“…Nanotechnology plays a very important role in the developing of novel highly-functional and protective textiles by providing flexibility, stretchability, permeability, lightweight and durability to the fabrics, with significantly increased levels of functionality/protection and improved comfort (Krifa and Prichard, 2020). This trend also goes in the direction of environment and user friendly products, which, however, are still challenging and difficult to achieve.…”

Low moisture absorbency of hydrophobically coated flame-resistant (FR) fabrics do not correlate well with the thermophysiological comfort. In this frame, we were the first to study the effect of screen-printed microfibrillated cellulose (MFC) on fabric’s breathability and moisture build-up and transfer as user-friendly and wear-related comfortable coating. The amount of MFC applied and its patterning was varied using different printing parameters, the density and thickness of FR fabric, and studied by add-on measurement and microscopic imaging. The effect of MFC coating and its durability (attachment) after a post-printing of hydrophobic polyacrylate on the same (layer-by-layer) or other side of the fabrics was considered, thus to maintain one side of the fabric (facing towards the wearer) hydrophilic while keeping the other side (facing outward) hydrophobic. The results showed that MFC provides uniform and repeatable printing, which gave homogeneous patterning with good layering on the fabrics, although, resulting in the MFC concentration, squeegee’ pressure, and fabric’ structure dependent add-on, its imprinting and co-crosslinking within the polyacrylate. This slightly reduced the fabric air-permeability, but increased it surfaces wetting, moisture uptake kinetic and capacity (hydroscopicity), without affecting the water vapour transfer. Besides, the polyacrylate could fix the MFC pre-printed on the other side of the fabric, thus maintaining its hydrophilicity, being more pronounced in the case of less open and thicker fabric, while improving its tensile/tear strengths and abrasion resistance, without deterioration of the fabric`s flammability.

“…Other than the widely used carbon fillers discussed above, textile structures with metal nano-additives have also been extensively documented with a broad range of ap- Nickel is another metal that has been reported in research to impart electrical conductivity to textile structures using both coating and nano-filling approaches [130][131][132][133][134][135]. As a nano-filler, nickel has been commercialized in the form of nanostrands (NiNs) with a branched 3D structure (Figure 11) generated by chemical vapor deposition [132,[136][137][138]. The branched 3D structure has been cited as an advantage of NiNs over other nanofillers (including carbon and metals) in terms of electrical conductivity because it enables more interconnects and thus more conductive pathways within the polymer matrix [136, [139][140][141].…”

This paper reviews some prominent applications and approaches to developing smart fabrics for wearable technology. The importance of flexible and electrically conductive textiles in the emerging body-centric sensing and wireless communication systems is highlighted. Examples of applications are discussed with a focus on a range of textile-based sensors and antennas. Developments in alternative materials and structures for producing flexible and conductive textiles are reviewed, including inherently conductive polymers, carbon-based materials, and nano-enhanced composite fibers and fibrous structures.
