Abstract
The invention provides a non-aqueous solvent composition with temperature control separation performance for active dye. The composition comprises good solvent of the active dye and poor solvent of active dye, wherein the volume ratio of the good solvent to the poor solvent is 1: (3-20); the good solvent of the active dye is the non-aqueous solvent capable of dissolving the active solvent and not having chemical reaction with the active dye; the poor solvent of the active dye is the non-aqueous solvent not capable of dissolving the active dye and not having chemical reaction with the active dye. The solvent system has advantages that after one dye period is ended, a purpose for separating the solvent can be achieved only by reducing the temperature of the solvent, the two solvents can be automatically separated after the temperature is lowered and can be recycled, and the mixture of the solvent does not need to be separated by adopting the energy-consuming and time-consuming distilling procedure, so that the cycling time is greatly reduced, the energy consumption is reduced, and the dyeing cost is remarkably reduced.
