“…Incorporated micro-and nano-particle-sized far-infrared (FIR) accumulating minerals (magnesium, zirconium and iron oxides, silicon carbide and germanium compounds, etc.) exhibit the ability of the human body to accumulate/release heat [65][66][67][68][69]. The most important part of creating a human sense of heat is the far-infrared spectrum of IR radiation, namely electromagnetic waves of 6-15 mm long, because only waves of that length of FIR radiation emitted by heat can be received and delivered to the human body [67,70].…”

The use of a new generation chemical fibers with various functional additives offers new possibilities for the development of advanced (multi)functional textile products. Such compounds as phase change materials (PCMs), metals (like cooper, silver), also natural or chemical insect repellents, FIR emitting ceramic particles and etc. incorporated into fibres’ structure are essential for development of knitted fabrics directly contacting to the skin with effective thermoregulation and such protective properties as: antimicrobial, antistatic, repellence against blood sucking insects. The main parts of socks investigated were knitted in plain plated single jersey pattern. The 3-ply twisted yarns of new structures were used in the outer layer of socks. Yarns were made by using single yarns with PCMs, insect repellent permethrin, ceramic and silver additives containing fibres (Cell Solution® Clima, Cell Solution® Protection, Resistex® Silver). The inner layer of socks was made of polyester (PES) 3-ply twisted yarns with different number of filaments resulted in different structures of socks’ fabric. Based on all obtained thermoregulating and protective characteristics of investigated different knitted fabric structures of socks, the optimal knitted socks were selected. The obtained results of investigations are significant for the development of other knitted fabrics worn next to the skin.

“…Ceramic particles would be a great choice in order to improve the functionality as well as the chemical and mechanical resistance of the PU coatings. Ceramic particles, such as aluminum oxide, silicon dioxide, titanium dioxide, were studied for their unique property to constantly emit FIR rays [ 14 ]. The application of aluminum oxide could significantly increase the surface emissivity of coated composite material [ 15 , 16 ].…”

The far-infrared ray (FIR) is one kind of electromagnetic wave employed for numerous bio-interactive applications such as body thermoregulation, infrared therapy, etc. Tuning the FIR-emitting property of the functional textile surface can initiate a new horizon to utilize this property in sportswear or even smart textiles. Ceramic particles were studied for their unique ability to constantly emit FIR rays. The purpose of this research is to characterize the FIR emission properties and the thermogravimetric analysis of ceramic-embedded polyurethane films. For this purpose, ceramic particles such as aluminum oxide, silicon dioxide, and titanium dioxide were incorporated (individually) with water-based polyurethane (WPU) binder by a sonication technique to make a thin layer of film. Significant improvement in FIR emissive property of the films was found when using different ceramic particles into the polyurethane films. Reflection and transmission at the FIR range were measured with a gold integrating sphere by Fourier-transform infrared (FTIR) spectrometer. The samples were also characterized by thermogravimetric analysis (TGA). Different physical tests, such as tensile strength and contact angle measurements, were performed to illustrate the mechanical properties of the films. The study suggested that the mechanical properties of the polyurethane films were significantly influenced by the addition of ceramic particles.

By continuously enhancing the blood flow, far-infrared (FIR) textile is anticipated to be a potential non-pharmacological therapy in patients with peripheral vascular disorders, for instance, patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) and experiencing vasculogenic erectile dysfunction (VED). Hence, we manufactured a novel polymer composite, namely, germanium-titanium-π (Ge-Ti-π) textile and aimed to evaluate its characteristics and quality. We also investigated the immediate and long-term effects of the textile on patients with ESRD undergoing HD and experiencing VED. The Ge-Ti-π textile was found to have 0.93 FIR emissivity, 3.05 g/d strength, and 18.98% elongation. The results also showed a 51.6% bacteria reduction and negative fungal growth. On application in patients receiving HD, the Ge-Ti-π textile significantly reduced the limb numbness/pain (p < 0.001) and pain score on the visual analog scale (p < 0.001). Moreover, the Doppler ultrasound assessment data indicated a significant enhancement of blood flow in the right hand after 1 week of Ge-Ti-π textile treatment (p < 0.041). In VED patients, the Ge-Ti-π underpants treatment significantly improved the quality of sexual function and increased the average penile blood flow velocity after 3 months of the treatment. Our study suggests that the Ge-Ti-π textile could be beneficial for patients with blood circulation disorders.
