Embodiment
[0009] Embodiment: A kind of different shrinkage two-component network composite yarn, which is composed of pre-oriented yarn 1 and fully drawn yarn 2. The pre-oriented yarn is composed of 8 to 144 filament fibers, and the cross-section of the pre-oriented yarn is It is in the shape of "rice", the fully drawn yarn is composed of 8 to 96 filament fibers, and the cross section of the fully drawn yarn is in the shape of "ten".
[0010] The production process of this example is as follows:
[0011] Pre-oriented yarn (POY) and fully drawn yarn (FDY) are obtained by drying the raw material, melting the screw, discharging the wire from the assembly, cooling by side air blowing and drawing by the godet;
[0012] In the process of producing pre-oriented filament 1, the components used in the component filament discharge link have a "meter"-shaped hole on the spinneret; in the process of producing fully drawn filament 2, the components used in the component filament discharge link The ...
