“…The friction between the liquid phases is decided by the cohesion between molecules, which can explain the change in viscosity. 13 Hence, the viscosity reflects the friction between the molecules inside the liquid. The dependence of viscosity on the concentration of DEG is described in Figure 7.…”

“…As a new technology, there are many technical difficulties to overcome in the actual production process of ink-jet printing. − For example, ink droplets cannot be ejected due to insufficient wetting of the nozzle during the ink-jet printing process. , In the process of designing ink formulation, the proportion of organic solvents is relatively large . Satellite ink droplets are more likely to form at high jetting frequency, resulting in lower image resolution on the fabric and air pollution. , …”

Fabric ink-jet printing is a crucial technology of clean production in the textile industry. Reactive dyes and organic solvents are the important component of ink-jet printing ink. The structure, hydrophobicity, and aggregation degree of reactive dye affect the amount of organic solvent and ink droplets spread on fabric, which is essential for reducing organic solvent dosage and obtaining high quality ink-jet printing images on fabric. In this study, two red reactive dyes (reactive red 218 dye and reactive red 24:1) with different structures were used to prepare reactive dye solutions, which were subsequently explored by investigating the surface tension, rheological properties, visible absorption spectra, and droplet formation and observing the spreading behavior on cotton fabrics. For the first time, the effects of dye hydrophobicity on organic solvent dosage and ink-jet image resolution were studied. The results showed that reactive red 218 dyes possessed stronger hydrophobicity and more compact aggregation. Reactive red 218 clusters were more easily disaggregated into dye monomers through the hydrophobic interaction between the DEG and dye molecules, while reactive red 24:1 clusters were disaggregated into small clusters. Reactive red 218 solution droplets were more stable, which could reduce the air pollution caused by the satellite droplets. Based on the above reasons, the solution of dye with stronger hydrophobicity required less organic solvent and had a smaller droplet spread area (represents higher printing resolution) on the fabric. These findings provided a novel direction for reducing organic solvent consumption and improving the utilization rate of dye solution.

“…These properties have led to the exploitation of perylenes in various applications such as organic field-effect transistors, thin-film transistors, complex supramolecular systems, and, increasingly, organic photovoltaics (OPVs) [20,21,22]. The recent development of a new class of perylene dyestuffs (KREMER, Berlin, Germany) has renewed the interest of researchers in different fields of industrial applications due to its unique photophysical properties such as long-distance energy transfer when doped in polymeric matrices, the ability to transmit light in the absorption range of the luminescent material, and excellent long-term thermal and photostability [23]. There are specific spectral requirements for the light that enters greenhouses, which is an important factor for each plant.…”

Luminescent polymethylmethacrylate (PMMA) films were prepared by the solvent-casting technique from polymer solution doped with different concentrations of red perylene dyestuffs (KREMER 94720 and KREMER 94739). The effect of the dye concentration on the structure and spectroscopic properties was studied using X-ray diffraction (XRD), transmission electron microscope (TEM) optical absorption, and fluorescence spectroscopy. The optimum dye concentration of photoselective PMMA films was determined by the fluorescence spectroscopy measurements and showed the best emission properties for the doping concentration 10−3 wt % of the investigated dyes. The accelerated photostability tests showed promising stability of the prepared films towards terrestrial solar ultraviolet radiation (UVA). The results endorsed a promising application of the investigated films in photoselective greenhouse cladding applications as the optimized film fluoresces at the action spectra of special chlorophyll a.

“…The clothing industry demands faster printing processes and on minor scales to meet and keep up with fashion designs. Another major challenge for the textile industry is the search for a less environmentally damaging process-for example, the conventional dyeing process uses a lot of energy and a large volume of water and also has the need for effluent treatment [1,2]. Digital printing offers solutions for various textile materials.…”

Digital Sublimation Printing on Knitted Polyamide 6.6 Fabric Treated with Non-Thermal Plasma

The garment industry demands stamping processes that are increasingly more agile and less damaging to the environment. In this scenario, digital printing, with the sublimation transfer printing technique, presents itself as a viable option for synthetic textile substrates. Among the synthetic fibres, polyamide (P.A.) fibres stand out, as they are light, soft, durable, and boast moderate sweat absorption; however, before sublimation, superficial treatment is necessary in order to present good results such as withstanding washing and maintaining colour intensity. This study addresses the surface modification of the PA6.6 textile substrate by activating non-thermal plasma at atmospheric pressure to receive dye through the sublimation method with dispersed dye. The knitted PA6.6 fabric surface treatment was performed with plasma application at atmospheric pressure using air in the Plasmatreater AS400 equipment. The sublimation transfer effects were evaluated by wash fastness and colourimetric tests. To assess the wettability effect of the control and treated samples, a contact angle test was carried out on PA6.6 samples. Fourier transform infrared spectroscopy (FTIR) proved the changes in chemical functional groups in the fibres. The results showed a decrease in the contact angle of the textile surface, 4–5 grayscale results for colour change and transfer for washing, and an increase in colour strength. In the FTIR tests, there is an increase in the transmittance value of aromatic, carboxylic groups (C=O, 580 cm−1), amides (N=H, 1630 cm−1), and methyl groups (CH 1369 to 1463 cm−1) as well as the presence of new functional groups in the 3064 cm−1 and 2860 cm−1 bands. These conditions allowed sublimation in the knitted PA6.6 fabric and showed increased colour strength and good wash fastness.
