The core process of chemical fiber production is spinning, the core of spinning is spinning machine, and the core of spinning assembly is spinneret (head). The spinneret, though only a part of the component, has become the core of the core spinning technology.

The spinning process of chemical fiber is different, and the spinneret (head) used is also different. Spinneret (head) although only a part, but it can be a longitudinal infinite improvement, horizontal infinite extension of the series of products. There are dry spinning, melting monomer spinning, and composite spinning. Such as polyester filament, short filament, nylon filament, acrylic filament, short filament, viscose fiber, acetate filament, etc. The rapid development of industrial textiles in recent years, especially the development of high-tech fibers such as spandex, carbon fiber, aramid fiber, polysulfide fiber and biomass fiber, has put forward higher requirements for the cooperation of spinnet.

Spinneret is the core technology products, the key point is that it in the process of the use of the key parts and role, lies in the geometric shape and machining precision need to be designed according to the requirements of the process.
