The production process of Polyester staple fiber equipment is a complex and delicate process, involving multiple key steps and links. The following is a detailed explanation of the process flow:
First of all, the raw material of polyester staple fiber is polyester slices, and slice preparation is the first step in the entire production process. Slice preparation is to process polyester raw materials into slices with certain specifications and quality through processes such as melting, extrusion, stretching, and cutting. This step is crucial to the selection and processing of raw materials, as it is directly related to the stability of subsequent production and product quality.
Next, the slices enter the dry spinning stage. In this step, the slices are put into the melt viscosity control device. After being heated and melted, the melt is injected into the nozzle from the spinning hole through filtration, pressurization, extrusion and other processes. The melt is then drawn into fibers by a high-speed air stream. During this process, parameters such as temperature, pressure, and air flow speed need to be precisely controlled to ensure the quality and performance of the fiber.
In addition to dry spinning, liquid spinning is also an important method in the production of polyester staple fiber. In the liquid spinning process, the slices are mixed with a mixed solvent, and in a high-speed rotating centrifuge, the solvent is separated by centrifugal force, leaving the wet fiber. The wet fibers are then dried by hot air drying to obtain polyester staple fibers.
Fiber drawing is another key link. During the stretching process, the collected wet fibers are stretched in a direction to increase the strength of the fibers and the uniformity of the cross-sectional shape. Control of drawing ratio and speed has an important impact on the mechanical properties of the fiber.
Finally, a cutting step cuts the drawn fiber into the desired length. The choice of cut-off length depends on the application area and customer requirements. After cutting, the fibers are heat-set to further improve their stability and durability.
During the entire production process, Polyester staple fiber equipment plays a vital role. It can not only accurately control various process parameters, but also achieve automated and continuous production, improving production efficiency and product quality.
To sum up, the production process of Polyester staple fiber equipment is a complex and delicate process, which requires strict control of various links and parameters to ensure the quality and performance of the final product.
