Embodiment 1
[0024] Polyester polymer: Imported white polyester bottle flakes (clean flakes). Production of 3D black waterproof and oil-resistant polyester staple fiber.
[0025] (1) Dry the white polyester bottle flakes (ie polyester polymer) in a drum for 8 hours, feed 95% polyester polymer and 5% color masterbatch to the screw of the spinning production line by weight In the extruder, it is heated and melted to form a melt. The heating temperatures of the seven zones of the screw are: 275~285°C, 275~280°C, 280~285°C, 285~290°C, 285~290°C, 280~285°C ℃, 280~285℃.
[0026] (2) The melt flows out from the screw, passes through the pre-filter, is metered by the spinning pump, and is extruded through the spinneret hole at a pressure of 8.0 MP. Under the action of cold air, the melt is elongated, thinned, cooled and solidified to form nascent fibers. The speed at which the filaments are ejected from the spinneret hole is 1000m / min. The primary fiber silk is fed into the tow drum after roll...
Embodiment 2
[0041] Polyester polymer: Imported white polyester bottle flakes (clean flakes). Production of 3D red waterproof and oil-resistant polyester staple fiber.
[0042] (1) Dry the white polyester bottle flakes (ie polyester polymer) in a drum for 12 hours, feed 98% polyester polymer and 2% color masterbatch to the screw of the spinning production line by weight In the extruder, it is heated and melted to form a melt. The heating temperatures of the seven zones of the screw are: 275~285°C, 275~280°C, 280~285°C, 285~290°C, 285~290°C, 280~285°C ℃, 280~285℃.
[0043] (2) The melt flows out from the screw, passes through the pre-filter, is metered by the spinning pump, and is extruded through the spinneret hole at a pressure of 10.0 MP. Under the action of cold air, the melt is elongated, thinned, cooled and solidified to form nascent fibers. The speed at which the filaments are ejected from the spinneret hole is 1200m / min.
