摘要(Abstract):

智能可穿戴设备中柔性传感器和导电纱线成本高、导电性差以及亲肤性差的缺点阻碍了智能可穿戴设备在柔性电子器件的广泛应用。为解决以上问题,首先通过环锭细纱机制备外层包覆棉纤维的棉/导电尼龙包芯纱,随后通过二维编织工艺将制备的棉/导电尼龙包芯纱包覆在氨纶单丝表面,成功制备出一种棉/导电尼龙大应变包覆纱,并测试分析了棉/导电尼龙包芯纱与棉/导电尼龙大应变包覆纱的结构与性能。结果表明:该方法制备的棉/导电尼龙大应变包覆纱的应变能力可以达到230%,拉伸强度为500 MPa,并呈现出优异的电阻稳定性能与高灵敏性,可广泛用于人体运动监测领域。
The disadvantages of high cost, poor electrical conductivity and skin affinity of flexible sensors and conductive yarns in smart wearable devices hinder the wide application of smart wearable devices in flexible electronic devices. In order to solve the above problems, the cotton/conductive nylon core-spun yarns covered with cotton fibers by ring-spinning frame was firstly prepared, and then the prepared cotton/conductive nylon core-spun yarns was covered on the surface of spandex monofilaments by two-dimensional weaving process, thus a large strain cotton/conductive nylon covered yarns was successfully prepared.The structure and properties of cotton/conductive nylon core-spun yarn and cotton/conductive nylon highstrain covered yarn were tested and analyzed. The results show that the cotton/conductive nylon high-strain covered yarn prepared by this method has a strain capacity of 230%, tensile strength of 500 MPa, excellent resistance stability and high sensitivity, and can be widely used in the field of human motion monitoring.
