摘　　要：为开发穿戴舒适、形式隐蔽、应用便捷的柔性电子标签,文章以70D/24F×3镀银导电纱为基材将标签天线绣制在纯棉机织物上,并与标签芯片封装制得刺绣型织物电子标签,进而研究各刺绣工艺参数对织物电子标签电阻和读取性能的影响。结果表明:针迹类型、针迹间距、针迹长度等刺绣工艺参数分别通过改变导电纱与电流传输方向夹角、导电纱密度及落针点数量,影响织物电子标签性能。标签天线的适宜刺绣工艺参数为针迹间距0. 25~0. 40 mm、针迹长度2. 0~4. 0 mm的直线针,尤其当采用针迹间距0. 35 mm、针迹长度2. 0 mm的直线针时,织物电子标签读取距离最远可达7. 6 m。In order to develop flexible RFID( Radio Frequency Identification) tags that are comfortable to wear,concealed in form and convenient to apply,70 D/24 F × 3 silver-plated conductive yarn was used as the base material to embroider the tag antenna on the pure cotton woven fabric. Subsequently,the tag antenna and the tag chip were packaged to obtain an embroidered fabric RFID tag,and then the effects of embroidery process parameters on the resistance and reading performance of the embroidered fabric RFID tag were studied. The results show that the embroidery process parameters such as stitch type,stitch spacing and stitch length affect the performance of the fabric RFID tag by changing the angle between the conductive yarn and the current transmission direction,the density of the conductive yarn and the number of needle drop points. The suitable embroidery process parameters for the tag antenna are as below: stitch spacing 0. 25-0. 40 mm and stitch length 2. 0-4. 0 mm. Especially when the stitch spacing is 0. 35 mm and the stitch length is 2. 0 mm,the reading distance of the fabric electronic tag is as far as 7. 6 m.
