At present, China's annual import of silk mesh has reached more than 1 million m, imported products are mainly more than 270 mesh polyester silk and nylon silk web. Technical content of high density screen, high strength and low extension screen, anti-static screen, calendering and other special processing screen and polyester mesh mesh are imported.

Domestic polyester yarns and Nylon yarns have a good market, and a small amount of polyester yarns are exported, but the types and specifications of domestic yarns are too few, and the high-quality, high-mesh and wide-width yarns need to be developed.

Foreign has developed a non woven new screen, this kind of screen to overcome the traditional silk screen warp and weft junction to paint sensitive tape to trouble. Modern advanced ultrafine graphics screen printing, fine level screen printing, high precision positioning screen printing, special ink quantitative screen printing and large color step screen printing, etc., have put forward higher requirements for the screen used: such as high strength, low elongation variability, repeatability, consistency, long service life, etc.; Such as printed electronic micro components, integrated circuits, multi-layer printed circuit, fluorescent digital display, space instrument flat panel display and other high-tech products; Such as some screen printing need antistatic, metallization treatment, physical, chemical treatment or special materials made of screen.

Recently, printed circuit boards and electronic components have become more precise, requiring a high degree of precision in size and location. Screen types in addition to the past polyester, polyamide, stainless steel, and the emergence of high tensile polyester yarn core, polyamide core set of mesh. Made of polypropylene ester fiber, mesh 330 mesh, line diameter longitude of 23μm, interweave 36μm, can obtain high tension, is really an epoch-making silk screen. And, in order to meet the requirements of precision, these screen after plasma treatment, metal evaporation, polishing processing and other processing.

Silk screen production, because of its high precision requirements, the vast majority of the past by foreign enterprises monopoly, such as Silk mart, Saifa, NBC and other well-known foreign companies. Now with the introduction of technology and equipment, domestic production of high-grade screen printing enterprises, such as Shanghai New iron chain Screen Mesh Co., LTD., Hebei Anping He Huang Net Industry Co., LTD. Domestic medium and low end screen screen production enterprises, such as Taizhou Best Net Industry Co., LTD., its price is relatively low, product quality is stable.
