In Guangdong and Fujian, the gold and silver silk is vividly called "scallions", that is, the condiments when cooking. It may be present, but not necessarily; if there is, the dishes will be more delicious; if not, the dishes can still be eaten. This fully illustrates the position of gold and silver silk in the textile industry. At present, it is mostly used in fashion, embroidery, gift packaging and other industries and the processing of knitting wool, yarn, knitted fabrics, warp knitted fabrics, woven fabrics, clothing accessories, decorative fabrics, sofas and other products. It is an ideal lining material.
All kinds of textiles can have reflective, flashing, fluorescent, luminous and other color effects after adding gold and silver filaments, which increase the aesthetics of clothing, greatly increase the added value of clothing, and meet the needs of most consumers. Due to the unstable chemical properties of the surface coating of gold and silver wire, it cannot be as acid and alkali resistant as ordinary fibers.
Gold and silver thread is a filament twisted by gold and silver silk + polyester or rayon. It is mainly used for computer embroidery and craft accessories. It is used in handicrafts, fashion, embroidery, gift packaging and other industries and knitting wool, yarn, knitted fabrics, warp knitted fabrics, etc. , Woven fabrics, clothing accessories, decorative cloth, sofa and other products processing, is an ideal lining material. The processed and woven fabrics and garments present a sense of elegance, nobility, and magnificence. However, because the gold and silver threads are processed by vacuum plating aluminum or vacuum silver plating on the polyester film by physical methods.
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 alkali resistant; the silver film is not acid resistant, and the silver film will turn black when contacted with sulfide. Stretching or heavy friction will cause the metal coating to peel off. Traditional gold and silver wires are divided into flat gold wires and round gold wires. Glue the gold foil to the paper and cut into thin strips of about 0.5 mm to form a flat gold thread, and then wrap the flat gold thread around cotton yarn or silk thread to form a round gold thread. Now some precious traditional fabrics such as Yunjin still use the above-mentioned traditional gold and silver silk.
The chemical fiber film gold and silver thread 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, there appeared polyester gold and silver threads made of polyester film through aluminum alloying and color coating. Polyester gold and silver thread includes two-color gold and silver thread, colorful gold and silver thread, rainbow thread, fluorescent thread and so on.
