The invention relates to rayon and polyester filament blended spinning technology. The technology is characterized by including the following steps: 1) placing polyester filaments in a water steaming box for steaming at the water temperature of 85-100 DEG C for 80 minutes; 2) disposing the polyester filaments treated in the step 1) under the natural state for presetting for 10-20 hours; 3) measuring high limit in stretchability of rayon, namely a value of the maximum appliable pressure to the rayon; 4) adopting a water-jet loom for performing blended spinning on the rayon and the polyester filaments with the maximum pressure value.
