The first silver fiber production technique was to coat a silver layer on the surface of the fiber by plating. However, the technology is immature, the product adhesion uniformity is low, the silver layer is easy to fall off, and the silver layer is not resistant to washing, so that the performance is unstable. With the development of science and technology, a high-tech metallized fiber, namely a silver fiber, is developed, wherein the high-tech metallized fiber is obtained by sufficiently combining a pure silver permanent seed crystal on a nylon 6/nylon 66 fiber through a penetration and solidification seed crystal technology. The structure not only keeps the original textile properties of the silver fiber, but also endows all the functions of the silver fiber, such as good conductivity, antistatic property, physical antibiosis, electromagnetic radiation resistance, constant temperature and the like of the silver fiber.
