为了改善金属裸丝在可穿戴设备电路中应用的不足,利用多功能细纱机纺制不锈钢丝包芯纱。以3股单根直径为0.02 mm的超细不锈钢丝为芯丝,棉短纤作为鞘层制备包芯纱,并进一步制备针织物电路,对包芯纱及针织物电路的力学及电学性能等进行测试。结果表明:不锈钢丝包芯纱断裂强度接近不锈钢裸丝,且包芯纱芯丝具有与不锈钢裸丝相近的电学性能;不锈钢丝包芯纱具有较好的编织性能,可用于针织物电路的制备;由于弹性纱的引入及针织物特殊的线圈结构,织物电路具有较好的弹性回复性;不锈钢丝包芯纱制备的织物电路在单向拉伸时具有优异的导电稳定性;织物电路可用于传感器的连接并传输信号。 相似文献

研究导电丝嵌织型织物防静电性能的影响因素。分析了有机导电纤维种类、导电丝基材、导电纱的成纱结构、导电纱与织物的结合方式、织物组织结构、织物单位面积质量及厚度这几方面对织物防静电性能的影响。实践经验表明:有机导电纤维种类和导电丝基材对有机导电纤维导电性有显著影响;导电纱成纱结构和与织物的结合方式以及织物组织、单位面积质量和厚度都对织物防静电性具有较显著影响。认为在具体生产中必须综合考虑以上各因素,并结合防静电织物后道加工、使用及交货要求进行防静电织物的设计生产。 相似文献

防静电织物相关服用性能的测试分析 总被引:1,自引:1,他引:0
研究嵌织导电丝类防静电织物的服用舒适性和外观性能.测试了4种防静电织物的表面电荷密度、透湿量、芯吸高度、透气率、折皱回复角、抗起毛起球性和悬垂系数,并运用织物结构理论分析了导电丝对嵌织导电丝类防静电织物相关服用性能的影响.研究表明:导电丝含量的增加大大降低了织物的透湿性;导电丝的分布状况对织物的芯吸能力有明显影响;但导电丝的配置有利于增强织物的折皱回复性能.通过对主体原料的合理选择及织物结构的合理设计,在不增加导电丝含量的前提下可以使织物既具有优良的防静电性能又能获得较好的服用性能. 相似文献

PTT混纤针织物风格的主观评价 总被引:1,自引:0,他引:1
采用分级评定法对PTT短纤、长丝、PTT/PET的复合丝与常规纤维混纺交织研制的31种针织面料进行了主观评价打分,然后对这些试样的评价值的平均值及标准偏差分别进行了比较.结果表明,在锦纶长丝与PTT长丝交织成的长丝针织物中使用0.11 tex的锦纶能够改善织物的手感;在PTT/PET并列复合丝与细旦涤纶交织制成的针织物中使用0.22~0.33 tex的并列复合丝虽然可提高弹性,但会降低手感,在产品设计时应考虑将其他手感优良的纤维覆盖在织物表面;加入适当细度及含量的涤纶纤维可降低织物成本,提高产品的尺寸稳定性. 相似文献

探讨镀银纤维含量及其在织物中的分布对织物静电性能的影响。通过测试和分析不同镀银纤维含量和分布的平纹织物电荷面密度,结果表明:随着镀银纤维含量的增加电荷面密度减小,但其变化趋势会受到间隔嵌织非功能性纱线的影响;非功能性纱线的织入会在织物中形成静电积聚区,织物的静电性能取决于静电积聚区的大小和功能纱线的防静电性能;非功能纱线的织入会恶化由于镀银纤维在纱线中分布的不均匀性造成的织物静电性能的不均匀性;与赛络菲尔纱织物和长丝交织织物相比,短纤混纺织物具有更好的防静电效果。 相似文献

This article presents a new computer geometric modelling approach for three-dimensional of two-ply yarn structures with filament assembly model. The geometric of individual filaments in two-ply yarn structures with uncompressed and compressed states were studied. In the uncompressed state the filaments in ply yarns have the form of coaxial double wound helices; we simulate the paths of these filaments in the ply yarns. In the compressed state the transformation of the initial filament distribution from the uncompressed state into the distribution after compression by a transverse force. The ply yarns cross-section uses the concept of virtual locations to simulate the filament distributions. Each cross-section is rotated along the single yarn and the ply yarn length. The curve of each filament in each two successive cross-sections is approximated by NURBS and then each curve is created by sweeping a closed curve along the centerline of the single yarn and ply yarn path. The method described is demonstrated in the uncompressed and compressed state of two-ply yarns by the CAD model using geometric parameters of the double-rove acrylic-fiber yarns. The simulation using this approach can demonstrate more realistic and improved visual simulations of real two-ply yarns. 相似文献

本文旨在通过两种加工方式研制成抗电磁辐射精纺面料,一种是镀银长丝与羊毛单纱并捻合股织造成并捻织物,一种是镀银长丝直接用作经纬纱与羊毛交织成交织物。由织物的屏蔽效能测试结果可知,并捻织物电磁屏蔽效能在2250-2650MHz波段内优于交织物,最高可达85dB,具有较好的抗电磁辐射效果。另外,经纬密度的变化对织物电磁屏蔽能力也有一定影响,两种织物紧度在78%左右、交织物羊毛与长丝比例为1:2时电磁屏蔽效果较好。其结果对开发高性能抗电磁辐射精纺面料有一定的指导意义。 相似文献

This paper presents a new computer geometric modeling approach for three-dimensional woven fabric structures. Pierce’s geometry of the weave fabric of yarn from an arc abscissa (Peirce’s) model is presented. Then, new algorithms with a filament assembly model for a single yarn composed of many filaments by twisting along the crimp shape in the warp/weft is developed. The concept of a virtual location is used to simulate the fiber distributions in the yarn cross-section. Each cross-section is rotated along the yarn length by a pre-determined amount to allow for the yarn twist. The curve of each filament in each two successive cross-sections is approximated by NURBS and then each curve is created by sweeping a closed curve along the centerline of the yarn path. The method described is demonstrated by the CAD model of woven fabrics with plain and twill weaves. The simulated woven fabrics using this approach can demonstrate a wider variety and improved visual simulations of real woven fabric and can then be further generalized for different and more complicated fabrics. The method is necessary as an input to many computational models, such as modeling the mechanical properties or the heat transfer of fabrics or composite parts. 相似文献
