This invention discloses a method for producing high-quality blended yarn. Polyester and viscose fibers are sequentially and independently processed through opening and cleaning to obtain polyester and viscose fiber streams. These streams are then fed to a mixing feeder according to the required blending ratio using a cotton distributor. The mixing feeder is equipped with rear, middle, and front cotton boxes. The blended fiber streams are vibrated and tumbled in the upper rear cotton box before being conveyed to the lower rear cotton box. There, they are uniformly processed and laid flat on the conveying curtain while maintaining a uniform density before being conveyed to the middle cotton box. In the middle cotton box, the two fibers are vertically grasped and mixed by a corner nail curtain along the thickness direction. The fibers are then conveyed to the front cotton box by the corner nail curtain. There, they are uniformly processed and vibrated for uniform output. The yarn then directly enters a single-beater lap machine to produce a polyester-viscose blended lap. The yarn is then finely carded, impurities removed, and slivered by a carding machine. It is then uniformly processed by two drawing frames, drafted and twisted by a roving frame, and drafted and twisted by a spinning frame to form the desired blended yarn.
