Because it is mainly composed of gold and silver, it is named. "Thread" is a conventional name, but it is actually a piece of silk. In ancient times, gold and silver thread was made into thin foil by hand, mounted on thin sheepskin or paper, and then cut into filaments, which was called "flat gold and silver thread".

Metal is a kind of wire fabric. Generally, cotton and polyester or nylon account for more than 90%, and the rest are metal wires, not necessarily precious metals. Metal wire fabric is a kind of high-grade fabric formed by embedding metal fibers into clothing through high-tech drawing. In the whole fabric, metal wire accounts for about 3%~8%. Generally speaking, at the same technical level, the higher the proportion of metal wire, the more expensive it is. Due to the implantation of metal wires, the overall color of the fabric is bright and bright, with metallic luster, which can reflect the unique luster of metal. However, it should be noted that the characteristics of wire fabrics are not only in metallic luster, but also have anti-static and anti-radiation functions.
