“…Previously, EVA has been applied in flexible electrical devices, such as spray-coated conductive films for solar cell electrodes [32], spin-coated transparent electrodes [33], screen-printed conductors for paper-based electronics [34], and a dip-coated conductive membrane for energy storage [35]. This environmentally friendly copolymer is also widely used in food packaging, as an encapsulation material for flexible photovoltaic devices [36], as a hot-melt adhesive [37], and as a flexible adhesive layer between textile insole pads [38]. EVA is soluble in organic solvents, including xylene [33], butyl acetate [32], toluene [39], and chlorobenzene [29].…”

Conductive tracks are key constituents of wearable electronics and e-textiles, as they form the interconnective links between wearable electrical devices/systems. They are made by coating or printing conductive patterns or tracks on textiles or by weaving, knitting, or embroidering conductive yarns into textiles. Screen printing is a mature and cost-effective fabrication method that is used in the textile industry. It allows a high degree of geometric freedom for the design of conductive patterns or tracks. Current screen-printed conductive textiles have the limitations of low durability when washed or when placed under bending, and they typically require encapsulation layers to protect the printed conductor. This paper presents a printable paste formulation and fabrication process based on screen printing for achieving a flexible and durable conductive polyester–cotton textile using an inexpensive carbon as the conductor. The process does not require an interface, the smoothing of the textile, or an encapsulation layer to protect the conductor on the textile. A resistivity of 4 × 10−2 Ω·m was achieved. The textile remains conductive after 20 standard washes, resulting in the conductor’s resistance increasing by 140%. The conductive textile demonstrated less than ±10% resistance variation after bending for 2000 cycles.

“…Spacer fabrics are 3D knitted fabrics known for their superior properties, such as good air and moisture permeabilities, cushioning performance, shock resistance, and pressure distribution, and ability to prevent ulcerations in clinical applications. [11][12][13] Their unique properties mean that spacer fabrics can be used for a wide range of products, for example, thermal insulated clothing, 14 mattresses, 15,16 protective clothing, 17 insoles 18,19 and wound dressings. 20 Nevertheless, there are also some limitations of spacer fabrics and concerns around their use in insole applications.…”

A novel spacer fabric with a weft-knitted structure of silicone tube and foam inlays is proposed for use in insoles to alleviate in-shoe pressure, reduce moisture and enhance thermal comfort. The material variables, including the diameter of the spacer yarn, type of inlaid material and net wrap and spacer pattern have been systematically investigated. Their force reduction and thermal characteristics in terms of air and water vapour permeabilities, thermal conductivity and impact force reduction are determined and compared to those of traditional insole materials. The results show that the inlays can effectively enhance the impact force reduction of the 3D spacer fabrics. In comparison to traditional insole materials, the proposed spacer fabric with an inlaid structure can enhance air and moisture permeabilities and heat dissipation to provide greater wear comfort for prolonged use. The air permeability, thermal conductivity and impact force reduction of the inlaid spacer structure can be modified with changes to the diameter of the spacer yarn, type of inlay and net material used and spacer pattern, whilst its water vapour permeability can also be varied by using different types of inlays. Spacer fabric with a higher number of spacer yarn courses and spacer yarn with a large diameter not only exhibits good impact force reduction with uniform thickness, but also offers good thermal conductivity. The findings of this study will contribute toward an insole design with the use of alternative insole materials for optimal foot protection.

“…Comfortable textile has attracted increasing attention to provide a microenvironment for the human body in humidity and temperature. − Clothing comfort, including thermal and wet comfort, plays a pivotal role in keeping normal human functioning, and any failure to maintain this significant performance would result in severe medical emergencies. Generally, a traditional fabric composed of natural fibers and synthetic fibers can rapidly absorb the moisture on humans and evaporate it subsequently .…”

Maintaining the human body’s comfort is a predominant requirement of functional textiles, but there are still considerable drawbacks to design an intelligent textile with proper moisture absorption and evaporation properties. Herein, we develop moisture-wicking and solar-heated coaxial fibers with a bark-like appearance for fabric comfort management. The cortex layer of coaxial fibers can absorb moisture via the synergistic effect of the hierarchical roughness and the hydrophilic polymeric matrix. The core layer containing zirconium carbide nanoparticles can assimilate energy from the body and sunlight, which raises the surface temperature of the material and accelerates moisture evaporation. The resulting coaxial fiber-based membrane exhibits an excellent droplet diffusion radius of 2.73 cm, an excellent wicking height of 6.97 cm, and a high surface temperature of 61.7 °C which is radiated by simulated sunlight. Moreover, the designed fabric also exhibits a significant UV protection factor of 2000. Overall, the successful synthesis of such fascinating fibrous membranes enables the rapid removal of sweat from the human body textile, providing a suitable and comfortable microenvironment for the human body.
