High strength industrial FDY monofilament

The main production processes of Polyester Monofilament Wire mainly include one-step production process and two-step production process. Among them, the use of high-speed spinning and high-speed drawing and twisting technology is a typical two-step process route, and it is the most used process route for the production of polyester monofilament. It is characterized by short technological process and high production efficiency. The spinning speed of high-speed spinning is 3000-600 m/min, and pre-oriented yarn (POY) can be obtained. At high winding speed, the fibers have a certain degree of orientation, and the structure is relatively stable. Drawing and twisting is an essential process in the production of polyester monofilament, which is called secondary molding. Stretching makes the structural unit of the fiber obtain a stable and stable orientation, so as to achieve the purpose of improving the physical and mechanical properties of the finished fiber.Textile Polyester Monofilament…
