“…Although reactive red 218 has a similar structure to reactive red 24:1, one crucial difference between the two dyes is the size of the hydrophobic portion, which is equivalent to the difference in hydrophobicity. At present, cotton fabric is widely used in industrial production. − Figure shows microscopy observation of printed cotton fabrics, and images were composed of four ink droplets sprayed in the same position by ink-jet printing.…”

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.

“…As shown in Figure 7, the surface of the untreated polyester fibers is relatively smooth at low magnification with a uniformly distribution of the coating. Meanwhile, it can be clearly observed that there are many tiny grooves and many little protrusions on the surface of the treated polyester fabric fibers at high magnification which provide a nano-scaled roughness, supporting the superhydrophobic behavior of the treated fabrics [56].…”

Polyester fibers are widely employed in a multitude of sectors and applications from the technical textiles to everyday life thanks to their durability, strength, and flexibility. Despite these advantages, polyester lacks in dyeability, adhesion of coating, hydrophilicity, and it is characterized by a low wettability respect to natural fibers. On this regard, beyond the harmful hydrophobic textile finishings of polyester fabrics containing fluorine-compounds, and in order to avoid pre-treatments, such as laser irradiation to improve their surface properties, research is moving towards the development of fluorine-free and safer coatings. In this work, the (3-glycidyloxypropyl)trimethoxysilane (GPTMS) and various long alkyl-chain alkoxysilanes were employed for the fabrication in the presence of a catalyst of a water-based superhydrophobic finishing for polyester fabrics with a simple sol-gel, non-fluorinated, sustainable approach and the dip-pad-dry-cure method. The finished polyester fabrics surface properties were investigated by static and dynamic water repellency tests. Additionally, the resistance to common water-based liquids, abrasion resistance, moisture adsorption, and air permeability measurements were performed. Scanning electron microscopy was employed to examine the micro- and nano-morphology of the functionalized polyester fabrics surfaces. The obtained superhydrophobic finishings displayed high water-based stain resistance as well as good hydrophobicity after different cycles of abrasion.

“…Plasma surface modification is a versatile and efficient approach to process a wide range of materials such as metals, ceramics, polymers, and composites to achieve desirable properties, such as surface wettability, mechanical attributes, and thermal properties [17][18][19]. Generally, the complementary properties for a biomaterial include biocompatibility and antimicrobial properties without influencing the substrate's well-optimized bulk characteristics by surface etching, surface grafting, coating, and activation [20 ].…”

Modern society is suffering from many infectious microbes. Developing antimicrobial surfaces for biomedical decontamination and sterilization is one of the strategic solutions to mitigate the spread of infectious pathogens. Here, we outline the paradigm of plasmas for biomedical decontamination by presenting approaches of plasmaengineered antimicrobial surfaces and novel plasma-active antimicrobial surfaces. Low-temperature plasma can not only be used as a material fabrication tool for antimicrobial surface engineering but also be used directly for microbial inactivation by specially designed plasma-active surfaces that can effectively destroy microorganisms through exposure to plasma. The role of plasmas in the two different kinds of antimicrobial surfaces is discussed along with their associated advantages and disadvantages. Future research directions, challenges, and opportunities in both plasma-based antimicrobial surfaces are also critically evaluated. This analysis contributes to the development of next-generation antimicrobial surfaces for future bio-safety.
