Instrumental Observation and Testing: Lay the fabric flat and observe it under a microscope. If you see shiny lines, that's silver fiber. If all the lines are shiny silver fibers and arranged tightly and orderly, it's 100% silver fiber. 50% silver fiber consists of alternating silver fibers and ordinary fibers (without shine).
Touch and Feel Testing: Due to the special properties of silver, 100% silver fiber feels softer and more comfortable. In contrast, 50% silver fiber, containing ordinary fibers, feels slightly stiffer.
Color Observation and Testing: 100% silver fiber has a brighter and more lustrous color, while 50% silver fiber, due to the inclusion of ordinary fibers, appears grayish-white and lacks luster.
Shielding Testing: Fabric woven from 100% silver fiber has a stronger shielding effect and a denser density. 50% silver fiber, containing ordinary fibers, has a slightly weaker shielding effect.
Disassembly Testing: Cut a small piece of fabric and observe each line individually. 100% silver fiber fabric is woven from strands of pure silver fibers, giving it a shimmering metallic sheen. 50% silver fiber fabric, on the other hand, is woven from one pure silver fiber and one ordinary fiber, resulting in a noticeable difference in appearance.
