Embodiment 1
[0020] When polyester filaments are placed in a water steamer, the water temperature is 90°C, and the others are the same as above.
Embodiment 2
[0022] Polyester filaments are placed in the natural state for 15 hours to pre-set, and the others are the same as above.
[0023] The present invention first measures the stretchable maximum of rayon, that is, the maximum pressure value that can be applied to it. Since the tensile strength of rayon is weaker than that of polyester filament, the maximum pressure value that can be applied to rayon is used for blending. It can ensure that the tension of rayon and polyester filaments is within its acceptable range, and they are not easy to break; further, before the mixed spinning, the polyester filaments are pretreated, so that the rayon and polyester filaments The characteristics are more consistent, which is conducive to the subsequent process.
