There are many kinds of polyester monofilament, including flame retardant monofilament, triangular shaped monofilament, flat monofilament, high shrinkage monofilament, hollow monofilament, cationic monofilament, full extinction monofilament, anti-UV monofilament PET monofilament nylon monofilament Wait.
The main production process of polyester monofilament mainly includes one-step production process and two-step production process. Among them, high-speed spinning and high-speed drawing and twisting technology are typical two-step process routes, which are the most popular process routes for producing polyester monofilament. It is characterized by short process flow and high production efficiency. The spinning speed of high-speed spinning is 3,000 to 600 m/min, and pre-oriented yarn (POY) can be obtained. At high winding speeds, the fibers have a certain degree of orientation and the structure is relatively stable. Stretching and twisting is an indispensable process in the production of polyester monofilament, which is called overmolding. Stretching results in a stable and stable orientation of the structural units of the fiber, thereby achieving the objective of improving the physical and mechanical properties of the finished fiber.
One-step production of polyester monofilament technology uses 8, 10 or 12-hole spinneret, and completes the spinning process, virgin fiber draft orientation, fiber heat setting and winding process on the same machine. The silk is obtained on the silk cake. The wound monofilament cake is then subjected to fiber division by a yarn splitter to obtain a polyester monofilament fiber.
