Example Embodiment
[0007] The technical solutions of the present invention are further described in detail below through the examples.
[0008] This example is the process flow of super coarse denier polyester filament:
[0009] POY → yarn frame → wire cutter → first roller → twist stopper → first hot box → cooling plate → false twist device → second roller → network device → auxiliary roller → second heat box → third roller → probe Threader→oiling roller→winding→inspection→packaging
[0010] The processing method is completed by spinning and texturing. In order to achieve the effect of high elasticity, the false twisting process adopts the method of closing the second hot box.
[0011] The above example is an ultra-coarse denier processing process. The POY processed by spinning is inspected and balanced and sent to false twist. The raw yarn is fed through the first roller, and then enters the twist stopper to stop the twist. After being stretched in the first hot box, it is cooled by the coo...
