“…The PAN/TiO 2 nanofiber yarn with 0.5 wt% TiO 2 nanoparticles, 1500 TPM twist, and 50% hot‐stretching, had a higher equilibrium height of the water, which was 10 mm. [ 14 ] From the viewpoint of twist effect on the wicking ability, the same conclusion has been found in the study of Musavijad et al and Hajiani et al [ 15, 16 ] Liu et al used a different covering method to produce a continuous nanofiber core‐spun yarn and obtained more aligned nanofibers deposited on the surface of core yarn. The results showed that the wicking property of this yarn deteriorated with an increase in the rotation speed of the disk due to an increase in the alignment degree between the direction of nanofibers and the core yarn.…”

One critical property of a nanofibrous structure is the wicking behavior in contact with liquids. This work's purpose is fabrication and investigation of tensile and wicking properties of a newly designed three‐layer nanofibrous yarn consisting of polyamide 6/poly(L‐lactic acid) (PA/PLLA) with a similar idea to Bobtex spun yarn structure in which adhesion between core (PA) and sheath (PLLA) is provided with a thin layer of polymeric thin film. The tensile strength and strain decreased 32 and 46%, respectively, in a three‐layer yarn compared with two‐layer, that is, yarn without the adhesion film. In addition, the ultimate strength of the three‐layer yarn was higher than a PLLA yarn. The vertical wicking test for three‐layer nanofibrous yarn reveals that at short times, capillary rise kinetics follow the Lucas–Washburn law while increasing the take‐up velocity of the take‐up roller in yarn fabrication leads to increasing the maximum height of water in yarn.

“…Here, the height of wicking was about 12.17 mm in S4 sample, which was more than reported by Abbaszadeh et al (3 mm) and Ravandi et al (10 mm). [ 13,14 ] As well it was less than the maximum height of wicking in the work of Liu et al and Jin et al, which was reported 76 and 20 mm, respectively. [ 17, 18 ]…”

“…Another reason could be that when nanoparticles are used in fibers, they can increase water penetration and eventually lead to more hydrophilicity due to the fibers’ wick properties. [ 49 ] Asempour et al. [ 46 ] reported that the modification of HNT with an amine‐terminated dendrimer lowers the WCA of polysulfone ultrafiltration membrane nanocomposite.…”

The main challenge in treating injuries is excessive bleeding whereas intervention is required if the body's hemostatic systems fail to control the bleeding. Herein, a novel nanocomposite consisting of poly(lactic acid) (PLA) and poly(amidoamine) (PAMAM) dendrimer functionalized halloysite nanotube (HNT) with a highly porous structure via electrospinning is developed. HNT is functionalized by PAMAM via divergent synthetic routes from zero to third‐generation numbers. The effect of different percentages and generation numbers of PAMAM dendrimer (G1, G2, and G3) functionalized HNT on PLA is studied using physicochemical nanocomposite characteristics. These resultant nanocomposites provide a nanofibrous structure with appropriate physicochemical characteristics such as mechanical properties, surface wettability, and water permeability. The hemostatic assays indicate that nanocomposite with PAMAM G3 functionalized HNT have the quickest blood clotting time due to the abundant amino functional group. Furthermore, the nanocomposites with 10 wt% of nanoparticles significantly promote cellular behavior in vitro. The in vivo study demonstrates that PLA/PAMAM G3 functionalized HNT promotes angiogenesis, collagen deposition, and re‐epithelialization in the wound sites of the rat model, as well as inhibiting inflammatory response. The findings indicate that nanofibrous structure and the presence of dendrimer functionalized HNT have a synergetic effect on the enhanced nanocomposite wound healing performance.

The rapid advancement in nanofiber technologies has revolutionized the domain of yarn materials, marking a significant leap in textile technology. This review dissects the nexus between cutting-edge nanofiber technologies and yarn manufacturing, aiming to illuminate the pathway toward engineering advanced textiles with unparalleled functionality. It first discusses the fundamentals of nanofiber assemblies and spinning techniques, primarily focusing on electrospinning, centrifugal spinning, and blow spinning. Additionally, the study delves into integrating nanofiber spinning technologies with traditional and modern yarn fabrication principles, elucidating the design principles that underlie the creation of yarns incorporating nanofibers. Twisting technologies are explored to examine how they can be optimized and adapted for incorporating nanofibers, thus enabling the production of innovative nanofiber-based yarns. Special attention is given to scalable strategies like centrifugal and blow spinning, which are spotlighted for their efficiency and scalability in fabricating nanofiber yarns. This review further analyses recently developed nanofiber yarn applications, including wearable sensors, biomedical devices, moisture management textiles, and energy harvesting and storage devices. We finally present a forward-looking perspective to address unresolved issues in nanofiber-based yarn technologies.
