“…The formation of the CB conductive network results in strong interactions between the CB particles, and thus, the morphologies of the CB/composites are fixed by this network structure. However, this effect is less prominent when it occurs at a CB content above the percolation threshold [34,35]. As shown in Figure 5b, the annealed CB10/PAN, ABCB12/PAN, BZCB12/PAN, and Ag-ABCB20/PAN fibers exhibit maximum electrical conductivity values of 3.4 × 10 −6 , 7.6 × 10 −6 , 8.9 × 10 −4 , and 1.8 × 10 −6 S/cm, respectively.…”

Composites of carbon black (CB) and polymers are attractive for producing conductive fibers. Herein, to achieve improved interactions with polymers, the surface of CB was modified to form 4-aminobenzoyl-functionalized carbon black (ABCB), benzoxazine-functionalized carbon black (BZCB), and Ag-anchored carbon black (Ag-ABCB). The surface-modified CBs were characterized by Fourier transform infrared spectroscopy and thermogravimetric analysis, and X-ray photoelectron spectroscopy was utilized to confirm the presence of Ag in Ag-ABCB. Conductive polyacrylonitrile (PAN) fibers were wet-spun with conductive fillers (CB, ABCB, Ag-ABCB, and BZCB) to investigate the effects of various functional groups on the electrical and mechanical properties. After annealing the conductive PAN fibers, the conductivity and tensile strength greatly increased, whereas the diameter decreased. Notably, the fiber with a BZCB/PAN weight ratio of 12/88 possessed a conductivity of 8.9 × 10−4 S/cm, and strength of 110.4 MPa, and thus the highest conductivity and best mechanical properties in the conductive PAN fiber. These results indicate that the annealed BZCB/PAN fibers have potential applications in the manufacturing of antistatic fabrics.

There has been a steady progress in developing synthetic fibers in the past few years. Bicomponent fibers and nanofibers in a core/shell (C/S) configuration, including two dissimilar materials have presented unusual potential for use in many novel applications. These fibers can be produced using a variety of materials via different techniques i.e., coaxial melt spinning and electrospinning. In this review, we discuss the recent advances in C/S fibers and nanofibers' production. The first part has been assigned to the bicomponent fibers manufacturing technology, while production and applications of C/S nanofibers have been described in the second part.

“…Other methods of incorporation have been used by Lu et al [71], through the functionalization of a non-woven fabric with a side-by-side fiber configuration combining the wet paper manufacturing method and the thermal bonding process. ZnO like other semiconductor oxides (TiO2, SiO 2 and Al 2 O 3 ) is used as a UV shield [72] and other antibacterial applications that grant this type of nanoparticles including silver and copper; it comprises the Rayleigh dispersion, specifically between 200 to 400 nm [73].…”

Based on the results of research papers reflected in the scientific literature, the main examples, methods and perspectives for the development of technical textiles are considered. The focus of this work is to concentrate the results obtained for different textile applications (technical textiles) through the use of biodegradable polymers modified and improved with nanoparticles. The techniques for obtaining polymeric nanocomposites, finishing processes, type and structure of textiles are specified. In general, key aspects are identified for a better understanding of the technical challenges and physicochemical effects of the fibers.
