INKJET INKS AND FACTORS INFLUENCING THE JETTING BEHAVIOUR
Fundamental understanding of ink chemistry, formulations and influence of individual components and ink as-a-whole on dynamic flow behaviour in-channel, nozzle, in-flight and on-substrate during printing is vital to control print quality (drop ejection characteristic, reliability) and further advances in the capability of inkjet technology. We will discuss recent advances in inkjet ink chemistry and physics and will provide an overview of textile inkjet inks, how and where individual ink components influence the jetting behaviour during printing. Physical properties alone are no guide to ink jetting performance. Small variations in ink viscoelasticity influences upstream flow dynamics and jet break-up mechanism downstream. We will present bespoke extreme rheological tool TriPAV & TriMaster capable of quantifying complex fluid rheology of low viscosity textile inkjet inks at conditions similar to those during inkjet printing. This provides useful tools to differentiate between apparently identical inks but that show different jetting behaviour. This is often the case, where ink batch variations or minor formulation alteration causes different jetting behaviour and influence print reliability. Understanding the influence of these dynamic properties of inkjet inks will aid formulating and fine-tuning reliable high viscosity inkjet inks and speed up waveform development.

BRIDGING THE GAP TO SUSTAINABILITY IN TEXTILE PRINTING: ASSESSING THE CURRENT LANDSCAPE AND INK CHEMISTRY STRATEGIES TO MEET THE MARKET CHALLENGES
The textile industry has been pressured to reform and consider the use of chemicals and resources such as water and energy for a number of years with many leading brands introducing sustainability commitments and standards to reduce the overall impact of textile decoration on the environment. This coincides with a clear change in attitude from consumers who are making more environmentally conscious decisions about how and what they buy. This leaves the brands and their downward supply chain with challenges in how they manage material, chemistry and technology inputs to meet the demands of the market. This talk will look at the industry trends, the impact they have on printers, the challenges of sustainability and how digital printing is placed to meet them.

KEYNOTE: DIGITAL FASHION AND TEXTILES, A CHALLENGE AND OPPORTUNITY FOR INDUSTRY AND EDUCATION
The European textile and clothing industry is very diverse and heterogenous. It covers numerous activities and plays a major role in the European manufacturing industry. The sector stands out on the global market for its quality and innovations in both fashion products and smart and technical textiles. One important aspect to maintain this innovation drive, and at the same time tackle the sustainability problems of the sector, is the digitization of the design and production processes. Furthermore, the COVID 19 pandemic has stressed the need for virtual counterparts. Therefore, the demand for highly qualified and skilled personnel is increasing. They are the key to competitiveness and growth in the sector. However, digitization and sustainability not only challenge the industry, but also education. A healthy Nexus between research and education is the key to training future-oriented professionals.

DIGITAL MANUFACTURING APPROACHES FOR RESOURCE-SAVING TEXTILE FUNCTIONALISATION
Digital and contactless manufacturing methods are an enabling technology for novel resource-saving production processes. Applying conventional printing methods like screen, flexo or gravure printing of a patterned application of functional materials onto the textile substrate is possible but there is always a need of a printing master. Whereas digital technologies have the possibility to apply functions customized, mask-, contactless and on three-dimensional textile surfaces. This is the reason digital manufacturing approaches like UV-laser imaging, drop-on-demand printing and single nozzle jet dispensing will lead to novel design possibilities and functionalities.
Dr Frank Siegel, Saxon Textile Research Institute
RESOURCE EFFICIENCY THROUGH DIGITISATION
Digital printing technologies are a cornerstone of digital textile microfactories. Such microfactories offer a wide range of use cases and possibilities for resource efficiency and sustainability. The presentation will thus focus on the following aspects:
- Material flow and cost accounting (MFCA) and life cycle assessment (LCA) offer are suitable methods to model, analyse and evaluate processes. In terms of resource efficiency and sustainability
- Digital textile microfactories are a platform for digitally consistent processes. This modular concept can be realised by suitable workflows, process integration and according business models.
- The benefits of such concepts comprise the design and production of individual products for better fit and acceptance. The regional production produces less waste and requires less transport.
- A technical analysis of different printing setups in terms of inks and fabrics is necessary so select the best combination for the use case at hand. With a multi-criteria analysis: Ecological and economic criteria can be weighted and combined for best results.
SUSTAINABILITY IN THE TEXTILE INDUSTRY: WHERE DO YOU GO WITH UN GOALS, CIRCULAR ECONOMY, REACH AND ECO LABELS?
In the future, reconciling ecology and economy will be the major challenge along the entire textile chain. Many companies are committed to the 17 UN-SDG, the circular economy and hold numerous certificates from eco-labels, knowing that they have a responsibility towards future generations. In the lecture, these aspects will be examined in more detail and examples of successful combinations and compromises in this area will be presented.
