Embodiment 1
[0044] Manufacture of colorful fancy polyester yarn prepared by changing the traverse cylinder, such as figure 2 with 3 Shown:
[0045] Conventional 150D / 36F raw yarn POY comes out from the outlet 1 of the horizontal guide tube, and is colored at 4 points of the injection coloring device, and then fed into a roller 10, and then cooled after being heat-set in a hot box 11, and passed through a fake After the twist deformation process, it enters the second heating box for secondary heat setting, and all the other silk paths are the same as the prior art products. The air pressure line of the traverse cylinder-traversing injection type shader plunger 2 is connected with the air pressure line of the solenoid valve 8, and the air pressure path of the solenoid valve is controlled by the programmable logic controller (PLC) 9 program at predetermined intervals. Off, the on-off of the air pressure in the traversing cylinder drives the plunger 3 in the tube of the traversing injectio...
Embodiment 2
[0047] The raw material yarn is 150D / 144F "Z" special-shaped cross-section bright far-infrared pre-oriented yarn POY and 75D / 144F groove-shaped special-shaped bright light and anti-ultraviolet POY mixed fiber composite; composite ratio: 1:1.
[0048] Manufacture of 150D / 144F "Z" special-shaped cross-section bright and far-infrared POY: use large bright polyester polyester chips in POY spinning equipment, use "Z" special-shaped spinneret to spin, use masterbatch injection machine to add far infrared Infrared functional polyester masterbatch, the addition of masterbatch is 6%, the spinning temperature is 283°C, and the spinning temperature is 283°C to produce "Z" special-shaped cross-section bright far-infrared POY with a silk speed of 2800m / min and a POY elongation of 136%.
[0049] Manufacturing of 75D / 144F grooved special-shaped bright and anti-ultraviolet POY: during the spinning process of bright polyester chips on POY equipment, a grooved spinneret is used, and an injection...
Embodiment 3
[0052] Manufacture of colorful fancy polyester yarn prepared by changing the traverse cylinder: such as figure 2 with image 3 Shown:
[0053] Four conventional 250D / 384F raw yarns POY come out from the exit 1 of the horizontal guide tube after two pairs of joint strands, and the joint strands are respectively passed through the horizontal injection type yarn feeder 4 for coloring, and then fed to a roller 10, and then enter a hot box 11 , while being processed, the dyed part of the silk strip is heat-set once, enters the second heat box after cooling, is heat-set twice, and all the other silk paths are the same as the prior art product. Traversing Cylinder - The air pressure line of the traverse cylinder 2 of the traversing injection shader is connected to the air pressure line of the solenoid valve 8, and the air pressure path of the solenoid valve is controlled by the programmable logic controller (PLC) 9 program according to the predetermined setting time Interval on-of...
