Description

 Embroidery thread and manufacturing method thereof

 The invention relates to a embroidery thread and a preparation method thereof, in particular to an embroidery thread and a manufacturing method thereof. Background technique

 With the rapid development of society, the apparel industry has also developed into high-end products. The basis of high-end products is raw materials, new raw materials and new manufacturing methods are the basic guarantee for high-end products.

 The traditional gold and silver wire is divided into two types: flat wire and round wire. The gold foil is bonded to the paper and cut into a thin strip of about 0.5 mm to form a flat gold thread, and the flat gold wire and the cotton thread are processed into a round gold wire by a method such as bonding or core winding. Some of the most expensive traditional fabrics such as Yunjin still use the above-mentioned traditional filigree. The metal wire in the flat wire and the round wire is a thin and brittle skin, which is not washable, not wear-resistant, and is not resistant to cockroaches. It cannot be the durable goods that are really needed in life; and the workmanship is complicated, which is not conducive to mass consumption. Not conducive to mass production.

 The chemical fiber film gold and silver wire developed in the 1940s was made by sandwiching a layer of aluminum foil with two layers of butyl acetate film and cutting it into thin strips. The existing gold and silver wire imitation product is coated with a layer of aluminum on the polystyrene film substrate by vacuum coating technology, and then coated with a pigment layer and a protective layer, and cut into thin strips to form a gold and silver wire. However, the gold and silver wire is physically processed by vacuum plating aluminum or vacuum silver plating on a polyester film. And because the aluminum film in the gold and silver wire is not resistant to alkali; the silver film is not resistant to acid, the silver film will be blackened when it contacts the sulfide, and the stretching or heavy friction will cause the metal plating to peel off, so the chemical properties of the gold and silver wire are unstable. Can not be used like ordinary textile fibers. Summary of the invention

 In order to overcome the above-mentioned drawbacks of the prior art, one of the objects of the present invention is to provide an embroidery thread which is not afraid of water, is not afraid of washing, high temperature resistance, acid and alkali resistance, is not afraid of grinding, is not afraid of flaws, is flexible and smooth, and is expanded in use. The range can be woven, braided, hooked, and needle-punched by hand or embroidery. It can be widely used in various textiles and handicrafts required for life. It can become a durable product needed in real life, increase aesthetics and enhance value. And it can produce on a large scale, which is conducive to the consumption of the public.

 The embroidery thread is realized by the following technical solutions:
