Method of spinning laundry, control device for laundry treatment apparatus, laundry treatment apparatus and computer program

The invention relates to a method of spinning laundry. The method comprises the following steps: continuously measuring the conveying flow of an lye pump; performing first stable spin-drying, whereinthe spin-drying rotating speed of a roller is kept constant within the resonance frequency range of a vibration system, and the lye pump operates in a stable spin-drying operation mode matched with the first stable spin-drying; and performing rising spin-drying, wherein the rising spin-drying starts according to the conveying flow rate of the lye pump and has a first rotating speed slope of the roller and a subsequent rotating speed slope starting according to the conveying flow rate of the lye pump, and the rotation speed slope is adjusted at least once according to the conveying flow above the resonance frequency range of the vibration system, so that the lye pump operates in a non-dry manner and no unpermitted backflow of the fluid occurs in the lye container. When the conveying flow isreduced, the rotating spe
