| Abstract: | The production technology of one-step POY/FDY polyester intermingled yarn(ITY) is discussed fromthespin-pack pressure,coolingwindspeed,spinningspeed,spin-draw ratio,hot-rollertemperature,interlaced pressure, etc. Production practices show when the spin-pack pressure of POY and FDY are 12 MPa and 13 MPa, cooling wind speed is 0.65~0.75 m/s, spinning speed is 3 800~4 000 m/min, the firsy hot-roller(HT1) temperature is 94~97 ℃, the second hot-roller(HT2) temperature is 133~136 ℃, spin-draw ratio is 2.7~2.9, the middle interlaced pressure is 0.50~0.55 MPa, the main interlaced pressure is 0.55~0.60 MPa,the industrial production and the next processing production can be achieved. |
