“…This trend, is also observed in the theoretical curves with high correlation. The prediction domain extends from the elastic region to the plastic region, with a relatively high prediction error in the plastic region due to the friction of mono laments near the rupture point in consistence with an another work [44]. Regarding the impact of twist level on tensile behavior, it was found that higher twist levels (from 100/m to 300/m) correspond to lower stress tolerated by the multi lament yarn.…”

The number of fibers in the cross-section of a yarn determines its physical and mechanical properties. Among the parameters that affect fiber placement (packing) in the yarn core structure, the number of fibers, the number of twists, and variations in fiber length in various layers of yarn during the fabrication process are of prime importance. Theoretically, yarn formation is associated with two different packings: open-packing and close-packing with a single fiber in the core. The packing of fibers has been modeled using various approaches, including analytical, finite element, and experimental methods. In this study, an analytical approach combining theoretical methods and artificial neural networks (ANNs) is proposed to predict the tensile behavior of yarns with different numbers of fibers in the core regions (ranging from 2 to 5 fibers). The novelty of this method lies in its ability to predict the time-dependent stress-strain curve of multifilament yarns composed of monofilaments with circular cross-sections. The proposed method extends beyond the linear region, incorporating both structural and material properties. It leverages the strong mapping capabilities of ANNs rather than relying solely on elastic models. Validation of the method showed excellent agreement between experimental and theoretical values. Numerical simulation indicated results consistent with the theoretical ones, proving the model's precision in predicting the tensile behavior of multifilament yarns. This modeling procedure has the potential to revolutionize the approach to modeling textile structures.

“…The long length of filaments enables low twist levels to maintain the components together . Thus, theoretical studies have shown that the tensile strength of filament yarns was the maximum when they were untwisted and decreased with the twist level. − This behavior was experimentally shown by Yoshida et al using ramie-twisted yarns and by Dalfi et al, who demonstrated the maximum strength of S-glass yarns at a low twist level (30 twists per meter (tpm)). Discrepancies in this behavior have been observed in other studies, where the tensile strength of the yarns reached a maximum at higher twist levels.…”

Silk has recently attracted considerable interest owing to its versatile properties as a natural fiber, especially in the medical sector. However, the mechanical properties of silk limit its potential applications. In our earlier work, the mechanical performance of silk filaments was enhanced owing to the insertion of cellulose nanofibers (CNFs). Nevertheless, silk filaments must be assembled and twisted to form a continuous yarn. In this study, the mechanical properties of CNF-reinforced silk yarns were evaluated to determine the optimal yarn structure. The evolution of the Young's modulus, ultimate tensile strength, toughness, and elongation at break was assessed as a function of the twist level in comparison with regular silk. The results demonstrated that the most favorable compromise of the mechanical properties was obtained at 1000 twists per meter.

In this paper, a universal mechanical model for the torsional behavior of fiber bundle was established, grounded in the principles of spatial geometry and continuum mechanics, incorporating differential geometry formulas. The model was validated through self‐designed experimental equipment and finite element simulations using Ansys Workbench, showing strong agreement between predicted torsional fracture behavior and experimental results. The study further examined the contributions of fiber bending, torsion, and tension to the overall torque, revealing that torsion plays the dominant role. Additionally, the effect of filament count on the torsional performance of fiber bundles was analyzed, demonstrating that while the number of fibers significantly influences stress distribution, its impact on overall torque is minimal.Highlights A universal mechanical model for fiber bundle torsional is proposed. High consistency between simulation and experimental results. Examined filament count effect on torsional strength. More filaments reduce stress concentration, improving performance.
