What is the difference between gold and silver wire and gold and silver wire?

The gold and silver wire is to use the physical method to cut the colored PET polyester film into very thin wires! The surface layer is plated with aluminum or silver by electroplating of polyester or nylon film, and then cut and processed into wires of different widths as required.

In Guangdong and Fujian, the gold and silver threads are vividly called "scallions", that is, a condiment when cooking. This fully illustrates the position of gold and silver wire in the textile industry. At present, it is widely used in fashion, embroidery, gift packaging and other industries and the processing of woven wool, yarn, knitted fabrics, warp knitted fabrics, woven fabrics, clothing accessories, decorative fabrics, sofas and other products. It is an ideal lining material.

The addition of gold and silver threads to various textiles can make the products have color effects such as reflection, flash, fluorescence, luminous, etc., which increases the beauty of clothing, greatly improves the added value of clothing, and meets the needs of most consumers. Due to the unstable chemical properties of the surface coating of gold and silver wires, it cannot be as resistant to acid and alkali as ordinary fibers.

Gold and silver thread is a filament twisted from gold and silver thread + polyester or rayon, mainly used in computerized embroidery and craft accessories, used in handicrafts, fashion, embroidery, gift packaging and other industries and woven wool, yarn, knitted fabrics, warp knitted fabrics , woven fabrics, clothing accessories, decorative cloth, sofa and other products processing, is an ideal lining material. The processed and woven fabrics and costumes are elegant, generous and gorgeous. However, because the gold and silver wires are processed by vacuum plating aluminum or vacuum silver plating on the polyester film by physical methods, and then coloring and processing.

Therefore, the chemical properties of gold and silver threads are unstable and cannot be used like ordinary textile fibers. The aluminum film in the gold and silver wire is not resistant to alkali; the silver film is not resistant to acid, and the silver film will turn black when it contacts with sulfide, and the metal coating will peel off after stretching or heavy friction. Traditional gold and silver wire is divided into two types: flat gold wire and round gold wire. The gold foil is glued to the paper and cut into thin strips of about 0.5 mm to form a flat gold wire, and then the flat gold wire is wrapped around cotton yarn or silk thread to form a round gold wire. Now some precious traditional fabrics such as Yunjin still use the above-mentioned traditional gold and silver wires.

The chemical fiber film gold and silver wire developed in the 1940s is made of two layers of butyl acetate cellulose film sandwiched with a layer of aluminum foil and then cut into thin strips. Later, polyester gold and silver threads made of polyester film through aluminum and color coatings appeared. Polyester gold and silver threads include two-color gold and silver threads, multicolored gold and silver threads, rainbow threads, fluorescent threads, etc.
