Abstract

In this study, stainless steel (SS) filaments are wrapped in Ge fibers to form core-spun yarns. The yarns along with 500 D polyester (PET) fibers undergo weaving, thereby forming functional woven fabrics. The experiment is composed of two parts:yarns and fabrics. The yarns are twisted with TPI of 8, 9, 10, 11, and 12, and then tested for tensile strength and tensile elongation. The yarns possess mechanical properties that are dependent on the TPI-the higher the TPI, the better the mechanical properties. The maximal mechanical properties occur when the core-spun yarns are made of 12 TPI where the maximal tensile strength is 5.26 N and the lowest elongation is 43.2%. As for the functional woven fabrics, they are made of Ge/SS core-spun yarns as the weft yarns and 500 D PET yarns as the warp yarns. The tensile strength, tensile elongation, negative ion release, electromagnetic interference shielding effectiveness (EMI SE), and air permeability tests are conducted, determining the optimal woven fabrics. The 12 TPI core-spun yarns provide the woven fabrics with the maximal tensile strength of 153.6 N and the optimal elongation at break of 10.08%. In addition, the woven fabrics made with 8 or 9 TPI core-spun yarns exhibit an optimal EMI SE of 41 dB, an optimal air permeability of 212 cm/cm/s, and an optimal release amount of negative ion of 550-600 ions/cc. The proposed woven fabrics have a broad range of applications, such as functional garments and bedding.

摘要

在本研究中，不锈钢（SS）长丝被包裹在锗纤维中以形成包芯纱。这些纱线与500 D聚酯（PET）纤维一起进行织造，从而形成功能性机织物。实验由两部分组成：纱线和织物。纱线的捻度为8、9、10、11和12 TPI，然后测试其拉伸强度和拉伸伸长率。纱线的机械性能取决于捻度——捻度越高，机械性能越好。当包芯纱的捻度为12 TPI时，机械性能达到最大值，此时最大拉伸强度为5.26 N，最小伸长率为43.2%。至于功能性机织物，它们由锗/不锈钢包芯纱作为纬纱和500 D PET纱作为经纱制成。进行了拉伸强度、拉伸伸长率、负离子释放量、电磁干扰屏蔽效能（EMI SE）和透气率测试，以确定最佳的机织物。12 TPI的包芯纱为机织物提供了153.6 N的最大拉伸强度和10.08%的最佳断裂伸长率。此外，由8或9 TPI包芯纱制成的机织物具有41 dB的最佳EMI SE、212 cm/cm/s的最佳透气率和550 - 600离子/立方厘米的最佳负离子释放量。所提出的机织物具有广泛的应用，如功能性服装和床上用品。
