Embodiment Construction
[0007] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0008] Such as figure 1 Said, a production method of energy-saving FDY / POY composite yarn, comprising tow one 1, tow two 2, guide plate 3, lower hot roller group 4, upper hot roller 5, splitting roller 6, main network Device 7, composite yarn 8, it is characterized in that described tow one 1 passes through guide disc 3, then passes through dividing roller 6, finally enters main network device 7, and described tow two 2 passes through lower heat roller group 4, After passing through the upper heating roll 5 and the splitting roll 6, it finally enters the main networker 7, where the tow one 1 and tow two 2 are compounded at the main networker 7 to form a composite yarn 8.
[0009] In the energy-saving FDY / POY composite yarn production method of the present invention, the POY tow does not need to pass through the upper heating roller, which ensures the physica...
