1. Silver fiber can be twisted with high elastic yarn, polyester staple fiber or cotton yarn into silver fiber conductive thread. The combination of these different materials can produce fabrics and fabrics with conductive and antistatic functions and sewing thread products，2. The conductive properties of the metallic elements gold, silver, copper, and iron are silver ranked second. Therefore, in addition to gold, the silver fiber conductive yarn has the best conductivity among the commonly used conductive fibers，3. Silver fiber and high elastic yarn can be twisted to form a good elastic conductive yarn, which is used in the knitting of touch screen gloves, radiation protection clothing, etc.4. The silver fiber conductive yarn used to make conductive or touch screen gloves can be tested with the simplest resistance meter, and the resistance is lower than the popular standard 10 to the 3rd power.5. The yarn made of silver-plated fiber is conductive enough to conduct current and ignite the LED bulb.
