This research investigated the use of electrospun nanofibers as reinforcing laminates in textiles to enhance their mechanical properties for use as smart and technical textile applications. Crimping plays a crucial role in textiles. Because of crimp, fabrics have extensibility, compressibility, and improved quality. Although crimping is inevitable for fabrics used in smart textiles, it is also a disadvantage as it could weaken the fibers and reduce their strength and efficiency. The study focused on preparing laminated textile composites by electrospinning a polyacrylonitrile (PAN) polymer onto textile fabric. The research examined the effect of electrospun nanofibers on the fabric by using a tensile testing machine and scanning electron microscopy. The results revealed that the prepared laminated textile was crimp-free because of the orientation of the nanofibers directly electrospun on the fabric, which exhibited perfect bonding between the laminates. Additionally, the nanofiber-reinforced composite fabrics demonstrated a 75.5% increase in the elastic moduli and a 20% increase in elongation at breaking. The study concluded that the use of electrospun nanofibers as laminates in textile composites could enhance the elastic properties, and prepared laminated composites will have the advantages of nanofibers, such as crimp-free elastic regions. Furthermore, the mechanical properties of the laminated textile composite were compared with those of the micromechanical models, providing a deeper understanding of the behavior of these laminated composites.
本研究探讨了将电纺纳米纤维用作纺织品中的增强层压板，以提高其机械性能，用于智能和技术纺织品应用。卷曲在纺织品中起着至关重要的作用。由于卷曲，织物具有可拉伸性、可压缩性和更高的品质。尽管卷曲对于智能纺织品中使用的织物来说是不可避免的，但它也是一个缺点，因为它可能会削弱纤维并降低其强度和效率。该研究重点是通过将聚丙烯腈（PAN）聚合物静电纺丝到织物上来制备层压纺织复合材料。该研究使用拉伸试验机和扫描电子显微镜检查了电纺纳米纤维对织物的影响。结果表明，由于纳米纤维直接静电纺丝在织物上的取向，制备的层压织物无卷曲，层压板之间表现出完美的结合。此外，纳米纤维增强复合织物的弹性模量提高了75.5%，断裂伸长率提高了20%。该研究得出结论，在纺织复合材料中使用电纺纳米纤维作为层压板可以提高弹性性能，制备的层压复合材料将具有纳米纤维的优点，如无卷曲弹性区域。此外，将层压纺织复合材料的机械性能与微机械模型的性能进行了比较，从而更深入地了解这些层压复合材料的行为。
